create table common_info(
name varchar(10),
value int)
insert into common_info values('msg_count', 100)
你的sql应该这么写(用存储过程):
create proc p_ins_alm_msg
    @msg_count     int out
as
    select @msg_count = value from common_info where name = 'msg_count'
    update common_info set value = @msg_count+ 1 where name = 'msg_count' and value =

@msg_count
        if @@rowcount = 0
            return -1000
    insert into table1 (field0)
    values(@msg_count)
    return 0
go
