226 | =head1 NAME |
227 | |
228 | DBIx::Class::Storage::DBI - DBI storage handler |
229 | |
230 | =head1 SYNOPSIS |
231 | |
232 | =head1 DESCRIPTION |
233 | |
234 | This class represents the connection to the database |
235 | |
236 | =head1 METHODS |
237 | |
8b445e33 |
238 | =cut |
239 | |
d7c4c15c |
240 | =head2 on_connect_do |
241 | |
242 | Executes the sql statements given as a listref on every db connect. |
243 | |
92b858c9 |
244 | =head2 debug |
245 | |
246 | Causes SQL trace information to be emitted on C<debugfh> filehandle |
247 | (or C<STDERR> if C<debugfh> has not specifically been set). |
248 | |
249 | =head2 debugfh |
250 | |
251 | Sets or retrieves the filehandle used for trace/debug output. This |
252 | should be an IO::Handle compatible object (only the C<print> method is |
253 | used). Initially set to be STDERR - although see information on the |
254 | L<DBIX_CLASS_STORAGE_DBI_DEBUG> environment variable. |
255 | |
486ad69b |
256 | =head2 debugcb |
257 | |
258 | Sets a callback to be executed each time a statement is run; takes a sub |
259 | reference. Overrides debugfh. Callback is executed as $sub->($op, $info) |
260 | where $op is SELECT/INSERT/UPDATE/DELETE and $info is what would normally |
261 | be printed. |
