請問如何在Table A, B, C A Left Join B, B Left Join C呢? 如何去寫呢? eg. Select * from A Left Join B On (B.PID = A.P_ID) Left Join C On (C.QID = A.Q_ID) 這個方法是b,c depend on a,但如果c是depend on b呢?怎樣寫?謝

Hi BorlandUser 兄你好:    Select * from A Left Join B On (B.PID = A.P_ID) Left Join C On (C.QID = B.Q_ID) 我不是高手, 高手是正在銀幕前微笑的人.
