What problem does this PR solve?
Issue Number: close #52755
Problem Summary:
What changed and how does it work?
Use
max
function instead offirst_row
function.if the query is
t.id = all (select s.id from s)
, it will be rewrote tot.id = (select s.id from s having count(distinct s.id) <= 1 and [all checker])
.If there is NULL in the
s.id
column, s.id should be the value that isn't null in condition t.id == s.id. So use function max to filter NULL.Check List
