本文介绍了SQL Server-如何在存储过程完成之前锁定表的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想这样做:

create procedure A as
  lock table a
  -- do some stuff unrelated to a to prepare to update a
  -- update a
  unlock table a
  return table b

有可能这样吗?

最终,我希望我的SQL Server报告服务报告调用过程A,然后在过程完成后仅显示表a. (我无法将过程A更改为返回表a).

Ultimately I want my SQL server reporting services report to call procedure A, and then only show table a after the procedure has finished. (I'm not able to change procedure A to return table a).

推荐答案

我本人也需要此答案,并通过David Moye提供的链接,对此进行了决定,并认为它可能对具有相同问题的其他人有用:

Needed this answer myself and from the link provided by David Moye, decided on this and thought it might be of use to others with the same question:

CREATE PROCEDURE ...
AS
BEGIN
  BEGIN TRANSACTION

  -- lock table "a" till end of transaction
  SELECT ...
  FROM a
  WITH (TABLOCK, HOLDLOCK)
  WHERE ...

  -- do some other stuff (including inserting/updating table "a")



  -- release lock
  COMMIT TRANSACTION
END
