Assistance Building A Query...
Jun 15, 2006
I am trying to generate some datasets with some queries...
With a given series information, it should return PART_NOs that has STD
= 1 and a unique price at that particular 'START', and keeping the
'TYPE' in consideration...
DB examples below:
Main DB
IDPART_NOSERIESSTD
1A-1A1
2A-2A1
3A-3A1
4D-1D1
5D-2D0
Price DB
IDPART_IDTYPESTARTPRICE
501X100050
511X1000040
521Y100060
531Y1000050
542X100050
552X1000040
562Y100060
572Y1000050
582X100090
etc.
main.ID and Price.PART_ID are paired together.
So in an example case, lets say I am querying for SERIES A, with TYPE
X. A table should be outputted something like
PART_NO
A-1100050
A-11000040
A-3100090
Note how it skipped printing A2 because the price is the same as A1.
I'm really looking for the SQL code here... I can't get it to filter on
distinct price.
SELECT MAIN.PART_NO, PRICING.START, PRICING.PRICE
FROM MAIN, PRICING
WHERE (MAIN.SERIES LIKE 'A')
AND (MAIN.STD = '1')
AND (PRICING.PRICE != '')
AND (PRICING.TYPE = 'X')
AND (MAIN.ID = PRICING.PART_ID)
I've been trying to use GROUP BY and HAVING to get what I need but it
doesn't seem to fit the bill. I guess I'm not terribly clear on how I
can use the SQL DISTINCT command...? If I try and use it in my WHERE
statement it gives me syntax errors, from what I understand you can
only have distinct in the select statement? I'm not sure how to
integrate that into the query to suit my needs.
Thanks for any help.

The View SQL below takes 1:50 minutes to execute. I am looking for a way to improve processing time and keep the view select statements as simple as possible.
One part of the view that could be restructured is the lookup for the current term (TERM_TBL - bolded). When I hard code the current term my execution time drops to about 13 seconds
There are three possible values for the current term; one for each of our three acedemic careers (UGRD, CONT, & EXED). Could this information be looked up once and then each enrollment selected based upon the appropriate academic career current term value? If so, how would it be restructured? Currently, the lookup is done for every enrollment record.
There are no common fields between the NAMES table and the TERMS_TBL.
Code Snippet
SELECT A.EMPLID, A.LAST_NAME_SRCH, A.FIRST_NAME, A.MIDDLE_NAME, A.LAST_NAME
FROM NAMES A
WHERE A.EMPLID IN (
SELECT DISTINCT B.EMPLID
FROM STDNT_ENRL B
WHERE B.INSTITUTION = 'AAAAA'
AND B.STRM >= (
SELECT DISTINCT T.STRM
FROM TERM_TBL T
WHERE T.INSTITUTION = B.INSTITUTION
AND T.ACAD_CAREER = B.ACAD_CAREER
AND T.TERM_BEGIN_DT <= GETDATE()
AND T.TERM_END_DT >= GETDATE())
AND A.EMPLID NOT IN (
SELECT DISTINCT C.EMPLID
FROM SRVC_IND_DATA C
WHERE C.INSTITUTION = 'AAAAA'
AND C.SRVC_IND_CD = 'DPL' )
AND A.NAME_TYPE = 'PRI'
AND A.EFFDT = (
SELECT MAX(D.EFFDT)
FROM NAMES D
WHERE D.EMPLID = A.EMPLID
AND D.NAME_TYPE = 'PRI'
AND D.EFFDT <= GETDATE() )
Any suggestions will be gladly accepted. Keep in mind that the new and much improved must be legal within the context of a view select statement.
Thanks,
Steve

I am trying to build a related article display. I have a SQLDataSource that I want to be able to select information (Category) from the table (Articles) based on a querystring (ID). SELECT [Category] FROM [Articles] WHERE ([ArticleID] = @ID) which for an example, lets say ID = 1, and it results as Category = Health.That is easy enough, but how would I then select all columns from the table WHERE Category = Result of first SELECT? SELECT * FROM [Articles] WHERE ([Category] = ??? Result of prior select) Can this be done in 1 select command, or would a store procedure need to be written? I am a little lost, sincr I am using a SQLDataSource, and it will be displayed with a Repeater. Thanks!

