> 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
> There is no such issue with PTF with only one {{TABLE}} arg
