stringmaxdb->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.
Возвращаемые значения
A string that describes the error. An empty string if no error occurred.
