MS-Script query unable to get working or to run - sql

I am trying to create a query to show the top 24 most-viewed pages by joining 3 tables.
But, I am having trouble getting it to work. Either it has an issue with the use of UNION, JOIN or a part of the written function/script, in general.
The tables are:
+---------------+
| dbo_Good_URLs |
+---------------+
| Url |
| HTTPAlias |
| PortalID |
| page_title |
+---------------+
+-----------------+
| dbo_vw_GoodURLs |
+-----------------+
| URL |
| PortalID |
| HTTPAlias |
| Title |
+-----------------+
+-----------------------+
| dbo_analytics_history |
+-----------------------+
| URL |
| PortalId |
| HTTPAlias |
| Page_Title |
| Report_Month |
| Report_Year |
| Pageviews |
| Unique_Pageviews |
| Entrances |
| Total_Time_on_Page |
| Bounces |
| Exits |
| Avg_Time_on_Page |
| Bounce_Rate |
| Exit_Rate |
+-----------------------+
I've tried to use an IIF(Is Null(**) And I've looked through to script itself to see why UNION and JOIN seem to not work and I can't seem to figure it out.
I've been playing around with this all week and it's just not coming to me.
SELECT TOP 24 dbo_Good_URLs.Url, Nz(dbo_analytics_history.Pageviews, 0) AS Total_Pageviews,
Nz(dbo_analytics_history.Pageviews, 0) AS Month1
FROM (SELECT Url FROM dbo_Good_URLs WHERE HTTPAlias IN ('x.org', 'ab.x.org'))
UNION
SELECT Url FROM dbo_vw_GoodURLs WHERE dbo_Good_URLs.HTTPAlias IN ('x.org', 'ab.x.org')
LEFT OUTER JOIN dbo_analytics_history
ON dbo_Good_URLs.Url = dbo_analytics_history.URL AND dbo_analytics_history.HTTPAlias IN ('x.org', 'ab.x.org') AND dbo_analytics_history.Report_Month = 10
GROUP BY dbo_Good_URLs.Url, dbo_analytics_history.Pageviews
ORDER BY Nz(dbo_analytics_history.Pageviews, 0) DESC;
The result that I am looking for is for it to show the top 24 pages viewed for the month of October(I.e. month 10)

I would hazard a guess that you're actually looking for something like the following:
select top 24 q.url, nz(a.pageviews, 0) as Total_Pageviews, nz(a.pageviews, 0) as Month1
from
(
select dbo_good_urls.url from dbo_good_urls
where dbo_good_urls.httpalias in ('x.org', 'ab.x.org')
union
select dbo_vw_goodurls.url from dbo_vw_goodurls
where dbo_vw_goodurls.httpalias in ('semcog.org', 'loggedin.semcog.org')
) q
left join dbo_analytics_history a on q.url = a.url
)
where
a.report_month is null or a.report_month = 10
order by
nz(a.pageviews, 0) desc;
Here, the target URLs are selected by the two unioned subqueries, with the result of such union left joined to your dbo_analytics_history table on the url field.

