Hi, I am a new learner and user to SQL Sever 2005 and am having some major frustration trying to write a simple query.
I have two tables, 1) Ticket_Purchase, 2) Flight.
The Ticket_Purchase table has these columns: Ticket_Purchase_Number(PK), Flight_Number(FK), Date_Purchase_Made, Ticket_Price, Class_of_Ticket, Passenger_ID
The Flight table has these columns: Flight_Number(PK), Flight_Date, Flight_Departure_Time, Flight_Arrival_Time, Flight_Origin, Flight_Destination
I am trying to create a query that will tell me: On which flight were the most first class tickets sold?
There are only two types of classes; 'E' for economy and 'F' for First Class.
So far I am able to get a list of all the First class flights for each flight and can visually see which flight has the most first class tickets by counting them manually on the report generated, but I am totally confused on how to simply pull the single flight with the most First class tickets sold. I wonder if this requires something more like a join or a nested sub query?
The SQL I wrote for the above is:
Select Class_of_Ticket, Flight_Number
From Ticket_Purchase
Where Class_of_Ticket = ('F')
Order By Flight_Number;
And it produces:
Class_of_Ticket Flight_Number
--------------- -------------
F 1
F 1
F 1
F 2
F 2
F 3

F 9

(38 row(s) affected)
Rather I would like it to produce:
First_Class_Seats Purchased Flight_Number
--------------------------- ------------
14 4
I hope I didn't make this to confusing to understand as I am still learning the syntax and 'lingo' of how to communicate this stuff verbally.
Thank you for any help you could offer. It would be much appreciated.
Edit: the query report I pasted from SQL should have the flight number directly under the column header. For some reason the space between Class and Flight_number is being eliminated in the post.
I am having in writing a simple select command........here's My ProblemI am using the ASP SQLDataSources in VS2005.... and my need is that i need to show Products details in a Gridview...... Actually through QueryString a StoreID is being fetched..... and the Products under those StoreID are shown..... if there is nothing in query string then it should show all the results... ........ It means that my querystring should be something like thisselect * from tblProducts where StoreID = <xyz>and <xyz> should be some thing that could show all the rows in that table ........ i mean that it should show all the possible results that can be shown through...select * from tblProducts
View 6 Replies View RelatedCan anyone help me with this strange problem please?I have a stored procedure, with a parameter defined as auniqueidentifier. The procedure does a select with a number of joins,and filters within the Where clause using this parameter.(@orderHeader_iduniqueidentifier)SELECT*FROM originalOrderHeader oohINNER JOIN originalOrderLine oolON ooh.id = ool.idFULL OUTER JOIN orderLine olon ool.id = ol.idAND ool.productCode = ol.productCodewhere (ooh.id = @orderHeader_id)There is a clustered index on the id column of originalOrderHeader,and on id and productCode of both originalOrderLine and orderLine.These indexes are regularly rebuilt. The execution plan shows a seekagainst these indexes, but the estimated row count values are huge,and should be single figures.If I change the SP to accept the parameter as a varchar, and thenexplictly cast back to a uniqueidentifier in the where clause, the SPruns much, much quicker, the execution plan is doing far less work,and crucially the estimated row counts on the clustered index seeksare correct (single figures).Does anyone have any ideas what might be causing this?

I am currently studying Transact SQL and playing around with queries from a sample database. Recently I created the following query.
USE MemtrackSQL
SELECT m1.MemberID, m1.Surname, m1.FirstName, m1.DateOfBirth
FROM tblMember m1 JOIN tblMember m2
ON m1.FirstName = m2.FirstName
WHERE m1.MemberID <> m2.MemberID
This simple query is designed to show all members with the same first name as other members. The result I got shows duplicates of existing members an inconsistent number of times even though I specified not to show duplicates with WHERE m1.MemberID <> m2.MemberID

