I'm having some serious performance issues with one of my reports due to the volume of records. The report is based on a stored procedure and passes date range and a few other parameters to it, but because I want the user to be able to select multiple physicians for this report, I am reading the data from the stored procedure and THEN filtering for physicians. I would like to change the stored procedure so that it accepts the parameter from crystal with multiple values and breaks it into separate values in an IN statement. Anyone ever done that?
