SSRS Date Range

Hello All,

I am having issue with the Date Range in the SSRS report. How do I pass the start date and end date parameters in the following query? I tried using(Transdate = @PrmStartDate AND TransDate=@PrmEndDate) in the query below but it does not work. Following is the SQL statement used in the Dataset. Please help me with this.

Thanks,

Amol
