A good general resource: quotes in Perl, alas does not cover quotemeta. perlre covers \Q and \E usage; see also Quote and Quote-like Operators in perlop.

Super Searching for "quotemeta" turns up the following:

• Matching quoted variables. Cant make it work.. - excellent discussion; once again ikegami's reply really shines

Finally, here is the DBI quote function mentioned by davorg.

HTH,
