Test cases:
{code}
select sum(a2) over(partition by a2 order by a2), count(*) over(partition by
a2,b2,c2) from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over() from t2
order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over(order by a2)
from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over(partition by a2
order by b2) from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), count(*) over(partition by b2
order by b2) from t2 order by 1,2;
select sum(a2) over(partition by a2 order by a2), sum(*) over(partition by b2
order by b2) from t2 order by 1,2;
-- mix window clause with over clause (different)
select
avg(a1) over w1,
sum(a1) over w1,
row_number() over (order by b1)
from t1
window w1 as (partition by c1);
-- Should not be disabled
select
avg(a1) over w1,
sum(a1) over w1,
sum(a1) over (partition by b1)
from t1
window w1 as (partition by b1);
{code}
> Disable multiple partition by clauses in the same sql query
