[graciano]

Hi,
After connectig to a database i whant to check if a database is already created and with a specific structure.
As an example:mysql> describe Teste;

+---------+---------+------+-----+---------+-------+
| Field   | Type    | Null | Key | Default | Extra |
+---------+---------+------+-----+---------+-------+
| field01 | int(11) | NO   | PRI | NULL    |       | 
| field02 | int(11) | YES  |     | NULL    |       | 
+---------+---------+------+-----+---------+-------+

+---------+---------+------+-----+---------+-------+
| Field   | Type    | Null | Key | Default | Extra |
+---------+---------+------+-----+---------+-------+
| field01 | int(11) | NO   | PRI | NULL    |       | 
| field02 | int(11) | YES  |     | NULL    |       |
