Hi,
I try to set a Session variable with the result of a SQL Selec statement. I tried the following, but it is not working.
Session("thisone") = SqlDataSource1.SelectCommand = "SELECT myfield FROM [mytable] WHERE ([username] = @username)"
@username is a value from a textbox. What I am doing wrong?
Thanks for your help, Chris
I'm sure this is a very simple piece of code, but I'm having trouble understanding how to do this.
First I have a database with three columns

Hi...
I'm developing a web app with VS 2005 Beta and I do not know how to include a seasson variable value into my code.
This is my code:
Function GetData() As System.Data.SqlClient.SqlDataReader
Dim sqlconn As System.Data.SqlClient.SqlConnection
Dim SqlCommand1 As System.Data.SqlClient.SqlCommand
Dim sqlRdr As System.Data.SqlClient.SqlDataReader
sqlconn = New SqlConnection("SERVER=SRVR;UID=USR;Password=PWD;DATABASE=MyDatabase")
sqlconn.Open()
SqlCommand1 = New SqlCommand("MyStrProc", sqlconn)
SqlCommand1.CommandTimeout = 1800
sqlRdr = SqlCommand1.ExecuteReader(CommandBehavior.CloseConnection)
Return sqlRdr
End Function
MyStrProc is:
CREATE PROCEDURE MyStrProc
@MyVar int
AS
IF @MyVar IS NOT NULL
BEGIN
.................
......t12.acct_nbr IN (@MyVar)
.....
END
GO
The variable @MyVar get its value from user log info in login page, and create a session variable.
My Question:
How and where to call seasson variable @MyVar, because now I'm getting this error:
Procedure 'MyStrProc' expects parameter '@MyVar', which was not supplied.
Any help will be great.
Tks
Can we use session variable in reporting services.. say go to report -> properties and create a VB function that get ans set session variable.. If yes, how. If not, any workaround?
View 2 Replies View RelatedI'm having a real problem populating my SqlDataSource and was wondering if anyone could help. I'm sure it's something simple
First off, I created a session variable on a previous page like so Dim NewSubscribeID As Integer = Convert.ToInt32(retSubcribeID.Value)
Session("SubcribeID") = NewSubscribeID
I now want to use this session variable on another page to populate a SqlDataSource like so <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionXX %>" SelectCommand="spXX" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:SessionParameter Name="SubscribeID" SessionField="SubscribeID" Type="Int32" DefaultValue="0" />
</SelectParameters>
</asp:SqlDataSource>
Here is the problem... Only the default value gets used.
I've tried putting the session variable into a label to test that it does actually exist lblTest.Text = Session("SubcribeID")
and it does...What am I doing wrong?
Each user who inserts a new SQL record from the FormView control needs to have their UserID in one of the fields of the record. I have the user ID stored in the Session("UserID") variable. I am having trouble finding the right way to get this done. I have tried using a hidden text box but I can't seem to assign the value. I have tried the Insert Parameters but that will not accept <%# Session("UserID") %> as a DefaultValue. Any ideas would be helpful. Thanks.

What C# code would capture the Scope_Identity value (CoDeptRowID) output by the code below? Do I even need to capture it or is it already available as a C# variable CoDeptRowID ? I can't seem to get my hands on it!

Hi,I am new to SQL. Please bear with me and allow me to ask a dumbquestion.I am debugging a stored procedure (written in Trans-SQL), and I foundthat the SQL analyzer that I use doesn't have a debugger. All I cando it is execute a block of code and see what is going on in aninteraction seesion of the SQL analyzer. I would need to declare somevariable to hold values of the previous query in the interactivesession.I understand that this can be easily done in a stored procedure viathe Declare command (e.g., Delcare @order_no int). Is similarfunctionality exists in an interaction session of the SQL analyzer?If so, what is the command. Please advise.Thank you very much for the help.Alex

If I manually plug a value into the selectcommand or create a hard coded value using a parameter it works, but if I try to use the session data the query pulls no results.

The 2.0 version of ASPSTATE is slightly different than the 1.1 version in that one table has one additional column and another table uses a different data type and size for the key. The 2.0 version also has a couple additional stored procedures.
We'd like to manage just one session state database if possible so we're trying to figure out if Microsoft supports using the new schema for 1.1 session state access (it seems to work, but our testing has been very light).
Is there any official support line on this? If not, can anyone comment on whether or not you'd expect it to work and why?
Thanks.
Hello,
I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.
I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.
This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.
So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?
Thanks in advance,
Andy

I'm relatively new to SQL, and I'm trying to write some procedure.. but this wasn't working.. :(
I tried to make several smaller tables from one big table based on some value of one of the column. Here's my procedure:
USE WAREHOUSE
DECLARE
@COUNTER NUMERIC,
@TBLTTL CHAR(11)
SELECT @COUNTER = 1
WHILE (@COUNTER <40)
BEGIN
SET @TBLTTL= 'Inventory' + CAST(@COUNTER AS char(2))
SELECT *
INTO @TBLTTL <== *error refers to this line*
FROM MAIN
WHERE invtype=@COUNTER
SELECT @COUNTER = @COUNTER +1
END
The error message that I got was:
Incorrect syntax near '@TBLTTL' (look at * above)
What should I do if I want to create a loop which would create (or later update) new smaller tables automatically? Any suggestions are welcomed.
Thx,
Ferdinand.
I believe this is quite elementary but here goes
can you run a query like
SELECT * from Table where Item IN @variable
where @ variable is a varchar containing a list of items in quotes,seperated by a comma
THANKS

Hi,
I am writing a sproc that has simple search functionality, basically if someone selects ALL, then the sql should be the following
IF(@grade = 'ALL')BEGIN SET @gradeChoice = '1,2,3,4,5' END
ELSE BEGIN SET @gradeChoice = @grade END
Then i have
SELECT * from table where grade IN @gradeChoice
It doesnt seem to work as normal. I thought it would work the same with a variable?
Thanks for any help

Hi,
I am trying to get the login name of a user, trim off some characters, which works fine, convert this to a string variable, which works fine and then use this variable in an sql select parameter.
I've tried countless things and am not sure why my variable @NewString is not working in the Select command. If I add a default value I know is present, it works, but it can't seem to pick up the variable value of NewString. It prints out as expected in the response.write statement, but I really need it to connect to the corresponding value in the database.
Any ideas are greatly appreciated-code below.
