but i m getting following error Msg 8114, Level 16, State 5, Procedure SP_Firstdistil, Line 0Error converting data type nvarchar to datetime. what i have done here is, i have called SP_Firstdistil procedure with parameter @sdate in SP_FinalYieldtemp in stored procedure. when i executed SP_Firstdistil procedure, it gave me proper output. i m very confused in SET @SQL statement in SP_FinalYieldtemp procedure.plz help to resolve it
