What is the most feasible way to emulate the below MySQL function into
postgreSQL. Since the isnull() function is no longer supported in 9.6
version. I have tried every trick in the hat to get the desired results.
Still 'RPG INV' doesn't show only the other two then options show up.
(case
when
((`s`.`Funding_Date` = '')
and (isnull(`s`.`Actual_Close_Date`)
or (`s`.`Actual_Close_Date` = '')))
then
'RPG_INV'
when
((isnull(`s`.`Funding_Date`)
or (`s`.`Funding_Date` <> ''))
and ((`s`.`Actual_Close_Date` = '')
or isnull(`s`.`Actual_Close_Date`)))
then
'Builder_Inventory'
else 'Owner_Inventory'
end) AS `Lot_Status`
Hi. Over the years I have gotten a lot of patient assistance from this mailing list, for which I am abundantly grateful. In light of that, I offer the following "translations," which are specifically in response to your question about emulating the SQL above:
and (isnull(`s`.`Actual_Close_Date`)
--> and (`s`.`Actual_Close_Date` IS NULL)
((isnull(`s`.`Funding_Date`)
--> (`s`.`Funding_Date` IS NULL)
or isnull(`s`.`Actual_Close_Date`)))
-->or (`s`.`Actual_Close_Date` IS NULL)))
HTH, and Cheers.
