Rui Wang created CALCITE-3339: --------------------------------- Summary: DESCRIPTOR as a SQL operator in SqlStdOperatorTable Key: CALCITE-3339 URL: https://issues.apache.org/jira/browse/CALCITE-3339 Project: Calcite Issue Type: Sub-task Reporter: Rui Wang Assignee: Rui Wang
For query: SELECT * FROM TABLE(TUMBLE_TVF( TABLE ORDERS, // or could be TABLE(ORDERS) DESCRIPTOR(ROWTIME), INTERVAL '10' MINUTE)) TABLE ORDERS is converted to SqlPrefixOperator, but DESCRIPTOR(ROWTIME) has no mapping in SqlStdOperatorTable. There are two options: 1. There is a SqlColumnListConstructor which serves the same(similar) purpose to specific a list of column. 2. We create a new operator for DESCRIPTOR. Reuse existing code is always good so we can start from option one and see if it works. -- This message was sent by Atlassian Jira (v8.3.2#803003)
