I'm using various languages such as Ruby, PERL, RB, etc. I have need to use regular expressions in some of my queries, but I'm not sure how to implement user defined functionality. Where are the hooks? Is there a particular mechanism/language I must use to create them? Is this something I'm required to recompile SQLITE for? You do so by defining a user function called 'regexp'. The means by which one defines a user function depends on the language. See, for instance, [1] for Ruby. For a 'regexp' function you would specify two arguments, pattern and string to match against. [1] http://sqlite-ruby.rubyforge.org/sqlite3/classes/SQLite3/Datab ase.html#M000115 -- J. King Hi, If you use Perl, make sure to get the latest version of DBD::SQLite, where the SQLite regexp function is automatically hooked to Perl regexes. See http://search.cpan.org/dist/DBD-SQLite/lib/DBD/SQLite.pm#REGEXP_function : SQLite includes syntactic support for an infix operator 'REGEXP', but without any implementation. The DBD::SQLite driver automatically registers an implementation that performs standard perl regular expression matching, using current locale. So for example you can search for words starting with an 'A' with a query like SELECT * from table WHERE column REGEXP '\bA\w+' If you want case-insensitive searching, use perl regex flags, like this : SELECT * from table WHERE column REGEXP '(?i:\bA\w+)' ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

Would it be possible for you to setup Process Monitor with filter on the database path (just the path, so both journal and the main database file are in the log) and history depth set to 1 million (the lowest value) and then capture the file accesses during the run of the reproduction scripts?

[sqlite] Index Problem
Hi Friends, I ran into a big problem of creating indexes taking a long time. When i create index on multiple colomns then its taking a long time on few machines. Those are windows Vista machines. I am using following command: CREATE INDEX IF NOT EXISTS New_Index (name,title) I tried with empty database also again its taking long time. Since indexes are already created then why its taking long time. Its taking time from 500-800 ms. while on other machines its taking less time 40-80 ms.
