Deliver Value to TV

Hello,

I have the following question:

I created a TV to show a database query in a DataGrid-Widget:

@SELECT name, vorname, te_datum, te_zeit
FROM mitglieder, teilnahmen, termine
WHERE mit_nr=te_spieler
AND te_turnier=115
AND t_id=te_turnier
ORDER BY te_datum, te_zeit

Because of "te_turnier=115" only a specific datarecord is shown.
Now I want to change the Select like "te_turnier=$xy".
But:
How can I deliver the value xy to the TV?
Is it possible to call the TV like [*TV-Name &paramA=’1’*] ?
If it is possible, how do I have to change the Select?
Or is there another easy way?

Thanx for your help
