SQL 在同一字段中搜索多个值
我正在构建一个简单的搜索算法，我想用空格打破我的字符串，并在其上搜索我的数据库，如下所示:
I'm building a simple search algorithm and I want to break my string with spaces, and search my database on it, like so:
$search = "Sony TV with FullHD support";
$search = explode( ' ', $search );
SELECT name FROM Products WHERE name LIKE %$search[1]% AND name LIKE %$search[2]% LIMIT 6
这可能吗?
推荐答案
是的，可以使用 SQL IN 运算符搜索多个绝对值:
Yes, you can use SQL IN operator to search multiple absolute values:
SELECT name FROM products WHERE name IN ( 'Value1', 'Value2', ... );
如果你想使用 LIKE 你需要使用 OR 代替:
If you want to use LIKE you will need to use OR instead:
SELECT name FROM products WHERE name LIKE '%Value1' OR name LIKE '%Value2';
使用 AND(如您所尝试)需要所有条件都为真，使用 OR 需要至少一个条件为真.
Using AND (as you tried) requires ALL conditions to be true, using OR requires at least one to be true.
