ingres_error — Get a meaningful error message for the last error generated

Description

ingres_error ([ resource $link ] ) : string

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

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

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