Github user tarekauel commented on the pull request: https://github.com/apache/spark/pull/6804#issuecomment-113029712 Yeah, that's a good comment. I checked the String expressions and it does already the null check, see https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/stringOperations.scala#L173-L182 So it won't be null and a valid result will be provided, if a value is null. I think the result is even better, because it returns null and not false which is way better.
