I have a couple of tables that look like this (not excactly but close
enough):
[Contact]
id int
fname varchar(50)
lname varchar(50)
[ContactPhoneNumber]
id int
number varchar(15)
ext varchar(6)
contact_id int
priority int (indicates primary, secondary... numbers)
type int (indicates type of number: fax, cell, land line)
I'm looking for a more optimized method of displaying this information
in this format:
fname, primary business phone
Using a derived column like this works, but seems to be slow with many
records, despite tuning indexes:
SELECT c.fname AS [First Name],
( SELECT TOP 1
number
FROM ContactPhoneNumber cpn
WHERE cpn.type = 1
AND cpn.contact_id = c.id
ORDER BY cpn.priority) AS Number
FROM Contact c
I can get the same results using a join, and it's a lot faster. But I'm
not sure how to select only the primary phone number this way...
basically the first phone number whose priority is either NULL or 1.
Any suggestions?

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...
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:
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,
I am trying to pull some "notes" from a sql database.....the notes thatare put into the database come via the web and the user is entering itfor a certain task. they are stored in their own table and field andget assigned and incremental ID #.I want to be able to pull up the latest entry to the task, not all ofthe notes just the latest one.. The entry does get a timestamp in thefield so I am thinking I might be able to look at that fieldsomehow.... Right now my query shows all notes / entries for the task.I am an intermediate sql query guy so I hopefully expained enough toget assistance.Let me know if you need to know more.
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.

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
I am relatively new to the use of coplex queries. Here is a task that I am trying to accomplish.
Source table.
Address ID Workstation
Test-a 1 WS1
Test-b 2 WS1
Test-a 5 WS2
Test-d 3 WS2
Test-b 7 WS2
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 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))
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?
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 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 DBIDPART_NOSERIESSTD1A-1A12A-2A13A-3A14D-1D15D-2D0Price DBIDPART_IDTYPESTARTPRICE501X100050511X1000040521Y100060531Y1000050542X100050552X1000040562Y100060572Y1000050582X100090etc.main.ID and Price.PART_ID are paired together.So in an example case, lets say I am querying for SERIES A, with TYPEX. A table should be outputted something likePART_NOA-1100050A-11000040A-3100090Note how it skipped printing A2 because the price is the same as A1.I'm really looking for the SQL code here...

I guess I'm not terribly clear on how Ican use the SQL DISTINCT command...? If I try and use it in my WHEREstatement it gives me syntax errors, from what I understand you canonly have distinct in the select statement? I'm not sure how tointegrate that into the query to suit my needs.Thanks for any help.

How to optimize the following Stored procedure running on MSSQL server 2000 sp4 :

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.
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.
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.
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.