First off, here is my query:SELECT DeviationDist.DEVDN, DeviationDist.DEVDD, DEVDA, DEVCT, DEVST, DEVBG, DEVDV, DEVPS, DEVAT, DEVCN, DEVCF, DEVCP, DEVCEFROM DeviationDistINNER JOIN DeviationContact ON DeviationContact.DEVDN = DeviationDist.DEVDNWHERE DeviationDist.DEVDN = '200270'ORDER BY Deviationdist.DEVDN DESCI'm joining the deviationcontact table to the deviation dist table by DEVDN. This query works fine except when the DeviationContact table doesnt contain any records for the DEVDN that the DeviationDist table does contain. In my app, Deviationdist will always have an record for each DEVDN, but DeviationContact may not. I would like to still get the results back for what records exist in the DeviationDist table, even if DeviationContact has no associated records, but still show them if it does...

Hi,
I have a need to renumber or resequence the line numbers for each unique claim number. For background, one claim number many contain many line numbers. For each claim number, I need the sequence number to begin at 1 and then increment, until a new claim number is reached, at which point the sequence number goes back to 1. Here's an example of what I want the results to look like:
ClaimNumber LineNumber SequenceNumber
abc123 1 1
abc123 2 2
abc123 3 3
def321 5 1
def321 6 2
ghi456 2 1
jkl789 3 1
jkl789 4 2
So...
SELECT ClaimNumber, LineNumber, <Some Logic> AS SequenceNumber FROM MyTable
Is there any way to do this?
Thanks,
Dennis

I realize this query is inherently incorrect, but my issue is mainly syntax. The line, "WHEN a.order_id <> b.order_id THEN" is wrong. I want to ensure that a.order_id is not in the settlement table. So I was thinking something along the lines of "WHEN a.order_id not in (select order_id from settlement)" which I know will cause a slower response time, but I'm willing to deal with it. In any case, that syntax doesn't appear to work.
sum(
CASE
WHEN a.ready_to_pay_flag = 'Y' and a.deduction_type = 'E' and (
CASE
WHEN a.order_id <> b.order_id THEN
a.transaction_date
ELSE
b.delivery_date
END) used_date datediff(d,used_date, ".$cutOffDate.") < 30) THEN
a.amount
END) earn_amount_rtp_curr,
Any help here would be hotness!

I am trying to get a running total. I need the query to reset the running total for each year/id. Below is the sample query. Any help would be greatly appreciated.
Code:
CREATE TABLE #valueset (k1 int, date datetime, groupByThis nvarchar(50), c1 int)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13024, '09/14/2007', '2007', 1)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13025, '09/15/2006', '2006', 1)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13025, '10/13/2006', '2006', 1)
INSERT #valueset (k1, date, groupbythis, c1) VALUES (13025, '09/14/2007', '2007', 2)
SELECT v.k1, v.date, v.groupByThis, v.c1, RunningTotal=SUM(a.c1)
FROM ( SELECT k1, date, groupByThis, c1, RANK() OVER (PARTITION BY k1 ORDER BY groupbythis, date) as Rank
FROM #valueset ) v
CROSS JOIN
( SELECT k1, date, groupByThis, c1, RANK() OVER (PARTITION BY k1 ORDER BY groupbythis, date) as Rank
FROM #valueset ) a
WHERE a.Rank <= v.Rank
AND a.groupByThis = v.groupByThis
GROUP BY v.k1, v.date, v.groupByThis, v.c1
ORDER BY v.groupByThis, v.date
Drop Table #valueset
Expected Results:
k1 date groupbythis c1 RunningTotal
13025 2006-09-15 00:00:00.000 2006 1 1
13025 2006-10-13 00:00:00.000 2006 1 2
13024 2007-09-14 00:00:00.000 2007 1 1
13025 2007-09-14 00:00:00.000 2007 2 2
13025 2007-11-09 00:00:00.000 2007 1 3
I am almost there - any help would be great. I need to reset the running total after every "groupbythis" for every "k1"
Thanks.

I am relatively new to the use of coplex queries. Here is a task that I am trying to accomplish.
Source table.
Address

WS1
Test-b
2
WS1
Test-a
5
WS2
Test-d

I am trying to write a query that will display this result into Excel.
Address
Duplicate
WS1
WS2
Test-a
Yes
1
5
Test-b
Yes
2
7
Test-d
No
Basically I am trying to identify if there is a duplicate address, if so mark it as such in the duplicate column and then placing the ID into a column under the Workstation.
I only want to see the duplicated address once (Distinct?) but mark that it is indeed a duplicate and mark the ID's that it has under the workstations.
Any ideas? I have created a query that does pull the data in the first example that is doing a DTS export to excel. However I need to format this to show the second example.
I appreciate any help I can get on this.

