pg_last_oidReturns the last row's OID Description
string pg_last_oid
( resource
$result
)pg_last_oid is used to retrieve the OID assigned to an inserted row. OID field became an optional field from PostgreSQL 7.2 and will not be present by default in PostgreSQL 8.1. When the OID field is not present in a table, the programmer must use pg_result_status to check for successful insertion. To get the value of a SERIAL field in an inserted row, it is necessary to use the PostgreSQL CURRVAL function, naming the sequence whose last value is required. If the name of the sequence is unknown, the pg_get_serial_sequence PostgreSQL 8.0 function is necessary. PostgreSQL 8.1 has a function LASTVAL that returns the value of the most recently used sequence in the session. This avoids the need for naming the sequence, table or column altogether.
