The PIVOT command is not standard SQL command, it is supported only by some DBMS, SQLite and MySQL are not among them.

But you can make a similar view of the data using a script that will create a table view with the desired number of columns and rows.
This is not often ordered, I don’t have a ready-made simple example. All I can say is that you will need three SQL queries: 1) get a list of headers for rows 2) get a list of headers for columns 3) get data.

Key methods:

1) add Column for Row Names

  try
     Grid.Columns.Add(TNxTextColumn);
   except
   end;
  Grid.Columns[0].Width := 40;
  Grid.FixedCols := 1;
  Grid.Columns[0].Color := clbtnFace;

2) add a column for data

    
    try
      Grid.Columns.Add(TNxTextColumn);
    except
    end;
    Grid.Columns[Grid.Columns.count-1].Header.Caption := ColData.FieldByName('name').asString;
    Grid.Columns[Grid.Columns.count-1].Color := clWhite;
    Grid.Columns[Grid.Columns.count-1].Width := 40;

3) add a row

    Grid.AddRow;
    Grid.Cells[0, Grid.RowCount-1] := RowData.FieldByName('name').asString;

4) fill the cell with data.

       Grid.Cells[col, row] := CellData;