Hello,
I have two tables, USER and ROTATION. What I would like to display is the Maximum Start_Date and Maximum End_Date from the ROTATION Table along with the First_Name and Last_Name that is associated with that max entry.
When I just create a select statement that asks for the max value of the Start_Date and End_Date, I get the value I see. However when I try to add the First_Name and Last_Name to the mix, I get the Max Start and End Date Values of all the people in the User Table. I only want one result returned. I'm probably missing something very simple here. Any assistance would be appreciated.
The SQL code I am currently using:
Code SnippetSELECT [USER].FIRST_NAME, [USER].LAST_NAME, MAX(ROTATION.ONCALL_START_DATE) AS Expr1, MAX(ROTATION.ONCALL_END_DATE) AS Expr2
FROM ([USER] INNER JOIN
ROTATION ON [USER].USER_ID = ROTATION.USER_ID)
GROUP BY [USER].FIRST_NAME, [USER].LAST_NAME
Example of my desired result:
First_Name Last_Name OnCall_Start_Date OnCall_End_Date
John Doe 8/10/08 8/17/08
John Doe should be the only result returned because he would have the highest OnCall_Start and OnCall_End in the ROTATION Table.

I am new to SQL and aftering reading my SQL For Dummies book, I still am unsure how to accomplish this task.
The table I need to query contains resident census information. There are multiple rows for each resident. I need to determine if the resident is still active, so I only need to read the last row for each resident to make this determination.
What method can I use to read only the last row for the resident. Here is what I tried previously, but it returns multiple rows for each resident.
select a.firm_id_code as FacAddOnNum,
f.shortname as FacName,
left(a.resident_code,6) as ResidentCode,
(r.res_first_name + ' ' + r.res_last_name) as ResidentName,
a.LastDate,
a.cens_trans_type
from (select firm_id_code,
resident_code,
max(dt_cens_trans) as LastDate,
cens_trans_type
from arrescensus
where firm_id_code = @FacId
group by firm_id_code, resident_code, dt_cens_trans, cens_trans_type) as a
join corp_info.dbo.facilityinfo as f on (a.firm_id_code = f.addonnum)
join arresidents as r on ((r.firm_id_code = a.firm_id_code) and (r.resident_code = a.resident_code))
Any help with this is greatly appreciated!

I've got a website with dynamic content, each page (subject) got an ID. On every page there can be a number of links. These are either links to internal other pages on that website or external links.
For the internal links the only thing I need is the ID and Title of that page. Those can be found in the Tbl_subjects. As for external links I need ID, Title and URL which can be found in the Tbl_ext_links.
I've got a table named Tbl_linkboxes with:
- a Subject ID which means that this link belongs on this subject page.
- Link ID which is either an ID from Tbl_subjects or Tbl_ext_links
- External a boolean column to indicate if the Link ID refers to the Subject table or the External links table
There's basically 2 questions:
1) How to make this work? I've got a query below as feeble attempt
2) Should I really really really consider to use 2 columns for IDs and removing the External boolean. And simply setting one of those fields in the columns to >0 while the other is 0.
Okay, here's my attempt
PHP Code:
SELECT s.Sub_id, s.Link_id
(l.external IS FALSE, (SELECT Title FROM Tbl_subjects), (SELECT Title,URL FROM Tbl_ext_links)
FROM Tbl_subjects s
WHERE s.Sub_id = <some id>
Not sure if I should work with IIF here to make it work or something else. I'm almost tempted to kick the boolean column overboard and introduce a JOINT on both columns then, one for external link ids and other for internal page ids.
Amazing how long one can stare at a query and not being able to get it right

I'm attempting to write and update query. So far I have written the following:
update vwDISTCITY_TAXCODE
set tax_code='04'
where DIST_CITY='04'AND year_id=2007 AND frozen_id=0 AND p_id=93549 AND total_taxes=isnull
The last part of the query "total_taxes=isnull" is where the problem lies. Essentially I want to say if all of the other things are true and there is a null value in the total_taxes column, then I I want to set the tax_code to '04'. However how would I phrase the last part correctly?
Thanks!

