sql - 我无法使用 THROW SQL Server 2008 R2

Question

SQL Server 2008 R2 Management Studio 无法识别下面示例中的我的抛出，它说

incorrect syntax near Throw

我试图在这里抛出一个错误，这样当有人插入相同的值两次时我可以在我的网站中处理它。

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 语句是在SQL Server 2012中引入的

您可以使用RAISERROR来代替。

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;
