I am working on Android 2.3 Simulator.
I have some 5 unique categories...
I need to add these categories in my table....
I added it using primary key like this
Create table if not exists test (category integer primary key, value text) ;
But if i execute this query twice
insert into test(category, value) values(1,"0");
Then it is adding this twice
Even if i use unique like this
Create table if not exists test (category integer unique, value text) ;
Then also it is adding the row twice...
How to make a row unique?

dont add record manually ie for primary key, you can assign primary key as auto increment, let system will add record.
