## Jira Link [CALCITE-7480](https://issues.apache.org/jira/browse/CALCITE-7480) ## Changes Proposed The problem the PR is going to fix is invalid output SQL after unparsing of `MATCH_RECOGNIZE` with `ORDER BY` or `PARTITION BY` example ```sql SELECT * FROM (SELECT empno, deptno from sales.emp) MATCH_RECOGNIZE ( PARTITION BY empno ORDER BY deptno MEASURES FINAL COUNT(A.deptno) AS deptno PATTERN (A B) DEFINE A AS A.empno = 123 ) ``` is being unparsed as ```sql SELECT `T`.`EMPNO`, `T`.`DEPTNO` FROM `CATALOG`.`SALES`.`EMP` AS `EMP_ALIAS` MATCH_RECOGNIZE( PARTITION BY `*`.`EMPNO` ORDER BY `*`.`DEPTNO` MEASURES FINAL COUNT(`A`.`DEPTNO`) AS `DEPTNO` PATTERN (`A` `B`) DEFINE `A` AS PREV(`A`.`EMPNO`, 0) = 123) AS `T` ``` where ```sql PARTITION BY `*`.`EMPNO` ORDER BY `*`.`DEPTNO` ``` is not parsable anymore -- This is an automated message from the Apache Git Service.
