SQL指令改为:<p>Select A.Code, A.Item1, A.Item2 From Table1 A, Table2 B, Table3 C Where C.ItemName Like '%VB%') and A.code = B.code or A.code = C.code<p>1.以上只列出条件完全符合<br>A.code = B.code or A.code = C.code<br>的资料若有任一Table少了该Code(如:A,B皆有'AX123',而C没有时),该笔记录则不会被选出来。<p><br>2.你的错误讯息是什么?<p>3.如果你只是写测试程式或你的程式不注重速度,那使用rdc并无不当,否则还是建议你改用RDO<br>
