Spotfire-什么是Oracle Decode？

Question

我正在嘗試復制以下內容：

select name, salary, decode(salary > 100, "Nice Job", job) as job
from blah...


blah table being:
name
salary
job

是否有等效的解碼或if或switch之類的東西？

Answer 1

嘗試：

select name, salary, case when salary > 100 then "Nice Job" else job end as job
from blah...

Answer 2

如果job是一個整數，則需要將其轉換為字符串：

select (case when salary > 100 then "Nice Job" else cast(job as varchar(255))
        end) as job
