Could anybody tell me if I can use INSERT function in processing with MySQL?

I use simpliest code:

1. import de.bezier.data.sql.*;
   
   MySQL msql;
   
   void setup()
   {
       size( 100, 100 );
      
       // this example assumes that you are running the
       // mysql server locally (on "localhost").
       //
      
       // replace --username--, --password-- with your mysql-account.
       //
       String user     = "test";
       String pass     = "666666";
      
       String database = "test";
   
       msql = new MySQL( this, "localhost", database, user, pass );
      
       if ( msql.connect() )
       {
           msql.query( "SELECT COUNT(*) FROM simple" );                                   //Here is OK.
           msql.next();
           println( "number of rows: " + msql.getInt(1) );                                         
   //        msql.query( "INSERT INTO `test`.`simple` (`one`) VALUES ('2');" );         //Error..
    msql.query( "INSERT INTO simple (one) VALUES (2);" );                               //Error too..
          
          
       }
       else
       {
           // connection failed !
       }
   }
   
   void draw()
   {
       // i know this is not really a visual sketch ...
   }

type of column "one" is INT. How should i write correctly to insert some numbers, and variables????

Because I have this:

SQL.query(): java.sql.SQLException.

java.sql.SQLException: Can not issue data manipulation statements with executeQuery().
