RIGHE DOVE OTTIENE I DATI

com1 = ['SELECT 	' str_data, ' '];
com2 = ['FROM 	' str_container, ' '];
if length(where)>2
    com3 = ['WHERE 	' where, ' '];
    com4 = ['ORDER BY 	' str_order, ' '];
    curs = exec(conn, [com1 com2 com3 com4]);
else
    com3 = ['ORDER BY 	' str_order, ' '];
    curs = exec(conn, [com1 com2 com3]);
end

curs = fetch(curs);
close(curs);

COSA SONO com1, com2, com3 e conn? Ecco qui:

conn =