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?
Hello all,
Thought I would post here in case anybody can give some information.
Here is the background information:
I have 2 tables (stores and sales) from the Pubs database in Sql Server 2000 copied down to a SQL Server CE database. There is no foreign key/primary key relationship between the 2 tables in the CE database.
Here are the update queries that cause the error:
UPDATE st
SET st.zip = 66668
FROM stores st
INNER JOIN sales sa ON st.stor_id = sa.stor_id
AND st.stor_id = 6380
Update stores SET stores.zip = 55555
FROM sales, stores
WHERE stores.stor_id = 6380
AND stores.stor_id = sales.stor_id
Here is the error message that is generated when I run the query (Param 0 and Param 1 change according to what column and line the FROM clause is in):
Error: 0x80040e14 DB_E_ERRORSINCOMMAND
Native Error: (25501)
Description: There was an error parsing the query. [Token line number,Token line offset,,Token in error,,]
Interface defining error: IID_ICommand
Param. 0: 2
Param. 1: 1
Param. 2: 0
Param. 3: FROM
Param. 4:
Param. 5:
I ran the 2 queries in SQL Query Analyzer in SQL Server 2000 and they worked just fine. I also created 2 new tables (stores1 and sales1) in SQL Server 2000 using the Select Into clause. The new tables were created from the sales table and stores table in the Pubs database. The new tables had no foreign key/primary key relationship.
I ran the queries again in Query Analyzer against the new tables and the queries produced no errors.
Any suggestions?
Thank you,

Okay, so I came across an odd performance issue that I'm wondering if some guru can help me out with.
I have a query that uses a paging algorithm that uses a paging algorithm and a table variable, then gets a page of data based on a join to that table variable. Here's a simplified query using the algoritm:
--declare table variable... not shown for brevity
--make sure we only store the least amount of records possible
SET ROWCOUNT ( @pageNumber + 1 ) * @pageSize
--insert into table variable
INSERT INTO @TableVariable( Key )
SELECT key FROM table
WHERE whatever = @p1
--we only want one page of data
SET ROWCOUNT @pageSize
--now get the page of data from the table
SELECT key FROM table
WHERE whatever = @p1
AND [TableVar Identity Column] > @pageNumber * @pageSize
The algorithm works great for our needs, BUT, I noticed something a little odd about its behavior during performance testing.
In particular, when I run the query using Sql Server Management Studio, where I manually DECLARE all the variables it ends up needing only 156 reads to complete the job. When I call it from the app using ADO.NET, however, I noticed it needs 310 reads! Huh?
I looked for differences, and the only one I could determine was that ADO.NET passes the query and uses sp_executesql and passes the parameters vs. declaring and setting them statically before executing the query. I confirmed that this was the issue by manually running sp_execute SQL and seeing that it took roughly the same number of reads (274) to process the query.
Naturally, I don't want the time it takes to perfrom my query to double, but and frankly I don't understand why there would be a difference in performance. Can anyone help me track down what is going on and suggest to me how to fix the problem.
I assume that SQL Server Management Studio optimizes the execution path somehow, but I'm not sure how to gain the same benefit for my passed query. Can I enable something with hints? Is there something else going on that I should know about?
I have a sql snippet from a 3rd party application that will not complete its transaction. The SELECT statement executes but does not finish. Instead the statement just sits in AWAITING COMMAND for 1000 seconds then dies, thus killing the UPDATE statement that is supposed to follow.
The CROSS JOIN and CROSS APPLY seem suspect.
(
@p0 DATETIME,
@p1 INT,
@p2 INT,
@p3 NVARCHAR(4000),
@p4 INT,
[code]....
I just ran into an issue with cascading locks due to a SPID on one of my production servers. When researching the lock, I noticed that there was no sql text. SP_Who 2, nor the following query captured anything,
SELECT sqltext.TEXT
, sqlplan.query_plan
, req.session_id
, req.status
, req.command
[Code] ....
I spoke to the user causing the lock and he ran into a visual basic error when this occurred and didn't close out that window. So my guess is that it's due to an uncommitted transaction. However, shouldn't I still see something if that was the case?
I have a query as follow:
SELECT @resRate = (SELECT resRate FROM ProjectAssign WHERE proNo = (SELECT projNo FROM Timer_Cust WHERE refNum = @actProjNo AND username= (SELECT username FROM Timer_Emp WHERE refNum = @actEmployee) ) )
the definition of table Timer_cust contains refNum(int), projNo(varchar) and projName(varchar).Timer_cust table doesn't contain column username. So this query shoud generate a runtime error. however it works fine without error.But if I run SELECT projNo FROM Timer_Cust WHERE refNum = @actProjNo AND username= (SELECT username FROM Timer_Emp WHERE refNum = @actEmployee)A runtime error message appears.Why?
hi there , i'm using sql server 2005 express and i have some problems with the two of my tables :), iwant to query both of my tables but the table entries are not in an equal count of rows for example:
incoming(table) outgoing(table)
money date corp money date corp
15 1,1,2006 ar 17 1,1,2006 ar
25 1,2,2007 ar 21 2,2,2007 es
35 2,2,2007 es
6 3,3,2007 ar
in this example the first table has more rows but the opposite is possible in my tables because this is an (account extract) query and here's my problem: first i used the "select incoming.money as m1,incoming date as d1,incoming.corp as c1,outgoing.money as m2,outgoing.date as d2,outgoing.corp as c2 from incoming left outer join outgoing on incoming.corp=outgoing.corp where incoming.corp='ar'(or don't use the where eliminating)" any way i couldn't get the correct results, then i used the (union all) select , the result was ok but the results form is not what i want here's the form i want and is it possible to query to tables to get this?
in this query i just wanted the elements with the corporation named 'ar' for example:
m1 m2 d1 d2 c1 c2
15 17 1,1,2006 1,1,2006 ar ar
25 null(or (0)) 1,2,2007
6 null(or (0)) 3,3,2007
is it possible to achieve this form(and may be any of the tables may have more rows than the other, it's not exact) , i am in a very difficult position :) and now i need your help , thanks anybody to think of helping me
When I try to execute the below query:
select * from jobmaster where status in ('Active') and materialtypecode in (1,2) and unit='IMPERIAL' and superusercode='S051000014' order by controllercode,jobname
through ADO I got the error message:
Invalid column name controllercode
When I execute the same above query in MS SQL Query Analyzer it is working.
Is there any workaround?

