我用来将这个存储过程添加到主数据库，

改进:

修剪主机名，这样复制粘贴就可以在VNC上工作。 增加了一个LOCK选项，用于查看当前锁定的进程。

用法:

EXEC sp_who3 'ACTIVE' EXEC sp_who3 'LOCK' EXEC sp_who3 spid_No

就是这样。

CREATE procedure sp_who3
       @loginame sysname = NULL --or 'active' or 'lock'
as

declare  @spidlow   int,
         @spidhigh  int,
         @spid      int,
         @sid       varbinary(85)

select   @spidlow   =     0
        ,@spidhigh  = 32767


if @loginame is not NULL begin
    if upper(@loginame) = 'ACTIVE' begin
        select spid, ecid, status
            , loginame=rtrim(loginame)
            , hostname=rtrim(hostname)
            , blk=convert(char(5),blocked)
            , dbname = case
                            when dbid = 0 then null
                            when dbid <> 0 then db_name(dbid)
                        end
              ,cmd
        from  master.dbo.sysprocesses
        where spid >= @spidlow and spid <= @spidhigh AND
              upper(cmd) <> 'AWAITING COMMAND'
        return (0)
    end
    if upper(@loginame) = 'LOCK' begin
        select spid , ecid, status
            , loginame=rtrim(loginame)
            , hostname=rtrim(hostname)
            , blk=convert(char(5),blocked)
            , dbname = case
                            when dbid = 0 then null
                            when dbid <> 0 then db_name(dbid)

              upper(cmd) <> 'AWAITING COMMAND'
        AND convert(char(5),blocked) > 0
        return (0)
    end

end

if (@loginame is not NULL
   AND  upper(@loginame) <> 'ACTIVE'
   )
begin
    if (@loginame like '[0-9]%')    -- is a spid.
    begin
        select @spid = convert(int, @loginame)
        select spid, ecid, status
            , loginame=rtrim(loginame)
            , hostname=rtrim(hostname)

/* loginame arg is null */

return (0) -- sp_who

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。

SQL Server 2005:

select * from sys.dm_os_performance_counters

select * from sys.dm_exec_requests

查找日期落在当前周内的记录。

where dateadd( week, datediff( week, 0, TransDate ), 0 ) =
dateadd( week, datediff( week, 0, getdate() ), 0 )

查找上周发生的日期记录。

where dateadd( week, datediff( week, 0, TransDate ), 0 ) =
dateadd( week, datediff( week, 0, getdate() ) - 1, 0 )

返回当前周的开始日期。

select dateadd( week, datediff( week, 0, getdate() ), 0 )

返回上周开始的日期。

select dateadd( week, datediff( week, 0, getdate() ) - 1, 0 )

好吧，这是我的观点:

我懒得在这里重新写一遍，所以请查看我的帖子。这对许多人来说可能是微不足道的，但会有一些人会发现它是一颗“隐藏的宝石”。

编辑:

过了一会儿，我决定在这里添加代码，这样您就不必跳转到我的博客来查看代码了。

SELECT  T.NAME AS [TABLE NAME], C.NAME AS [COLUMN NAME], P.NAME AS [DATA TYPE], P.MAX_LENGTH AS[SIZE],   CAST(P.PRECISION AS VARCHAR) +‘/’+ CAST(P.SCALE AS VARCHAR) AS [PRECISION/SCALE]
FROM ADVENTUREWORKS.SYS.OBJECTS AS T
JOIN ADVENTUREWORKS.SYS.COLUMNS AS C
ON T.OBJECT_ID=C.OBJECT_ID
JOIN ADVENTUREWORKS.SYS.TYPES AS P
ON C.SYSTEM_TYPE_ID=P.SYSTEM_TYPE_ID
WHERE T.TYPE_DESC=‘USER_TABLE’;

或者，如果你想拉出所有的用户表，像这样使用CURSOR:

DECLARE @tablename VARCHAR(60)

DECLARE cursor_tablenames CURSOR FOR
SELECT name FROM AdventureWorks.sys.tables

OPEN cursor_tablenames
FETCH NEXT FROM cursor_tablenames INTO @tablename

WHILE @@FETCH_STATUS = 0
BEGIN

SELECT  t.name AS [TABLE Name], c.name AS [COLUMN Name], p.name AS [DATA Type], p.max_length AS[SIZE],   CAST(p.PRECISION AS VARCHAR) +‘/’+ CAST(p.scale AS VARCHAR) AS [PRECISION/Scale]
FROM AdventureWorks.sys.objects AS t
JOIN AdventureWorks.sys.columns AS c
ON t.OBJECT_ID=c.OBJECT_ID
JOIN AdventureWorks.sys.types AS p
ON c.system_type_id=p.system_type_id
WHERE t.name = @tablename
AND t.type_desc=‘USER_TABLE’
ORDER BY t.name ASC

FETCH NEXT FROM cursor_tablenames INTO @tablename
END

CLOSE cursor_tablenames
DEALLOCATE cursor_tablenames

因为我是程序员，而不是DBA，所以我最喜欢的隐藏特性是SMO库。从数据库/表/列的创建和删除，到脚本编写，再到备份和恢复，在SQL Server中几乎任何事情都可以自动化。如果你能在SQL Server Management Studio中完成它，你也可以在SMO中自动化它。