Good Day;I would appreciate assistance developing a query that I haven't beenable to develop without using a second table. I wish to count thenumber of records that are still open on the first of each month.Each record has an open date and a close date or the close date isnull i.e., the record is not yet closed. I've previously beaten thisby building a table, simply a list of the dates for the first of eachmonth for the next ten years or so, and then selecting values basedupon a date selected from that table. However I'd be happier if Icould do it without the second table. I'd be prepared to accept theMin(Date) for each month as being the first of the month.I've included some DDL statements to build and populate the table ifthat helps. Since the selection is rather small and all the opendates are very close together I think the result will be simply adecreasing count from the month the first record is opened till today.A pseudo code select statement might look likeSelect Min(DateOpened) As DateOfInterest, Count(*) as [Qty Still Open]FROM DetailTWhere DateReceived > DateOfInterest or DateReceived is Null andDateOpened < DateOfInterestGroup by Min(DateOpened)Order by Min(DateOpened)I hope I've explained it sufficiently well.CREATE TABLE [dbo].[DetailT] ([Autonum] [int] IDENTITY (1, 1) NOT NULL ,[QDNumber] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[DateOpened] [smalldatetime] NOT NULL ,[DateReceived] [smalldatetime] NULL ,)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C15788', '06/04/2005 9:35', 07/04/2005)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B16091', '06/04/2005 9:36', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B15001', '06/04/2005 9:51', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('M18696', '06/04/2005 9:56', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C14969', '06/04/2005 10:05', '10/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('O10091', '06/04/2005 10:08', '12/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('D01197', '06/04/2005 10:13')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('H15001', '06/04/2005 10:15', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('J15090', '06/04/2005 10:24', '08/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('J01202', '06/04/2005 10:31')Insert into DetailT (QDNumber, DateOpened)VALUES('G01193', '06/04/2005 10:32')Insert into DetailT (QDNumber, DateOpened)VALUES('K01164', '06/04/2005 10:35')Insert into DetailT (QDNumber, DateOpened)VALUES('K01162', '06/04/2005 10:48')Insert into DetailT (QDNumber, DateOpened)VALUES('F01124', '06/04/2005 10:59')Insert into DetailT (QDNumber, DateOpened)VALUES('H01147', '06/04/2005 11:01')Insert into DetailT (QDNumber, DateOpened)VALUES('S15068', '06/04/2005 11:10')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('E12322', '06/04/2005 11:32', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('A12205', '06/04/2005 11:37', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('D12259', '06/04/2005 11:40', '07/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('C03394', '06/04/2005 11:51')If you made it this far thank you for your patience.

I have a query that gets three columns of data. PRODUCT_ID, SMALL_TEXT_VALUE, AND LARGE_TEXT_VALUE. I'd like to know if there is a way that I can alter my query below so that whenever SMALL_TEXT_VALUE is Null, it uses the value thats in the LARGE_TEXT_VALUE column. Whenever the small is null, the data I need is in the large column. My Query: Select EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID, EXTENDED_ATTRIBUTE_VALUES.SMALL_TEXT_VALUE, EXTENDED_ATTRIBUTE_VALUES.LARGE_TEXT_VALUEFrom EXTENDED_ATTRIBUTE_VALUES, EXTENDED_ATTRIBUTESWhere EXTENDED_ATTRIBUTE_VALUES.Ext_Att_ID = EXTENDED_ATTRIBUTES.Ext_Att_IDORDER BY Product_ID DESC

