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

Описание

string ingres_error ([ resource $link ] )

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.

Список параметров

The connection link identifier. If not specified, the last opened link is used.

Возвращаемые значения
