NAME

       DBIx::Class::Storage::DBI::SQLite - Automatic primary key class for SQLite

SYNOPSIS

         # In your table classes
         use base 'DBIx::Class::Core';
         __PACKAGE__->set_primary_key('id');

DESCRIPTION

       This class implements autoincrements for SQLite.

   Known Issues
       RT79576
            NOTE - This section applies to you only if ALL of these are true:

             * You are or were using DBD::SQLite with a version lesser than 1.38_01

             * You are or were using DBIx::Class versions between 0.08191 and 0.08209
               (inclusive) or between 0.08240-TRIAL and 0.08242-TRIAL (also inclusive)

             * You use objects with overloaded stringification and are feeding them
               to DBIC CRUD methods directly

           An unfortunate chain of events led to DBIx::Class silently hitting the problem
           described in RT#79576 <https://rt.cpan.org/Public/Bug/Display.html?id=79576>.

           In order to trigger the bug condition one needs to supply more than one bind value
           that is an object with overloaded stringification (numification is not relevant, only
           stringification is). When this is the case the internal DBIx::Class call to
           "$sth->bind_param" would be executed in a way that triggers the above-mentioned
           DBD::SQLite bug. As a result all the logs and tracers will contain the expected
           values, however SQLite will receive all these bind positions being set to the value of
           the last supplied stringifiable object.

           Even if you upgrade DBIx::Class (which works around the bug starting from version
           0.08210) you may still have corrupted/incorrect data in your database.  DBIx::Class
           warned about this condition for several years, hoping to give anyone affected
           sufficient notice of the potential issues. The warning was removed in 2015/v0.082820.

METHODS

   connect_call_use_foreign_keys
       Used as:

           on_connect_call => 'use_foreign_keys'

       In connect_info to turn on foreign key (including cascading) support for recent versions
       of SQLite and DBD::SQLite.

       Executes:

         PRAGMA foreign_keys = ON

       See <http://www.sqlite.org/foreignkeys.html> for more information.
