问题
I want to write a recursive query using CTE in Presto to find Employee Hierarchy. Do Presto support recursive query? When I write simple recursion as
with cte as(select 1 n
union all
select cte.n+1 from cte where n<50)
select * from cte
It gives error that
Error running query: line 3:32: Table cte does not exist回答1:
Presto grammar supports WITH RECURSIVE name AS ..., but recursive WITH queries are not implemented.
This is tracked as a feature request: https://github.com/prestosql/presto/issues/1122
