我想能夠刪除ID-12345,12347的數據，但是當我嘗試刪除12346時，sholud不能被刪除becoz它在另一個表 –

我認爲你有外鍵扭曲這兩個表。刪除之前從自己的記錄與該ID – splash58

你可以嘗試這樣的：

delete from add_member where member_ID not exists(select member_ID from ownbook)

，或者您可以使用NOT IN像

delete from add_member where member_ID not in(select member_ID from ownbook)

如果它是具體數據，然後簡單地做：

delete from add_member 
where member_ID not in(select member_ID from ownbook where member_id in(12345,12347))

，但我想刪除特定數據2345或2347但不是2346 becoz它是在另一個表 –

它刪除兩個數據...我想刪除一個數據 –

我想刪除12345 ID只 –

如果你wan T刪除一個特定的ID，當且僅當它不應該在第二個表在那裏，你可以這樣做：

delete from add_member where member_ID='SEPCIFIC_ID_YOU_WANT' and member_ID not in(select member_ID from ownbook)

工作100％測試。
