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 version 0.082900.
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
