SQL删除TOP语句

Question

我的表（sql sever 2000）包含大量行，当我删除行时，它非常慢。

我看到一些帖子/论坛建议使用WHILE循环功能批量删除记录。

我的sql是：

DELETE FROM Tprs_master where Fincmonth='201109';

我改写为：

DELETE FROM(SELECT TOP 100 FROM tprs_master) AS t1 WHERE t1.Fincmonth='201109'

但它不起作用。

如何将上面的sql重写为DELETE TOP样式？感谢

Answer 1

MSDN DELETE page提供了示例和语法

DELETE TOP (100) FROM Tprs_master where Fincmonth='201109';

注意：仅限SQL Server 2005+

另请参阅更多示例Bulk DELETE on SQL Server 2008 (Is there anything like Bulk Copy (bcp) for delete data?)

编辑：OP有SQL Server 2000

SET ROWCOUNT 100
DELETE FROM Tprs_master where Fincmonth='201109';
SET ROWCOUNT 0
