Subject: Re: Null literals in AggregateReduceFunctionsRule
Adding a cast around the null literal makes sense. I would use
“rexBuilder.makeCast(type, constantNull())” rather than

Adding a cast around the null literal makes sense. I would use
“rexBuilder.makeCast(type, constantNull())” rather than
“rexBuilder.makeNullLiteral(type.getSqlTypeName())” because there’s a chance
that the type needs precision & scale.
Can you please create a Calcite jira case and submit a pull
Hello community,
I have worked for support standard deviation/variance functions in Flink SQL
[1] and I got exception " Type NULL is not supported. Null values must have a
supported type.".
I started search root cause and found what problem come up from
AggregateReduceFunctionsRule[2].
