What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



pg_getlastoid — Displays the object ID of the last INSERT.


int pg_getlastoid(result);
int result: Result identifier


Last object ID; FALSE on error


Returns the object identifier (OID) from the pg_exec() function. OIDs are similar to auto-increment fields except that they're maintained internally by the database. To get last the inserted ID in a table, use this function or retrieve the current value of the sequence used to populate primary key - if it exists. This function only works if the last command sent was an INSERT SQL statement.


Example 1041. Retrieve record OID

$db = pg_connect("host=dbserver dbname=db user=dbuser password=dbpasswd");
$result = pg_exec($db,"IBSERT INTO table_one ('first') VALUES ('John')");
// get insert OID
$oid = pg_getlastoid();
$result = pg_exec($db, "SELECT id FROM table_one WHERE oid=$oid");
$id = pg_result($result, 0, "id");
// write into next table
$result = pg_exec($db, "INSERT INTO table_two (one_id) VALUES ($id");
