# maxdb_insert_id

(PECL)

maxdb_insert_id

(no version information, might be only in CVS)

maxdb->insert_id -- Returns the auto generated id used in the last query

## Description

Procedural style:

mixed maxdb_insert_id ( resource link )

Object oriented style (property):

class maxdb {
mixed insert_id
}

The maxdb_insert_id() function returns the ID generated by a query on a table with a column having the DEFAULT SERIAL attribute. If the last query wasn't an INSERT or UPDATE statement or if the modified table does not have a column with the DEFAULT SERIAL attribute, this function will return zero.

## Return Values

The value of the `DEFAULT SERIAL` field that was updated by the previous query. Returns zero if there was no previous query on the connection or if the query did not update an `DEFAULT_SERIAL` value.

> Note: If the number is greater than maximal int value, maxdb_insert_id() will return a string.

## Example

Example 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();
}
maxdb_report (MAXDB_REPORT_OFF);
$maxdb->query("DROP TABLE mycity");
maxdb_report (MAXDB_REPORT_ERROR);
$maxdb->query("CREATE TABLE mycity LIKE hotel.city");
$maxdb->query("ALTER TABLE mycity ADD id FIXED(11) DEFAULT SERIAL");
$query = "INSERT INTO mycity (zip,name,state) VALUES ('12203','Albany' ,'NY')";
$maxdb->query($query);
printf ("New Record has id %d.\n", $maxdb->insert_id);
/* drop table */
$maxdb->query("DROP TABLE mycity");
/* close connection */
$maxdb->close();
?>`

Example 2. Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
maxdb_report (MAXDB_REPORT_OFF);
maxdb_query($link,"DROP TABLE mycity");
maxdb_report (MAXDB_REPORT_ERROR);
maxdb_query($link, "CREATE TABLE mycity LIKE hotel.city");
maxdb_query($link, "ALTER TABLE mycity ADD id FIXED(11) DEFAULT SERIAL");
$query = "INSERT INTO mycity (zip,name,state) VALUES ('12203','Albany' ,'NY')";
maxdb_query($link, $query);
printf ("New Record has id %d.\n", maxdb_insert_id($link));
/* drop table */
maxdb_query($link, "DROP TABLE mycity");
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    New Record has id 1.
