MAX returns NULL - ms-access

I'm a newbie to Access.
I have two tables (Tp and Temp). I want to update a field in the Temp table with the max of that field in the Tp table.
Max([TP]. [QCTNO]) this returns null in an update query, but if I use it in a select query, it returns a value.

Although saving calculated value is strongly discouraged (not recommended) but if you really interested to do it then use domain aggregate function DMAX() to update query. Try-
UPDATE TempTable SET [QCTNO]=DMAX("[QCTNO]","[TP]");

MYSQL with SUM results and GROUP BY and SUM Again

I have a query that I need to SUM the trid column after summing the raised amount
SELECT
`ppm_campaign_id`.`meta_value` AS `campaign_id`,
`trasnlations`.`trid` AS `trid`,
`ppm_campaign_value`.`meta_value` AS `raised`
FROM (((`thf_posts` `posts`
LEFT JOIN `thf_postmeta` `ppm_campaign_id`
ON (((`ppm_campaign_id`.`meta_key` = 'campaign_id')
AND (`ppm_campaign_id`.`post_id` = `posts`.`ID`))))
LEFT JOIN `thf_postmeta` `ppm_campaign_value`
ON (((`ppm_campaign_value`.`meta_key` = 'campaign_value')
AND (`ppm_campaign_value`.`post_id` = `posts`.`ID`))))
LEFT JOIN `thf_icl_translations` `trasnlations`
ON ((`trasnlations`.`element_id` = `ppm_campaign_id`.`meta_value`)))
WHERE ((`ppm_campaign_id`.`meta_value` IS NOT NULL)
AND (`trasnlations`.`trid` IS NOT NULL))
GROUP BY `ppm_campaign_id`.`meta_value`
Result
campaign_id trid raised
1022 564 4137.5
1031 564 3937.5
1698 653 3010
1700 655 10
1702 657 750
1712 653 3030
1713 655 20
1727 657 20
2163 682 0.9
2164 682 50
2166 683 200
2168 684 50
Now I want the sum of trid combined so summing trid = 682 the result of raised should be 50.9 in both campaign_id
Expected Result
campaign_id trid raised
1022 564 8075
1031 564 8075
1698 653 3010
1700 655 10
1702 657 750
1712 653 3030
1713 655 20
1727 657 20
2163 682 50.9
2164 682 50.9
2166 683 200
2168 684 50
Considering the output of your query is stored in temptable. Please try the below query. Hope it helps.
SELECT t1.campaign_id, t1.trid, t2.raised_sum
FROM temptable t1 JOIN (
SELECT trid, SUM(raised) as raised_sum
FROM temptable GROUP BY trid) t2
ON t1.trid=t2.trid
GROUP BY t1.campaign_id, t1.trid, t2.raised_sum;
If more details on the tables included in your query and sample data can be given, we can try to get the data directly from them.

Delete previous entry and update table with current entry - mySql

Say below is my table
entryID ID Number locationId timestamp
331 136 7 1 5/30/2018 9:23
332 136 7 1 5/30/2018 9:25
333 136 9 1 5/30/2018 9:25
334 136 11 1 5/30/2018 9:25
335 136 11 1 5/30/2018 9:25
336 136 9 1 5/30/2018 9:26
337 137 1 2 6/4/2018 8:45
338 137 2 2 6/4/2018 8:47
339 137 7 2 6/4/2018 8:47
340 137 7 2 6/4/2018 8:47
I would want to filter them by ID and locationId, delete the duplicate rows ("Number" is the column which carries duplicate values) and see the results as shown below after querying the table filtered by locationId = 1.
entryID ID Number locationId timestamp
332 136 7 1 5/30/2018 9:25
335 136 11 1 5/30/2018 9:25
336 136 9 1 5/30/2018 9:26
337 137 1 2 6/4/2018 8:45
338 137 2 2 6/4/2018 8:47
339 137 7 2 6/4/2018 8:47
340 137 7 2 6/4/2018 8:47
If locationId = 2, below is the result I would expect to see.
entryID ID Number locationId timestamp
331 136 7 1 5/30/2018 9:23
332 136 7 1 5/30/2018 9:25

