I am trying to figure out a way to retrieve a field value and assign it to a local variable with out destroying the whole structure of my T-SQL statement.
Here is the code:
DECLARE @AVERAGE_WHOLESALE_PRICE VARCHAR(20)
DECLARE @ORDERBY VARCHAR(20)
SELECT TOP 1 @AVERAGE_WHOLESALE_PRICE = P.NPT_PRICEX,
CASE NPT_TYPE
WHEN '07' THEN 1
WHEN '09' THEN 2
[Code] ....
The error message is
Msg 141, Level 15, State 1, Line 3
A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations.
How to modify this statement?

Hello, I'm needing to pass a variable length number of values to a select statement so I can populate a result list with items related to all the checkboxlist items that were selected by the user. for example, the user checks products x, y and z, then hits submit, and then they see a list of all the tests they need to run for each product. I found a UDF that parses a comma delimited string and puts the values into a table. I learned how to do this here: http://codebetter.com/blogs/darrell.norton/archive/2003/07/01/361.aspx I have a checkboxlist that I'm generating the string from, so the string could look like this: "1,3,4,5,7" etc.I added the function mentioned in the URL above to my database, and if I understand right, I should be able to pass the table it creates into the select statement like so:
WHERE (OrderStatus IN ((select value from dbo.fn_Split(@StatusList,','))) OR @StatusList IS NULL) but now I don't know how to assign the string value to the parameter, say to '@solution_id'.my current select statement which was generated by Visual Studio 2005 looks like this: SELECT [test], [owner], [date] FROM [test_table] WHERE ([solution_ID] = @solution_ID) ...but this only pulls results for the first item checked in the checkboxlist.Does anyone know how this is done? I'm sure it's simple, but I'm new to ASP .NET so any help would be greatly appreciated.

I have multiple SqlDataSources on a page. I only want them to execute the select query when the user performs a certain action. Is this possible? Or do they all execute as soon as the page is loaded?

Hello all,
I have been working with a DetailsView control for the past week and it is a great control, but also lacks on some departments. Anyhow I need to know what the best approach for this scenerio would be?
I have a SqlDataSource"
<asp:SqlDataSource ID="SqlUpsertAffiliateDetails" runat="server" ConnectionString="<%$ ConnectionStrings:connectionstring %>"
SelectCommand="SELECT am.affiliate_id AS AffiliateId, am.member_id AS MemberId, m.First_Name, m.Last_Name, am.category_id AS CategoryId, ac.category_name, am.profile_web_address AS WebAddress, am.profile_email_1 AS Email, am.comments AS Comments, am.date_modified FROM tAffiliateMaster AS am WITH (NOLOCK) INNER JOIN tAffiliateCategories AS ac WITH (NOLOCK) ON am.category_id = ac.category_id INNER JOIN rapdata..Member AS m WITH (NOLOCK) ON am.member_id = m.Member_Number WHERE (am.affiliate_id = @AffiliateId)"
UpdateCommand="spUpsertAffiliateProfile" UpdateCommandType="StoredProcedure">
<SelectParameters>
<asp:QueryStringParameter Name="AffiliateId" QueryStringField="affiliate_id" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="Action" Type="Byte" DefaultValue="2" />
</UpdateParameters>
</asp:SqlDataSource>
And my SP:/* 09-19-07 Used to update affiliate profile */
CREATE PROCEDURE spUpsertAffiliateProfile
@Action tinyint,
@AffiliateId int,
@MemberId int = -1,
@CategoryId int,
@WebAddress varchar(50),
@Email varchar(50),
@Comments varchar(1500)
AS
SET NOCOUNT ON
-- Find errors first, check is not needed if deleting
IF @Action <> 3
IF NOT EXISTS (SELECT Member_Number FROM rapdata..Member_Association WHERE Member_Number = @MemberId AND Status = 'A' AND Association_ID = 'TRI' AND Bill_Type_Code LIKE '%AF%')
BEGIN
SELECT retval = 'A qualified member ID was NOT found. Action Failed.', errorcount = 1, 0 AS affiliate_id
RETURN
END
IF @Action = 1
IF EXISTS (SELECT member_id FROM tAffiliateMaster WHERE member_id = @MemberId)
BEGIN
SELECT retval = 'This member has already been listed. Action Failed.', errorcount = 1, 0 AS affiliate_id
RETURN
END
IF @Action = 1 AND @AffiliateId = 0-- insert
BEGIN
INSERT INTO tAffiliateMaster
(member_id, category_id, profile_web_address, profile_email_1, comments)
VALUES
(@MemberId, @CategoryId, @WebAddress, @Email, @Comments)
SELECT retval = 'Record Entered', errorcount = 0, @@IDENTITY AS affiliate_id
RETURN
END
ELSE IF @Action = 2 AND @AffiliateId > 0-- update
BEGIN
UPDATE
tAffiliateMaster
SET
category_id= @CategoryId,
profile_web_address=@WebAddress,
profile_email_1=@Email,
comments=@Comments
WHERE
affiliate_id = @AffiliateId AND member_id = @MemberId
SELECT retval = 'Record Updated', errorcount = 0, @AffiliateId AS affiliate_id
RETURN
END
ELSE IF @Action = 3 AND @AffiliateId > 0-- delete
BEGIN
DELETE
tAffiliateMaster
WHERE
affiliate_id = @AffiliateId
SELECT retval = 'Record Deleted', errorcount = 0, 0 AS affiliate_id
RETURN
END
GO
My question is how will I be able to return the retval? Will I need to do it within the code behind of the SqlDataSource Updated Event?
Thanks!

