I have a big access database table and part of it is given below and I want to get the minimum value by group, which is the minimum value for 3, 5, 9,.... I have tried in the query using minimum value of Group by but it couldn't give me:
I want like:
Point ParaA Modvalue MinofParaA
3 0.02345610000 1.1304602327522
5 0.541734307717087 0.592591581187

9 5.5450476528689 1.034165859885
11 ….. …….
13 ……. …….
Part of my database is:

I have tried like: Group by and min (minimum value) but it doesn't give me what I want.
Based on the information provided in the comments, perhaps something along the following lines yields the result that you require:
select t.point, first(t.paraA), min(t.minofpara)
from YourTable t
group by t.point
The second column of this query essentially returns the value of a 'random' record within each point group. Change YourTable to the name of your table.
EDIT: Based on your comments to my answer, it seems that you simply require:
select t.point, min(t.paraa)
from YourTable t
group by t.point
To select the record(s) which hold this minimum, you might then use:
select t1.* from YourTable t1 inner join
(
select t2.point, min(t2.paraa) as mp
from YourTable t2
group by t2.point
) t3
on t1.point = t3.point and t1.paraa = t3.mp

I need to count the number of times that a specific string occurs but they when one ID has the same string more than once, only count it once. Basically, I need to count the number of occurrences of a string that occur uniquely to an ID. I believe this should be a simple thing to do but I don't know what I'm doing. Here is my current code:
SELECT
RXNAME as Name,
DUPERSID as ID,
COUNT(RXNAME) as Number
FROM
`OmniHealth.PrescriptionsMEPS`
GROUP BY
ID,
Name
ORDER BY
Number
When run, it says everything was counted as 1. Thanks for the help!
UPDATE:
Dataset: https://storage.googleapis.com/omnihealth/MepsPrescriptionData.csv

