Answer 1

You need to fill parameter in PreparedStatement

preparedStatement.setLong(1, someIdentifier)

Answer 2

It is maybe because you didn't set parameter for your request:

SELECT * FROM mydatabase WHERE TickerID= ?

You have to add:

preparedStatement.setString(1, "youUserIdValue");

Before to execute the query.

You can also use named parameter:

preparedStatement = connect
        .prepareStatement("SELECT * FROM mydatabase "
                    + " WHERE TickerID=:userID");
preparedStatement.setString("userID", "youUserIdValue");
