如何用sql语句修改数据表中字段，实现identity(100,1)
类别: MSSQL教程 
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
name varchar(10),
value int)
insert into common_info values(\'msg_count\', 100)
