*- +
* <p>If a regular expression is used as a pattern, an SQL regular expression will be- +

* that MySQL and PostgreSQL regular expression syntax is similar to javascript- +
* regular expression syntax, but it not exactly the same, especially for- +
* advanced regular expression features. Patio just uses the source of the- +

* <p>If any other object is used as a regular expression, the SQL LIKE operator will- +
