如何在 sql server 2005 中获取数据库连接的详细列表？

Answer 1

使用系统存储过程sp_who2 。

Answer 2

sp_who2 will actually provide a list of connections for the database server , not a database . To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2 .)

Answer 3

As @Hutch pointed out, one of the major limitations of sp_who2 is that it does not take any parameters so you cannot sort or filter it by default. You can save the results into a temp table , but then the you have to declare all the types ahead of time ( and remember to DROP TABLE ).

Instead, you can just go directly to the source on master.dbo.sysprocesses

I've constructed this to output almost exactly the same thing that sp_who2 generates, except that you can easily add ORDER BY and WHERE clauses to get meaningful output.

SELECT  spid,
        sp.[status],
        loginame [Login],
        hostname, 
        blocked BlkBy,
        sd.name DBName, 
        cmd Command,
        cpu CPUTime,
        physical_io DiskIO,
        last_batch LastBatch,
        [program_name] ProgramName   
FROM master.dbo.sysprocesses sp 
JOIN master.dbo.sysdatabases sd ON sp.dbid = sd.dbid
ORDER BY spid 

Answer 4

There is also who is active? :

Who is Active? is a comprehensive server activity stored procedure based on the SQL Server 2005 and 2008 dynamic management views (DMVs). Think of it as sp_who2 on a hefty dose of anabolic steroids
