ImageAbout PostgreSQL
One of the leading Open Source database engines available today. With features more competitive to the top tier commercial vendors than other Open Source alternatives, the platform offers a wide range of features and abilities. Adding to that value is a more Mac friendly packaging that eschews the need to be a developer or experienced Unix system administrator to set up.

Run the installer, start and stop the server from System Preferences and use graphical tools to create users, databases and run queries. For automation purposes, there are Automator actions included in the package, along with JDBC libraries, and a ready to use framework that enables Cocoa developers to quickly access and consume PostgreSQL data.

LEARN ABOUT PHP

pg_last_oid

PG_LAST_OID(3)															    PG_LAST_OID(3)

pg_last_oid - Returns the last row's OID

SYNOPSIS

       string pg_last_oid (resource  $result)

DESCRIPTION

       pg_last_oid(3) 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(3) 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.

       Note

	       This function used to be called pg_getlastoid(3).

PARAMETERS

	      o $result
		- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).

RETURN VALUES

	A string containing the OID assigned to the most recently inserted row in the specified $connection, or FALSE on  error  or  no  available
       OID.

EXAMPLES

       Example #1

	      pg_last_oid(3) example

	      <?php
		// Connect to the database
		pg_connect("dbname=mark host=localhost");

		// Create a sample table
		pg_query("CREATE TABLE test (a INTEGER) WITH OIDS");

		// Insert some data into it
		$res = pg_query("INSERT INTO test VALUES (1)");

		$oid = pg_last_oid($res);
	      ?>
