-It is not allowed to mix `UNION DISTINCT` and `UNION ALL` in the same chain of clauses.
-This can be solved by enclosing one or more `UNION` of the same type in curly braces
-allowing the enclosed query to be used as an argument to the outer `UNION`.
+To combine `UNION` (or `UNION DISTINCT`) and `UNION ALL` in the same query, enclose one or more `UNION` operations of the same type in curly braces.
+This allows the enclosed query to act as an argument that can be combined with an outer `UNION` operation of any type.
