Hi Alex,
Thanks very much for helping.
So far I've done the mods to the database rel you suggested and I have this
query:
(? (select (@A) ((year +Agenda 2019) (week +Agenda 32) (same 2019 @A year)
(same 32 @A week)) )
which works and gives me results like these:
@A = {1643}
...
@A = {1731}
Now, is there any way to get all those results in a list like this:
( {1643} ... {1731})
in order to print them in a table with the "tab" function like:
...(with This (tab Fmt (: year) (: week) (: status)))....
Regards,
Eric

Hi Eric,

'+Idx' is not suitable for numbers, as it builds an index of substrings, not of
the numerical values. '+Ref' would be the best here.
Also, (+date) must be (+Date) (or better (+Ref +Date)).

This is fine (if the indexes are fixed as above). In addition you need also
filter clauses (before the 'show'):
(same 2019 @A year)
(same 32 @A week)
