SQLite 3.7.5. I have a table (13 columns with 1 primary key, 1 index on a date column, 1 UNIQUE-constraint on two columns). I insert ~1300000 rows, 1000 at a time (transaction-wise). I close the database, reopen it and immediately perform a COUNT-operation: SELECT COUNT(ItemID) FROM Items;
This takes around 40 seconds the first time! WHY?! I believe the value is somehow cached inside the database after the above call. The table used: CREATE TABLE IF NOT EXISTS Item ( ItemID INTEGER PRIMARY KEY, A INTEGER NOT NULL, B INTEGER NOT NULL, C INTEGER NOT NULL, D INTEGER NOT NULL, E INTEGER NOT NULL, F INTEGER NOT NULL, G INTEGER NOT NULL, H DATE NOT NULL, I CHAR(3) NOT NULL, J INTEGER NOT NULL, K INTEGER NOT NULL, L INTEGER NOT NULL, UNIQUE (B, A) ); CREATE INDEX IF NOT EXISTS Item_H_Index ON Item (H); _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
