function return 1 > 0 ??

[garnachito]

Hi guys

I'm working in some exercises and I saw this line in my book:

return db.update(DBTABLE, args, KEY_ID + "=" + id, null) > 0;

This method returns the number of rows affected, in this particular case it will always return 1 or 0, but I don't know what's the meaning of "> 0" at the end of the line

Can you help me to understand this ?

Thanks!

That line is likely part of a method that returns a boolean, right? So what will the above statement return if db.update(...) returns 1? What about if db.update(...) returns 0, what does the method that contains the line above return?

This is the entire function

public boolean updateUser(long id, String name, String pass){
			ContentValues args = new ContentValues();
			args.put(KEY_NAME, name);
			args.put(KEY_PASS, pass);
			return db.update(DBTABLE, args, KEY_ID + "=" + id, null) > 0;
		}

Thanks!

Its very simple,

if

db.update(DBTABLE, args, KEY_ID + "=" + id, null)

returns number greater than 0 (zero), method updateUser will return true.

if

db.update(DBTABLE, args, KEY_ID + "=" + id, null)

returns number lower or equal to 0 ( zero), method updateUser will return false.

		}

If the row affected return statement will return 1 or return 0