I have 3 web identical web apps whose only diff is that they access different SQl Server DB's. I use the SQLDataSource in a number of pages to retrieve data from the db. The apps all use Forms Auth. I would like to be able to see who is the logged on user user and assign the approp connection string to all the SQLDataSources in the app. For example when user UserA logs in they are retrieving data from on db but when UserB logs in they are retrieving data from another db.
I am sure this can be done but could use a little guidance. Thanks in advance.

Hi you all,
In abc.aspx, I use a GridView and a SqlDataSource with a SelectCommand. The GridView's DataSourceID is the SqlDataSource.
In abc.aspx.cs, I would like to use an IF statement in which if a criterion is not satistied then I will use the SqlDataSource with another SelectCommand string. Unfortunately, I have yet to know how to write code lines in order to do that with the SqlDataSource. Plz help me out!

Is there a way to retreive the SQL Statement with the values from the parameters merged together? I know how to retreive the SQL Select Statement and the parameters separately but I need to retreive the final SQL.
For example:
SELECT name FROM employee WHERE id = @id
I would like to retreive from SQLDataSource
SELECT name FROM employee WHERE id = 1
Thank you

Hello,
I am not sure if this possible, but I have store procedures that access to multiple databases, therefore I currently have to hardcode my database name in the queries. The problem start when I move my store procedures into the production, and the database name in production is different. I have to go through all my store procedures and rename the DBname. I am just wonder if there is way that I could define my database name as a global variable and then use that variable as my DB name instead of hardcode them?
something like
Declare @MyDatabaseName varchar(30)
set @MyDatabaseName = "MyDB"
SELECT * from MyDatabaseName.dbo.MyTable
Any suggestion? Please.
Thanks in advance

I have several Sql Tables, each containing more than 100 fields, on which I need to perform display operation through GridView, Insert and Update through an array of dynamically created and databound TextBoxes.
I would like to use a single page to manage all Sql Tables on the basis of the name of the specific one invoked by the user.
In order to achieve that, I need to dynamically configure the SqlDataSource Web Control present on the page for each Sql Table. In particular I need to generate at runtime the InsertCommand and the UpdateCommand.
On how to do it I have no idea.

CancelSelectOnNullParameterHi,Suppose I have a SQLDataSource with a
SelectCommand="SELECT * FROM STOCKS WHERE USER=@USER ORDER BY STOCK_NAME"
and @USER is set as a session parameter. No problem till this part, but in some postbacks, I wish to add a new WHERE criteria to my SQL, so I do:DSSQL.SelectParameters.Add("@STOCK_NAME", "ABC123");
DSSQL.SelectCommand = DSgvStoklar.SelectCommand.Replace(" ORDER BY ", " AND STOCK_NAME LIKE @STOCK_NAME+'%' ORDER BY ");
gridViewDS.DataBind();
and wish that my SelectCommand is modified and a new parameter is added.
The SQL is modified, however -I guess- new parameter is not added, so I get "Must declare the scalar variable "@STOCK_NAME" error.
How can I solve, any ideas?

