The metaColumns method returns an array of adoFieldObject objects that represent 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

Some drivers return an extended set of attributes that represent DBMS specific functionality. If you are writing portable applications you should not rely on these attributes to be available across all databases.

This method returns just the column names from the table.
