I'd like to perform a SMW query based on current year and month information. The problem: It seems that I need to feed values into the SMW ask section in a non-static way as I cannot hard code these values. How can I do that and perform such a query?
Use {{#time:}}
parser function. Date formats that SMW will understand are given here. Below, I used d.m.Y
and d xg Y
that will definitely work in a wiki in Russian.
Use Unix format (U
, the number of seconds since Unix era; use @
to convert it back to date object) for date arithmetics.
Examples (assuming that you have the special property Creation date activated):
<!-- Pages created today -->
{{#ask:
[[Creation date::>={{#time:d.m.Y}}]]
}}
<!-- Pages created yesterday -->
{{#ask:
[[Creation date::>={{#time:d xg Y|@{{#expr:{{#time:U}}-86400}}}}]]
[[Creation date::<{{#time:d xg Y}}]]
}}
