Beispiele
Beispiel #1 Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}$query = "SELECT name, cno from hotel.customer ORDER BY cno";if (
$result = $maxdb->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
/* get fieldpointer offset */
$currentfield = $result->current_field;
printf("Column %d:\n", $currentfield);
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
printf("max. Len: %d\n", $finfo->max_length);
printf("Flags: %d\n", $finfo->flags);
printf("Type: %d\n\n", $finfo->type);
}
$result->close();
}/* close connection */
$maxdb->close();
?>Beispiel #2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}$query = "SELECT name, cno from hotel.customer ORDER BY cno";if (
$result = maxdb_query($link, $query)) {
/* Get field information for all fields */
while ($finfo = maxdb_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = maxdb_field_tell($result);
printf("Column %d:\n", $currentfield);
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
printf("max. Len: %d\n", $finfo->max_length);
printf("Flags: %d\n", $finfo->flags);
printf("Type: %d\n\n", $finfo->type);
}
maxdb_free_result($result);
}/* close connection */
maxdb_close($link);
?>Das oben gezeigte Beispiel erzeugteine ähnliche Ausgabe wie:
Column 1:Name: NAMETable:max. Len: 10Flags: -1Type: 2Column 2:Name: CNOTable:max. Len: 4Flags: -1Type: 0
