Question: in a DBGrid, you can add one or more columns that are not
part of the datasource? In order to use them as variables of support?
If you explain to me how? You can also change the order of the columns
from code? Without going to work on the query? thanks

Double clicking on the DBGrid in development will bring up a display
where you can add, remove, edit title, and change the display order of
columns. Have never tried to display something that was not in the
query.

You will need to use a datasource anyway. What I usually do in these
cases is use a in-memory dataset like TMemDataSet or TRxMemoryData
copy the data from a query dataset and then add the fields
programatically.
