Oracle SQL 多列 <> 空值 Select

Question

SELECT * 
FROM GNGRB.LOAN 
WHERE LOAN, INTRST, RATE IS NOT NULL 
ORDER BY LOAN DESC;

请指出此查询中的错误。

Answer 1

SELECT * 
FROM GNGRB.LOAN 
WHERE LOAN IS NOT NULL
  AND INTRST IS NOT NULL
  AND RATE IS NOT NULL 
ORDER BY LOAN DESC;

Answer 2

可以看到loan、interest和rate都是number数据类型值，可以用+如下：

Select * from your_table t
 Where loan + interest + rate is not null

Oracle SQL Multi Column <> Null Select
