Another option is to use the PCRE (Perl Compatable Regular Expressions) loadable module for SQLite for familar pattern matching via the
REGEXP function.
#!/usr/bin/perl
use warnings; use strict;
use 5.10.1;
use DBI;
my $dbh = DBI->connect("dbi:SQLite:dbname=/tmp/text.db", "", "", {Rais
+eError => 1});
# so we can use SQLite REGEXP operator
$dbh->sqlite_enable_load_extension(my $_enabled = 1);
$dbh->prepare("SELECT load_extension('/usr/lib/sqlite3/pcre.so')");
my $word = 'tag';
my $word_re = '\b'.quotemeta($word).'\b';
my $results = $dbh->selectall_arrayref("SELECT ID, sentence FROM tex
+ts WHERE sentence REGEXP ?", {}, $word_re);
foreach my $result (@$results) {
my ($id, $sentence) = @$result;
say "matched $id: $sentence";
}
Depending on your system it may be available as a package (Ubuntu has
sqlite3-pcre).
It's also available from github https://github.com/oojah/sqlite3-pcre where you can build and install it yourself.