Hi...
Not sure what's wrong with the query or table, but I just can't get the result I want.
The column is varchar(35) and contains toll free no, like 18001234567...
But when I queried using the query below, I can't get any results. Same if I use 1*, 18*, 180*...
SELECT ... FROM ...
WHERE CONTAINS(toll_no, '"1800*"')
However, if I used 18001* I do get results.
Can anybody show me how to get result for these cases?
Thanks.
Hi Friends,
I need a very strange SQL query.
I have table structure like
cat_id, cat_name, cat_parent_id
Each cat has subcategories and those subcategories can have subcategories means
1, Cat1, 0
2, Cat2, 0
3, Cat3, 2
4, Cat4, 2
5, Cat5, 4
So Cat1 >> Cat2 >> Cat3
Now , I need a list of cat, subcat and subcat's subcat in a single query. e.g.
If I need all subcat of cat 2 then
result should be
2,3,4,5
Is it possible in a single query?
thanks.
Good Morning!
First off, let me get my disclaimer out of the way - I'm a relative newbie at this SQL lark, so please ignore the kludgy-ness of this code etc. Thanks ;-)
Firstly, here's my query:
Code:
SET DATEFORMAT DMY
declare @issuecounter int; -- Declare
declare @previssue int; -- Declare
declare @date smalldatetime -- Declare
DECLARE @issues TABLE (issues int, dates smalldatetime)
-- Declare
DECLARE issue Cursor scroll FOR -- Create the cursor
select articleIssue, articleDate from cr_newsletterArticles
where newsletter = @newsletter -- Which Newsletter
order by articleIssue desc ;
open issue -- Open the cursor
SET @previssue = 0 -- Set our comparison variable to 0
FETCH next FROM issue -- Grab the first recordset from the cursor
into @issuecounter, @date -- Stick it into our variable
WHILE @@fetch_status = 0 -- While we're not at EOF
begin -- begin
if @issuecounter != @previssue BEGIN -- begin
insert into @issues(issues,dates)
values(@issuecounter, @date)
SET @previssue = @issuecounter -- set comparison variable to issuecounter
END
fetch next from issue -- Grab the next recordset
into @issuecounter, @date
END -- End
CLOSE issue -- close cursor
deallocate issue
select * from @issues
GO
When I run this query in Query Analyser, it seems to work fine. IE. I get a table returned with the correct values. However, when I try and get this data into ASP via the old objRS.open "EXECUTE stored procedure <value>" command, no data is returned...
I'm not sure if this is an ASP problem, or a SQL problem... So, I altered the query slightly, and instead of a temporary table, I used a static one in the database, and it still didn't work - even though when I open the table in Enterprise manager the content is there...
Also, if I run the query via an ASP objCommand.execute "procedure <value> " and then use objRS.open "SELECT * from table" then it pulls the data in properly then...
If I was dealing with millions of recordsets in my original table, then I can understand that maybe the ASP isn't waiting long enough for SQL to return its final table. But I'm currently only dealing with about 50... I'd rather use the temporary table route rather than static incase of multiple hits at the procedure at the same time...
Any ideas? Please go easy - I refer you back to my disclaimer ;-)
Thanks...