Can't figure out sql join

I'm using nextcloud to track data via the forms app, the table oc_forms_v2_submissions contains the entries:
SELECT * FROM `oc_forms_v2_submissions` WHERE `form_id` = 3;
+----+---------+--------------------------------------------+------------+
| id | form_id | user_id | timestamp |
+----+---------+--------------------------------------------+------------+
| 8 | 3 | anon-user-96684f301d22e7be44f07780a9bffe06 | 1663789158 |
| 9 | 3 | anon-user-a1eaa4f939b59e00b403c046410788aa | 1663835954 |
| 10 | 3 | anon-user-440d0dbe9c107492b6ec1a06d98004a8 | 1663942458 |
+----+---------+--------------------------------------------+------------+
the second table is oc_forms_v2_answers
SELECT * FROM `oc_forms_v2_answers`;
+----+---------------+-------------+-----------------------+
| id | submission_id | question_id | text |
+----+---------------+-------------+-----------------------+
| 10 | 8 | 7 | foo |
| 11 | 9 | 7 | bar |
| 12 | 10 | 7 | foo |
+----+---------------+-------------+-----------------------+
So basically i need to the take all the id entries from table submissions and match them with submission_id from answers and I want to have the data from the text column.
SELECT oc_forms_v2_submissions.id as submission_id
FROM `oc_forms_v2_submissions`
RIGHT JOIN `oc_forms_v2_answers` ON submission_id=oc_forms_v2_answers.submission_id;
This is all i could come up with so far but that returns only the submission_id field and everything triplicated :-D
+---------------+
| submission_id |
+---------------+
| 8 |
| 8 |
| 8 |
| 9 |
| 9 |
| 9 |
| 10 |
| 10 |
| 10 |
+---------------+
Edit:
The updated query still does not get me the field from oc_forms_answers:
SELECT oc_forms_v2_submissions.id as submission_id
FROM `oc_forms_v2_submissions`
RIGHT JOIN `oc_forms_v2_answers` ON oc_forms_v2_submissions.id=oc_forms_v2_answers.submission_id where form_id="3";
that is because you are comparing to identical columns, you need in the ON Clause, the link columns of both tables
Also you can use alias, to reduce the typing time
The RIGHT JOIN would also combine all answers with thes ubmission, but you you will never have more submission as answer, so a LEFT JOIN would gove ou all submissions even if there is no answer
SELECT oc_forms_v2_submissions.id as submission_id
FROM `oc_forms_v2_submissions`
LEFT JOIN `oc_forms_v2_answers` ON oc_forms_v2_submissions.id=oc_forms_v2_answers.submission_id;
This should do the trick (just update the correct naming of columns and tables)
SELECT s.id as submission_id, a.txt FROM submissions s
LEFT JOIN answers a
ON s.id=a.submission_id;
You can check this here in db-fiddle. I've used your info for creating a DB, so WHERE clause is missing but all the rest should give you results you're after.

SQL Check if the User has IN and Out

I need help getting the User which has an 'IN' and 'Out' in Column isIN. If the user has an IN and OUT do not select them in the list. I need to select the user who has only had an IN. Please I need help. Thanks in advance.
This is the table:
| Users | IsIN |
|:------------------:|:-----:|
| MHYHDC61TMJ907867 | IN |
| MHYHDC61TMJ907867 | OUT |
| MHYHDC61TMJ907922 | IN |
| MHYHDC61TMJ907922 | OUT |
| MHYHDC61TMJ907923 | IN |
| MHYHDC61TMJ907923 | OUT |
| MHYHDC61TMJ907924 | IN | - I need to get only this row
| MHYHDC61TMJ907925 | IN |
| MHYHDC61TMJ907925 | OUT |
| MHYHDC61TMJ908054 | IN | - I need to get only this row
| MHYHDC61TMJ908096 | IN | - I need to get only this row
| MHYHDC61TMJ908109 | IN | - I need to get only this row
Need to get the result like
| Users | IsIN |
|:------------------:|:-----:|
| MHYHDC61TMJ907924 | IN |
| MHYHDC61TMJ908054 | IN |
| MHYHDC61TMJ908096 | IN |
| MHYHDC61TMJ908109 | IN |
I tried using this query and sample query below but it doesn't work.
select s.[Users], s.[isIn] [dbo].[tblIO] s
where not exists (
select 1
from [dbWBS].[dbo].[tblIO] s2
where s2.[Users] = s.[Users] and s2.isIn = 'IN'
);
You can use not exists:
select s.*
from sample s
where not exists (select 1
from sample s2
where s2.user = s.user and s2.inout = 'OUT'
);
If you want only users that meet the condition (and not the full rows):
select user
from sample s
group by user
having min(inout) = max(inout) and min(inout) = 'IN';
Bearing in mind that an 'OUT' IsIn must be always preceded by an 'IN' record, you could use a query like this:
select s.Users, 'IN' as IsIn
from sample s
group by s.Users
having count(distinct s.IsIn) = 1

