312 | =head2 connect_info |
313 | |
bb4f246d |
314 | The arguments of C<connect_info> are always a single array reference. |
1b45b01e |
315 | |
bb4f246d |
316 | This is normally accessed via L<DBIx::Class::Schema/connection>, which |
317 | encapsulates its argument list in an arrayref before calling |
318 | C<connect_info> here. |
1b45b01e |
319 | |
bb4f246d |
320 | The arrayref can either contain the same set of arguments one would |
321 | normally pass to L<DBI/connect>, or a lone code reference which returns |
322 | a connected database handle. |
d7c4c15c |
323 | |
2cc3a7be |
324 | In either case, if the final argument in your connect_info happens |
325 | to be a hashref, C<connect_info> will look there for several |
326 | connection-specific options: |
327 | |
328 | =over 4 |
329 | |
330 | =item on_connect_do |
331 | |
332 | This can be set to an arrayref of literal sql statements, which will |
333 | be executed immediately after making the connection to the database |
334 | every time we [re-]connect. |
335 | |
336 | =item limit_dialect |
337 | |
338 | Sets the limit dialect. This is useful for JDBC-bridge among others |
339 | where the remote SQL-dialect cannot be determined by the name of the |
340 | driver alone. |
341 | |
342 | =item quote_char |
d7c4c15c |
343 | |
2cc3a7be |
344 | Specifies what characters to use to quote table and column names. If |
345 | you use this you will want to specify L<name_sep> as well. |
346 | |
347 | quote_char expects either a single character, in which case is it is placed |
348 | on either side of the table/column, or an arrayref of length 2 in which case the |
349 | table/column name is placed between the elements. |
350 | |
351 | For example under MySQL you'd use C<quote_char =E<gt> '`'>, and user SQL Server you'd |
352 | use C<quote_char =E<gt> [qw/[ ]/]>. |
353 | |
354 | =item name_sep |
355 | |
356 | This only needs to be used in conjunction with L<quote_char>, and is used to |
357 | specify the charecter that seperates elements (schemas, tables, columns) from |
358 | each other. In most cases this is simply a C<.>. |
359 | |
360 | =back |
361 | |
362 | These options can be mixed in with your other L<DBI> connection attributes, |
363 | or placed in a seperate hashref after all other normal L<DBI> connection |
364 | arguments. |
365 | |
366 | Every time C<connect_info> is invoked, any previous settings for |
367 | these options will be cleared before setting the new ones, regardless of |
368 | whether any options are specified in the new C<connect_info>. |
369 | |
370 | Examples: |
371 | |
372 | # Simple SQLite connection |
bb4f246d |
373 | ->connect_info([ 'dbi:SQLite:./foo.db' ]); |
6789ebe3 |
374 | |
2cc3a7be |
375 | # Connect via subref |
bb4f246d |
376 | ->connect_info([ sub { DBI->connect(...) } ]); |
6789ebe3 |
377 | |
2cc3a7be |
378 | # A bit more complicated |
bb4f246d |
379 | ->connect_info( |
380 | [ |
381 | 'dbi:Pg:dbname=foo', |
382 | 'postgres', |
383 | 'my_pg_password', |
384 | { AutoCommit => 0 }, |
2cc3a7be |
385 | { quote_char => q{"}, name_sep => q{.} }, |
386 | ] |
387 | ); |
388 | |
389 | # Equivalent to the previous example |
390 | ->connect_info( |
391 | [ |
392 | 'dbi:Pg:dbname=foo', |
393 | 'postgres', |
394 | 'my_pg_password', |
395 | { AutoCommit => 0, quote_char => q{"}, name_sep => q{.} }, |

396 | ] |

402 | sub { DBI->connect(...) }, |
2cc3a7be |
403 | { |
404 | quote_char => q{`}, |
405 | name_sep => q{@}, |

6789ebe3 |
414 | |
92b858c9 |
415 | =head2 debug |
416 | |
4c248161 |
417 | Causes SQL trace information to be emitted on the C<debugobj> object. |
418 | (or C<STDERR> if C<debugobj> has not specifically been set). |
92b858c9 |
419 | |
f7a90adc |
420 | This is the equivalent to setting L</DBIC_TRACE> in your |
421 | shell environment. |
422 | |
92b858c9 |
423 | =head2 debugfh |
424 | |
4c248161 |
425 | Set or retrieve the filehandle used for trace/debug output. This should be |
426 | an IO::Handle compatible ojbect (only the C<print> method is used. Initially |
427 | set to be STDERR - although see information on the |
6fe735fa |
428 | L<DBIC_TRACE> environment variable. |

4c248161 |

451 | SELECT/INSERT/UPDATE/DELETE and $info is what would normally be printed. |

1108 | The module defines a set of methods within the DBIC::SQL::Abstract |
1109 | namespace. These build on L<SQL::Abstract::Limit> to provide the |
1110 | SQL query functions. |
1111 | |
1112 | The following methods are extended:- |
1113 | |
1114 | =over 4 |
1115 | |
1116 | =item delete |
1117 | |
1118 | =item insert |

1121 | |
1122 | =item update |
1123 | |
1124 | =item limit_dialect |
1125 | |

1126 | See L</connect_info> for details. |

1144 | |
6fe735fa |
1145 | If C<DBIC_TRACE> is set then SQL trace information |
92b858c9 |
1146 | is produced (as when the L<debug> method is set). |
1147 | |
1148 | If the value is of the form C<1=/path/name> then the trace output is |
1149 | written to the file C</path/name>. |
1150 | |
d1cceec4 |
1151 | This environment variable is checked when the storage object is first |
1152 | created (when you call connect on your schema). So, run-time changes |
1153 | to this environment variable will not take effect unless you also |
1154 | re-connect on your schema. |
