cubrid_insert_id
(PECL CUBRID >= 8.3.0)
cubrid_insert_id — Return the ID generated for the last updated AUTO_INCREMENT column
說明
$conn_identifier = ?): stringThe 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.
返回值
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.

範例
示例 #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);
?>
以上例程會輸出：
string(2) "19"
