关闭SqlServer连接

经常使用需要还原数据库又不想关闭已经打开的画面，所以直接上

 CREATE PROCEDURE [dbo].[StopLogin]
     @Dname varchar(50)
 AS
 DECLARE
     @name varchar(50),
     @s varchar(1000)
 BEGIN
     IF (@Dname = '')
     BEGIN
        DECLARE DataName CURSOR FOR
        SELECT name FROM sysdatabases WHERE name not in ('master')
        OPEN DataName
        FETCH NEXT FROM DataName
        INTO @name
        WHILE (@@FETCH_STATUS = 0)
        BEGIN
            DECLARE tb CURSOR local
            FOR
            SELECT N'kill   '+CAST(spid AS varchar)
            FROM master.dbo.sysprocesses
            WHERE dbid=db_id(@name)
            OPEN tb
            FETCH next FROM tb INTO @s
            WHILE @@FETCH_STATUS=0
            BEGIN
                EXEC(@s)
                FETCH NEXT FROM tb INTO @s
            END
            CLOSE tb
            DEALLOCATE tb
            FETCH NEXT FROM DataName
            INTO @name
        END
        CLOSE DataName
        DEALLOCATE DataName
     END
     ELSE
     BEGIN
     --声明游标 范围是select语句的内容
        DECLARE tb CURSOR local
        FOR
        --spid进程ID
        SELECT N'kill   '+CAST(spid AS varchar)
        FROM master.dbo.sysprocesses
        --db_id(@Dname) 获取数据库的id
        WHERE dbid=db_id(@Dname)
        --打开游标
        OPEN tb
        --获取游标内容存入@s中
        FETCH next FROM tb INTO @s
        --如果获取游标成功
        WHILE @@FETCH_STATUS=0
        BEGIN
             --执行@s 如：kill   56
            EXEC(@s)
             --获取游标内容存入@s中
            FETCH NEXT FROM tb INTO @s
        END
        --关闭游标
        CLOSE tb
        --取消本地游标的引用
        DEALLOCATE tb
     END
 END

使用方法 execute StopLogin @DbName

@DbName是数据库的名称，如果为'' 会关闭所有的连接除了master

注意：存储过程尽量在master库中，自己数据库中的话不能删除自己的连接。