Hi
I want to use a variable in a number of SQL statements as paramenter. But I am not sure how to assign the value I want to the variable. The value I want is the maximum week number from one of my tables. I know how to put this value into a new table (which is one field and One row), but I cannot see how to pass this value to my variable. Using the table in my SQL is not straight forward unfortunately, at least not for me.

Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)
For example,
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.
Appreciatively,Peter

What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.

Hi all
I have a cms-page where i want to display various entry-categories like news etc....I want to define which kind of entries should be shown by a parameter in the URL (e.g. cms.aspx?category=news). So far everything is OK.
To display the entries actually I'm using the following SqlDataSource:
<asp:SqlDataSource ID="SqlDataSourceCMS" runat="server" ConnectionString="......."SelectCommand="SELECT * FROM [cms] where category = news"></asp:SqlDataSource>
What i need, is to set the category which i want to show dinamically, like with a variable.
Does anybody know how i can set something like a variable in the SelectCommand property of the SqlDataSource?

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">
<UpdateParameters>
<asp:ControlParameter Name="USERNAME" ControlId="txtUserName" PropertyName="Text"/>
<asp:ControlParameter Name="SERVICE_TAG" ControlId="txtServiceTag" PropertyName="Text"/>
<asp:ControlParameter Name="TECH" ControlId="txtTech" PropertyName="Text"/>
<asp:ControlParameter Name="DESKTOP" ControlId="txtComputerName" PropertyName="Text"/>
</UpdateParameters>

Hi this is probably a very stupid question, but I still need to know.
How do I set the result of a 'SELECT' statement to a variable? I know I can use CURSOR, but I am certain the SELECT statement will return either 1 record or NULL. Can I use something else apart from CURSOR?

Hello,
This is my foray into Stored procedures, so I'm hoping this is a fairly basic question.
I'm writing a stored procedure, in which I dynamically create an SQL statement.
At the end of this, the SQL statement reads like:
Code SnippetSELECT COUNT(*) FROM StockLedger WHERE StockCode = 'STOCK1' AND IsOpen = 1 AND SizeCode = 'L' AND ColourCode = 'RED' AND LocationCode IS NULL AND RemainingQty > 0
Now this statement works a charm, and returns a single value. I want to assign this count to a variable, and use it further on in the stored procedure. This is where the problems start - I cant seem to do it.
If I hard code a statement, like
Code SnippetSELECT @LineCount = COUNT(*) FROM StockLedger
that works fine (although it brings back a count of all the lines).
But if I modify the dynamically created SQL Statement from earlier on to:
Code SnippetSELECT @LineCount = COUNT(*) FROM StockLedger WHERE StockCode = 'STOCK1' AND IsOpen = 1 AND SizeCode = 'L' AND ColourCode = 'RED' AND LocationCode IS NULL AND RemainingQty > 0
it doesnt work - it complains: Must declare the scalar variable "@LineCount".
Just to clarify, when I say "dynamically created an SQL statement, I mean that by a bunch of conditional statements I populate a varchar variable with the statement, and then eventually run it exec(@SQLStatementString)
So, my question would be, how do I do this? How do I make a dynamically generated SQL statement return a value to a variable?

Hey all. I'm trying to create a stored proc that will update a variable column, depending on the parameter I pass it. Here's the stored proc:
CREATE PROCEDURE VoteStoredProc
(
@PlayerID int,
@VoteID int,
@BootNumber nvarchar(50)
)
AS
DECLARE @SQLStatement varchar(255)
SET @SQLStatement = 'UPDATE myTable SET '+ @BootNumber+'='+ @VoteID + ' WHERE (PlayerID = '+ @PlayerID +')'
EXEC(@SQLStatement)
GO
I get the following error:
Syntax error converting the nvarchar value 'UPDATE myTable SET Boot3=' to a column of data type int
The update statement is good, because if I use the stored proc below (hard-coded the column), it works fine.
CREATE PROCEDURE VoteStoredProc
(
@PlayerID int,
@VoteID int,
@BootNumber nvarchar(50)
)
AS
UPDATE
myTable
SET
Boot3 = @VoteID
WHERE
PlayerID = @PlayerID
GO
Is there a way to dynamically choose a column/field to select from? Or is my syntax incorrect..?
Thanks!
