如何使用根据参数返回数据的过程创建SSRS报告

Question

I have a stored procedure that returns number of columns based on parameter @SearchType. So first it checks what is the parameter value, then SELECT statement returns data.

My problem is how can I use this procedure in SSRS? It doesn't bring me any columns so I can add it to a table or matrix.

In SSMS the procedure works fine. There gotta be a work around for that.

Thanks

ALTER PROCEDURE dbo.RPT_spLoadUserOpenTasks
      (
        @UserGUID varchar(8000) = NULL,
        @NoteStoreType INT = NULL,
        @DateFrom datetime = NULL,
        @DateTo datetime =NULL,
        @LineGUID varchar(8000) = NULL
      )

 IF @SearchType = 0
 BEGIN 
       SELECT DISTINCT 
            TOP 100 PERCENT 
                Column1,
                Column2,
                Column3

             ORDER BY  Column1

if @SearchType = 3 --And so on

You have to define the columns of your query outputs manually in the dataset.

Since column names and number is not static try to do so by having each query to return the same number of columns having empty data for columns not required.

For each value of your parameter, create the table containing the required columns and set table visibility depending the selected value of the parameter (for example if parameter has 3 values you have to create 3 tables but only one will be visible each time).
