如何配置 query governor cost limit 选项 (SQL Server Management Studio)
更新日期： 2007 年 9 月 15 日
使用 query governor cost limit 选项指定查询可以运行的时间段上限。 查询开销是指在特定硬件配置中完成查询所需的估计占用时间（秒）。
设置
query governor cost limit 选项
-
在对象资源管理器中，右键单击服务器并选择“属性”。
-
单击“连接”页。
-
选中或清除“使用查询调控器防止查询长时间运行”复选框。
如果选中此复选框，请在下面的框中输入一个正值，查询调控器将禁止执行运行长度超过该值的所有查询。
其实最好的是不勾选该选项，设置为0就可以了
