如何捕捉分布式事务中的“严重错误”？

Question

在分布式事务中，尝试插入违反唯一键的值时会发生“严重错误”。如何捕获“严重错误”？

示例查询1

SET XACT_ABORT ON
BEGIN DISTRIBUTED TRAN
    BEGIN TRY
        INSERT INTO [LINKEDSERVER].[DB].[SCHEMA].[TABLE] VALUES(THE VALUES Violation of UNIQUE KEY)
    END TRY
COMMIT TRAN
BEGIN CATCH
    ROLLBACK TRAN
    PRINT ERROR_MESSAGE()
END CATCH

结果1

*Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.*

示例查询2

INSERT INTO [LINKEDSERVER].[DB].[SCHEMA].[TABLE] VALUES(THE VALUES Violation of UNIQUE KEY)

结果2

Msg 2627, Level 14, State 1, Line 1
Violation of UNIQUE KEY constraint 'XXX'. Cannot insert duplicate key in object '[SCHEMA].[TABLE]'. The duplicate key value is (XXX).
