Could you please help me on this? which one is causing the issue.
Thanks in advanced.

You're doing a large amount of work filtering data from GL_DAILY_RATES presumably largely because you're applying a function to the date column.
The name of the column suggests it's already a date.
TO_DATE usage on a DATE would be wrong.
TO_DATE usage without a format mask would also be wrong.
AND to_date(gdr.conversion_date) = to_date(rctd.gl_date)
| 41 | TABLE ACCESS BY INDEX ROWID BATCHED | GL_DAILY_RATES | 33459 | 1 | 21808 |00:12:44.59 | 1838K| |* 42 | INDEX RANGE SCAN | GL_DAILY_RATES_U1 | 33459 | 1 | 21808 |00:13:08.16 | 1837K|
42 - access("GDR"."FROM_CURRENCY"="RCT"."INVOICE_CURRENCY_CODE" AND "GDR"."TO_CURRENCY"="GLL"."CURRENCY_CODE" AND "GDR"."CONVERSION_TYPE"='Corporate') filter(("GDR"."CONVERSION_TYPE"='Corporate' AND TO_DATE(INTERNAL_FUNCTION("GDR"."CONVERSION_DATE"))=TO_DATE(INTERNAL_FUNCTION("RCTD"." GL_DATE"))))So, you use access predicates on the index to get all these dates matching from_currency, to_currency and conversion_type - I imagine that could be a lot - and then you have to throw away all those dates you're not interested in AFTER you've applied a function to the date.
I presume the index is on the unadulterated CONVERSION_DATE field therefore you have to modify your SQL logic to make the most of that and question why that TO_DATE function is erroneously being applied there.
Assuming that both these columns are both dates then do either of them have a non-"zero" time portion.
If not then you don't need any function.
AND gdr.conversion_date = rctd.gl_date
If they do have times then you're probably after either BETWEEN or >= and <
AND gdr.conversion_date >= trunc(rctd.gl_date) AND gdr.conversion_date < trunc(rctd.gl_date)+1
-
Thank you, let me try without using to_date and let you know.
-
Rajesh123, I see another potential logic problem in the SQL. If the author is trying to compare against all days in January then I think the BETWEEN is written wrong:
- -
" rctd.gl_date BETWEEN To_date ('01-JAN-2018', 'DD-MON-YYYY') AND To_date ('31-JAN-2018', 'DD-MON-YYYY') "
- -
The end date would default to midnight on the 31 and what is really desired is < 1-Feb-2018. Either the time 23:59:59 needs to be provided as part of the end date test or as is my preference the code should be rewritten as
rctd.gl_date >= To_date ('01-JAN-2018', 'DD-MON-YYYY') and rctd.gl_date < to_date(01-FEB-2018','DD-MON-YYYY')

You are projecting six (six!) scalar subqueries. You could rewrite them to a join to just one subquery. Something like
select
sum(case line_type='LINE' then extended_amount else 0 end) inv_net_amount,
sum(case line_type='TAX' then extended_amount else 0 end) inv_tax_amount,
and so on.

You missed the union all, there's 12!
But we can see from the row source execution statistics that Oracle spent a grand total of 4 seconds doing this. Also, since 12c Oracle has been able to unnest scalar subqueries itself, it has in this circumstance (which is why we see the VW_SSQ_ "views" in the plan) but this is quite limited and obviously didn't manage to see that they all share similar filters with slight modifications.
I think Dom is pointing in the right direction.
-
I agree;
And while we can't always trust the timing information on rowsource execution stats when the number of times a line runs is high and it's workload is small, there is some confirmation in line 42 itself that the work done is high: 33,000 starts to do a range scan leading to 1.8M buffer gets means the average range scan is about 60 blocks - which could be a very large number of index entries examined (with an expensive double-conversion of a data column) to find an average of less than one row.

Rajesh,
Your code and plan were long enough to offer a few interesting points, but short enough to make it possible to say something fairly constructive in a blog note - so I've written about it on my blog: https://jonathanlewis.wordpress.com/2018/09/30/case-study-2/
You might be particularly interested in the closing warning - the result you get from your query may depend on the nls_date_format set by the user.

Thank you Andrew,
I removed to_date from date columns still same plan it is showing.

Thanks a lot excellent explanation.
