This is technically possible with a workaround, but very bad practice.

String sql = "IF ? = 99\n";
sql += "SELECT * FROM first_table\n";
sql += "ELSE\n";
sql += "SELECT * FROM second_table";
PreparedStatement ps = con.prepareStatement(sql);

And then when you want to select from first_table you set the parameter with

ps.setInt(1, 99);

Or if not, you set it to something else.
