mysql 中不区分大小写的查询
问题描述：
我需要查询我的数据库并找到结果:
i need to query my database and find results :
mysql_query("select * from ".ALU_TABLE." where username like '%$q%' or name like '%$q%'");
如果我的表格中有一个名称，例如 Book 并且我在搜索框中输入 book，它不会显示该 Book
if i have a name in my table such as Book and i enter book in search box it wont show the Book
我需要查询我的数据库，因为不区分大小写.
i need to query my database as not to be case sensitive.
答
你可以使用LOWER()函数
... WHERE LOWER(username) LIKE blabl OR LOWER(name) LIKE asdasd
