aws athena 查询以获取大于特定数字的计数

Question

如何使用 AWS Athena 查询获得大于特定数字的

count

？

SELECT
    concat(cast(date as varchar),' ',substr(time,1,5)) as datetime,
    requestip,
    count(*) as count 
FROM "tk_logs"."btb-cf-aug-2023" 
WHERE
        uri like '/topics/%'
    and cast(concat(cast(date as varchar),' ',substr(time,1,5)) as varchar) >= '2023-08-07 00:59' 
    and count >=100
GROUP BY 1,2
ORDER BY 1 asc

我尝试了上述查询，但出现错误

 Column 'count' cannot be resolved or requester is not authorized to access requested resources

Answer 1

该错误可能是由

count >=100

引起的，因为它是完全聚合的。尝试将其移动到像这样的

HAVING

：

SELECT
    concat(cast(date as varchar),' ',substr(time,1,5)) as datetime,
    requestip,
    count(*) as count 
FROM "tk_logs"."btb-cf-aug-2023" 
WHERE
        uri like '/topics/%'
    and cast(concat(cast(date as varchar),' ',substr(time,1,5)) as varchar) >= '2023-08-07 00:59' 
GROUP BY 1,2
HAVING count(*) >= 100
ORDER BY 1 asc
