Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* Create table doesn't return a resultset */ if ($maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) { printf("Table mycity successfully created. "); } /* Select queries return a resultset */ if ($result = $maxdb->query("SELECT name FROM hotel.city")) { printf("Select returned %d rows. ", $result->num_rows); /* free result set */ $result->close(); } /* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */ if ($result = $maxdb->query("SELECT * FROM hotel.city", MAXDB_USE_RESULT)) { $result->close(); } $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* Create table doesn't return a resultset */ if (maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) { printf("Table mycity successfully created. "); } /* Select queries return a resultset */ if ($result = maxdb_query($link, "SELECT name FROM hotel.city")) { printf("Select returned %d rows. ", maxdb_num_rows($result)); /* free result set */ maxdb_free_result($result); } /* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */ if ($result = maxdb_query($link, "SELECT * FROM hotel.city", MAXDB_USE_RESULT)) { maxdb_free_result($result); } maxdb_close($link); ?> The above example will output something similar to: Table mycity successfully created. Select returned 25 rows. SEE ALSO
