替换SQL Pivot中的空值 [英] replace null values in sql pivot

问题描述

我有以下查询:

SELECT *
FROM Table1
PIVOT
(
  SUM(Value)
  FOR [Period] IN ([06/1/2007],[07/1/2007])
)
AS p

返回的某些行为null，但我想将其替换为0.

Some of the rows returned are null but i want to replace them with 0.

我已经尝试过SUM(ISNULL(Value,0)) as Val，但是它不起作用. (这是不正确的语法)

I've tried SUM(ISNULL(Value,0)) as Val but it's not working. ( it's saying incorrect syntax)

推荐答案

哦，我在错误的地方使用了ISNULL.

Ohh, I was using ISNULL in the wrong place.

查询应如下所示:

SELECT ID,ISNULL([06/1/2007],0), ISNULL([07/1/2007],0)
FROM Table1
PIVOT
(
  SUM(Value)
  FOR [Period] IN ([06/1/2007],[07/1/2007])
)
AS p
