存储过程

sp_msforeachtable: Runs a command with '?' replaced with each table name (v6.5 and up) sp_msforeachdb: Runs a command with '?' replaced with each database name (v7 and up) sp_who2: just like sp_who, but with a lot more info for troubleshooting blocks (v7 and up) sp_helptext: If you want the code of a stored procedure, view & UDF sp_tables: return a list of all tables and views of database in scope. sp_stored_procedures: return a list of all stored procedures xp_sscanf: Reads data from the string into the argument locations specified by each format argument. xp_fixeddrives:: Find the fixed drive with largest free space sp_help: If you want to know the table structure, indexes and constraints of a table. Also views and UDFs. Shortcut is Alt+F1

下面是一些我喜欢的SQL Management Studio隐藏特性。

我喜欢的一点是，如果你在高亮显示信息时按住ALT键，你可以选择柱状信息，而不仅仅是整行。

在SQL Management Studio中，你有预定义的快捷键:

Ctrl+1运行sp_who Ctrl+2运行sp_lock Alt+F1运行sp_help Ctrl+F1运行sp_helptext

因此，如果您在编辑器中突出显示表名并按Alt+F1，它将显示表的结构。

其他回答

在Management Studio中，你可以在GO批处理结束标记后面放一个数字，以使批处理重复该次数:

PRINT 'X'
GO 10

将打印'X' 10次。这可以让你在做重复的事情时避免繁琐的复制/粘贴。

如果您想删除数据库中的所有过程-

SELECT  IDENTITY ( int, 1, 1 ) id, 
        [name] 
INTO    #tmp 
FROM    sys.procedures 
WHERE   [type]        = 'P' 
    AND is_ms_shipped = 0 

DECLARE @i INT 

SELECT   @i = COUNT( id ) FROM #tmp 
WHILE    @i > 0 
BEGIN 
   DECLARE @name VARCHAR( 100 ) 
   SELECT @name = name FROM #tmp WHERE id = @i 
   EXEC ( 'DROP PROCEDURE ' + @name ) 
   SET @i = @i-1 
END

DROP TABLE #tmp

在SQL Server 2005中，您不再需要运行sp-blocker-pss80存储过程。相反，你可以这样做:

exec sp_configure 'show advanced options', 1;
reconfigure;
go
exec sp_configure 'blocked process threshold', 30;
reconfigure;

然后，您可以启动SQL跟踪，并在“错误和警告”组中选择“阻塞”流程报告事件类。详情请点击这里。

基于强硬的数据库开发人员对它的强烈反应，CLR集成应该排在前面。=）
