Without a view (but with a trigger) and certainly open to improvement
(9 is the
MAX_ENTRIES parameter):
CREATE TABLE "log" (
"id" INTEGER NOT NULL PRIMARY KEY ON CONFLICT REPLACE AUTOINCREMENT,
"seq" INTEGER CONSTRAINT "ix1Seq" UNIQUE ON CONFLICT REPLACE,
"data" CHAR);
CREATE TRIGGER "trInsLog"
AFTER INSERT
ON "log"
BEGIN
update log set seq = id % 9 where id=(select max(id) from log);
END;
insert into log (data) values ('a');
