我无法使用THROW SQL Server 2008 R2

Question

它说,SQL Server 2008 R2 Management Studio无法识别下面的例子

Throw附近的语法错误

我试图在这里抛出一个错误,所以当有人插入两次相同的值时,我可以在我的网站上处理它.

Begin Try
 insert into BusinessID (BusinessID) values (@ID)
 insert into BusinessID (BusinessID) values (@ID)

End Try

Begin Catch

Print 'PK already exist'
THROW
End Catch

Answer 1

THROW声明在SQL Server 2012中引入

你可以RAISERROR改用.

BEGIN CATCH
    DECLARE @ErrorMessage NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState INT;

    SELECT 
        @ErrorMessage = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState = ERROR_STATE();

    RAISERROR (@ErrorMessage, -- Message text.
               @ErrorSeverity, -- Severity.
               @ErrorState -- State.
               );
END CATCH;
