Returns. If the value of the input expression is 0, this returns NULL. Otherwise, this returns the value of the input expression. The data type of the return value is NUMBER(p, s) (if the input is a fixed-point number) or DOUBLE (if the input is a floating point number ). For fixed-point numbers, the exact values of ‘p’ (precision) and ‘s ...Optionally specifies whether NULL values are returned before/after non-NULL values, based on the sort order (ASC or DESC).

The above df was created with column name “name” while the returned column name after collect() was called became “NAME”.