Hi all,Using SQL Server 2000, SP4.I have a table of street names (Rua) whose ids (cod_rua) are foreignkeys into a consumer table (Consumidor). It turns out that the "Rua"table has many unused records which I'd like to wipe out. For instance,there are some 2800 unused records in the "Rua" table, and only some200 records actually being used by the "Consumidor" table (which,itself, has some 5000 records).Attempting to find the unused records, I issued the following query:a)SELECT COD_RUA FROM RUAWHERE COD_RUA NOT IN (SELECT COD_RUA FROM CONSUMIDOR)To my surprise, the query came out empty. But the following queryshowed the 200 or so records which *are* being used:b)SELECT COD_RUA FROM RUAWHERE COD_RUA IN (SELECT COD_RUA FROM CONSUMIDOR)I've found two solutions for the query to list the records *notexisting* in the Consumidor table:c)SELECT COD_RUA FROM RUAWHERE COD_RUA NOT IN (SELECT COD_RUA FROM CONSUMIDORWHERE COD_RUA IS NOT NULL)d)SELECT COD_RUA FROM RUAWHERE COD_RUA NOT IN (SELECT COD_RUA FROM RUAWHERE COD_RUA IN (SELECT COD_RUA FROM CONSUMIDOR))I know that there are many other possible solutions to the query(including left joins), but what I don't understand is why the query a)failed.Can some of you, oh mighty gurus, enlighten me?For the record, here's how both tables are (partially) declared:CREATE TABLE Rua (Cod_Rua int NOT NULL ,Rua varchar (35) NULL ,-- ...-- other unrelated fields-- ...CONSTRAINT Pk_CodRuaPRIMARY KEY (Cod_Rua))CREATE TABLE Consumidor (Cod_Consumidor int NOT NULL ,Cod_Rua int NULL ,-- ...-- other unrelated fields-- ...CONSTRAINT Pk_CodConsumidorPRIMARY KEY(Cod_Consumidor) ,CONSTRAINT Fk_CodRua_ConsumidorFOREIGN KEY (Cod_Rua)REFERENCES Rua (Cod_Rua))Regards,Branco Medeiros

the big table. We've also created a filegroup for the nonclustered
indexes from those big tables.
2. The Server is running SQL Server 2000 with SP3a
3. We've reindexed the database, updated statistics on all tables
Now, we have a SP that on the old configuration took about 20 min to complete.
But now, on our new configuration with the modifications listed above it's taking about
3 HOURS.
This is the SP's body: is calling a function:
create proc X
as
begin
Select dbo.myfunc(mytable.field)
from mytable
end
The function used in select statement is querying those 2 huge tables.
If the select statement is runned for only one record it's done instantly, but for 20000 recs it is taking almost 3 hours.
I must specify that also the function is running instantly, but in that select statement something is happening and we don't know what!!!
If you have any ideeas on what to do or what to check
Thanks a lot

