string $maxdb->error;
The maxdb_error() function is identical to the corresponding
maxdb_errno() function in every way, except instead of returning
an integer error code the maxdb_error() function will return
a string representation of the last error to occur for the database connection
represented by the link parameter. If no error has occurred,
this function will return an empty string.
반환값
A string that describes the error. An empty string if no error occurred.
