    Hi Ganesh and welcome to Community!

    First, let's try using "WITH RECURSIVE" instead of just "WITH". Presto does not support "WITH" directly.

    Please let me know if you are still experiencing trouble!

    Hi Regan,

    I tried with recursive but it displays an error than with recursive is not supported. 

    simple cte:

    WITH recursive "Numbers" AS
    (
    SELECT 1 AS "n"
    UNION ALL
    SELECT "n" + 1
    FROM "Numbers"
    WHERE "n"+1 <= 10
    )
    SELECT *
    FROM
    "Numbers"

    I am getting the following error.

    [Query failed (#20210602_225140_03779_m6jsc): line 1:1: Recursive WITH queries are not supported]

     

    Thanks,

    Ganesh
