如何用一個查詢刪除多個記錄

Question

我想用一個查詢使用mysql和php刪除多個記錄，而不是使用任何循環。

$query = "DELETE FROM countries c WHERE c.id = 8"; 

這是什麼語法？

Answer 1

$query = "DELETE FROM countries c WHERE c.id in(4,5,6,7,8,89,9, ....)"; 


$query = "DELETE FROM countries c WHERE c.id > 5 and c.id < 25"; 

Answer 2

我認爲你應該使用

$query = "DELETE FROM countries c WHERE c.id = 8 OR c.id = 9 OR c.id = 10"; 

沒有測試此代碼，但我認爲它應該工作。

Answer 3

如果你知道所有的id，你可以說 「WHERE c.id在（8,9,10）」
