The metaColumns method returns an array of adoFieldObject object that represents the attributes of the columns of a specified table.

$m = $db->metaColumns('my_table');
 
print_r($m);

adoFieldObject Object
(
  [name] => actno
  [max_length] => 8
  [type] => INT
)

adoFieldObject Object
(
  [name] => actname
  [max_length] => 30
  [type] => VARCHAR
)

Note that the type of the data returned is the actualType. In order to retrieve the metaType , the value must be passed to:

$db->metaType($object->type);

For example, in the example above, the actname field is of a type VARCHAR . If we pass this to metaType(), it returns the value C

This method returns just the column names from the table.
