283=head2 connect_info
284
285This method is normally called by L<DBIx::Class::Schema/connection>, which
286encapsulates its argument list in an arrayref before passing them here.
287
288The argument list may contain:
289
290=over
291
292=item *
293
294The same 4-element argument set one would normally pass to
295L<DBI/connect>, optionally followed by
296L<extra attributes|/DBIx::Class specific connection attributes>
297recognized by DBIx::Class:
298
299 $connect_info_args = [ $dsn, $user, $password, \%dbi_attributes?, \%extra_attributes? ];
300
301=item *
302
303A single code reference which returns a connected
304L<DBI database handle|DBI/connect> optionally followed by
305L<extra attributes|/DBIx::Class specific connection attributes> recognized
306by DBIx::Class:
307
308 $connect_info_args = [ sub { DBI->connect (...) }, \%extra_attributes? ];
309
310=item *
311
312A single hashref with all the attributes and the dsn/user/password
313mixed together:
314
315 $connect_info_args = [{
316 dsn => $dsn,
317 user => $user,
318 password => $pass,
319 %dbi_attributes,
320 %extra_attributes,
321 }];
322
323 $connect_info_args = [{
324 dbh_maker => sub { DBI->connect (...) },
325 %dbi_attributes,
326 %extra_attributes,
327 }];
328
329This is particularly useful for L<Catalyst> based applications, allowing the
330following config (L<Config::General> style):
331
332 <Model::DB>
333 schema_class App::DB
334 <connect_info>
335 dsn dbi:mysql:database=test
336 user testuser
337 password TestPass
338 AutoCommit 1
339 </connect_info>
340 </Model::DB>
341
342The C<dsn>/C<user>/C<password> combination can be substituted by the
343C<dbh_maker> key whose value is a coderef that returns a connected
344L<DBI database handle|DBI/connect>
345
346=back
347
348Please note that the L<DBI> docs recommend that you always explicitly
349set C<AutoCommit> to either I<0> or I<1>. L<DBIx::Class> further
350recommends that it be set to I<1>, and that you perform transactions
351via our L<DBIx::Class::Schema/txn_do> method. L<DBIx::Class> will set it
352to I<1> if you do not do explicitly set it to zero. This is the default
353for most DBDs. See L</DBIx::Class and AutoCommit> for details.
354
355=head3 DBIx::Class specific connection attributes
356
357In addition to the standard L<DBI|DBI/ATTRIBUTES COMMON TO ALL HANDLES>
358L<connection|DBI/Database Handle Attributes> attributes, DBIx::Class recognizes
359the following connection options. These options can be mixed in with your other
360L<DBI> connection attributes, or placed in a separate hashref
361(C<\%extra_attributes>) as shown above.
362
363Every time C<connect_info> is invoked, any previous settings for
364these options will be cleared before setting the new ones, regardless of
365whether any options are specified in the new C<connect_info>.
366
367
368=over
369
370=item on_connect_do
371
372Specifies things to do immediately after connecting or re-connecting to
373the database. Its value may contain:
374
375=over
376
377=item a scalar
378
379This contains one SQL statement to execute.
380
381=item an array reference
382
383This contains SQL statements to execute in order. Each element contains
384a string or a code reference that returns a string.
385
386=item a code reference
387
388This contains some code to execute. Unlike code references within an
389array reference, its return value is ignored.
390
391=back
392
393=item on_disconnect_do
394
395Takes arguments in the same form as L</on_connect_do> and executes them
396immediately before disconnecting from the database.
397
398Note, this only runs if you explicitly call L</disconnect> on the
399storage object.
400
401=item on_connect_call
402
403A more generalized form of L</on_connect_do> that calls the specified
404C<connect_call_METHOD> methods in your storage driver.
405
406 on_connect_do => 'select 1'
407
408is equivalent to:
409
410 on_connect_call => [ [ do_sql => 'select 1' ] ]
411
412Its values may contain:
413
414=over
415
416=item a scalar
417
418Will call the C<connect_call_METHOD> method.
419
420=item a code reference
421
422Will execute C<< $code->($storage) >>
423
424=item an array reference
425
426Each value can be a method name or code reference.
427
428=item an array of arrays
429
430For each array, the first item is taken to be the C<connect_call_> method name
431or code reference, and the rest are parameters to it.
432
433=back
434
435Some predefined storage methods you may use:
436
437=over
438
439=item do_sql
440
441Executes a SQL string or a code reference that returns a SQL string. This is
442what L</on_connect_do> and L</on_disconnect_do> use.
443
444It can take:
445
446=over
447
448=item a scalar
449
450Will execute the scalar as SQL.
451
452=item an arrayref
453
454Taken to be arguments to L<DBI/do>, the SQL string optionally followed by the
455attributes hashref and bind values.
456
457=item a code reference
458
459Will execute C<< $code->($storage) >> and execute the return array refs as
460above.
461
462=back
463
464=item datetime_setup
465
466Execute any statements necessary to initialize the database session to return
467and accept datetime/timestamp values used with
468L<DBIx::Class::InflateColumn::DateTime>.
469
470Only necessary for some databases, see your specific storage driver for
471implementation details.
472
473=back
474
475=item on_disconnect_call
476
477Takes arguments in the same form as L</on_connect_call> and executes them
478immediately before disconnecting from the database.
479
480Calls the C<disconnect_call_METHOD> methods as opposed to the
481C<connect_call_METHOD> methods called by L</on_connect_call>.
482
483Note, this only runs if you explicitly call L</disconnect> on the
484storage object.
485
486=item disable_sth_caching
487
488If set to a true value, this option will disable the caching of
489statement handles via L<DBI/prepare_cached>.
490
491=item limit_dialect
492
493Sets a specific SQL::Abstract::Limit-style limit dialect, overriding the
494default L</sql_limit_dialect> setting of the storage (if any). For a list
495of available limit dialects see L<DBIx::Class::SQLMaker::LimitDialects>.
496
497=item quote_names
498
499When true automatically sets L</quote_char> and L</name_sep> to the characters
500appropriate for your particular RDBMS. This option is preferred over specifying
501L</quote_char> directly.
502
503=item quote_char
504
505Specifies what characters to use to quote table and column names.
506
507C<quote_char> expects either a single character, in which case is it
508is placed on either side of the table/column name, or an arrayref of length
5092 in which case the table/column name is placed between the elements.
510
511For example under MySQL you should use C<< quote_char => '`' >>, and for
512SQL Server you should use C<< quote_char => [qw/[ ]/] >>.
513
514=item name_sep
515
516This parameter is only useful in conjunction with C<quote_char>, and is used to
517specify the character that separates elements (schemas, tables, columns) from
518each other. If unspecified it defaults to the most commonly used C<.>.
519
520=item unsafe
521
522This Storage driver normally installs its own C<HandleError>, sets
523C<RaiseError> and C<ShowErrorStatement> on, and sets C<PrintError> off on
524all database handles, including those supplied by a coderef. It does this
525so that it can have consistent and useful error behavior.
526
527If you set this option to a true value, Storage will not do its usual
528modifications to the database handle's attributes, and instead relies on
529the settings in your connect_info DBI options (or the values you set in
530your connection coderef, in the case that you are connecting via coderef).
531
532Note that your custom settings can cause Storage to malfunction,
533especially if you set a C<HandleError> handler that suppresses exceptions
534and/or disable C<RaiseError>.
535
536=item auto_savepoint
537
538If this option is true, L<DBIx::Class> will use savepoints when nesting
539transactions, making it possible to recover from failure in the inner
540transaction without having to abort all outer transactions.
541
542=item cursor_class
543
544Use this argument to supply a cursor class other than the default
545L<DBIx::Class::Storage::DBI::Cursor>.
546
547=back
548
549Some real-life examples of arguments to L</connect_info> and
550L<DBIx::Class::Schema/connect>

