SQL 查询如果两个日期在组中相同，则按天获取最新项目

Question

I'm working on a reporting system where there should only be the newest entry of each day over multiple days returned by my SQL query so that there's no dupes in the report. MY current query works fine in that if there are more than one entry on any given day it will get the newest entry for that day in my INNER JOIN , the problem that I'm facing though is if two created values for a report are exactly the same it returns both entries, I only need one.

Here's my query:

SELECT
    *
FROM
    tlp_consolidated_reports AS ConsolidatedReport
INNER JOIN
(
    SELECT
        DATE(created) AS created_at,
        MAX(created) AS max_created_at
    FROM
        tlp_consolidated_reports
    WHERE
        type = 'commissions'
        AND
        user_id = '33'
        AND
        report_from >= '2022-08-01 00:00:00'
        AND
        report_to <= '2022-08-31 23:59:59'
    GROUP BY DATE(created)
) AS joinedReport
  ON joinedReport.created_at = DATE(ConsolidatedReport.created)
  AND
  joinedReport.max_created_at = ConsolidatedReport.created
WHERE
    ConsolidatedReport.type = 'commissions'
    AND
    ConsolidatedReport.user_id = '33'
    AND
    ConsolidatedReport.report_from >= '2022-08-01 00:00:00'
    AND
    ConsolidatedReport.report_to <= '2022-08-31 23:59:59'
ORDER BY
    ConsolidatedReport.created DESC

I tried added a LIMIT 1 into my INNER JOIN just after the GROUP BY but then this only ever returns one entry over the whole period which isn't right.

Example:

Reports:

2022-08-09 21:00:00
2022-08-08 15:00:00
2022-08-07 14:00:00
2022-08-07 14:00:00
2022-08-07 13:00:00

Currently returns

2022-08-09 21:00:00
2022-08-07 14:00:00
2022-08-07 14:00:00

So the 7th is returning the newest, but because the created is the same, it returns both, how can I limit it to one if this scenario is encountered?

Answer 1

If the creation date is the same, then return any of them?

WITH data AS (
SELECT *, ROW_NUMBER() OVER(ORDER BY created) AS numb
FROM tlp_consolidated_reports
WHERE
        type = 'commissions'
        AND
        user_id = '33'
        AND
        report_from >= '2022-08-01 00:00:00'
        AND
        report_to <= '2022-08-31 23:59:59'
)
SELECT data.*
FROM data 
JOIN (
    SELECT max(numb) AS numb
    FROM data
    GROUP BY DATE(created)
) AS grData ON data.numb = grData.numb
ORDER BY data.created DESC