I got some help on here before with building my query. I thought this was working fine but it turns out when there are multiple records for a column type, it only grabs the first one. I need to get all records. Is there an alternative to MAX? I needed to structure it like this because I needed to return each row as a column and this was the way suggessted before.
My query:SELECT TOP (100) PERCENT PRODUCT_NUMBER, PRODUCT_NAME,
MAX(CASE WHEN ColumnName = 'Federal Specification Number' THEN TheValue ELSE NULL END) AS [Federal Specification Number]FROM (SELECT dbo.PRODUCT_FEATURE_VALUES.PRODUCT_ID AS ProductID, dbo.SHARED_FEATURE_VALUES.FEATURE_TEXT_VALUE AS TheValue,
dbo.SHARED_FEATURE_TYPES.FEATURE_TYPE AS ColumnName, dbo.PRODUCTS.PRODUCT_NUMBER, dbo.PRODUCTS.PRODUCT_NAME
FROM dbo.PRODUCT_FEATURE_VALUES INNER JOINdbo.SHARED_FEATURE_TYPES ON
dbo.PRODUCT_FEATURE_VALUES.FEATURE_TYPE_ID = dbo.SHARED_FEATURE_TYPES.FEATURE_TYPE_ID INNER JOINdbo.SHARED_FEATURE_VALUES ON
dbo.PRODUCT_FEATURE_VALUES.FEATURE_VALUE_ID = dbo.SHARED_FEATURE_VALUES.FEATURE_VALUE_ID INNER JOINdbo.PRODUCTS ON dbo.PRODUCT_FEATURE_VALUES.PRODUCT_ID = dbo.PRODUCTS.PRODUCT_ID
UNIONSELECT dbo.EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID AS ProductID, ISNULL(dbo.EXTENDED_ATTRIBUTE_VALUES.SMALL_TEXT_VALUE,
dbo.EXTENDED_ATTRIBUTE_VALUES.LARGE_TEXT_VALUE) AS TheValue, dbo.EXTENDED_ATTRIBUTES.COLUMN_NAME AS ColumnName, PRODUCTS_1.PRODUCT_NUMBER, PRODUCTS_1.PRODUCT_NAME
FROM dbo.EXTENDED_ATTRIBUTE_VALUES INNER JOINdbo.EXTENDED_ATTRIBUTES ON
dbo.EXTENDED_ATTRIBUTE_VALUES.EXT_ATT_ID = dbo.EXTENDED_ATTRIBUTES.EXT_ATT_ID INNER JOIN
dbo.PRODUCTS AS PRODUCTS_1 ON dbo.EXTENDED_ATTRIBUTE_VALUES.PRODUCT_ID = PRODUCTS_1.PRODUCT_ID) AS t1
WHERE PRODUCT_NUMBER = '02083'
GROUP BY PRODUCT_NUMBER, PRODUCT_NAME
ORDER BY PRODUCT_NUMBER
This returns:
Product_Number Product_Name Federal Specification Number
02083 Di-Electric Grease, 10.5 Wt Oz FDZ-CFR-21-178.3570
There is another record for Federal Specification Number I need to return as well. If I change to MIN, it gets the other record. Anyway I can get both?

I have two tables that are pretty standard I think. Table a has product descriptions and one of those fields is a price. I have a second table that contains fees based on the price. so table B looks like this.
min max fee
0 19.99 2.50
20.00 49.99 3.50
50.00 1000.00 5.50
the max ends up around a million just to be sure we cover all prices. my problem is this I need a very efficient query to
poll all the values from A and the correct value from B. All the attempts I have made are not working. I also have to make sure this query is extremely efficient as it is executed several times a minute. If there is a better way in general to structure this I am all ears. I wanted to avoid placing the fees in the product table as the fees are updated often, but if its the only way to get this to work, then that is where I will go.
Thanks everyone

Hello,
This will probably be trivial and basic for most, but I'm having a hard time trying to figure out the best way to do a SELECT statement. First, let me explain what I have:
Two tables:
Table 1:
Orders
Some of the fields:
ID
PropID
WorkOrderNum
OrderDesc
DateCompleted
Table 2:
OrderDetail
ID
OrderID
TenantName
As you probably have realized, the OrderID in my 'OrderDetail' table corresponds to the ID field in my 'Orders' table. The 'Orders' table contains the order header information, while the OrderDetail contains line items for that order - 1 line item per record.
Here is my SQL statement to retrieve an order when searching by the 'Order Description' (Orders.OrderDesc):
SELECT PropertyLocations.PropertyLocation, Orders.ID, Orders.PropID, Orders.WorkOrderNum, Orders.OrderDesc, Orders.DateCompleted FROM PropertyLocations, ORDERS WHERE PropertyLocations.ID = Orders.PropID AND OrderDesc LIKE '%lds%'
Ok, so now for the 'big' question/problem: I also need to be able to search the 'Tenant Name' field from the 'OrderDetail' table. So what is the best/most efficient way of doing that? The other stipulation about that is that there can be (and usually is) several records/line items (in the OrderDetail table, of course) that contains the same (or similar) data, but I don't want duplicates. And when I say duplicates, all I care about is retrieving a few fields (as you can see from my SQL statement) from the 'Orders' table. Another way to describe what I want is that I want all unique orders that have a 'TenantName' in the 'OrderDetail' table that matches the search criteria. My brain just isn't wanting to figure this out right now, so I was hoping someone could help me out.
thanks.

