Hi,
I noticed in recent versions of SQLite the addition of some functions
such as Trim(). So I am hopeful that at least one more function,
Regexp(), can be included since it is such a central and common need.
Time and time again I come up with needing a Regexp function, and I
notice that the SQLite expression syntax even caters for it, but
doesn't actually implement it.
I need full PCRE (ie Perl Compatible Regular Expression) support, for
things such as grouping, replacing, "g i s" options.
For instance, Trim() could have been accomplished via Regexp, such as:
Trim = ' text between spaces ' Regexp '/[:space:]*(.*?)[:space:]*/s'
I'm not sure how the SQLite syntax should cater for extracting a
particular group from the match (ie the text match between the
brackets above).
I know there are hooks for adding a Regexp function/operator
ourselves, but I need to know it's available on other machines with
standard install. It's the same reasoning, I guess, as why Trim() was
added, but Regexp seems to serve a wider need.
Please and thankyou,
Tom
