我一直在寻找一种解决方案，以防止MS SQL在存储过程中使用print语句时生成警告，但没有成功。

我正在从ETL应用程序执行此过程，我需要退出存储过程而不会出现错误或警告。

FYI - ETL过程执行存储过程时不需要print语句。这些是在手动执行的时候。

我已尝试过SET ANSI WARNINGS OFF和Try / Catch，但我仍然在输出上收到警告。

这是存储过程：


CREATE PROCEDURE [dbo].[spBackupSomeTables]
AS
BEGIN TRY
    SET ANSI_WARNINGS OFF
    PRINT 'Copying SomeTable1 to Z_Backup_SomeTable1' +  CHAR(10)
    SET ANSI_WARNINGS ON
    TRUNCATE TABLE  Z_Backup_SomeTable1
    INSERT INTO   Z_Backup_SomeTable1
    SELECT *
    FROM   SomeTable1

    SET ANSI_WARNINGS OFF
    PRINT 'Copying SomeTable2 to Z_Backup_SomeTable2' +  CHAR(10)
    SET ANSI_WARNINGS ON
    TRUNCATE TABLE  Z_Backup_SomeTable2
    INSERT INTO   Z_Backup_SomeTable2
    SELECT *
    FROM   SomeTable2

    SET ANSI_WARNINGS OFF
    PRINT 'All Done' +  CHAR(10)
    SET ANSI_WARNINGS ON

END TRY
BEGIN CATCH

    DECLARE     
        @ErrorNumber   VARCHAR(1000),
        @ErrorSeverity   VARCHAR(1000),
        @ErrorState   VARCHAR(1000),
        @ErrorProcedure   VARCHAR(1000),
        @ErrorLine   VARCHAR(1000),
        @ErrorMessage   VARCHAR(1000)


    SET @ErrorNumber = (SELECT ERROR_NUMBER() AS ErrorNumber)
    SET @ErrorSeverity = (SELECT ERROR_SEVERITY() AS ErrorSeverity)
    SET @ErrorState = (SELECT ERROR_STATE() AS ErrorState)
    SET @ErrorProcedure = (SELECT ERROR_PROCEDURE() AS ErrorProcedure)
    SET @ErrorLine = (SELECT ERROR_LINE() AS ErrorLine)
    SET @ErrorMessage = (SELECT ERROR_MESSAGE() AS ErrorMessage)


    PRINT 'ErrorNumber: ' + @ErrorNumber + CHAR(10)
    PRINT 'ErrorSeverity: ' + @ErrorSeverity + CHAR(10)
    PRINT 'ErrorState: ' + @ErrorState + CHAR(10)
    PRINT 'ErrorProcedure: ' + @ErrorProcedure + CHAR(10)
    PRINT 'ErrorLine: ' + @ErrorLine + CHAR(10)
    PRINT 'ErrorMessage: ' + @ErrorMessage + CHAR(10)

END CATCH
GO

这是执行结果：

 Warnings: ---> 
   W (1): Copying SomeTable1 to Z_Backup_SomeTable1
   W (2): Copying SomeTable2 to Z_Backup_SomeTable2
   W (3): All Done

在评论中使用建议/链接，这是我提出的解决方案..


CREATE PROCEDURE [dbo].[spBackupSomeTables] @Debug tinyint =1
AS
BEGIN

     IF @Debug IS NULL
        SET @Debug = 1;    

     IF @Debug > 0 
        RAISERROR( 'Copying SomeTable1 to Z_Backup_SomeTable1', 0, 1 ) WITH NOWAIT
    TRUNCATE TABLE  Z_Backup_SomeTable1
    INSERT INTO   Z_Backup_SomeTable1
    SELECT *
    FROM   SomeTable1

    IF @Debug > 0 
        RAISERROR( 'Copying SomeTable2 to Z_Backup_SomeTable2', 0, 1 ) WITH NOWAIT
    TRUNCATE TABLE  Z_Backup_SomeTable2
    INSERT INTO   Z_Backup_SomeTable2
    SELECT *
    FROM   SomeTable2

    IF @Debug > 0 
        RAISERROR( 'All Done', 0, 1 ) WITH NOWAIT
END
GO

@Debug参数默认值为1，这样人们就不必担心传递任何参数以查看打印的状态消息。 ETL作业将简单地为该参数传递值0以禁止打印语句，从而允许作业完成而不会发出任何（错误）警告。