798
799Arguments: ($subref | $method_name), @extra_coderef_args?
800
801Execute the given $subref or $method_name using the new exception-based
802connection management.
803
804The first two arguments will be the storage object that C<dbh_do> was called
805on and a database handle to use. Any additional arguments will be passed
806verbatim to the called subref as arguments 2 and onwards.
807
808Using this (instead of $self->_dbh or $self->dbh) ensures correct
809exception handling and reconnection (or failover in future subclasses).
810
811Your subref should have no side-effects outside of the database, as
812there is the potential for your subref to be partially double-executed
813if the database connection was stale/dysfunctional.

818 sub {

820 my $cols = join(q{, }, @cols);

2754This method is always called after the driver has been determined and a DBI
2755connection has been established. Therefore you can refer to C<DBI::$constant>

2757the correct modules.

2767Given a datatype from column_info, returns a boolean value indicating if
2768the current RDBMS considers it a numeric value. This controls how
2769L<DBIx::Class::Row/set_column> decides whether to mark the column as
2770dirty - when the datatype is deemed numeric a C<< != >> comparison will
2771be performed instead of the usual C<eq>.

2793
2794Creates a SQL file based on the Schema, for each of the specified
2795database engines in C<\@databases> in the given directory.
2796(note: specify L<SQL::Translator> names, not L<DBI> driver names).
2797
2798Given a previous version number, this will also create a file containing
2799the ALTER TABLE statements to transform the previous schema into the
2800current one. Note that these statements may contain C<DROP TABLE> or
2801C<DROP COLUMN> statements that can potentially destroy data.
2802
2803The file names are created using the C<ddl_filename> method below, please
2804override this method in your schema if you would like a different file
2805name format. For the ALTER file, the same format is used, replacing
2806$version in the name with "$preversion-$version".
2807
2808See L<SQL::Translator/METHODS> for a list of values for C<\%sqlt_args>.
2809The most common value for this would be C<< { add_drop_table => 1 } >>
2810to have the SQL produced include a C<DROP TABLE> statement for each table
2811created. For quoting purposes supply C<quote_identifiers>.
2812
2813If no arguments are passed, then the following default values are assumed:
2814

2821=item directory - './'
2822
2823=item preversion - <none>
2824
2825=back
2826
2827By default, C<\%sqlt_args> will have
2828
2829 { add_drop_table => 1, ignore_constraint_names => 1, ignore_index_names => 1 }
2830
2831merged with the hash passed in. To disable any of those features, pass in a

3257=head1 USAGE NOTES
3258
3259=head2 DBIx::Class and AutoCommit
3260
3261DBIx::Class can do some wonderful magic with handling exceptions,
3262disconnections, and transactions when you use C<< AutoCommit => 1 >>
3263(the default) combined with L<txn_do|DBIx::Class::Storage/txn_do> for
3264transaction support.
3265
3266If you set C<< AutoCommit => 0 >> in your connect info, then you are always
3267in an assumed transaction between commits, and you're telling us you'd
3268like to manage that manually. A lot of the magic protections offered by
3269this module will go away. We can't protect you from exceptions due to database
3270disconnects because we don't know anything about how to restart your
3271transactions. You're on your own for handling all sorts of exceptional
3272cases if you choose the C<< AutoCommit => 0 >> path, just as you would
3273be with raw DBI.
