Description:
If we run the following queries with UNNEST operator, we get the expected
results:
{code:sql}
select * from UNNEST(array[3, 4]) as T2(y);
-- y=3
-- y=4
select * from UNNEST(array[array[3], array[4]]) as T2(y)
-- y=[3]
-- y=[4]
select * from UNNEST(array[ROW(3), ROW(4)]) as T2(y)
-- y=[3]
-- y=[4]
-- Is this result ok? (see first comment of the current ticket)
{code}
However, if we try to combine them with a correlation with some other values,
as we could do in more realistic examples:
{{select * from dept_nested as d, UNNEST(d.employees) e2}}
The first two return the expected results, but the last one throws an exception:
{code:sql}
select * from (values (1), (2)) T1(x), UNNEST(array[3, 4]) as T2(y);
-- x=1; y=3
-- x=1; y=4
-- x=2; y=3
-- x=2; y=4
select * from (values (1), (2)) T1(x), UNNEST(array[array[3], array[4]]) as
T2(y);
-- x=1; y=[3]
-- x=1; y=[4]
-- x=2; y=[3]
-- x=2; y=[4]
select * from (values (1), (2)) T1(x), UNNEST(array[ROW(3), ROW(4)]) as T2(y);
-- ERROR!!!
