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>.

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

95 $self->_dbh->{ib_softcommit} = 1;
98 =head2 connect_call_datetime_setup
102 on_connect_call => 'datetime_setup'
104 In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set the date and
105 timestamp formats using:
107 $dbh->{ib_time_all} = 'ISO';
109 See L<DBD::InterBase> for more details.
111 The C<TIMESTAMP> data type supports up to 4 digits after the decimal point for
112 second precision. The full precision is used.
114 The C<DATE> data type stores the date portion only, and it B<MUST> be declared
119 in your Result class.
121 Timestamp columns can be declared with either C<datetime> or C<timestamp>.
123 You will need the L<DateTime::Format::Strptime> module for inflation to work.
125 For L<DBIx::Class::Storage::DBI::ODBC::Firebird>, this is a noop.
129 sub connect_call_datetime_setup {
132 $self->_get_dbh->{ib_time_all} = 'ISO';
141 with L</connect_call_use_softcommit>, you will not be able to see changes made
142 to data in other processes. If this is an issue, use
143 L<disable_sth_caching|DBIx::Class::Storage::DBI/disable_sth_caching> as a
144 workaround for the C<no statement executing> errors, this of course adversely
147 Alternately, use the L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver.
