How to update android sqlite database database column value to null using ContentValues?

Question

For example, I want to do the following to upgrade a database.

Is there a constant that I can use instead of null that will not compile if I use it like:

 ContentValues args = new ContentValues(); args.put(KEY_RISK_AMOUNT, null); // what constant do I use instead of null? 

Answer 1

Use ContentValues.putNull(java.lang.String) :

 ContentValues args = new ContentValues(); args.putNull(KEY_RISK_AMOUNT);
