JDBC: in set condition: can I pass a set as single param?

Question

In JDBC I can use question marks for query parameters, like this:

\"SELECT * FROM users WHERE login = ?\"

and then

ps.setSt

Look here for an overview of available options. As far as I can tell you, everyone is dynamically generating the necessary number of placeholder characters (with some optimizations).

There's a setArray method in PreparedStatement, but sometimes using it is not feasible. You might give it a try though.

If Spring's JDBCTemplate is an option, you could use automatic collection expansion as described here.
