Populating An SqlDataSource Using A Session Variable
May 29, 2008
I'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?

I'm getting a type mismatch error (currently string, when I think I need Int32 ?) with the code below. I'm having difficultly setting my session variable to type Int32 and having it take up the value of RawCoDeptRowID. When I "Watch" it, it's value remains as "snCoDeptRowID". Also, not sure if my Update command and it's snCoDeptRowID input parameter is well formed? Any advice would be greatly appreciated. Thank you.
Web Page 1:
Session["snCoDeptRowID"] = Convert.ToInt32 (RawCoDeptRowID);
Web Page2:<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
UpdateCommand="UPDATE [CompanyDepartment] SET [User_Name] = @User_Name, [FirstName] = @FirstName, [LastName] = @LastName, [Company_Name] = @Company_Name, [Department_Name] = @Department_Name WHERE [User_ID] = @snCoDeptRowID ">
<updateparameters>
<asp:parameter Name="User_Name" Type="String" />
<asp:parameter Name="FirstName" Type="String" />
<asp:parameter Name="LastName" Type="String" />
<asp:Controlparameter Name="Company_Name" Type="String" ControlID ="ListBox1" PropertyName ="SelectedValue" />
<asp:Controlparameter Name="Department_Name" Type="String" ControlID ="ListBox2" PropertyName ="SelectedValue" />
<asp:QueryStringParameter Name="User_ID" Type="Int32" QueryStringField ="@snCoDeptRowID" DefaultValue ="@snCoDeptRowID" />
</updateparameters>
</asp:SqlDataSource>

Hi,
I got a page with 3 sqldatasources and 2 dropdownlists and 1 gridview.
2 sqldatasources may load when the page load adn fill in the 2 DDL's.
But 1 sqldatasource and the gridview may only be loaded when I press a button. This is because otherwise every time I load the page more then 5000 records. (the 2 DDL's are filters for the 3th sqldatasource)
Anyone an idea how to solve this problem?
Best regards,
Karel

Hi Everyone,
I set the session("MyTable") with the user's name as contents when the user logs in, then I copy a new table name with session("MyTable") , I set PK and this all works, but I can't seem to figure out how to use the session var as table name SQLDataSource Selectcommand? I try a bunch of different stuff, putting it into a key in the web.config. Seems like this should be a piece of cake.
Im getting ~ "Session variable is not a valid datasource item" etc. Below is one of the things I have tried.<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Connectio String %>" SelectCommand="Select * From [" + Session("MyTable") + "] Where ID = @ID">
TIA

I have a sql data source that runs a query that returns a users data (See below). I want to set the session variable "UserID" equal to the tkinit. How do I "bind" the session to a column from this select command? I tried this Session("UserID") = ("tkinit") but that doesn't work. I can hard code a session value, just can't figure out how to "bind" it from the sqldatasource..
<asp:SqlDataSource ID="getUserID" runat="server" ConnectionString="<%$ ConnectionStrings:xxxConnectionString %>" SelectCommand="SELECT [tkinit], [tklast], [tkfirst], [tkfirst]+' '+[tklast] as fullname FROM [yyy] WHERE ([login] = @login)"><SelectParameters><asp:Parameter Name="login" Type="String" /></SelectParameters></asp:SqlDataSource>

I'm having trouble using session data in my select parameters. 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. I know the session data is set because I print the value at the top of the page, but for some reason it's not getting passed to the sessionparameter???
This is the datasource code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:flautoconnstr %>"
SelectCommand="SELECT * FROM [tblVehicles] WHERE ([profileid] = @profileid)">
<SelectParameters>
<asp:SessionParameter Name="profileid" SessionField="profileid" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
This is the line I use to set the session data.
Session["profileid"] = myQuote.Profileid;

Following is an example of a query which I use in a SP.
<BR><BR>
What I would really like to do is set both variables with one query. Can I get both data elements with one query, or do I have to run 2 queries to set 2 variables? This query is going to run over 2 servers and would like to save the extra trip.
<BR><BR>
set @int_MCID = (select top 1 iPID from customers inner join tblPersonnel on MtgConsultant = iPid where phone1 = @str_Phone and Position = 'Consultant')
<BR><BR>
set @int_LocID = (select top 1 iLocID from customers inner join tblPersonnel on MtgConsultant = iPid where phone1 = @str_Phone and Position = 'Consultant')
<BR><BR>
Select @int_LocID, @int_MCID

