234 | |
235 | DBIx::Class::Storage::DBI - DBI storage handler |
236 | |
237 | =head1 SYNOPSIS |
238 | |
239 | =head1 DESCRIPTION |
240 | |
241 | This class represents the connection to the database |
242 | |
243 | =head1 METHODS |
244 | |
8b445e33 |
245 | =cut |
246 | |
d7c4c15c |
247 | =head2 on_connect_do |
248 | |
249 | Executes the sql statements given as a listref on every db connect. |
250 | |
92b858c9 |
251 | =head2 debug |
252 | |
253 | Causes SQL trace information to be emitted on C<debugfh> filehandle |
254 | (or C<STDERR> if C<debugfh> has not specifically been set). |
255 | |
256 | =head2 debugfh |
257 | |
258 | Sets or retrieves the filehandle used for trace/debug output. This |
259 | should be an IO::Handle compatible object (only the C<print> method is |
260 | used). Initially set to be STDERR - although see information on the |
261 | L<DBIX_CLASS_STORAGE_DBI_DEBUG> environment variable. |
262 | |
486ad69b |
263 | =head2 debugcb |
264 | |
265 | Sets a callback to be executed each time a statement is run; takes a sub |
266 | reference. Overrides debugfh. Callback is executed as $sub->($op, $info) |
267 | where $op is SELECT/INSERT/UPDATE/DELETE and $info is what would normally |
268 | be printed. |
