> Key: CALCITE-3340
> URL: https://issues.apache.org/jira/browse/CALCITE-3340
> Project: Calcite
> Issue Type: Sub-task
> Reporter: Rui Wang

> Labels: pull-request-available
> Fix For: 1.22.0

> Time Spent: 2.5h

> The goal of this JIRA is to generate a logical plan for the following query:
> {code:java}
> SELECT *
> FROM TABLE(TUMBLE(
> TABLE ORDERS,
> INTERVAL '10' MINUTE))
> {code}
> This SQL query does not have DESCRIPTOR included, which is being tracked and discussed by CALCITE-3339.
> I expect we should generate a logical plan from this query that is similar to the following:
> {code:java}
> LogicalProject(ROWTIME=[$0], ID=[$1], PRODUCT=[$2], UNITS=[$3], wstart=[$4], wend=[$5])
> LogicalTableFunctionScan(invocation=[TUMBLE($3, 60000:INTERVAL MINUTE)], rowType=[RecordType(TIMESTAMP(0) ROWTIME, INTEGER ID, VARCHAR(10) PRODUCT, INTEGER UNITS, TIMESTAMP(0) wstart, TIMESTAMP(0) wend)])
> LogicalProject(ROWTIME=[$0], ID=[$1], PRODUCT=[$2], UNITS=[$3])
> LogicalTableScan(table=[[ORINOCO, ORDERS]])
> {code}
