如何在 Oracle 9i 中的 where
条件中使用计算列?
我想使用类似的东西
select decode (:pValue,1,
select sysdate from dual,
select activation_date from account where AcNo = 1234) as calDate
where caldate between startDate and endDate;
最佳答案
您可以使用内嵌 View :
select calcdate from
(
select startDate, endDate,
decode (:pValue,1,
select sysdate from dual,
select activation_date from account where AcNo = 1234) as calcdate
)
where calcdate between startDate and endDate;
