How To Assign A Value To A Parameter?

Nov 17, 2006

Hello everyone,

i have the parameter in my stored procedure that i am using as a sqldatasource.

Now in one of the events, i need to assign a value to the parameter. How can i do that?

Microsoft is changing the syntax so often, all solutions i found on this forum just don't work anymore, like:

SqlDataSource1.SelectParameters["@CompareInteger"].value= "1"

OR

SqlDataSource1.SelectParameters["@CompareInteger"].DefaultValue= "1"

I guess the SelectParameter - became 'ReadOnly'..But how to assign value to a parameter now?!?

Thanks for any help

Assign A Foreign Key As A Parameter

Oct 15, 2007

hi everybody
I have the following asp.net2.0 codeSelectCommand = "Select IDEmp, FirstName,MiddleName,LastName, Date,HoursNumber, Description
From Employee, WorkOnCategory , CatDesignItemReference
where IDEmp =IDEmplWork AND FirstName = @FirstName AND Category = @AnyCategory AND ">

<SelectParameters>
<asp:ControlParameter ControlID="txtEmployeeName" DefaultValue="" Name="FirstName" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="DropDownList1" DefaultValue="" Name="AnyCategory" PropertyName = "SelectedValue" Type="String" />
</SelectParameters>

</asp:SqlDataSource>

The problem is that the AnyCategory in my DropDownList1 refers to a key but unfortunalely my code understand it as string so it assigns
Category = @AnyCategory as if Category ='AnyCategory ' not as Category = AnyCategory
So what should I do
Thanks

parameter name: 0,
parameter size: -1

connectiontype: OleDB
sourcetype: direct input
statement ELECT columnx FROM table1 WHERE (columnID=

How Do I Assign A String To A Parameter I'm Passing To A Select Statement?

Oct 30, 2006

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.

Assign XML To Variable

Jul 12, 2006

How do I assign XmlDocument results to a variable (so that I can pass it to a sp)?

I know that the following code works....

It returns "<row UserId="1225" LastName="Evans" FirstName="Stephanie" MiddleInitial=...."), which is what I want. But when I try to assign it, I get an error "Incorrect syntax near 'XML'."

declare @strXml nvarchar(1000)

set @strXml = (select * from tblUsers where userId = 1225 for XML raw)

Assign Function To Table Var??

Sep 19, 2007

I keep getting a declare error on this:
DECLARE @SplitTable TABLE(Idx BIGINT IDENTITY(1,1), SplitData VARCHAR(20), Size INT)
SET @SplitTable = dbo.SplitToTable('|', '1|One|0:26:20|541|abc|xxx|6:26:33|21705')

All I want to do is assign the table that my function returns to a variable. Should be easy, but I tried the above and assigning with 'as':

select * from dbo.SplitToTable('|','1|One|0:26:20|541|abc|xxx|6:26:33|21705') as Split

that didn't work either.

Also tried:
DECLARE @SplitTable TABLE(Idx BIGINT IDENTITY(1,1), SplitData VARCHAR(20), Size INT)
select @SplitTable= from dbo.SplitToTable('|','1|One|0:26:20|541|abc|xxx|6:26:33|21705')

what am I missing?

Assign Configuration Package

Aug 15, 2007

There is a configuration file which is used to hold a connectionstring for the ssis packages.
Once the configuration file is created then is it necessary to go to each package and then package configuration to point the package to the configuration file?
It seems the packages do not automatically refer to the config file. Instead each time the config file is changed then all the packages have to be pointed to the config file one by one. i.e. going from Dev to live.
Am I right?
Thanks
