SQL Types

Question

Hi,
I am trying to retrieve the data type of my column in the ResultSetMetaData but i don�t know how.
This is my code:
     for(int x=0;x<c;x++){
          out.print("INSERT INTO "+tabela+" (");
          for(int z=0;z<meta.getColumnCount();z++){
               out.print(meta.getColumnName(z+1));
               if(z!=meta.getColumnCount()-1)
                    out.print(",");
          out.print(")");
          out.print(" VALUES (");
          for(int y=0;y<meta.getColumnCount();y++){
               out.print(meta.getColumnType(y+1)); //This is what i want to know.
                        out.print(dados[x][y]);
               if(y!=meta.getColumnCount()-1)
                    out.print(",");
          out.print(")");
          out.print(";");
          out.print("<br>");
     }
