query parsing error not detected till the end about sqlwindowing

Yes, this is a limitation. Currently the groovy expressions are not validated.
But if all you are doing is referring a column then for e.g.
sum() will not catch the issue but
sum(col) will catch the issue.

does this make sense. Or send me your query, let me take a look.

the error was not in the "with" clause but rather the "select" that comes after the with. I was typing a wrong column name in there and it didn't detect the error till the final reduce.

Also, it doesn't catch division by zero and reports a ratio as Infinity in the final output; not sure if that's a problem or feature, but just wanted to mention.

[hbutani]

can you post your query.

[achaubal]

from <select acct_no,to_date(my_dt) my_date,
tot_bal,denom_bal
from mon_2011_08_all_attrib>
partition by acct_no
order by acct_no,my_date asc
with rank() as r,
avg (<tot_bal/denom_bal>) over rows between 3 preceding and current row as ma4_ratio,
last_value(<tot_bal/denom_bal>) over rows between 1 preceding and current row as prev_ratio,
ntile(5) as percentile_5
select acct_no,my_date,my_ratio,r,ma4_ratio,prev_ratio,percentile_5
into path='ma_6_2011_08';

my_ratio is the column that was not available in the query, I cause made the ratio up in the "with" clause

The error indication should happen w/o delay. This was related to issue 5.
But let me check about catching the incorrect column name in the select list
