I have this code to delete a table, in the same way, I have two more to insert data or delete them and they are barbarous, but this delete table is impossible, I do not know what happens, I used even with Statement and nothing.
PreparedStatement pst;
String borrarTablaSql= "drop table if exists empleados_?";
pst= con.prepareStatement(borrarTablaSql);
pst.setString(1, usuarioAdmin);
pst.executeUpdate();
pst.close();
