Subject: [GENERAL] isnull() function in pgAdmin3

Hi,

I am trying to emulate the isnull() function used in MySQL into postreSQL. I have tried different ways such is null but it's not producing the results desired. I am doing a data migration from MySQL into postgreSQL and need help with the isnull() in pgAdmin3.

Any assistance provided would be greatly appreciated.

Thanks,

In MySQL:

(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`,

__________________________________________________________________________________________________________

isnull(`s`.`Actual_Close_Date`) in MySQL is equivalent to:

s.actual_close_date IS NULL in Postgres.

What exactly didn't work for you?