not sure if it is what you asked - but if you are looking for DISTINCT COUNT - go with below:
#standardSQL
SELECT
RXNAME AS Name,
COUNT(DISTINCT DUPERSID) AS Number
FROM `OmniHealth.PrescriptionsMEPS`
GROUP BY 1
ORDER BY Number DESC
Try this...You are grouping on a different field than you are counting. I think you are meaning to group by RXNAME.
SELECT
RXNAME as Name,
DUPERSID as ID,
COUNT(RXNAME) as Number
FROM
`OmniHealth.PrescriptionsMEPS`
GROUP BY
ID,
RXNAME
ORDER BY
Number
I think you want:
SELECT DUPERSID as ID, COUNT(DISTINCT RXNAME) as Number
FROM `OmniHealth.PrescriptionsMEPS`
GROUP BY ID
ORDER BY Number;
This assumes that "same string" means "same value for RXNAME".
I want to select each 5 rows to be unique and the select pattern applies for the rest of the result (i.e if the result contains 10 records I am expecting to have 2 set of 5 unique rows)
Example:
What I have:
1
1
5
3
4
5
2
4
2
3
Result I want to achieve:
1
2
3
4
5
1
2
3
4
5
I have tried and searched a lot but couldn't find anything close to what I want to achieve.
Assuming that you can somehow order the rows within the sets of 5:
SELECT t.Row % 5, t.Row FROM #T t
ORDER BY t.Row , t.Row % 5
We could probably get closer to the truth with more details about what your data looks like and what it is you're trying to actually do.
This will work with the sample of data you provided
SELECT DISTINCT(thevalue) FROM theresults
UNION ALL
SELECT DISTINCT(thevalue) FROM theresults
But it's unclear to me if it's really what you need.
For instance :
if your table/results returns 12 rows, do you still want 2x5 rows or do you want 2x6 rows ?
do you have always in your table/results the same rows in double ?
There's a lot more questions to rise and no hint about them in what you asked.
I am trying to make this very simple SQL script work:
SELECT
DATE(SEC_TO_TIMESTAMP(created_utc)) date_submission,
COUNT(*) AS num_apples_oranges_submissions
FROM
[fh-bigquery:reddit_comments.2008]
WHERE
(LOWER(body) CONTAINS ('apples')
AND LOWER(body) CONTAINS ('oranges'))
GROUP BY
date_submission
ORDER BY
date_submission
The results look like this:
1 2008-01-07 3
2 2008-01-08 1
3 2008-01-09 2
4 2008-01-10 3
5 2008-01-11 2
6 2008-01-13 2
7 2008-01-15 2
8 2008-01-16 3
As you can see, for days where there were no submissions containing both "apples" and "oranges", instead of a value of 0 being returned, the entire row is simply missing (such as on the 12th and 14th).
How can I fix this? I'm at my wits end. Thank you.
Try below, it will return all submissions days
SELECT
DATE(SEC_TO_TIMESTAMP(created_utc)) date_submission,
SUM((LOWER(body) CONTAINS ('apples') AND LOWER(body) CONTAINS ('oranges'))) AS num_apples_oranges_submissions
FROM
[fh-bigquery:reddit_comments.2008]
GROUP BY
date_submission
ORDER BY
date_submission
I have below given query which is working fine but I want to use "Not In" operator instead of "In" but its giving no results:
SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails
WHERE (((OrderProdDetails.Priority) In (SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails WHERE (((OrderProdDetails.OrdID)=[Forms]![UpdateOrder]![OdrID])))));
Desired Query:
SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails
WHERE (((OrderProdDetails.Priority) Not In (SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails WHERE (((OrderProdDetails.OrdID)=[Forms]![UpdateOrder]![OdrID])))));
Basically it is referencing a control on parent form and based on that in a subform I want to populate the priority numbers i.e 1,2,3 and if for that record 1 is entered I want to get only 2 and 3 as drop-down option.
ReocordID OrdID Brand Name Priority
2 1 Org 1 2
3 2 Org 2 1
4 1 Org 1 1
6 1 Org 1 3
7 3 Org 3 1
8 4 Org 1 1
9 5 Org 2 1
10 5 Org 2 2
11 6 Org 1 1
12 6 Org 2 2
If there is any other better approach for the same please suggest.
Thanks in advance for your help.
In all likelihood, your problem is that Priority can take on NULL values. In that case, NOT IN doesn't work as expected (although it does work technically). The usual advice is to always use NOT EXISTS with subqueries rather than NOT IN.
But, in your case, I would suggest conditional aggregation instead:
SELECT opd.Priority
FROM OrderProdDetails as opd
GROUP BY opd.Priority
HAVING SUM(IIF(opd.OrdID = [Forms]![UpdateOrder]![OdrID], 1, 0)) = 0;
The HAVING clause counts the number of times the forms OdrId is in the orders. The = 0 means it is never there. Plus, you no longer need a select distinct.
Thanks for your prompt answers however I figured out what the problem was and the answer to problem is.
SELECT DISTINCT OrderProdDetails.Priority
FROM OrderProdDetails
WHERE (((OrderProdDetails.Priority) Not In (SELECT OrderProdDetails.Priority
FROM OrderProdDetails WHERE (((OrderProdDetails.OrdID)=[Forms]![UpdateOrder]![OdrID])
and ((OrderProdDetails.Priority) Is not null) ))));
I realized that the problem was happening only to those where there was a null value in priority so I puth the check of not null and it worked fine.
Thanks
I am a long time fan of Stack Overflow but I've come across a problem that I haven't found addressed yet and need some expert help.
I have a query that is sorted chronologically with a date-time compound key (unique, never deleted) and several pieces of data. What I want to know is if there is a way to find the start (or end) of a region where a value changes? I.E.
DateTime someVal1 someVal2 someVal3 target
1 3 4 A
1 2 4 A
1 3 4 A
1 2 4 B
1 2 5 B
1 2 5 A
and my query returns rows 1, 4 and 6. It finds the change in col 5 from A to B and then from B back to A? I have tried the find duplicates method and using min and max in the totals property however it gives me the first and last overall instead of the local max and min? Any similar problems?
I didn't see any purpose for the someVal1, someVal2, and someVal3 fields, so I left them out. I used an autonumber as the primary key instead of your date/time field; but this approach should also work with your date/time primary key. This is the data in my version of your table.
pkey_field target
1 A
2 A
3 A
4 B
5 B
6 A
I used a correlated subquery to find the previous pkey_field value for each row.
SELECT
m.pkey_field,
m.target,
(SELECT Max(pkey_field)
FROM YourTable
WHERE pkey_field < m.pkey_field)
AS prev_pkey_field
FROM YourTable AS m;
Then put that in a subquery which I joined to another copy of the base table.
SELECT
sub.pkey_field,
sub.target,
sub.prev_pkey_field,
prev.target AS prev_target
FROM
(SELECT
m.pkey_field,
m.target,
(SELECT Max(pkey_field)
FROM YourTable
WHERE pkey_field < m.pkey_field)
AS prev_pkey_field
FROM YourTable AS m) AS sub
LEFT JOIN YourTable AS prev
ON sub.prev_pkey_field = prev.pkey_field
WHERE
sub.prev_pkey_field Is Null
OR prev.target <> sub.target;
This is the output from that final query.
pkey_field target prev_pkey_field prev_target
1 A
4 B 3 A
6 A 5 B
Here is a first attempt,
SELECT t1.Row, t1.target
FROM t1 WHERE (((t1.target)<>NZ((SELECT TOP 1 t2.target FROM t1 AS t2 WHERE t2.DateTimeId<t1.DateTimeId ORDER BY t2.DateTimeId DESC),"X")));