SQL GROUPING with conditional

I am sure this is easy to accomplish but after spending the whole day trying I had to give up and ask for your help.
I have a table that looks like this
| PatientID | VisitId | DateOfVisit | FollowUp(Y/N) | FollowUpWks |
----------------------------------------------------------------------
| 123456789 | 2222222 | 20180802 | Y | 2 |
| 123456789 | 3333333 | 20180902 | Y | 4 |
| 234453656 | 4443232 | 20180506 | N | NULL |
| 455344243 | 2446364 | 20180618 | Y | 12 |
----------------------------------------------------------------------
Basically I have a list of PatientIDs, each patient can have multiple visits (VisitID and DateOfVisit). FollowUp(Y/N) specifies whether the patients has to be seen again and in how many weeks (FollowUpWks).
Now, what I need is a query that extracts PatientsID, DateOfVisit (the most recent one and only if FollowUp is YES) and the FollowUpWks field.
Final result should look like this
| PatientID | VisitId | DateOfVisit | FollowUp(Y/N) | FollowUpWks |
----------------------------------------------------------------------
| 123456789 | 3333333 | 20180902 | Y | 4 |
| 455344243 | 2446364 | 20180618 | Y | 12 |
----------------------------------------------------------------------
The closest I could get was with this code
SELECT PatientID,
Max(DateOfVisit) AS LastVisit
FROM mytable
WHERE FollowUp = True
GROUP BY PatientID;
The problem is that when I try adding the FollowUpWks field to the SELECT I get the following error: "The query does not include the specified expression as part of an aggregate function." However, if I add FollowUpWks to the GROUP BY statement than I get all visits, not just the most recent ones.
You need to match back to the most recent visit. One method uses a correlated subquery:
SELECT t.*
FROM mytable as t
WHERE t.FollowUp = True AND
t.DateOfVisit = (SELECT MAX(t2.DateOfVisit)
FROM mytable as t2
WHERE t2.PatientID = t.PatientID
);

SELECTing Related Rows Based on a Single Row Match

I have the following table running on Postgres SQL 9.5:
+---+------------+-------------+
|ID | trans_id | message |
+---+------------+-------------+
| 1 | 1234567 | abc123-ef |
| 2 | 1234567 | def234-gh |
| 3 | 1234567 | ghi567-ij |
| 4 | 8902345 | ced123-ef |
| 5 | 8902345 | def234-bz |
| 6 | 8902345 | ghi567-ij |
| 7 | 6789012 | abc123-ab |
| 8 | 6789012 | def234-cd |
| 9 | 6789012 | ghi567-ef |
|10 | 4567890 | abc123-ab |
|11 | 4567890 | gex890-aj |
|12 | 4567890 | ghi567-ef |
+---+------------+-------------+
I am looking for the rows for each trans_id based on a LIKE query, like this:
SELECT * FROM table
WHERE message LIKE '%def-234%'
This, of course, returns just three rows, the three that match my pattern in the message column. What I am looking for, instead, is all the rows matching that trans_id in groups of messages that match. That is, if a single row matches the pattern, get all the rows with the trans_id of that matching row.
That is, the results would be:
+---+------------+-------------+
|ID | trans_id | message |
+---+------------+-------------+
| 1 | 1234567 | abc123-ef |
| 2 | 1234567 | def234-gh |
| 3 | 1234567 | ghi567-ij |
| 4 | 8902345 | ced123-ef |
| 5 | 8902345 | def234-bz |
| 6 | 8902345 | ghi567-ij |
| 7 | 6789012 | abc123-ab |
| 8 | 6789012 | def234-cd |
| 9 | 6789012 | ghi567-ef |
+---+------------+-------------+
Notice rows 10, 11, and 12 were not SELECTed because there was not one of them that matched the %def-234% pattern.
I have tried (and failed) to write a sub-query to get the all the related rows when a single message matches a pattern:
SELECT sub.*
FROM (
SELECT DISTINCT trans_id FROM table WHERE message LIKE '%def-234%'
) sub
WHERE table.trans_id = sub.trans_id
I could easily do this with two queries, but the first query to get a list of matching trans_ids to include in a WHERE trans_id IN (<huge list of trans_ids>) clause would be very large, and would not be a very inefficient way of doing this, and I believe there exists a way to do it with a single query.
Thank you!
This will do the job I think :
WITH sub AS (
SELECT trans_id
FROM table
WHERE message LIKE '%def-234%'
)
SELECT *
FROM table JOIN sub USING (trans_id);
Hope this help.
Try this:
SELECT ID, trans_id, message
FROM (
SELECT ID, trans_id, message,
COUNT(*) FILTER (WHERE message LIKE '%def234%')
OVER (PARTITION BY trans_id) AS pattern_cnt
FROM mytable) AS t
WHERE pattern_cnt >= 1
Using a FILTER clause in the windowed version of COUNT function we can get the number of records matching the predefined pattern within each trans_id slice. The outer query uses this count to filter out irrelevant slices.
Demo here
You can do this.
WITH trans
AS
(SELECT DISTINCT trans_id
FROM t1
WHERE message LIKE '%def234%')
SELECT t1.*
FROM t1,
trans
WHERE t1.trans_id = trans.trans_id;
I think this will perform better. If you have enough data, you can do an explain on both Sub query and CTE and compare the output.

