用sql语句修改数据表中字段 实现identity(100,1)的递增

>

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
