I'm not sure if you are looking to make a entry unique, or determine the order
in which the entries occurred. In either case, be aware - time can go
*backwards* on a system, especially if it is being syncd to an outside source
such as with NTP.

Would this be a better design ?
That would be definitely a better design at least because you will be
able to keep only one prepared statement where one of bindings will be
your entity id. Also you will be able to add more types of entities
without changing database schema. Just don't forget

I implemented a custom function that returns a comma separated list of

Hi all,
I'm in the design phase of an application with SQLite backend. The SQLite
file will hold a table of about 20K records initially, and a few several
other small tables. About 75% of the records in the large table will have
binary data associated with it. My main question is which one of

Hi,
I have a table called PEOPLE with 2 fiels:
NAME à TEXT 40
BIRTH à DATETIME
With some records
I want to filter all people with BIRTH = 1946, I’m trying this:
SELECT * FROM PEOPLE WHERE YEAR(PEOPLE.BIRTH)=’1946’;
There are several people in this year, but recordset all time returns 0
Did you try to put 1946 without quotes?

Maybe. Also there's a question when I wanted to ask in the first
letter too: where did you get function year() from? I don't see it in
http://www.sqlite.org/lang_datefunc.html and my sqlite3 doesn't see it
too:
sqlite select year(date('now'));
SQL error: no such function: year
Maybe it's SQLite

Is it possible to tell SQLite to use a specified index?
I know you can use the + to excludes fields being used in an index,
but this doesn't help me in this particular case. I remember a

but couldn't find it anywhere.

I understand that SQLite lets you use arbitrary names for column types,
and all that's significant is a few substrings like INT, CHAR, and
BLOB. But what's the common practice? Do you declare everything as
INTEGER, TEXT, BLOB, REAL, or NUMERIC for a one-to-one match with the
