Android Content Provider SQL Where Query

Question

I have created a content provider in my android application, now I wish to update a specific row but im unsure how to procede.

My table consists of 3 columns, ID(Key), name and score.

I wish to update the score to 10 if the player's name is 'John'. I understand it should be something similar to below but im not sure what to use for the third paramter.

database.update(TABLE, 10, newWhere, whereArgs);

Answer 1

Assuming your name column is called name and your score column is score , you would want something like

ContentValues cv = new ContentValues();
cv.put(`score`, 10);
database.update(TABLE, cv, "name = ?", new String[]{"John"});
