Dongsheng He updated CALCITE-6604:
----------------------------------
Description:
Converting the `RelNode` with `SqlWindowTableFunction` will fail with exception:
For example
{code:java}
SELECT * FROM TABLE(TUMBLE(TABLE employee, DESCRIPTOR(hire_date), INTERVAL '1'
MINUTE)){code}
RelNode like this:
{color:#ce9178}LogicalProject{color}
{color:#cccccc}
{color}{color:#c586c0}|{color}{color:#569cd6}-{color}{color:#f44747} {color}
{color:#ce9178} | -- inputs: <-----------{color}
{color:#ce9178} | |--- LogicalTableScan |{color}
{color:#ce9178} | |{color}
{color:#ce9178} -- RexCall: |{color}
{color:#ce9178} | op: SqlWindowFunction |{color}
{color:#ce9178} | operands: [DESCRIPTOR(INPUT_REF(3)), INTERVAL]{color}
{code:java}
{code}
The cause of this issue is:
{code:java}
visit(TableFunctionScan e) {
...
final Context context = tableFunctionScanContext(inputSqlNodes);
...
}{code}
`tableFunctionScanContext` only refer `inputSqlNodes` to fields, when handle
`DESCRIPTOR(hire_date)`, the `hire_date` is a `RexInputRef` with index 3, but
there is only one field (`inputSqlNodes`) , it cause a
IndexOutOfBoundsException.
