  Cannot Send Parameter to Stored Procedure

  Nov 19, 2018 09:09 AM|munirah-malik1|LINK

  Hi All,

  I'm having one stored procedure.  Error display when I try to pass parameter from system.

  Must declare the scalar variable "@KT_KEIRO_NAME_VAR".

  Here is the stored procedure.

  ALTER PROCEDURE [dbo].[EXEC_DATETM_SP2X]
  @KT_KEIRO_NAME_VAR Nvarchar(MAX), @KT_GUN_NO_VAR Nvarchar(MAX)
  
  AS
  BEGIN
  	SET NOCOUNT ON;
  	DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
  	DECLARE @ColumnName NVARCHAR(MAX)
  
  SELECT @ColumnName= ISNULL(@ColumnName + ',','') 
         + QUOTENAME(EXEC_DATETMM)
  FROM (SELECT distinct([EXEC_DATETMM]) FROM [WAFERRPTDB].[dbo].[V_COMBINE_WLQTQFLQ]) AS EXEC_DATETMM
  
  
      set @DynamicPivotQuery='
  	Select [KT_HYOU_NAME],
  	[KT_KEIRO_NAME],
  	[KT_GUN_NO],
  	[TUKA_JUN],
  	[KT_CD],
  	[SG_KU_CD],
  	' + @ColumnName + '
  		from 
  	(
  		SELECT * FROM V_DATEBYWLQ
  		where KT_KEIRO_NAME=@KT_KEIRO_NAME_VAR
          AND KT_GUN_NO=@KT_GUN_NO_VAR
  	) s
      pivot (MAX (WORK_LOT_QTY) for 
      [EXEC_DATETMM] in ('+ @ColumnName +')) as AvgWidgetsPerDayPerEmp
  	'
  EXEC sp_executesql @DynamicPivotQuery
  END

  How I want to send the parameter to SP. Please help

  Hi,

  Dynamic SQL runs inside another "context" where those parameters are not know so you still have to explicitely pass those values :

  EXEC sp_executesql @DynamicPivotQuery,N'@KT_KEIRO_NAME_VAR NVARCHAR(max),@KT_GUN_NO_VAR NVARCHAR(max)',@KT_KEIRO_NAME_VAR,@KT_GUN_NO_VAR

  Just see the doc for sp_executesql at https://docs.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-executesql-transact-sql?view=sql-server-2017
