I tried to implement something like this and it seems it works (very easy for anyone familiar with virtual tables). The table itself doesn't need any init data (and doesn't even contain) and absorbs data from the query itself So finally the db/program that wants to use it creates it with something like CREATE VIRTUAL TABLE cmlist Using vtcommalist Table format CREATE TABLE [xxx] ([CommaList] TEXT, [Value] TEXT) And example query is SELECT value FROM cmlist WHERE commalist='45,56,78,125' So we finally got "45" "56" "78" "125" Internally my xFilter just stores the commalist from the query and uses it for First/Next The only problem with this approach is that rowid makes sense only for queries mentioned. So SELECT rowid FROM cmlist can't return valid results I wonder can it be a problem for complex queries when sqlite decides itself what to query and maybe relies on the correctness of rowid.
