QSqlQuery and bad performance!

[mismael85]

i created an index but the query still slow and here are the schema

CREATE TABLE b11430
-- This table created by SQLite2008 Pro Enterprise Manager
-- Osen Kusnadi - http://www.osenxpsuite.net
-- Created date: 2010-09-24 19:47:33
(
       id INTEGER,
       nass TEXT,
       part INTEGER,
       page INTEGER
);
CREATE UNIQUE INDEX idx ON b11430(id);

CREATE TABLE b11430
-- This table created by SQLite2008 Pro Enterprise Manager
-- Osen Kusnadi - http://www.osenxpsuite.net

(
       id INTEGER,
       nass TEXT,
       part INTEGER,
       page INTEGER
);
CREATE UNIQUE INDEX idx ON b11430(id);

To copy to clipboard, switch view to plain text mode 

is there a solution?
