| ) | [inline] |
Binds an actual input value for an placeholder in the SQL statement.
All binding is done by value! this means the passed data are copied to internal storage. Chaning your original copy of your data after passing it to bind() is therefore safe.
| pos | The position indicator. The number of placeholder (?) in the SQL string. Counted from the left starting at 0. | |
| val | the actual value. | |
| nul | NULL inidcator, if set to yes the actual value to be bound will be NULL. Please note that you still need to provide a valid value! |
Reimplemented from fatalmind::SQL::BindInterface.
| virtual void fatalmind::Command< PT >::execute | ( | typename PT::resource_t & | rr | ) | [pure virtual, inherited] |
The execute method is the one which actually carries out the work.
This method gets called by ResourcePool with a (valid) plain resource which was obtained from the pool.
On normal execution (no exception) the resource will be free()ed, on abnormal execution (exception) the resource will be failed. If you need to throw an functional exception which should not cause failing of the resource, derive this exception from NoFailoverException.
