如何用sql语句修改数据表中字段，实现identity(100,1)

create table common_info(
name varchar(10),
value int)
insert into common_info values('msg_count', 100)
您的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
