Hello all,

I am using SQLite on a mobile device.

I have this one table which has only one field, but I need to search in 
the table very quickly.
When creating an index on this field the size of the database is doubled 
- which makes sense.

However, is there some way to implement this scenario more efficiently 
using SQLite ?
It seems like I am storing all data twice and space on mobile devices is 
rather limited.

--
My table:

CREATE TABLE [ART] ([artnr] VARCHAR(10) NOT NULL);
CREATE UNIQUE INDEX [IDX_ART] ON [ART]([artikelnr]  ASC);

or

CREATE TABLE [ART] ([artnr] VARCHAR(10) PRIMARY KEY NOT NULL);

Are both identical in terms of size.

Thanks for your help.
