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