Обсуждение: list or regular expressions

Hi all,
can i search in a list or regular expression....eg

"select yadi from ya where yadiya in ('old', 'ulk', 'orb')"

but instead of in ther'd be another operator or a LIKE IN.
so it'd be a shorcut for typing yadiya ~* 'old' or yadiya ~* 'ulk' etc.

You could use "<operator> ANY" --- "IN" is just a shorthand for "= ANY".
I don't think the parser will take LIKE ANY, but you could use the
equivalent operator name ("~~" I think, check the manual).

you mean, like

yadiya ~ 'old|ulk'

(or parametrically)

yadiya ~ ?::text ||'|'|| ?::text ||'|'|| ... :-)
