表/存储过程过滤器是一个半隐藏的特性，非常有用…

在“SQL Server Management Studio对象资源管理器”中，右键单击“表或存储过程”文件夹，选择“筛选器”菜单，然后选择“筛选器设置”，并在“名称包含”行中输入部分名称。

同样地，使用Remove Filter再次查看所有表/存储过程。

这是我今天学到的一个，因为我需要搜索一笔交易。

:: fn_dblog 这允许您查询数据库的事务日志。

USE mydatabase;
SELECT *
FROM ::fn_dblog(NULL, NULL)

存储过程的一个技巧是可以从INSERT语句调用它们。当我在SQL Server数据库上工作时，我发现这非常有用。

CREATE TABLE #toto (v1 int, v2 int, v3 char(4), status char(6))
INSERT #toto (v1, v2, v3, status) EXEC dbo.sp_fulubulu(sp_param1)
SELECT * FROM #toto
DROP TABLE #toto
