Przykład 1. A fetch row example


<?php
$conn = ovrimos_connect("remote.host", "8001", "admin", "password");
if ($conn != 0) {
    echo "Connection ok!";
    $res=ovrimos_exec($conn, "select table_id, table_name from sys.tables");
    if ($res != 0) {
        echo "Statement ok!";
        if (ovrimos_fetch_row($res, "First")) {
            $table_id = ovrimos_result($res, 1);
            $table_name = ovrimos_result($res, 2);
            echo "table_id=" . $table_id . ", table_name=" . $table_name . "\n";
            if (ovrimos_fetch_row($res, "Next")) {
                $table_id = ovrimos_result($res, "table_id");
                $table_name = ovrimos_result($res, "table_name");
                echo "table_id=" . $table_id . ", table_name=" . $table_name . "\n";
            } else {
                echo "Next: error\n";
            }
        } else {
            echo "First: error\n";
        }
        ovrimos_free_result($res);
    }
    ovrimos_close($conn);
}
?>

This will fetch a row and print the result.
