'Translate LEFT JOIN UNNEST in Presto/Trino to Hive [duplicate]
Was wondering what the equivalent of the below in Presto/Trino is
LEFT JOIN UNNEST(colname) as t(renamedcol) on true
On Hive
I know CROSS JOIN UNNEST translates to LATERAL VIEW EXPLODE but I can't figure out the syntax for LEFT JOIN UNNEST for whatever reason
Solution 1:[1]
For those wondering, this is equivalent to
LATERAL VIEW OUTER explode()