Hi,
I am seeming strange results with a query. I have two tables, lets call them Table1 and Table2. Table1 has an ID field, Table2 does not have an ID field. To be sure I wasn't blind, the query
'SELECT ID FROM Table2'
returns: Invalid column name 'ID'. OK. Now when I run the query
'SELECT * FROM Table1 WHERE ID IN (SELECT ID FROM Table2)'
it returns all the records from Table1.
What gives? Is this a bug, or am I missing something?
Jezemine,
No, the number of reads is approximately the same. I can also confirm the disk read speed is the same on the test vs. production server. Update stats is run regularly on the production server - as I test, I ran sp_updatestats and then immediately ran the query a few times but it didn't affect the duration. Apart from the durations in the profiler traces, I can't see any differences. Clearly, something is causing the increased duration on the prod server but I don't know where to look to find it. It's definitely within SQL Server 2000.

Hello All,
I have been trying to get this code work, but I could not. Every thing seems going well. However, The result of running the sql query is strange. It shows the field names twice.
Eg:) if you have a table called "newtable" that has two fields[Custnumber, Custname], you will get somthing like this [Custnumber, Custname Custnumber, Custname]. I have tried many times, but I couldn't fix it.
Sub Page_Load(sender As Object, e As EventArgs) handles Mybase.Load
if not page.Ispostback then
try
Sqlconnection = New Sqlconnection (connectionString)
querystring = "SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNs
WHERE TABLE_NAME = 'Newtable'"
SqlCommand = New SqlCommand(queryString, Sqlconnection)
SqlConnection.Open
dataReader = SqlCommand.ExecuteReader(CommandBehavior.CloseConnection)
while dataReader.Read()
Tablefields_txt.text += dataReader.Getstring(0) & ", "
End while
catch ex as Exception
msgbox("An error has occured: " + ex.Message,0, "Error Message")
finally
SqlConnection.Close()
End try
End if
Any help , please
We have SQL server 7 installed. And we experiencing the performance problem.
When I tried to solve this problem I have found the interesting thing:
We have the table S_EVT_ACT with the non clustered index
S_EVT_ACT_F4 created on [OWNER_PER_ID], [APPT_REPT_FLG] fields and another clustered one
S_EVT_ACT_M4 created on [ROW_STATUS], [OWNER_PER_ID] fields
I use the next select statement and before run this statement I declare the variable @P1 - @P5 and set the values to them:
declare @P1 as char(1)
declare @P2 as char(1)
declare @P3 as char(1)
declare @P4 as varchar(10)
declare @P5 as char(1)
set @P1 = 'Y'
set @P2 = 'Y'
set @P3 = 'N'
set @P4 = '1-K56'
set @P5 = 'Y'
SELECT
..
...
...
FROM
dbo.S_EVT_ACT T1 --(index = S_EVT_ACT_F4)
LEFT OUTER JOIN dbo.S_CONTACT T2 ON T1.TARGET_PER_ID = T2.ROW_ID
LEFT OUTER JOIN dbo.S_OPTY T3 ON T1.OPTY_ID = T3.ROW_ID
LEFT OUTER JOIN dbo.S_ORG_EXT T4 ON T1.TARGET_OU_ID = T4.ROW_ID
LEFT OUTER JOIN dbo.S_EVT_ACT_X T5 ON T1.ROW_ID = T5.PAR_ROW_ID
WHERE
((T1.ALARM_FLAG = @P1 OR T1.APPT_REPT_REPL_CD IS NOT NULL) AND
(T1.APPT_REPT_FLG = @P2 AND (T1.CAL_DISP_FLG = @P3 OR T1.CAL_DISP_FLG IS NULL)) AND
(T1.OWNER_PER_ID = @P4) AND
(T1.TEMPLATE_FLG != @P5 OR T1.TEMPLATE_FLG IS NULL))
ORDER BY
T1.CREATED
In this case Query Analyzer uses S_EVT_ACT_M4 index and the performance is bad!
But when I try to run the same statement and use hard code 'Y' instead of the variable @P2 the Query Analyzer uses the S_EVT_ACT_F4 index and performance is PERFECT.
Question: What the difference between using variable @P2 and hard code 'Y' in the select statement and how to configure SQL server to use the right index in the situation when I can't change the Select statement and use the hard coding?
Any Idea will be very Appreciated.

