We have something like: 

CREATE TABLE IF NOT EXISTS files
 (encoded_url varchar(65) UNIQUE NOT NULL primary key, modified DATETIME NOT NULL);

We want each time a new record is created to fill its modified field with now time automatically. Can we tall SQLite that it has to do such thing when we create a table or we should always insert nowwhen we fill in a row?

    You can use default CURRENT_TIMESTAMP in the column specification:

    sqlite> create table t (a datetime default CURRENT_TIMESTAMP, b text);
sqlite> insert into t(b) values ('hello');
sqlite> select * from t;
2011-10-16 17:29:54|hello
sqlite> insert into t(b) values ('hello again');
sqlite> select * from t;
2011-10-16 17:29:54|hello
2011-10-16 17:30:04|hello again

    There are other date/time options, documented in the column definition part of the create table syntax docs.
