12 DBIx::Class::Storage::DBI::InterBase - Driver for the Firebird RDBMS via
17 This driver is a subclass of L<DBIx::Class::Storage::DBI::Firebird::Common> for
18 use with L<DBD::InterBase>, see that driver for general details.
20 You need to use either the
21 L<disable_sth_caching|DBIx::Class::Storage::DBI/disable_sth_caching> option or
22 L</connect_call_use_softcommit> (see L</CAVEATS>) for your code to function
23 correctly with this driver. Otherwise you will likely get bizarre error messages
24 such as C<no statement executing>. The alternative is to use the
25 L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver, which is more suitable
26 for long running processes such as under L<Catalyst>.
28 To turn on L<DBIx::Class::InflateColumn::DateTime> support, see
29 L</connect_call_datetime_setup>.

72 =head2 connect_call_use_softcommit
76 on_connect_call => 'use_softcommit'
78 In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set the
79 L<DBD::InterBase> C<ib_softcommit> option.
81 You need either this option or C<< disable_sth_caching => 1 >> for
82 L<DBIx::Class> code to function correctly (otherwise you may get C<no statement
83 executing> errors.) Or use the L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird>
86 The downside of using this option is that your process will B<NOT> see UPDATEs,
87 INSERTs and DELETEs from other processes for already open statements.

94 $self->_dbh->{ib_softcommit} = 1;
97 =head2 connect_call_datetime_setup
101 on_connect_call => 'datetime_setup'
103 In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set the date and
104 timestamp formats using:
106 $dbh->{ib_time_all} = 'ISO';
108 See L<DBD::InterBase> for more details.
110 The C<TIMESTAMP> data type supports up to 4 digits after the decimal point for
111 second precision. The full precision is used.
113 The C<DATE> data type stores the date portion only, and it B<MUST> be declared
118 in your Result class.
120 Timestamp columns can be declared with either C<datetime> or C<timestamp>.
122 You will need the L<DateTime::Format::Strptime> module for inflation to work.
124 For L<DBIx::Class::Storage::DBI::ODBC::Firebird>, this is a noop.
128 sub connect_call_datetime_setup {
131 $self->_get_dbh->{ib_time_all} = 'ISO';
140 with L</connect_call_use_softcommit>, you will not be able to see changes made
141 to data in other processes. If this is an issue, use
142 L<disable_sth_caching|DBIx::Class::Storage::DBI/disable_sth_caching> as a
143 workaround for the C<no statement executing> errors, this of course adversely
146 Alternately, use the L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver.
