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`,
aklaver@test=> select 1 is null;
?column?
----------
f
(1 row)
aklaver@test=> select null is null;
?column?
----------
t
or
^
aklaver@test=> select 1 isnull;
?column?
----------
f
(1 row)
aklaver@test=> select null isnull;
?column?
----------
t
(1 row)
