PHP マニュアル: Return the ID generated for the last updated AUTO

説明

string cubrid_insert_id(resource $conn_identifier = ?)

The cubrid_insert_id function retrieves the ID generated for the AUTO_INCREMENT column which is updated by the previous INSERT query. It returns 0 if the previous query does not generate new rows, or FALSE on failure.

注意:
CUBRID supports AUTO_INCREMENT for more than one columns in a table. In most cases, there will be a single AUTO_INCREMENT column in a table. If there are multiple AUTO_INCREMENT columns, this function should not be used even if it will return a value.

パラメータ

conn_identifier: The connection identifier previously obtained by a call to cubrid_connect.

戻り値

A string representing the ID generated for an AUTO_INCREMENT column by the previous query, on success.

0, if the previous query does not generate new rows.

false on failure.

例

例1 cubrid_insert_id example

<?php
$conn = cubrid_connect("localhost", 33000, "demodb");

@cubrid_execute($conn, "DROP TABLE cubrid_test");
cubrid_execute($conn, "CREATE TABLE cubrid_test (d int AUTO_INCREMENT(1, 2), t varchar)");

for ($i = 0; $i < 10; $i++) {
    cubrid_execute($conn, "INSERT INTO cubrid_test(t) VALUES('cubrid_test')");
}

$id = cubrid_insert_id();
var_dump($id);

cubrid_disconnect($conn);
?>

上の例の出力は以下となります。

string(2) "19"
