Example #1 A db2_last_insert_id() example
The following example shows how to return the auto generated ID of last insert query that successfully executed on this connection.
<?php
$database = "SAMPLE";
$user = "db2inst1";
$password = "ibmdb2";
$conn = db2_connect($database, $user, $password);
if($conn) {
$createTable = "CREATE TABLE lastInsertID
(id integer GENERATED BY DEFAULT AS IDENTITY, name varchar(20))";
$insertTable = "INSERT INTO lastInsertID (name) VALUES ('Temp Name')";
$stmt = @db2_exec($conn, $createTable);
/* Checking for single row inserted. */
$stmt = db2_exec($conn, $insertTable);
$ret = db2_last_insert_id($conn);
if($ret) {
echo "Last Insert ID is : " . $ret . "\n";
} else {
echo "No Last insert ID.\n";
}
db2_close($conn);
}
else {
echo "Connection failed.";
}
?>
上例将输出：
Last Insert ID is : 1