I am trying to make a single display page for an author's books.the books page only displays books of a type "type" (novels, non-fiction, etc)I would like to make it so that it can also show all books if "type" isn't selected. I THOUGHT the string would look like this: <asp:SqlDataSource ID="SqlDSBooks" runat="server" ConnectionString="<%$ ConnectionStrings:csK2Reader %>"
SelectCommand="SELECT * FROM [Books] ( If @Type <> "" then WHERE ([Type] = @Type)) ORDER BY [SortDate] DESC"> But it doesn't seem to want to work. I get a "server tag is not well formed" error.
I have a table called "member" that has two fields (amongst others) called "firstname" and "city"I want to return a list that sorts people who live in the same city, but does not return people who do not have a city in common.For example if this is my data:Karen - ParisMike - RomeTim - Dallas
Jim - ParisChris - DallasJohn - ManhattanSarah - OrlandoDavid - DallasThe query would return this:Dallas - ChrisDallas - DavidDallas - TimParis - JimParis - KarenI have this SQL so far: Select city, firstname From member Order By city, firstnamebut it includes all the cities including those that only have 1 resident.Can someone tell me how to do this?Thanks a lot,Chris

Many thanks

I am trying to select players from a database based on the userid not having any user's name in it with an order by ASC. I basically want all the players that haven't been taken. Here is what I came up with and it gives me empty.
strSQLA="SELECT UserID, playerName from Allplayers WHERE UserID = '' ORDER BY playername ASC"
I hope it's considered appropriate to post a SQL query question here; it's not I'll gladly post this question elsewhere. That having been said, I've run into a simple but quite tricky SQL query and was wondering if the community might be able to help. Here's what's going on:
I have a "Documents" table. Let's call it DI have a "Benefits" table. Let's call it B.There is a many-to-many relationship between D and B so I have a third table to store the relationships. Let's call that table BD.
When I create a document it creates a row in D. Let's call that D1, D2...DN. When I create a benefit it creates a row in B. Let's call that B1, B2...BN
When I associate a document to a paritcular benefit, let's say that if D1 and B2 are associated, that I created row B2-D1 in my BD table. Now here's what my challenge is. Suppose I have these entries in my tables:
D: D1, D2, D3B: B1, B2, B3
Table BD:B1-D1B2-D1B2-D2
When the user goes to add documents to benefit B1, I want to show the user only documents that are not yet added to B1. In this case, I want to show the user D2 and D3 but not D1 since that one's already added. How do I write a SQL query to do this?
Here's what I've been using, but it shows too many results (e.g. included D1, D2, D3)
SELECT D.*, BD.*FROM Documents AS d LEFT JOIN rel_BenefitsDocuments AS bd ON d.doc_id = bd.doc_idWHERE (benefit_id <> @benefit_id OR benefit_id IS NULL)
Any thoughts?
Hi,
I want to write a sql query for an asp page which will display only unique rows from the specified column along with the number of count for each unique row.
Example:
Table that I want to query
Last Name || First Name
Gates || Bill
Boyce || Mike
Gates || Bill
Gates || Phil
Results I want:
Last Name || First Name || Count
Gates || Bill || 2
Boyce || Mike || 1
Gates || Phil || 1
Thanks a lot,

Hi,
I have a very simple question:
declare @treshold int
set @treshold = 10
SELECT
dbo.fn_Calc(t.column1) as calc,
t.column2
FROM
mytable t
WHERE
dbo.fn_Calc(t.column1) > @treshold
I can't think of a way to get rid of the function call in the WHERE clause.
Is this actualy a problem ?
I mean does realy the function fn_Calc execute 2 times in this statement and isn't this a performance issue then?
thanks
