    WITH CteName1 (Cte1Columns) AS (
  YourCte1
),
CteName2 (Cte2Columns) AS (
  YourCte2
),

SELECT ...
  • CTEs are placed at the start of the query. They are introduced with WITH.
  • You can skip column definitions if you provide aliases for columns containing aggregates and other function results.
  • CTEs are temporary sets of rows similar to subqueries. Thanks to them, your query becomes better organized and easier to read.
