我写了一个交易,如:

    BEGIN TRAN

    UPDATE  [Table1]
    SET [Name] = 'abcd'
    WHERE   [ID] = 1

    UPDATE  [Table2]
    SET [Product] = 'efgh'
    WHERE   [ID] = 10

    UPDATE  [Table3]
    SET [Customar] = 'ijkl'
    WHERE   [ID] = 11

现在,如果任何 UPDATE 不成功,我想回滚。例如,在表 2 中,如果没有 ID=10 的产品,则应回滚事务。怎么做?请注意,我使用的是 SQLServer 2000.

最佳答案

SQL Server 2000。如果使用 SET XACT_ABORT ON,则不需要回滚

SET XACT_ABORT ON --to ensure rollback
BEGIN TRAN -- @@TRANCOUNT + 1

UPDATE  [Table1]
SET [Name] = 'abcd'
WHERE   [ID] = 1
IF @@ROWCOUNT = 0 ROLLBACK TRAN

IF @@TRANCOUNT > 0
BEGIN
    UPDATE  [Table2]
    SET [Product] = 'efgh'
    WHERE   [ID] = 10

    IF @@ROWCOUNT = 0 ROLLBACK TRAN
END

IF @@TRANCOUNT > 0
BEGIN
    UPDATE  [Table3]
    SET [Customar] = 'ijkl'
    WHERE   [ID] = 11

    IF @@ROWCOUNT = 0 ROLLBACK TRAN
END

IF @@TRANCOUNT > 0 COMMIT TRAN
