What does 'access violation' mean in the context of MySQL Error 1064 (SQLSTATE 42000)?

While primarily known as a syntax error, the 'access violation' part of Error 1064 (SQLSTATE 42000) can also refer to situations where the user executing the query lacks the necessary privileges to perform the requested operation, even if the syntax itself is technically correct. For instance, attempting to drop a table without the DROP privilege might sometimes manifest with this error code.
