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)
                        end
              ,cmd
        from  master.dbo.sysprocesses
        where spid >= 0 and spid <= 32767 AND
              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)

        begin

            return (1)
        end

登录事件的触发器

Logon triggers can help complement auditing and compliance. For example, logon events can be used for enforcing rules on connections (for example limiting connection through a specific username or limiting connections through a username to a specific time periods) or simply for tracking and recording general connection activity. Just like in any trigger, ROLLBACK cancels the operation that is in execution. In the case of logon event that means canceling the connection establishment. Logon events do not fire when the server is started in the minimal configuration mode or when a connection is established through dedicated admin connection (DAC).

执行一个存储过程，并在(temp)表中捕获结果，以便进一步处理，例如:

INSERT INTO someTable EXEC sp_someproc

示例:显示sp_help输出，但按数据库大小排序:

CREATE TABLE #dbs
(
    name nvarchar(50),
    db_size nvarchar(50),
    owner nvarchar(50),
    dbid int,
    created datetime,
    status nvarchar(255),
    compatiblity_level int
)
INSERT INTO #dbs EXEC sp_helpdb

SELECT * FROM #dbs 
ORDER BY CONVERT(decimal, LTRIM(LEFT(db_size, LEN(db_size)-3))) DESC

DROP TABLE #dbs

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)

下面是我写的一个查询，按最后修改日期列出所有DB用户对象:

select name, modify_date, 
case when type_desc = 'USER_TABLE' then 'Table'
when type_desc = 'SQL_STORED_PROCEDURE' then 'Stored Procedure'
when type_desc in ('SQL_INLINE_TABLE_VALUED_FUNCTION', 'SQL_SCALAR_FUNCTION', 'SQL_TABLE_VALUED_FUNCTION') then 'Function'
end as type_desc
from sys.objects
where type in ('U', 'P', 'FN', 'IF', 'TF')
and is_ms_shipped = 0
order by 2 desc

/*找到空闲空间最大的固定驱动器，也可以复制文件来估计哪个磁盘最快*/

EXEC master..xp_fixeddrives

/*在使用或引用之前检查文件的假设*/
