Beispiele
Beispiel #1 List Tables in a Catalog
<?php
$conn = odbc_connect($dsn, $user, $pass);
$tables = odbc_tables($conn, 'SalesOrders', 'dbo', '%', 'TABLE');
while (($row = odbc_fetch_array($tables))) {
print_r($row);
break; // further rows omitted for brevity
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Array ( [TABLE_CAT] => SalesOrders [TABLE_SCHEM] => dbo [TABLE_NAME] => Orders [TABLE_TYPE] => TABLE [REMARKS] => )
