display data from previous rows
i have a result set from an existing Oracle View attached with the question. i need to add 2 more columns to this view.
here is the brief business logic for those 2 dates
Service date: this is typically the hire_date, if a person is terminated and rehired within 12 months then its Service date is retained but if a person is rehired after 12 months of termination then its rehire_date is the Service_date
term service date: if a person is rehired after 12 months of termination then its previous hire date is the term service date
i am trying to write a logic something like
case when prev_endofday_status = 'TF' and hire_flag = 1 and hire_code = 'REHIRE' and add_months(term_date, 12) < hire_date then....??

odd data, that employee got hired multiple times on the same date
that's probably why you can't get it to work

Attached is the spreadsheet with the 2 new columns.
And I should take back the logic i wrote for the new date columns,
Service date: this is the hire_date!
term service date: if a person is rehired after 12 months of termination then its previous hire date is the term service date

your data doesn't make sense !
column B and M both have the title hire_date
and you indicate service date is the hire date
leave out all the columns which are not used for this problem
it just confuses

To recap what you have I listed some assumptions
Service date:
this is typically the hire_date, if a person is terminated
and rehired within 12 months then its Service date is retained
but if a person is rehired after 12 months of termination then its rehire_date is the Service_date
service_date1 = hire_date
service_date2 = hire_date when rehired within 12 months
service_date3 = hire_date2 (re_hire_date) when rehired after 12 months
term service date:
if a person is rehired after 12 months of termination
then its previous hire date is the term service date
term_date1 = term_date
term_date2 = hire_date when rehired after 12 months (the hire date would of been the previous hire date)
you can then write sql like, the test1 table is just a table i created to test the results, but you would want to replace that with the actual table. If the sql looks good, then I would suggest you create this as a view
select a.*
, case hire_code
when 'REHIRE' then
case when (add_months(a.term_date, 12) < a.hire_date2)
then hire_date -- this is the original hire_date
else hire_date2 -- this is the re-hire_date
end
else
hire_date -- this is the original hire_date
end SERVICE_DATE
, case hire_code
when 'REHIRE' then
case when (add_months(a.term_date, 12) < a.hire_date2)
then cast(NULL as date)
else hire_date -- this is the previous hire_date
end
else
term_date -- this is the original term_date
end term_date2
