Ran Tao updated CALCITE-6040:
-----------------------------
Description:
we have a simple test case:
{code:java}
f.checkScalar("map[1, null]", "{1=null}",
"(INTEGER NOT NULL, NULL) MAP NOT NULL"); {code}
The result is:
{noformat}
java.lang.AssertionError: Query: values (map[1, null])
Expected: is "(INTEGER NOT NULL, NULL) MAP NOT NULL"
but: was "(INTEGER NOT NULL, INTEGER) MAP NOT NULL"
{noformat}
however, the asserted actual result "(INTEGER NOT NULL, INTEGER) MAP NOT NULL"
for this case is wrong. If we switch to this asserted actual result it throws
another exception:
{noformat}
java.lang.AssertionError: Query: select map[p0, null] from (values (1)) as t(p0)
Expected: is "(INTEGER NOT NULL, INTEGER) MAP NOT NULL"
but: was "(INTEGER NOT NULL, NULL) MAP NOT NULL"
{noformat}
No matter how you write this result type in test case, it is wrong.
by checking the plan, it seems the deduced value type of NULL has converted to
INTEGER.
