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

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.

Ken
