Common Table Expressions: no nesting, but consecutively usage – via Stack Overflow
Posted by jpluimers on 2016/09/28
Common table expressions are awesome. They work in at least Oracle and SQL Server.
You cannot nest them, but you can use them consecutively. Thanks spender for explaining that:
WITH
x AS
(
SELECT * FROM MyTable
),
y AS
(
SELECT * FROM x
)
SELECT * FROM y
