union这个连接是有什么用的和INNER JOIN有什么区别
Inner join 是两张表做交连后里面条件相同的部分记录产生一个记录集， <BR>union是产生的两个记录集(字段要一样的)并在一起，成为一个新的记录集 <br><br>Select A.Field1,B.field2 from Table1 A inner join Table2 B on a.Field2=b.Field2 where .......... <BR>Select Field1 from Table1 union Select Field2 from table2 <BR>方案二、<BR><DIV class=pubBody>select a.id,a.title,b.content from 表格1 as a,表格2 as b where a.id=b.id order by a.id<br><br>rs("id")<BR>rs("title")<BR>rs("content")</DIV>
<DIV class=pubBody>另：<BR>新建一个表xxx <br><br>sql="insert into xxx select P.id,P.title,M.content from picture P inner join miaoshu M on P.id=M.id" <BR>conn.execute sql <BR></DIV><BR>
