That is what I use now, together with the select as Hick mentioned. An other version I played with is two indexes, one unique on (id, ts_from) to find the last version if eol is not null and one unique on (id, ts_eol) where eol = null to find the current active version of id.
Beware that in almost all contexts, null != null. Hence your condition eol = null will never be satisfied.
Use isnull instead. JcD _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
