SQL column list required error when creating a View

Make sure your column names are unique if not then rename them using the AS clause.
It could be possible that you renamed column names to the same name using the AS clause. Here is the explanation from IBM information center

SQL0153N -
A column list must be specified in a CREATE VIEW statement, a common table expression or in a CREATE TABLE statement containing an as-subquery-clause when:

• any element of the SELECT list in the fullselect is other than a column name and is not named using the AS clause.
• any two elements are the same column name that were not renamed using the AS clause.
