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.
In my program i have function that will get one value from Database.
Here i want to assign the output of the sql query to a local variable.
Its like select emp_id into Num from emp where emp_roll=222;
here NUM is local variable which was declared in my program.
Is it correct.?
can anyone please guide me..?

View 1 Replies View RelatedI 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?

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 All,

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

Wondering is there a different way in 2012 to pass values to variables dynamically.

Hello
Following is my code which is not working.
<asp:SqlDataSource ID=events runat=serverSelectCommand="SELECT * FROM TBL_EVENT WHERE SECTION_ID=<%= Session("ID")%>"ConnectionString = "<%$ appSettings:SQLConnectionString %>"</asp:SqlDataSource>
I want to pass the value of Session("ID") into that query. How can I do that?
Hi, how I do create SqlDataSource in the code-behind,setting Select SQL along with its parameters and, finally automically generating Del, Update, Insert SQL.
Is there a way to achieve this goal as it would in VS designer?
Thanks,
Ricky.
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.
Hi,
say I have two Sqldatasources objects:SqlDataSource1 and SqlDataSource2....
Does anybody know how can I alter programmatically these two sqldatasources in a gridview?
Thanks!!!
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"/>

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... im having a problem with my query optimization....
I have a query that looks like this:
SELECT * FROM table1
WHERE location_id IN (SELECT location_id from location_table WHERE account_id = 998)
it produces my desired data but it takes 3 minutes to run the query... is there any way to make this faster?... thank you so much...
I am having 2 tables one is staging temp and another is main import table.
In my staging table there are 3 column Col001,Id,Loaddate
in Col001 column data are present with '¯' delemeter.
I am having function which is used to load data from staging to import table using one function.
this function create a insert statement.
My Existing function
-- Description: To Split a Delimited field by a Delimiter
ALTER FUNCTION [dbo].[ufn_SplitFieldByDelimiter]
(
@fieldname varchar(max)
,@delimiter varchar(max)
,@delimiter_count int
[Code] ....
I am unable to get correct statement with above function.
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!
