## Jira Link [CALCITE-7471](https://issues.apache.org/jira/browse/CALCITE-7471) in case of toggled `identifierExpansion` and missed alias for table there should be generated one. However in case of `MATCH_RECOGNIZE` it is missed (the PR is going to fix it) example of query ```sql SELECT * FROM emp MATCH_RECOGNIZE ( MEASURES FINAL COUNT(A.deptno) AS deptno PATTERN (A B) DEFINE A AS A.empno = 123 ) ``` unparsed query (there is `EXPR$0` in `SELECT` however it is not defined anywhere) ```sql SELECT `EXPR$0`.`DEPTNO` FROM `CATALOG`.`SALES`.`EMP` AS `EMP` MATCH_RECOGNIZE( MEASURES FINAL COUNT(`A`.`DEPTNO`) AS `DEPTNO` PATTERN (`A` `B`) DEFINE `A` AS PREV(`A`.`EMPNO`, 0) = 123) ``` -- This is an automated message from the Apache Git Service.
