Hi
If I have a table with a couple of indexed varchar fields e.g:
CREATE TABLE t (id INT, a VARCHAR(20), b VARCHAR(20)...);
CREATE INDEX ia ON t(a);
CREATE INDEX ib ON t(b);
then will the sqlite query optimizer use these indices in these SELECT's:
1. SELECT * FROM t WHERE a LIKE 'M%';
2.
No, we are actually filling in the parameter with a valid integer value. I
was just trying to say it was a parameter.

SQLite is built into the Mac. Apple uses it for many
of the applications that come on the mac, such as the
email reader and safari.
Just open up a terminal window and type "sqlite3" and
you will see.

SQLite just works on Mac OS X. If you have the Mac OS X Developer
Tools intalled, you can just compile the normal SQLite source distro

SQLite is used on the Mac natively - for example Mail.app uses a
SQLite DB to keep its message data straight.
Try the sqlite3 shell command.

Not without querying.
But you could do something like this:
CREATE TABLE t1(a PRIMARY KEY, b, c);
insert into t1
select 7, 'foo', 'bar' where not exists (
select null from t1 where a=7);
which is similar to:

Hi

2.
You can put a Primary Key (unique index) on the table.
Then when inserting a duplicate, an error will be generated.
Then test for the error.
Or if you want the new row to overwrite the original use insert or replace
If you goal is to keep the existing use insert or ignore.

If you have uniquness constaints in place that prevent insertion of the
duplicate row, your statement will fail with SQLITE_CONSTRAINT error.
Igor tandetnik
If you can, define one of the data entries in your table (Schema
defination) as "unique" when you create the table. The engine will then
set an error condition (call the callback function) and this should
prevent you from entering duplicate data and hence duplicate rows.

We are using precompiled insert statements and bind the parameters.
The inserts were done in a transaction that is committed and reopened every
1000 iterations.
