Sergey Nuyanzin updated CALCITE-7486:
-------------------------------------
Description:
Issue is same for {{LAST}}, {{FIRST}}, {{PREV}}, {{NEXT}}
example of query
{code:sql}
SELECT *
FROM emp
MATCH_RECOGNIZE (
MEASURES
FIRST(DOWN.empno + DOWN.deptno + 1) AS bottom_total
PATTERN (DOWN{2,})
DEFINE
DOWN AS EMP.EMPNO < 1
)
{code}
while unparsing it will be unparsed as
{code:sql}
SELECT `EXPR$0`.`BOTTOM_TOTAL`
FROM `CATALOG`.`SALES`.`EMP` AS `EMP` MATCH_RECOGNIZE(
MEASURES FINAL (FIRST(`DOWN`.`EMPNO` + `DOWN`.`DEPTNO`, 0) + FIRST(1, 0)) AS
`BOTTOM_TOTAL`
PATTERN (`DOWN` { 2, })
DEFINE `DOWN` AS `EMP`.`EMPNO` < 1) AS `EXPR$0
{code}
the problematic part is {{FIRST(1, 0)}}
