Steven Talbot created CALCITE-5183: -------------------------------------- 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. -- This message was sent by Atlassian Jira (v8.20.7#820007)
