/**
* Create a condition to regex-pattern-check this field against a pattern
* <p>
* The SQL:2008 standard specifies a <code>&lt;regex like predicate></code>
* of the following form: <code><pre>
* &lt;regex like predicate> ::=
* &lt;row value predicand> &lt;regex like predicate part 2>
*
* &lt;regex like predicate part 2> ::=
* [ NOT ] LIKE_REGEX &lt;XQuery pattern> [ FLAG &lt;XQuery option flag> ]
* </pre></code>
* <p>
* This particular <code>LIKE_REGEX</code> operator comes in several
* flavours for various databases. jOOQ supports regular expressions as
* follows:
