How I can make a query with MySQL that checks if the valuein a certain column contains certain data

0 votes

I've been trying to figure out how I can make a query with MySQL that checks if the value (string $haystack ) in a certain column contains certain data (string $needle), like this:

mysql_query("
SELECT *
FROM `table`
WHERE `column`.contains('{$needle}')
");

In PHP, the function is called substr($haystack, $needle), so maybe:

WHERE substr(`column`, '{$needle}')=1

Hello @kartik,

Try this query:

mysql_query("
SELECT *
FROM `table`
WHERE `column` LIKE '%{$needle}%'
");

The % is a wildcard for any characters set (none, one or many). Do note that this can get slow on very large datasets so if your database grows you'll need to use fulltext indices.

Hope it helps!!
Thank you!!
