catch 块出错后如何继续？

Question

我有一个要求，我要循环 10 条记录，并将这些记录插入到事务中的 3 个不同的表中。我在 while 循环和事务中一次记录一条记录。

我的要求是，如果成功插入前 8 条记录，并且如果语句在第 9 条记录处失败，则应记录错误并继续插入第 10 条记录。

如果任何行有任何错误，存储过程不应停止。

我尝试将事务放入子 TRY-CATCH 块中，但仍然失败。

BEGIN TRY

DECLARE  @TotalRecord          AS INT = 10
        ,@LoopStartCount       AS INT = 1
        ,@AskPkQuotationId     AS INT;     

--Some select stuff here       
WHILE(@LoopStartCount <= @TotalRecord)
BEGIN 

    BEGIN TRY
    BEGIN TRAN

    --Do some insert update for each record.

    COMMIT TRAN
    END TRY

    BEGIN CATCH

    --Log Error and Continue with next record

    END CATCH
     SET @LoopStartCount = @LoopStartCount + 1;
    END



END TRY
BEGIN CATCH
 --Log parent error
END CATCH

尝试如下所示的方法。在 catch 部分，您可以处理该场景。

BEGIN TRY

DECLARE  @TotalRecord          AS INT = 10
        ,@LoopStartCount       AS INT = 1
        ,@AskPkQuotationId     AS INT;     

--Some select stuff here       
WHILE(@LoopStartCount <= @TotalRecord)
BEGIN 

    BEGIN TRY
    BEGIN TRAN 

    --Do some insert update for each record.

    COMMIT TRAN
    END TRY

    BEGIN CATCH
     
    --Log Error and Continue with next record
    IF @@TRANCOUNT >1
    
    BEGIN
    INSERT INTO dbo.ERROR_DETAILS --INSERTING ErrorInfo INTO LOG TABLE
    SELECT
        ERROR_NUMBER() AS ErrorNumber,
        ERROR_SEVERITY() AS ErrorSeverity,
        ERROR_STATE() AS ErrorState,
        ERROR_PROCEDURE() AS ErrorProcedure,
        ERROR_LINE() AS ErrorLine,
        ERROR_MESSAGE() AS ErrorMessage
    
    ROLLBACK TRAN 

    END
    GOTO LOOPCOUNTER1
    END CATCH
    LOOPCOUNTER1:
     SET @LoopStartCount = @LoopStartCount + 1;
    END
END

END TRY
BEGIN CATCH
 --Log parent error
END CATCH
