Basic Reporting Problem

Hi

I am having a problem with reporting. I want to query SQL data using dataset using a query which looks lie this.

slect thisparam,thatparam from tablex where thisparam = @.thisparam

thisparam is a user prompt. When the user leaves prompt value to be empty and clicks on view report i want to display the data

select thisparam,thatparam from tablex

else use the above statement with the parameters.

Could someone help me with this. Should I user filters or expression.

Thanks

You can do this in your SQL statement:

select thisparam, thatparam

from tablex

where thisparam = @.thisparam or @.thisparam is null

If you want to treat the empty string and null as the same, then just add another or:

where thisparam = @.thisparam or @.thisparam is null or @.thisparam = ''

Thank you it worked. Can you tell me if there are any tutorials to start for reporting services please let me know .

Thanks
