-------------------------------------
Summary: Support ANY type with binary compare / arithmetic
operators
Key: CALCITE-1453
URL: https://issues.apache.org/jira/browse/CALCITE-1453
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Jungtaek Lim
Assignee: Jungtaek Lim
Currently Calcite doesn't support applying binary compare / arithmetic
operators with ANY type. One of example is
CollectionTypeTest.testAccessNestedMapWithAnyTypeWithoutCast(). Without
explicit casting, it can't find the matching backup method, and complaining
there's no SqlFunctions.eq(Object, int).
There seems to several ways to resolve this, but at least we don't want to make
operator backup method for every combination of types. Needs to avoid this
approach.
When we're addressing this by having backup method, since we don't know the
runtime type for ANY type, even if we succeed to call backup method with
(Object, Object) parameters, two types can be different. This is OK for other
types, but not Number types. This should be well cared, too.
