Question

我需要从SQL Server 2008中的2个表中删除数据。

我有两个表A和B.我需要将每个表放在一个单独的事务中。

这是我正在使用的代码。

BEGIN TRANSACTION;
BEGIN TRY
    DELETE      from A
END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;

END CATCH

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;


BEGIN TRANSACTION;
BEGIN TRY
    DELETE     from B
END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;

有没有更好的方法在SQL Server中实现多个事务和错误处理？

我需要为每个表添加单独的事务。

当其中一个交易失败时，我收到错误。

EXECUTE后的事务计数表示不匹配的数量 BEGIN和COMMIT语句。记录不会从其他记录中删除交易

Answer 1

试试这个：

BEGIN TRANSACTION;
BEGIN TRY
    DELETE from A
    COMMIT TRANSACTION;
END TRY
BEGIN CATCH
ROLLBACK TRANSACTION;
END CATCH


BEGIN TRANSACTION;
BEGIN TRY
    DELETE     from B
    COMMIT TRANSACTION;
END TRY
BEGIN CATCH
    ROLLBACK TRANSACTION;
END CATCH

可能你可以这样做：

BEGIN TRANSACTION one;
BEGIN TRY
    DELETE      from A
END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION one;

END CATCH

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION one;


BEGIN TRANSACTION two;
BEGIN TRY
    DELETE     from B
END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION two;
END CATCH

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION two;
