JDBC：如何将对象列表传递到prepareStatement中，或者作为更好的选择

Question

I have a question about JDBC.

PreparedStatement preparedStatement = 
      dbConnection.prepareStatement(
             "SELECT userid, roleid, name from permission 
              where (userid, roleid) in (?)");

// assume I cannot update the above line, which is maintained by others

// now I just get a PreparedStatement and a list of object
Set<Pair<Integer, Integer>> idPair = ....

How can I execute the query with idPair variable?

PS: ( userid , roleid ) together are primary key for permission table

Thank you so much!

Answer 1

You can not.

You need to resort to plain SQL with iteration and filtering.

This is not JDBC specific, but AFAIK universal to most drivers.