Hi there,
i have a query building question and was hoping that one of you would know the answer.
Here is what i need to do :(i am using asp.net and ado.net)
I have 1 table where I store thedata, where 5 criteria determine a unique row in this table. Now, this has recently changed as the start date was added. So there potentially can be more than one entry in the table with same 5 criteria, but different start date.
I need to retrieve the row with the latest start date (currently active). The problem arises when the users enter less than 5 criteria. In this case the results may not possess same 5 criteria. Say the user searches based on 2 criteria. Then all the rows possessing these 2 ctieria will be returned, but other 3 criteria might differ with the results set.
But, i only need the latest start date row for each row. So for example, if i searched on 2 criteria, i got back 4 rows, 2 of which possess the same 5 criteria. But between these 2 i only need to display ONE row to the user - the one with the latest date.
How do i build a query? say the table name is tbl, and criteria 1 to 5 fields are called c1 ... c5, and start date field is called start_date.
thanks in advance

I am hoping someone can point me in the right direction with this.I have query that returns all the colums in a row (SELECT * FROM table WHERE value = 'value') and I need to build a table with this data. Some of the columns may not have values in them, and so I dont want to build a table row for it. I also need to use the column name as the table header. As an example:==============================Column Name || Column Value-----------------||-----------------Column Name || Column Value
-----------------||-----------------
I hope I have explained myself properly. Any help would be greatly appreciated.

Good Afternoon!
I have a (hopefully) simple question.
I have recently been bumped into an applications developer position. I took a week of ASP training a few months ago, but outside of that my exposure to ASP and SQL has been EXTREMELY limited.
I just undertook my first project using these skills. We have an application where I track "Letters". I fill out a form with information regarding the Letter, and save it so there is a record of the letters existence and what its status is.
Afterwards, we want to update the status, so I find the saved form, make my edits, and save it.
This is where my problem starts.
When I first save the letter, I have no problems whatsoever.
When I save it a second time after making my edits, I get an error:
Microsoft OLE DB Provider for SQL Server error '80040e14'
Line 1: Incorrect syntax near 'yearID'.
/AuditFlowChart/UpdateAudit.asp, line 206
What I am doing with the ASP is basically created a SQL statement to update the table with the new letter information. I added a line to print out the store proceedure that is being created by the following line
Set rsRecordsetObject = objCOMComponentClassObject.ExecuteSQLStatement(spStoredProcedure,vntSQLServerName,dbDatabaseCatalog)
I print out spStoredProcedure and I get the following
UpdateCorrespondence @p_idCorr = 416,
@p_dtOfLetter = '8/7/2008',
@p_dtRcvdByRespAtty = '2/19/2007',
@p_dtRcvdByAdmin = '2/23/2007',
@p_descOfEntity = 'This is a test 2009 letter. Dated 2/8/2007',
@p_ClientCode = '01074',
@p_MatterCode = '0055',
@p_dtDue = '3/15/2007',
@p_dtEffective = '4/18/2007',
@p_dtYE = '4/8/2007',
@p_respAtty = '0330',
@p_respAttyFull = 'Abelson, H. Edward',
@p_prepParalegal = 'Aldous, Anne Marie',
@p_prepAtty = 'Abromowitz, David',
@p_prepLitParalegal = 'Allegrini, J. Samuel',
@p_dtGivenToParalegal = '4/20/2007',
@p_dtGivenToAtty = '2/28/2007',
@p_dtMemoCirculated = '2/18/2007',
@p_dtRespSentToLitParalegal = '2/10/2007',
@p_dtRespSentToPrepAtty = '2/26/2007',
@p_dtSentToAccountant = '2/15/2007',
@p_memoDSid = 1111111,
@p_respLetterDSid = 2222222,
@p_sideLetterDSid = 3333333,
@p_comments = NULL,
@p_yearID = rsLetterDetail1('yearID'),
@p_opinion = 1,
@p_complete = 0,
@p_userID = 'GSSUSO1517'
When I run the above thru Query Analyzer, I get the following:
Server: Msg 170, Level 15, State 1, Line 26
Line 26: Incorrect syntax near 'yearID'.
So now I know where my error lies, but I am not sure where to look next. Does anyone have any ideas? Is there a problem I am not seeing with the query?
Any help would be wonderful and much appreciated.

