QUESTION
When I try to run the below SQL:
...ANSWER
Answered 2018-May-31 at 06:22"it's a parameter."
Your posted SQL is mangled so this is not a working example (for instance you have a cross join with no join conditions so it will return a Cartesian product). Anyway it shows you the sort of thing you need to do:
QUESTION
I'm facing issues while writing the below code in SQL developer:
...ANSWER
Answered 2018-May-30 at 17:34You can't put other conditions inside the case expression clauses.
You could either switch to simpler Boolean logic:
QUESTION
Select pinv.pipeline_ref_id Invoice_No,
pinv.orig_company_id Company,
pinv.orig_terminal_id Terminal,
phwb.pipeline_ref_id HWB_No,

(pinv.pipeline_tx_status_date - ms.accounting_date) BL_Days, ih.billto_name BillTo_Name, ppi.partner_id BillTo_ID,
pinv.last_modified_by Executed_By, ih.oc_invoice_amt Invoice_Amount
From pipeline pinv
JOIN invoice_header ih ON pinv.pipeline_tx_id = ih.pipeline_tx_id
JOIN pipeline_relations prin ON pinv.pipeline_tx_id = prin.pipeline_tx_id

JOIN multisegment_status ms ON phwb.pipeline_tx_id = ms.pipeline_tx_id
JOIN pipeline_parties ppi ON ppi.partner_role = 'BT'
Where
(TRUNC(sf_get_local(pinv.pipeline_tx_status_date,pinv.status_date_tz_code)) between to_date('&1','DD-MON-YYYY:HH24:MI:SS') AND to_date('&2','DD-MON-YYYY:HH24:MI:SS'))
...ANSWER

sf_get_local()
is a function in your application, not an Oracle built-in, so you can look at its source to figure out what it does and we can't. However, I would guess it's converting a timestamp in UTC into a local timezone. The trunc()
removes the time element, so 2018-05-08 15:20:01.542
would become just 2018-05-08
, which seems a bit odd given the operands are expressed in date time formats to the second.
As for why "SQL is taking hours" it's hard for us to tell. Performance diagnosis requires a lot more detail. An explain plan would help. Find out more.
Obvious things to look at:
The WHERE
clause probably doesn't use an index (unless you have a function-based index on pipeline(trunc(sf_get_local(pipeline_tx_status_date,status_date_tz_code))
. The problem is you're filtering on a date range so it's hard for the optimizer to tell when using an index is a good thing. If the range is an hour and you are scanning five years' worth of data then an index is helpful. But not if the range spans a year and you have five years worth of data.
You're looking at an hour of data so maybe you'll get some benefit from building that function based index. Find out more.
This join is actually a CROSS JOIN:
