数据|语句
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
