我从登陆界面,登陆后转到一个表单界面, 我希望这个表单能自动生成单据号,在网上找了很多办法都无法成功...郁闷死了.我的access数据库表member 其中的一列为 f_djh 假设我最后一条记录是20101001,是否可以在用户登陆后显示的这个表单界面或者是刷新这个界面, 单据号就读取数据库最后一个然后+1 显示出来新单据号.下面是我这个表单界面的源码:**********<td width="100"> </td>(希望能显示在红色这里)*********<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>

自动生成单号,直接从数据库中选择最大的号,然后加1不就行了吗?最主要的还是得做好同步,否则并发情况下会有多个用户同时使用这个单号。
