SQLServer在多个表中都增加一个字段的方法

declare @sql varchar(200), @name varchar(40)
declare my_cursor scroll cursor for
    select name from sysobjects where type = ‘u‘ and name like ‘jobs_%‘
open my_cursor
fetch next from my_cursor into @name
while(@@fetch_status=0)
begin
    print ‘processing ‘ + @name
    set @sql = N‘alter table testbfcmisuser.‘ + @name + N‘ add note varchar(200)‘
    exec(@sql)
    print ‘finished‘
    fetch next from my_cursor into @name
end
close my_cursor
deallocate my_cursor

declare @sql varchar(200), @name varchar(100), @count int

select identity(int, 1, 1) as ID, name
    into #JobTable
    from sysobjects
    where type = ‘u‘ and name like   ‘Jobs_%‘

set   @count=@@rowcount

while   @count>0
begin
    select top 1 @name = name 
        from #JobTable
        where id = @count

    print    ‘processing ‘ + @name
    set @sql = N‘alter table testbfcmisuser.‘ + @name + N‘ add note varchar(200)‘
    exec(@sql)
    print ‘finished‘
        set @count = @count - 1
end

drop   table   #JobTable
