--------------------------------------
Summary: Impossible condition in return type inference for
SqlIntervalOperator?
Key: CALCITE-5183
URL: https://issues.apache.org/jira/browse/CALCITE-5183
Project: Calcite
Issue Type: Bug
Reporter: Steven Talbot
I could be wrong here, but I don't see how to make this work, and I don't see
any tests for it being used on the relBuilder side of the fence (where the
"impossible" type inference is invoked for me).
[https://github.com/apache/calcite/commit/03c76a7d2b896042ab417ddc36f1849f874ad3dd#diff-f6836cabfabc14be277e9f7406ab38996aaa45bac86969cecd64189c2fd7c745R57]
requires the second argument to the Interval call to be a
SqlIntervalQualifier. In the context of RexCallBinding, I don't believe this is
possible, since the argument has to be a RexLiteral, and RexLiteral exposes no
way to directly wrap a value as a SqlIntervalQualifier like this. Again, this
is where my reading of the code gets uncertain, but neither signature of
RexBuilder.makeIntervalLiteral will give you what you want, and I don't see any
way this could be possible.
This issue means that there seems to be no way to use
`SqlStdOperatorTable.INTERVAL` with RelBuilder.call.