334 136 11 1 5/30/2018 9:25
335 136 11 1 5/30/2018 9:25
336 136 9 1 5/30/2018 9:26
337 137 1 2 6/4/2018 8:45
338 137 2 2 6/4/2018 8:47
340 137 7 2 6/4/2018 8:47
The requirement is poorly explained. Nevertheless, assuming that timestamp really is a timestamp, then I suspect that you're after something like this...
(Remember to back up your data prior to deleting anything!!!)
DELETE x
FROM my_table x
LEFT
JOIN
( SELECT locationid
, number
, MAX(entryid) entryid
FROM my_table
GROUP
BY locationid
, number
) y
ON y.locationid = x.locationid
AND y.number = x.number
AND y.entryid = x.entryid
WHERE y.entryid IS NULL;

select query to get those result where for every unique value of column 3, column 2 has bothval1 and val2

I need to select those records from above table where for every unique value in column 'ID', column 'TYPE' have value 6 and 7 both.
Result of this select query would be as below:

MySql query - Grouping by date ranges?

I'm trying to write a query that will return data grouped by date ranges and am wondering if there's a way to do it in one query (including the calculation), or if I need to write three separate ones? The dates in my table are stored as unix timestamps.
For example, my records look like this:
id type timestamp
312 87 1299218991
313 87 1299299232
314 90 1299337639
315 87 1299344130
316 87 1299348977

501 343 1304281015
502 343 1304281200
503 343 1304281287
504 343 1304281447
505 343 1304281874
566 90 1305222137
567 343 1305250276

I'm trying to write a query that will find all records with a "created" date between:
2011-05-01 and 2011-06-01 (Month)
2011-03-01 and 2011-06-01 (Quarter)
2010-05-01 AND 2011-06-01 (Year)
I tried the following (in this case, I hardcoded the unix value for just the month to see if I could get it to work... ):
SELECT COUNT(id) AS idCount,
MIN(FROM_UNIXTIME(timestamp)) AS fromValue,
MAX(FROM_UNIXTIME(timestamp)) AS toValue
FROM uc_items
WHERE ADDDATE(FROM_UNIXTIME(timestamp), INTERVAL 1 MONTH)
>= FROM_UNIXTIME(1304233200)
But, it doesn't seem to work because the fromValue is: 2011-04-02 21:12:56 and the toValue is 2011-10-25 06:20:14, which, obviously, isn't a date between 5/1/2011 and 6/1/2011.
This aught to work:
SELECT COUNT(id) AS idCount,
FROM_UNIXTIME(MIN(timestamp)) AS fromValue,
FROM_UNIXTIME(MAX(timestamp)) AS toValue
FROM uc_items
WHERE timestamp BETWEEN UNIX_TIMESTAMP('2011-05-01') AND UNIX_TIMESTAMP('2011-06-01 23:59:59')
Also, as a performance tip - avoid applying functions to columns in your tables in a WHERE clause (e.g you have WHERE ADDDATE(FROM_UNIXTIME(timestamp))). Doing that will prevent MySQL from using any indexes on the timestamp column.

Selecting duplicate entries from a table and getting all the fields from the duplicate rows

I have a table like this.
id day1 day2 day3
1 411 523 223
2 413 554 245
3 417 511 209
4 420 515 232
5 422 522 212
6 483 567 212
7 456 512 256
8 433 578 209
9 438 532 234
10 418 555 223
11 460 510 263
12 453 509 245
13 441 524 233
14 430 543 261
15 456 582 222
16 444 524 241
17 478 511 211
18 421 583 222
I want to select all the IDs that have duplicate values in day2.
I'm doing
select day2,count(*) from resultater group by day having count(*)>1;
Is it possible to list all the IDs within the groups?
select day2,count(*), group_concat(id)
from resultater
group by day
having count(*)>1;
should do the trick.
