and i have another stored procedure as follows

USE [cheminova] GO /****** Object:  StoredProcedure [dbo].[SP_FinalYieldtemp]    Script Date: 10/30/2014 10:22:51 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author:		<Author,,Name> -- Create date: <Create Date,,> -- Description:	<Description,,> -- ============================================= ALTER PROCEDURE [dbo].[SP_FinalYieldtemp]  	-- Add the parameters for the stored procedure here 	@sdate datetime 	 AS BEGIN 	-- SET NOCOUNT ON added to prevent extra result sets from 	-- interfering with SELECT statements.

and i execute SP_FinalYieldtemp as follows:

Collapse | Copy Code
exec SP_FinalYieldtemp '2014-10-29'

but i m getting following error

Msg 8114, Level 16, State 5, Procedure SP_Firstdistil, Line 0
Error 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
