|
|
*
|
|
* You only need to clone the global database object $GLOBALS['egw']->db if:
|
|
* - you use the old methods f(), next_record(), row(), num_fields(), num_rows()
|
|
* - you access an application table (non phpgwapi) and you want to call set_app()
|
|
*
|
|
* Otherwise you can simply use $GLOBALS['egw']->db or a reference to it.
|
|
*
|
|
* Avoiding next_record() or row() can be done by looping with the recordset returned by query() or select():
