It gets evaluated whenever the SELECT runs. The value isn't cached anywhere. The only difference between a deterministic and a regular function currently (AFAIK) is that the former can be used in a CREATE INDEX statement. This allows a query that makes an equivalent call to use the index. TL;DR: it's how you can do efficient queries on derived values like JSON properties. —Jens _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
