  • SQL2008多数据库查询表或删表

    SQL2008和2005多数据库操作,还是有一定的区别,采用这个方法是最好的,以下提供两种方法

    set nocount off
    declare @DBName as varchar(255)
    Create table #temp(Faccount varchar(255),FDate varchar(255),FDescription varchar(255))
    declare cs_DBName cursor for select name from sysdatabases where name like '%sy%' order by name
    open cs_DBName
    fetch next from cs_DBName into @DBName
    while @@fetch_Status =0
    begin
    exec('DELETE FROM '+@DBName+'.dbo.t_UserProfile')
    --select * from @DBName.dbo.t_log where substring(convert(varchar(108),fDATE,120),1,16)=@datetime
    --
    -- SELECT * FROM #temp drop table #temp
    fetch next from cs_DBName into @DBName
    end
    close cs_DBName
    DEALLOCATE cs_DBName

    -----------------------------------------------------------------------------------

    set nocount off
    declare @datetime as varchar(255)
    set @datetime='''2011-07-27 10:58'''
    declare @DBName as varchar(255)
    Create table #temp(Faccount varchar(255),FDate varchar(255),FDescription varchar(255))
    declare cs_DBName cursor for select name from sysdatabases where name like '%sy%' order by name
    open cs_DBName
    fetch next from cs_DBName into @DBName
    while @@fetch_Status =0
    begin
    exec('insert into #temp select '''+@DBName+''',fdate,FDescription from '+@DBName+ '.dbo.t_log where substring(convert(varchar(108),fDATE,120),1,16)='+@datetime+'')
    --select * from @DBName.dbo.t_log where substring(convert(varchar(108),fDATE,120),1,16)=@datetime
    --
    -- SELECT * FROM #temp drop table #temp
    fetch next from cs_DBName into @DBName
    end
    close cs_DBName
    DEALLOCATE cs_DBName
    select * from #temp
    drop table  #temp
