I am developing a simple report containing a parameter.

Select Provider
From amProvider
Where (@Prov = '' or Provider = @Prov)

I want to give the user the option of selecting a value from a drop down list or leaving the parameter blank. The values in the dropdown list are obtained from another query.

Select Provider
From AmProvider
Where Provider Like 'A%'

The parameter is set to allow Blank values

However, The report won't run if no value is given for the parameter when the parameter list is generated from a query. If The parameter does not come from a query it pulls all Providers as it should.

Is it possible to leave a parameter that is generated froma a query blank and have the query run?

If so, Please let me know what I need to do to make it work.

Thanks....Franco

WHERE @Prov IS NULL OR Table.Field=@Prov works...should still run the query...what exactly is the problem?

If the parameter is left blank, the report simply does not process.
