php mysql多個OR語句

Question

我想運行一個簡單的mysql查詢，但它每次都沒有返回任何內容。出於某種原因，似乎有多個「OR」語句是原因。爲什麼？

返回null

mysql_query("SELECT * FROM table WHERE lower(Name)='arabic' or lower(Sub Name)='arabic' or lower(Language)='arabic'"); 

返回結果

mysql_query("SELECT * FROM table WHERE lower(Name)='arabic'"); 

Answer 1

您的列名，你應該圍繞列名和`符號

mysql_query("SELECT * FROM table WHERE lower(`Name`)='arabic' or lower(`Sub Name`)='arabic' or lower(`Language`)='arabic'");
