I have a String s="apple"
What is the difference between s.equals("apple") and "apple".equals(s)? and which is better? Please post the correct answer

That depends which language you are using. Both are valid syntax in Java, but they mean different things. I think only the one with = is valid SQL syntax, but you should check whether you want "apple" or 'apple' in SQL.
If you try passing s in Java and s is null, then s.equals... will throw a NullPointerException and "apple".equals(s) will evaluate to the value false.
