In order of preference
a) use FastBit software
b) normalize your database design to eliminate the array
c) use a BLOB of 125 bytes and user defined functions to operate on them
d) use a string of 1000 characters ('0' or '1') and the SUBSTR() function

Hello,
what is the best way to implement a Bitfield of size 1000 as a column in a
Table. I need to make queries to select all rows which have the nth bit set?The
bitfield describes for each day in about three years if a specific task needs
to be done.
There is some info here:

Good eye, thanks for reporting this.
Pointers on the stack or in static storage are pointer-aligned by default on
all of Apple's platforms.

I have worked with numeric data and also "keyword" data, i.e. a small number of
distinct keywords that appear in a string (or not).

Agreed. The default
Only one writer may be active at any one time. The other(s) will recieve an
error return status. You can either wait a while and retry this in your
application or set a busy timeout to handle the "usual" cases for you.

Hi all,
I am using System.Data.SQLite in my project.
I have two threads which are updating database simultaneously.
I get SQLite error(5): database is locked, System.Data.SQLite error.
Why is it so!. What could be the reason? Does System.Data.SQLite is not
thread safe?
Please help me out.

Hi all,
?
we have a product that uses SQLite. Because it was running very stable for
years, we are still using SQLite 3.7.17. Now we've seen on one of our
installations that the database has been corrupted, we saw that there was a
power failure around the time of the corruption. We tested power
Properly implemented virtual tables do support indexing, but you have to write
the code to support that yourself.
I have personally implemented an index based on the fastbit package which is
ideally suited to retrieving large data sets via equality and range constraints.
See

My primary keys are ROWIDs ("INTEGER PRIMARY KEY" actually)
None of the index was exploited for the order by, and the matched records
in table A are scattered in pages all over the database, so ordering them
in memory has a tendency to "replace" the
