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

### Description

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.

### Parameters

`link`

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

### Return Values

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