Let the database be: Create table if not exists maintable (rowid INTEGER PRIMARY KEY, puid INTEGER) Create Unique Index if not exists puididx on maintable (puid)
Assume a query "select rowid from maintable where puid = X OR puid = Y or puid = Z" How will this query work internally? 1 Will it first check the index table for puid = X and get the rowid, then followed by checking the index table for puid = Y, then puid =Z. 2 Will it first check each row puid and match it with X then Y then Z and then move to the second row in maintable? (Without referring to the index table) 3 Will it first check for puid = X in the maintable then check for puid = Y in the maintable and then for puid =z? (Without referring to the index table) 4 Any other way Regards, Phani
