如何用sql语句修改数据表中字段，实现identity(100,1)

核心提示：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_

　　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
