David Savage commented on CALCITE-277:
--------------------------------------
Just wondering, did this problem ever get fixed or was a work around found?
I'm experiencing a similar error when trying to use UNNEST on a java array:
org.apache.calcite.runtime.CalciteContextException: From line 3, column 12 to
line 3, column 32: Cannot apply 'UNNEST' to arguments of type
'UNNEST(<JAVATYPE(CLASS [LJAVA.LANG.OBJECT;)>)'. Supported form(s):
'UNNEST(<MULTISET>)'
'UNNEST(<ARRAY>)'
'UNNEST(<MAP>)'
UNNEST(<MULTISET>)

For background, I'm using Calcite via NiFi and have the following trivial
example:
FLOWFILE record:
[
{
"id": "1",
"tags": ["a", "b", "c"]
},
{
"id": "2",
"tags": ["a", "b"]
},
{
"id": "3",
"tags": ["d", "e", "f"]
}
]
Query:
SELECT id, flattened_tags
FROM FLOWFILE
CROSS JOIN UNNEST(FLOWFILE.tags) AS flattened_tags