Hi,
I'm using 2005 management studio express.
Can I use the graphical query builder to specify tables from more than one database?
I know I can do this in sql in the format database..table.column but in the query builder it only shows tables from the current database. Can you get around this?
Thanks

Hi,
Does anybody know if it is possible to obtain an alias from a Query without using Dynamic SQL.
My Problem Looks like this:
CREATE TABLE Source (SourceName varchar(50), SourceAge int)
INSERT INTO Source VALUES ('Mary',41);
INSERT INTO Source VALUES ('John',22);
INSERT INTO Source VALUES ('Tom',15);
INSERT INTO Source VALUES ('Bill',55);
The Statement should look like This:
SELECT A.SourceAge AS A.SourceName FROM Source A;
The Result should look like this:
Mary John Tom Bill
----------------------------------------
41 22 15 55
Thanks in advance

Hiya,
This is a fairly detailed problem, so this will be a long post... I do appologize. I have been agonizing over this now for over a week and cannot find a viable solution. Hopefully one of you can help.
First off, I work for a realestate company, and this query will display a list of properties based on a number of different criteria and criteria types. There are multiple tables involved:
dbo.Prop:
Property Database. Holds basic info about each property
dbo.Prop_Features:
holds all the features (such as Pool, Carpet, Drapes etc) for each property. The only information stored in this table are PropID and FeatureID (PropID being the Identity of the Prop table, FeatureID being the Identity of the Features Table)
dbo.Features
Holds information on each possable "feature" in the system.
dbo.Members
Holds basic information and criteria for each of our members.
dbo.Members_Features
This table holds the MemberID and FeatureID where members have chosen one ore more features to be used for criteria when searching for a property.
Ok, now... That said, here is my problem. The query I had written (by a professional hired thru Robert Half Technologies) takes over 30 seconds to execute. I will post a copy of that SP below. This is unacceptable. We have to process thousands of these per hour, and a 30 second process time is very bad. Can any of you give me a idea of how to better approach this problem?
In the code below, you will notice there are other tables I did not mention - they are not important. The Speed problem is surrounding a single function, which I will mention below.

Okey, now. Please notice this part of that code:
dbo.Prop_Get_Feature_List_Fun(P.PropID) + CASE Len(P.CustomFeatures)
WHEN 0 THEN ''
ELSE ', ' + P.CustomFeatures
End
+ CASE Len(P.Comments)
WHEN 0 THEN ''
ELSE ', ' + P.Comments
End
AS 'Features',
This function is the cause of the speed problem, methinks. When run alone, it takes 29 seconds to process with the same MemberID that takes about 33 seconds to process completely (the whole Proc). This function simply returns a list of comma delimited features for each property, for displaying on a customer list. Here is that function:
CREATE Function dbo.Prop_Get_Feature_List_Fun (@PropID int)
RETURNS Varchar(3500)
AS
BEGIN
Declare @FeatureList Varchar(3500)
select @FeatureList = Coalesce(@FeatureList + ', ', '' ) + F.FeatureName
FROM
Prop P
INNER JOIN
Prop_Features PF
ON
P.PropID = PF.PropID
INNER JOIN
Features F
ON
PF.FeatureID = F.FeatureID
WHERE
P.PropID = @PropID
ORDER BY
F.FeatureName
Set @FeatureList = isnull(@FeatureList,'Please call for features.')
RETURN @FeatureList
END
Now, I know I probably gave lots more information then needed to solve this issue - but its better to have too much then not enough.
Any help at all in speeding up this function or describing another way to do this would be most appreciative.

I have a table that was created as follows
create table call_summary (
row_date smalldatetime,
[700] int,
[730] int,
[800] int,
[900] int)
I have a query that returns the following
date interval (int) calls (int)
2008-01-07 00:00:00 700 0
2008-01-07 00:00:00 730 0
2008-01-07 00:00:00 800 0
2008-01-07 00:00:00 830 9
2008-01-07 00:00:00 900 8
I am looking for a way to get my table mentioned above to look like this
row_date [700] [730] [800] [830] [900]
2008-1-7 0 0 0 9 8
does anyone have any slick ideas on how I can accomplish this task?

