SYNOPSIS
       string ingres_errsqlstate ([resource  $link])

DESCRIPTION
	Returns a string containing the last SQLSTATE, or NULL if no error has occurred.

	If  a  $link  resource	is  passed  to	ingres_errsqlstate(3), it returns the last error recorded for the link. If no link is passed, then
       ingres_errsqlstate(3) returns the last error reported using the default link.

	The function, ingres_errsqlstate(3), should always be  called  after  executing  any  database	query.	Calling  another  function  before
       ingres_errsqlstate(3) is called will reset or change any error message from the last Ingres function call.

		- The connection link identifier

RETURN VALUES
	Returns a string containing the last SQLSTATE, or NULL if no error has occurred.
