請問一下各位先進前輩
以下是我所有的語法
我應該把SQL LEFT JOIN 寫在那裡
目前我是寫在最下方,但沒有任何資料出來
本來是sql 2000 用的是 *= 可以執行,也有資料
公司昇級成 sql 2016 就無法執行了

  我照您的做法在最下面加上 LEFT JOIN CMSMV D ON  C.TI006=D.MV001 AND C.TI004=E.MA001
  出現錯誤訊息 
  接近關鍵字 'LEFT'之處的語法不正確,請問是為什麼呢

沒有看到全部程式.我也不知您錯在那裡.
只能講一下觀念:
在 TABLE JOIN(不管那一種JOIN) 時,這個TABLE 必須要先被 USED.
如:
FROM COPTG A LEFT JOIN CMSMV B ON A.TG006=B.MV001 AND A.TG004=C.MA001
LEFT JOIN COPMA C ON A.TG004=C.MA001
=> 這樣寫法:會報錯.因為COPMA 是在 ON A.TG006=B.MV001 AND A.TG004=C.MA001 才被USED
如果改為:
FROM COPTG A LEFT JOIN COPMA C ON A.TG004=C.MA001
LEFT JOIN CMSMV B ON A.TG006=B.MV001 AND A.TG004=C.MA001
這樣就不會報錯. 因為COPMA 已經先被USED .

您若對JOIN 語法不熟, 可以改用下列語法:
FROM COPTG A , CMSMV B , COPMA C
WHERE A.TG006=B.MV001(+) AND A.TG004=C.MA001(+)
上述語法等同於:
FROM COPTG A LEFT JOIN COPMA C ON A.TG004=C.MA001
LEFT JOIN CMSMV B ON A.TG006=B.MV001
