Nowadays using a JSON array would be an obvious answer. Since this is an old but still relevant question I produced a short example. JSON functions are available since mySQL 5.7.x / MariaDB 10.2.3.

For this to be successful, the DBMS must support parameter arrays natively, but MySQL does not have this feature. When the DBMS does not support parameter arrays, an ODBC driver can simulate array processing by executing an SQL statement once for each set of parameter values. And this is what the DataDirect MySQL driver actually does.
