(no version information, might be only in CVS)

maxdb_insert_id

(no version information, might be only in CVS)

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

Syntax

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.
