In phpmyadmin in a mariadb install, I have a SQL statement
SELECT `datepaid`, SUM(`total`) FROM `tblinvoices` WHERE `status` = "paid" AND `total` > 0 GROUP BY YEAR(datepaid)*100 + MONTH(datepaid) ORDER BY `datepaid` ASC
The output is as expected, I get a list of totals grouped by month, ordered by month. The last 5 rows look like this:
2020-06-09 13:01:31 4485.56
2020-07-07 12:36:25 4519.69
2020-08-03 13:02:29 3685.26
2020-09-26 05:49:25 4371.98
2020-10-10 16:47:32 5135.75
At the bottom of the list of all rows, I check all, then click export (under the results, not in the top menu).
In the resulting CSV the last 5 rows are
"2020-06-09 13:01:31","29.00"
"2020-07-07 12:36:25","130.50"
"2020-08-03 13:02:29","99.00"
"2020-09-26 05:49:25","385.00"
"2020-10-10 16:47:32","46.20"
It looks like the output has included one of the rows in the group, rather than the group total.
Am I doing something wrong (most likely) or is this some sort of bug?
[UPDATE]
Based on the info from @nbk I found a solution and learned something, the INTO command
`INSERT INTO `another_table` SELECT `datepaid`, SUM(`total`) FROM `tblinvoices` WHERE `status` = "paid" AND `total` > 0 GROUP BY YEAR(datepaid)*100 + MONTH(datepaid) ORDER BY `datepaid` ASC
