316
317This class represents the connection to an RDBMS via L<DBI>. See
318L<DBIx::Class::Storage> for general information. This pod only
319documents DBI-specific methods and behaviors.

335
336=head2 connect_info
337
338The arguments of C<connect_info> are always a single array reference.
339
340This is normally accessed via L<DBIx::Class::Schema/connection>, which
341encapsulates its argument list in an arrayref before calling
342C<connect_info> here.
343
344The arrayref can either contain the same set of arguments one would
345normally pass to L<DBI/connect>, or a lone code reference which returns
346a connected database handle. Please note that the L<DBI> docs
347recommend that you always explicitly set C<AutoCommit> to either
348C<0> or C<1>. L<DBIx::Class> further recommends that it be set
349to C<1>, and that you perform transactions via our L</txn_do>
350method. L<DBIx::Class> will set it to C<1> if you do not do explicitly
351set it to zero. This is the default for most DBDs. See below for more
352details.
353
354In either case, if the final argument in your connect_info happens
355to be a hashref, C<connect_info> will look there for several
356connection-specific options:
357
358=over 4
359
360=item on_connect_do
361
362Specifies things to do immediately after connecting or re-connecting to
363the database. Its value may contain:
364
365=over
366
367=item an array reference
368
369This contains SQL statements to execute in order. Each element contains
370a string or a code reference that returns a string.
371
372=item a code reference
373
374This contains some code to execute. Unlike code references within an
375array reference, its return value is ignored.
376
377=back
378
379=item on_disconnect_do
380
381Takes arguments in the same form as L<on_connect_do> and executes them
382immediately before disconnecting from the database.
383
384Note, this only runs if you explicitly call L<disconnect> on the
385storage object.
386
387=item disable_sth_caching
388
389If set to a true value, this option will disable the caching of
390statement handles via L<DBI/prepare_cached>.
391
392=item limit_dialect
393
394Sets the limit dialect. This is useful for JDBC-bridge among others
395where the remote SQL-dialect cannot be determined by the name of the
396driver alone.
397
398=item quote_char
399
400Specifies what characters to use to quote table and column names. If
401you use this you will want to specify L<name_sep> as well.
402
403quote_char expects either a single character, in which case is it is placed
404on either side of the table/column, or an arrayref of length 2 in which case the
405table/column name is placed between the elements.
406
407For example under MySQL you'd use C<quote_char =E<gt> '`'>, and user SQL Server you'd
408use C<quote_char =E<gt> [qw/[ ]/]>.
409
410=item name_sep
411
412This only needs to be used in conjunction with L<quote_char>, and is used to
413specify the charecter that seperates elements (schemas, tables, columns) from
414each other. In most cases this is simply a C<.>.
415
416=item unsafe
417
418This Storage driver normally installs its own C<HandleError>, sets
419C<RaiseError> and C<ShowErrorStatement> on, and sets C<PrintError> off on
420all database handles, including those supplied by a coderef. It does this
421so that it can have consistent and useful error behavior.
422
423If you set this option to a true value, Storage will not do its usual
424modifications to the database handle's attributes, and instead relies on
425the settings in your connect_info DBI options (or the values you set in
426your connection coderef, in the case that you are connecting via coderef).
427
428Note that your custom settings can cause Storage to malfunction,
429especially if you set a C<HandleError> handler that suppresses exceptions
430and/or disable C<RaiseError>.
431
432=back
433
434These options can be mixed in with your other L<DBI> connection attributes,
435or placed in a seperate hashref after all other normal L<DBI> connection
436arguments.
437
438Every time C<connect_info> is invoked, any previous settings for
439these options will be cleared before setting the new ones, regardless of
440whether any options are specified in the new C<connect_info>.
441
442Another Important Note:
443
444DBIC can do some wonderful magic with handling exceptions,
445disconnections, and transactions when you use C<AutoCommit =&gt; 1>
446combined with C<txn_do> for transaction support.
447
448If you set C<AutoCommit =&gt; 0> in your connect info, then you are always
449in an assumed transaction between commits, and you're telling us you'd
450like to manage that manually. A lot of DBIC's magic protections
451go away. We can't protect you from exceptions due to database
452disconnects because we don't know anything about how to restart your
453transactions. You're on your own for handling all sorts of exceptional
454cases if you choose the C<AutoCommit =&gt 0> path, just as you would
455be with raw DBI.
456
457Examples:
458
459 # Simple SQLite connection
460 ->connect_info([ 'dbi:SQLite:./foo.db' ]);
461
462 # Connect via subref
463 ->connect_info([ sub { DBI->connect(...) } ]);
464
465 # A bit more complicated
466 ->connect_info(
467 [
468 'dbi:Pg:dbname=foo',
469 'postgres',
470 'my_pg_password',
471 { AutoCommit => 1 },
472 { quote_char => q{"}, name_sep => q{.} },
473 ]
474 );
475
476 # Equivalent to the previous example
477 ->connect_info(
478 [
479 'dbi:Pg:dbname=foo',
480 'postgres',
481 'my_pg_password',
482 { AutoCommit => 1, quote_char => q{"}, name_sep => q{.} },
483 ]
484 );
485
486 # Subref + DBIC-specific connection options
487 ->connect_info(
488 [
489 sub { DBI->connect(...) },
490 {
491 quote_char => q{`},
492 name_sep => q{@},
493 on_connect_do => ['SET search_path TO myschema,otherschema,public'],
494 disable_sth_caching => 1,
495 },
496 ]

544
545=head2 dbh_do
546
547Arguments: $subref, @extra_coderef_args?
548
549Execute the given subref using the new exception-based connection management.
550
551The first two arguments will be the storage object that C<dbh_do> was called
552on and a database handle to use. Any additional arguments will be passed
553verbatim to the called subref as arguments 2 and onwards.
554
555Using this (instead of $self->_dbh or $self->dbh) ensures correct
556exception handling and reconnection (or failover in future subclasses).
557
558Your subref should have no side-effects outside of the database, as
559there is the potential for your subref to be partially double-executed
560if the database connection was stale/dysfunctional.
561
562Example:
563
564 my @stuff = $schema->storage->dbh_do(
565 sub {
566 my ($storage, $dbh, @cols) = @_;
567 my $cols = join(q{, }, @cols);
568 $dbh->selectrow_array("SELECT $cols FROM foo");
