自己做一个函数,然后写在公式里--方法1.创建一个自定义函数,得到最新编号
create function f_getid()
returns char(6)
as
begin
declare @re char(6)
select @re=max(编号字段) from 表
if @re is null
set @re='000001'
else
set @re=right('000000'+cast(cast(@re as bigint)+1 as varchar),6)
return(@re)
end
go--将编号字段的默认值设置为f_getid()
create table 表(编号字段 char(6) default 'ABC'+dbo.f_getid())
create function f_getid()
returns char(6)
as
begin
declare @re char(6)
select @re=max(编号字段) from 表
if @re is null
set @re='000001'
else
set @re=right('000000'+cast(cast(@re as bigint)+1 as varchar),6)
return(@re)
end
go--将编号字段的默认值设置为f_getid()
create table 表(编号字段 char(6) default 'ABC'+dbo.f_getid())

drop table 表
go
drop function dbo.f_getid
gocreate function f_getid()

create table 表(aaa varchar(100),编号字段 char(100) default 'ABC'+dbo.f_getid())
