Custom REGEXP Function to be used in a SQLITE SELECT Statement

Question

I have an SQLITE Database\'s File which in one of the table columns there is some simple Regular Expressions.

These Expressions are something like /foo(.

Answer 1

Is this what you are looking for?

e.g. SELECT * FROM `my_table` WHERE `my_column` REGEXP "\/foo(.?)"

Answer 2

You can use SQLiteDatabase::createFunction documentation here or PDO::sqliteCreateFunction documentation here

I did something like this:

<?php
function _sqliteRegexp($string, $pattern) {
    if(preg_match('/^'.$pattern.'$/i', $string)) {
        return true;
    }
    return false;
}
$PDO->sqliteCreateFunction('regexp', '_sqliteRegexp', 2);
?>

Use:

SELECT route FROM routes WHERE pattern REGEXP 'your/url/string' LIMIT 1