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 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?
Hi, Can anyone help me optimize the SELECT statement in the 3rd step? I am actually writing a monthly report. So for each employee (500 employees) in a row, his attendance totals for all days in a month are displayed. The problem is that in the 3rd step, there are actually 31 SELECT statements which are assigned to 31 variables. After I assign these variable, I insert them in a Table (4th step) and display it. The troublesome part is the 3rd step. As there are 500 employees, then 500x31 times the variables are assigned and inserted in the table. This is taking more than 4 minutes which I know is not required :). Can anyone help me optimize the SELECT statements I have in the 3rd step or give a better suggestion. DECLARE @EmpID, @DateFrom, @Total1 .... // Declaring different variables SELECT @DateFrom = // Set to start of any month e.g. 2007-06-01 ...... 1st Loop (condition -- Get all employees, working fine) BEGIN SELECT @EmpID = // Get EmployeeID ...... 2nd SELECT @Total1 = SUM (Abences) ...... 3rd FROM Attendance WHERE employee_id_fk = @EmpID (from 2nd step) AND Date_Absent = DATEADD ("day", 0, Convert (varchar, @DateFrom)) (from 1st step) SELECT @Total2 ........................... same as above SELECT @Total3 ........................... same as above INSERT IN @TABLE (@EmpID, @Total1, ...... @Total31) ...... 4th Iterate (condition) to next employee ...... 5th END It's only the loop which consumes the 4 minutes. If I can somehow optimize this part, I will be most satisfied. Thanks for anyone helping me....
Trying to optimize a query, and having problems interpreting the data. We have a query that queries 5 tables with 4 INNER JOINS. When I use INNER HASH JOIN, this is the result:
(Using SQL Programmer)
SQL Server Execution Times: CPU time = 40 ms, elapsed time = 80 ms.
Now, when timing the code execution on my ASP page, it's "faster" not using the HASH. Using HASH, there are a few Hash Match/Inner Joins reported in the Execution Plan. Not using HASH, there are Bookmark Lookups/Nested Loops.
My question is which is better to "see": Boomark Lookups/Nested Loops or Hash Match/Inner Joins for the CPU/Server?
IS there any way to rewrite this Query in optimized way?
SELECT dbo.Table1.EmpId E from dbo.Table1 where EmpId in( SELECT dbo.Table1.EmpId FROM (SELECT DISTINCT PersonID, MAX(dtmStatusDate) AS dtmStatusDate FROM dbo.Table1 GROUP BY PersonID) derived_table INNER JOIN dbo.Table1 ON derived_table.PersonID = dbo.Table1.PersonID AND derived_table.dtmStatusDate = dbo.Table1.dtmStatusDate))
How can I optimized the following query: (SELECT e.SID FROMStudents s JOINTable1e ON e.SID= s.SID JOINTable2 ed ON ed.Enrollment = e.Enrollment JOINTable3 t ON t.TNum = e.TNum JOINTable4 bt ON bt.TNum = t.TNum JOINTable5 b ON b.Batch = bt.Batch JOIN IPlans i ON i.IPlan = ed.IPlan JOINPGroups g ON g.PGroup= i.PGroup
WHERE t.TStatus= 'ACP' ANDed.EStatus= 'APR' ANDe.SID=(select distinct SID from Table1 where Enrollment=@DpEnrollment)) AND(ed.EffectiveDate= (SELECT EffectiveDate FROM Table2 ed JOIN Table1 e ON e.enrollment=ed.enrollment WHERE IPlan = @DpIPlan ANDTCoord = @DpTCoord ANDAGCoord= @DpAGCoord ANDDCoord=@DpDCoord ) ANDDSeq= @DpDSeq) ANDe.SID= (select distinct SID from Table1 where Enrollment=@DpEnrollment)) ) ANDed.TerminationDate= (SELECT TerminationDate FROM Table2 ed JOIN Table1 e ON e.enrollment=ed.enrollment WHERE IPlan = @DpIPlan ANDTCoord = @DpTCoord ANDAGCoord= @DpAGCoord ANDDCoord= @DpDCoord ) ANDDSeq= @DpDSeq) ANDe.SID= (select distinct SID from Table1 where Enrollment=@DpEnrollment)) ) ))
DECLARE @PTEffDate_tmp AS SMALLDATETIME SELECT @PTEffDate_tmp = DateAdd(day, -1, PDate) FROM PDates pd WHERE iplan = @DIPlan and pd.TCoord = @DTCoord and DType = 'EF'
DECLARE @PTCoord_tmp as char(3) SELECT @PTCoord_tmp = tc.TCoord FROM PDates pd JOIN TCoords tc ON (pd.TCoord = tc.TCoord) WHERE pd.Iplan = @DIPlan and tc.TGroup = @TGroup_tmp and PDate = @PTEffDate_tmp and DateType = 'TR1'
DECLARE @EStatus_tmp as char(3) SELECT @EStatus_tmp = EDStatus From EDetails ed JOIN ENR e ON (ed.enr = e.enr) JOIN Trans t ON (e.transID = t.TransID) WHERE iplan = @DIPlan and ed.TCoord = @PTCoord_tmp and t.TransS= 'ACP' and DCoord = @DCoord and CEnr is null
How can I optimazed my query. Since my DB is more then 1 mln it takes a while to do all those join? select * FROM EEMaster eem JOIN NHistory nh ON eem.SNumber = nh.SNumber OR eem.OldNumber = nh.SNumber OR eem.CID = (Replicate ('0',12-len( nh.SNumber))+ nh.SNumber )
I work on tables containing 10 million plus records. What are the general steps needed to ensure that my queries run faster? I know a few: - The join fields should be indexed -Selecting only needed fields -Using CTE or derived tables as much as I can -Using good table reference eg select a.x , b.y from TableA a inner join TableB b on a.id = b.id
I will be happy if somebody could share or add more to my list.
Dear all, The below query take 7 min to execute so i want optimize the query.please any suggestions..........

LATEST column value changes for Row 1 since there is a repetition of value 124, meaning this row is no longer the latest.
NEW COLUMN value changes for ROW 2 since there it is no longer new; we already have an occurrence of 124 in the first row.
I m not sure if i can solve this query using any option other than cursor. it will be like taking first row --> comparing it with all the other rows and then moving further.
Plz. suggest me if there is a better approach for doing this
