    PrepardStatements don’t support variable numbers of conditions. What some frameworks do, is they cache each PreparedStatement in a Map where the key is the query.

    So each time you want to run a query, you need to build the string to create the PreparedStatement, check if you have it in the map (and reuse it) or create a new one, and add it to the map.
