使用触发器来实现
create table test(
id varchar(20),
sname varchar(20)
)
create TRIGGER [test_insert] ON [dbo].[test]
INSTEAD OF INSERT
AS
declare @str varchar(20)
declare @i integer
set @str = 'BV'+left(convert(char,getdate(),112),6)
select @i=isnull(max(cast(right(rtrim(id),len(id)-8) as integer)),0) from
(select id from test where id like @str+'%') a
set @i=@i+1
INSERT INTO TEST
SELECT @STR++cast(@i as char)as id,sname from inserted
上面建好后执行：
insert into test(sname) values('test')
id字段会自动编好号
declare @XML XML
SET @XML='<root>
<OLDVALUE>
<H_Action id="1130">030</H_Action>
<D_Action>030</D_Action>
<OrderCompany>00220</OrderCompany>
<OrderNumber>10004035</OrderNumber> ......
