232 | |
233 | DBIx::Class::Storage::DBI - DBI storage handler |
234 | |
235 | =head1 SYNOPSIS |
236 | |
237 | =head1 DESCRIPTION |
238 | |
239 | This class represents the connection to the database |
240 | |
241 | =head1 METHODS |
242 | |
8b445e33 |
243 | =cut |
244 | |
d7c4c15c |
245 | =head2 on_connect_do |
246 | |
247 | Executes the sql statements given as a listref on every db connect. |
248 | |
92b858c9 |
249 | =head2 debug |
250 | |
251 | Causes SQL trace information to be emitted on C<debugfh> filehandle |
252 | (or C<STDERR> if C<debugfh> has not specifically been set). |
253 | |
254 | =head2 debugfh |
255 | |
256 | Sets or retrieves the filehandle used for trace/debug output. This |
257 | should be an IO::Handle compatible object (only the C<print> method is |
258 | used). Initially set to be STDERR - although see information on the |
259 | L<DBIX_CLASS_STORAGE_DBI_DEBUG> environment variable. |
260 | |
486ad69b |
261 | =head2 debugcb |
262 | |
263 | Sets a callback to be executed each time a statement is run; takes a sub |
264 | reference. Overrides debugfh. Callback is executed as $sub->($op, $info) |
265 | where $op is SELECT/INSERT/UPDATE/DELETE and $info is what would normally |
266 | be printed. |
