Rui Wang updated CALCITE-3340: ------------------------------ Summary: Make TUMBLE be accepted as an operand for "FROM TABLE()" in validator (was: Make TUMBLE be accepted as an operand for COLLECTION_TABLE(TABLE syntax) in validator) > Make TUMBLE be accepted as an operand for "FROM TABLE()" in validator > --------------------------------------------------------------------- > > Key: CALCITE-3340 > URL: https://issues.apache.org/jira/browse/CALCITE-3340 > Project: Calcite > Issue Type: Sub-task > Reporter: Rui Wang > Assignee: Rui Wang > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > For query: > SELECT * > FROM TABLE(TUMBLE( > TABLE ORDERS, > DESCRIPTOR(ROWTIME), > INTERVAL '10' MINUTE)) > (note reuse TUMBLE operator than use a new unresolved one) > Calcite validator will does a step to do registration and > "TABLE(TUMBLE(...))" will hit [1], where "TUMBLE(...)" will be passed to [2] > again but there is no matching Sqlkind handling for "TUMBLE" (note that > TUMBLE's node kind is TUMBLE). > It seems we should support TUMBLE in [2]. The details of how to support it > needs a bit more discussion and prototyping. > [1]: > https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/sql/validate/SqlValidatorImpl.java#L2244 > [2]:https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/sql/validate/SqlValidatorImpl.java#L2031 -- This message was sent by Atlassian Jira (v8.3.2#803003)
