Exemplo #1 List primary Keys of a Column
<?php
$conn = odbc_connect($dsn, $user, $pass);
$primarykeys = odbc_primarykeys($conn, 'TutorialDB', 'dbo', 'TEST');
while (($row = odbc_fetch_array($primarykeys))) {
print_r($row);
break; // further rows omitted for brevity
}
?>
O exemplo acima produzirá algo semelhante a:
Array ( [TABLE_CAT] => TutorialDB [TABLE_SCHEM] => dbo [TABLE_NAME] => TEST [COLUMN_NAME] => id [KEY_SEQ] => 1 [PK_NAME] => PK__TEST__3213E83FE141F843 )
