Sergey Nuyanzin created CALCITE-7575:
----------------------------------------
Summary: Parser can not parse unparsed polymorphic table functions
with several table args
Key: CALCITE-7575
URL: https://issues.apache.org/jira/browse/CALCITE-7575
Project: Calcite
Issue Type: Sub-task
Components: core
Reporter: Sergey Nuyanzin
Assignee: Sergey Nuyanzin
probably the reason is that in parser there is a separate Arg0 and other args
example of query
{code:sql}
SELECT * FROM TABLE(SIMILARLITY(
TABLE emp PARTITION BY deptno,
TABLE emp PARTITION BY deptno))
{code}
is rewritten to
{code:sql}
SELECT * FROM TABLE(SIMILARLITY(
(SELECT `EMP`.`EMPNO`, `EMP`.`ENAME`, `EMP`.`JOB`, `EMP`.`MGR`,
`EMP`.`HIREDATE`, `EMP`.`SAL`, `EMP`.`COMM`, `EMP`.`DEPTNO`, `EMP`.`SLACKER`
FROM `CATALOG`.`SALES`.`EMP` AS `EMP`) PARTITION BY `DEPTNO`,
(SELECT `EMP`.`EMPNO`, `EMP`.`ENAME`, `EMP`.`JOB`, `EMP`.`MGR`,
`EMP`.`HIREDATE`, `EMP`.`SAL`, `EMP`.`COMM`, `EMP`.`DEPTNO`, `EMP`.`SLACKER`
FROM `CATALOG`.`SALES`.`EMP` AS `EMP`) PARTITION BY `DEPTNO`))
{code}
and parser fails to parse it
