slight misunderstanding with sqlite database in android
<p>i created a database with 6 columns and i have a create and update method in my class that takes 6 parameters/arguments which represent these columns. my problem is that, anytime i try to update or create the database without using all 6 arguments (setting some to null), i get an  error "constraint failed". this is most particular with the update method. </p>

<p>any ideas how i can get around this? because sometimes i don't want to fill all columns. I have removed the "text not null" constraint when creating the database.  Thank you.</p>