Join table condition for between 2 rows

Is it possible to join these tables:
Log table:
+--------+---------------+------------+
| name | ip | created |
+--------+---------------+------------+
| 408901 | 178.22.51.168 | 1390887682 |
| 408901 | 178.22.51.168 | 1390927059 |
| 408901 | 178.22.51.168 | 1390957854 |
+--------+---------------+------------+
Orders table:
+---------+------------+
| id | created |
+---------+------------+
| 8563863 | 1390887692 |
| 8563865 | 1390897682 |
| 8563859 | 1390917059 |
| 8563860 | 1390937059 |
| 8563879 | 1390947854 |
+---------+------------+
Result table would be:
+---------+--------------+---------+---------------+------------+
|orders.id|orders.created|logs.name| logs.ip |logs.created|
+---------+--------------+---------+---------------+------------+
| 8563863 | 1390887692 | 408901 | 178.22.51.168 | 1390887682 |
| 8563865 | 1390897682 | 408901 | 178.22.51.168 | 1390887682 |
| 8563859 | 1390917059 | 408901 | 178.22.51.168 | 1390887682 |
| 8563860 | 1390937059 | 408901 | 178.22.51.168 | 1390927059 |
| 8563879 | 1390947854 | 408901 | 178.22.51.168 | 1390927059 |
+---------+--------------+---------+---------------+------------+
Is it possible?
Espessialy, if first table is result of some query.
UPDATE
Sorry for this mistake. I want found in log who make order. So orders table relate to logs table by created field, i.e.
first row with condition (orders.created >= log.created)
This will result in a non-equi join with a horrible performance:
SELECT *
FROM t2 JOIN t1
ON t1.created =
(
SELECT MAX(t1.created)
FROM t1 WHERE t1.created <= t2.created
)
You might better go with a cursor based on a UNION like this (you probably need to add some type casts to get a working UNION):
SELECT *
FROM
(
SELECT NULL AS name, NULL AS ip, NULL AS created2, t2.*
FROM t2
UNION ALL
SELECT t1.*, NULL AS id, NULL AS created
FROM t1
) AS dt
ORDER BY COALESCE(created, created2)
Now you can process the rows in the right order and remember the rows from the last t1 row.
There is nothing to bind these 2 together.
No ID or other column exists in both tables.
If this were the case, you could join these 2 tables in a stored procedure.
At the moment you ask the first query, store the data in a newly created table, use it in the join to get your results and delete it afterwards.
Kind regards
simply you can use union
select id, created from table_2
union all
select name, ip, created from table_1
