Nic Townsend commented on FLINK-31778:
--------------------------------------
Hi, I have encountered this in an additional scenario:
{code:java}
select commissions from (select ROW(ARRAY[ROW(123), ROW(234)]) commissions);
{code}
+----+--------------------------------+
| op | commissions |
+----+--------------------------------+
| +I | ([(123.0), (234.0)]) |
+----+--------------------------------+
{code:java}
create temporary view test as select commissions from (select
ROW(ARRAY[ROW(123), ROW(234)]) commissions);
select commissions from test; {code}
+----+--------------------------------+
| op | commissions |
+----+--------------------------------+
| +I | ([(234.0), (234.0)]) |
+----+--------------------------------+
Is this the same problem with the `BinaryRowWriter` or should I raise a new
issue? Many thanks!
