ingres_error — Get a meaningful error message for the last error generated
Описание
string ingres_error
([ resource $link
] )
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.