I have a class that works fine using the SQLDataReader but when I try and duplicate the process using a Dataset instead of a SQLDataReader it returnsa a null value.
This is the code for the Method to return a datareader
public SqlDataReader GetOrgID()
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
SqlConnection con = new SqlConnection(conString);
string selectString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlCommand cmd = new SqlCommand(selectString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
con.Open();
SqlDataReader dtr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
return dtr;
This is the code trying to accomplish the same thing with a Dataset instead.
public DataSet organID(DataSet dataset)
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
string queryString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlConnection con = new SqlConnection(conString);
SqlCommand cmd = new SqlCommand(queryString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;
adapter.Fill(dataset);
return dataset;
}
Assume that the conString is set to a valid connection string. The Singlton passes the userid in from some code in the code behind page ...this functionality works as well.
So assume that the Guid is a valid entry..I should return a valid dataset but its null.

Let me start by asking that no one try to convince me to use Stored Procs. The examples below are a lot more simplistic then my real world code and it just gets too complicated to try to manage the quantity of SPs that I would need.
I have an application that displays a lot of data and I've created a system for users to filter the data using checkboxlist controls, dropdown controls, etc. From this, I have a "core" query that selects the fields that display in my GridView. It has a base Select clause, From clause and Where clause. From this I then add more to the Where clause to apply these filter values.
Here's an example "core" query:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, ProjectWHERE Profile.ProjectCode = Project.ProjectCode
From this if a user want's to only display profiles from NC, they could select that from the CBL and the query would be modified to:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, ProjectWHERE Profile.ProjectCode = Project.ProjectCodeAND Profile.State IN ('NC')
My code would add the last line above since the user specified that they only wanted NC profiles.
This is very simple and I have this already going on with my application. Here's the problem. In order to accommodate all of the various filters, I have to inner join and left join a bunch of various tables. Many times I include tables that have no data to display or filter on and therefore impacts performance. Here's an example:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, Project, AgentWHERE Profile.ProjectCode = Project.ProjectCodeAND Profile.AgentID = Agent.AgentID
From the query above, I have included the Agent table that holds the agent's contact information. One of my filters allows the user to type in an agents name to find all profiles assigned to it. Here's what that would look like:
SELECT Profile.FirstName, Profile.LastName, Project.ProjectNameFROM Profile, Project, AgentWHERE Profile.ProjectCode = Project.ProjectCodeAND Profile.AgentID = Agent.AgentIDAND Agent.Name = 'Smith, John'
You can see now that it was necessary to have the Agent table already joined into the query so that when I used the agent name filter, it wouldn't crash out on me.
The obvious thing would be to only include the Agent table when searching for an agent name. This is ultimately what I'm looking to do, but I need a solid method to go about doing this. Keep in mind that I currently have 16 tables in my "core" query and many of those are not needed unless the filters call for it.
If anyone has any ideas on how to simplify this process I'm selcome to suggestions. We're using SQL 2000, but are looking to upgrade to SQL 2005, if that makes any difference. I know that the way I do table joins is compliant with SQL 2005 and I'm certainly open to suggestions that will make it forward compatible.
This app is using .NET 2.0 and written in VB.NET. Thanks for any help!

Hi i have a page whereby the user can make a search based on three things, they are a textbox(userName), dropdownlist(subcategoryID), and region (regionID). The user does not have to select all three, he or she can enter a name into the textbox alone and make the search or enter a name into the textbox and select a dropdownlist value, my question is how can i build this procedure, I tried this but it didnt work;
Code:
ALTER PROCEDURE [dbo].[stream_UserFind]
(
@userName varchar(100),
@subCategoryID INT,
@regionID INT
)
AS
declare @StaticStr nvarchar(5000)
set @StaticStr = 'SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName,
Users.userName ,UserSubCategories.userID
FROM Users INNER JOIN UserSubCategories ON Users.userID= UserSubCategories.userIDINNER JOIN
SubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHERE UserName like @UserName'
if(@subCategoryID <> 0)
set @StaticStr = @StaticStr + ' and SubCategories.subCategoryID = @subCategoryID '
if(@regionID <> 0)
set @StaticStr = @StaticStr + ' and SubCategories.RegionId = @regionID '
exec sp_executesql @StaticStr
)
