Question

我遇到了一个奇怪的语法错误，请帮助我解决它。

WITH A as (
SELECT ambtemp,
       date_trunc('hour', dt)+
       CASE WHEN date_part('minute', dt) >= 30
            THEN interval '30 minutes'
            ELSE interval '0 minutes'
       END as t
FROM temm),

B as(
SELECT ambtemp,t,

       max(ambtemp::float(23)) OVER (PARTITION BY t) as max_temp,
       min(ambtemp::float(23)) OVER (PARTITION BY t) as min_temp
FROM A),


 H AS (
SELECT *      
FROM B
WHERE (max_temp - min_temp) <= 0.2 )

UPDATE temm
SET ambtemp = (NULL)
WHERE dt IN H

正如您在代码中看到的那样，除了“WHERE dt IN H”以及我何时，所有代码都正常运行忽略这部分代码运行但在我遇到的代码存在以下错误：

ERROR:  syntax error at or near "H"
LINE 25: WHERE dt IN H
                     ^

Answer 1

试试这个：

UPDATE temm
SET ambtemp = (NULL)
WHERE dt IN ( SELECT ambtemp FROM H )

SQL代码中的语法错误
