Question

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?

Answer 1

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