Please help!
I am designing an SSIS package and need to change the value of a DateTime global variable with the value returned from an Execute SQL task. The queary is as follows:
Select Versiondate = dateadd(dd,+1,Max(CreateDate)) from msdb..sysdtspackages p with(nolock)
where name = '@name'
The error message is as follows:
SSIS package "Package.dtsx" starting.
Error: 0xC002F210 at VersionDate_Set, Execute SQL Task: Executing the query "Select Versiondate = dateadd(dd,+1,Max(CreateDate)) from msdb..sysdtspackages p with(nolock)
where name = '@name'" failed with the following error: "The type of the value being assigned to variable "User::VersionDate" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: VersionDate_Set
SSIS package "Package.dtsx" finished: Success.
The variable is set to data type DateTime, but the value will not change. Any ideas?

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.

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?

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.

Hi, I'm trying to update a sqlserver database through vb.net in an asp.net 2.0 project. I'm using a sqldatasource and am trying to code an update parameter with a session variable.
code snippet: <UpdateParameters><asp:Parameter Name="hrs_credited" />
<asp:Parameter Name="updater_id" DefaultValue="<%$ Session("User_ID")%>" Type="Int32"/>
<asp:Parameter Name="activity_id" />
<asp:Parameter Name="attendee_id" /></UpdateParameters>
The error message that I receive is:
Error 2 Literal content ('<asp:Parameter Name="updater_id" DefaultValue="" Type="Int32"/>') is not allowed within a 'System.Web.UI.WebControls.ParameterCollection'. C:DevelopmentCMEdataentryattendance.aspx 29
Does anyone have an idea how to assign the session var value to the parameter?
Thanks!

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

I am using a SqlDataSource in my form page to query the DB and populate a GridView. If for example the value of Cell (3) is "1" I want to display the values of two other fields, Cells (6) & (7) in two ASP BoundFields 4 and 5.
Then, When Cell(3) = "2" I want to compare two Cells (8) & (9) procede as above, placing those values in ASP BoundFields 4 and 5.
Ive tried using the code below to do the comparisons of all the fields that I am using and then not displaying them with "Visible=False" as I dont want all the fields to be visible... But this method has become quite cumbersome to manage.
Is there a better way to do this??
Thanks!
Protected Sub TestStatus_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then If e.Row.Cells(3).Text = 1 Then
e.Row.Cells(4).Text = "<font color=Green><b>" & e.Row.Cells(6).Text & "</b></font>" e.Row.Cells(5).Text = "<font color=Red><b>" & e.Row.Cells(7).Text & "</b></font>"
e.Row.Cells(6).Visible = False e.Row.Cells(7).Visible = False e.Row.Cells(8).Visible = False e.Row.Cells(9).Visible = False
End If
If e.Row.Cells(3).Text = 2 Then
e.Row.Cells(4).Text = "<font color=Orange><b>" & e.Row.Cells(8).Text & "</b></font>" e.Row.Cells(5).Text = "<font color=Blue><b>" & e.Row.Cells(9).Text & "</b></font>"
e.Row.Cells(6).Visible = False e.Row.Cells(7).Visible = False e.Row.Cells(8).Visible = False e.Row.Cells(9).Visible = False

Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

I have been using a workaround because i think I don't understand something about sqldatasource select parameters.
I am using control parameters as a workaround for when i want to use a variable at runtime. i assign the value to the control - then use that as my select parameter. is there another way?
here's what i do:
<asp:Literal runat="server" ID="litCurrentYear" Text="" Visible="False"></asp:Literal>
<asp:SqlDataSource runat="server" ID="dsSummaryTable" ConnectionString="***"SelectCommand="spReportSummary" SelectCommandType="StoredProcedure"><SelectParameters><asp:ControlParameter Name="CurrentYear" ControlID="litCurrentYear" PropertyName="Text" /></SelectParameters></asp:SqlDataSource>
On PageLoad I assign litCurrentYear.Text whatever value I want. It works fine. But there must be a more elegant way - I just don't know it yet :)

First I want to say thanks to the folks how have helped me over the past week or two.
I'm missing a crucial piece of insight. How do I read a single piece of data from a SqlDataSource which only hold one row of data into a declared variable?
string zUserName = SqlDataSource.(get the value in the row that is labeled UserName)
It really doesn't matter to me whether it is an SqlDataSource or some other data container that hold the data I've selected. My goal is to be able to read some data from some predefined datasource into a declared variable.
If I am approaching this problem in the wrong way any advice or article links you could give me would be grealy appreciate.
Thanks, Bill

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.
