我有两个DBF文件zhitag和zhitag2,结构一样,字段名tagname,现在想查找zhitag2中有但在和zhitag没有的tagname,并将查询到的结果生成一个新的表,并且表的结构和原来两个表的结构一样,原来的表有很多个字段名
------解决方案--------------------------------------------------------
&&这次生成3个表，需要那个用哪个，呵呵
&&newdbf0------zhitag有 zhitag2有
&&newdbf1------zhitag有 zhitag2无
&&newdbf2------zhitag无 zhitag2有
