Duplicate entry '416' for key 1
The answer is in the SQL statement you included in your question: the statement tries to insert the value 416 to the field “id_termo”, but the table already contains a record with the same id_termo. id_termo is the primary key for the table (at least, I guess it is), so it must be unique.
Possible causes:
– you forgot to declare id_termo field as primary key in Access
– the Access db is corrupt (allowed the insertion of the same value more than once) – a slim chance
– you try to import records that already exist in the MySql db, try writing your own import query instead of copying the whole table
