I have three tables:
Article(idArticle,NameArt)
Tag(idTag, NameTag)
ArtiTag(idArticle,idTag)
I want to have a result like this: NameTag,Count(Articles that belongs to that tag)
I tried the following:
SELECT Tag.NameTag , COUNT(DISTINCT(idArticle))
FROM ArtiTag, ArtiTag
but it returns always only one row, even if I have many tags and many articles related
SELECT t.NameTag, COUNT(*)
FROM ArtiTag at
INNER JOIN Tag t
ON at.idTag = t.idTag
GROUP BY t.NameTag;
Select T.idTag, Max(nametag), count(artitag.idArticle) from Tag t
left join ArtiTag on t.idTag=ArtiTag.idTag
Group by t.idTag
This query outputs all tags including also tags with 0 articles.

I have a table named Ticket Numbers, which (for this example) contain the columns:
Ticket_Number
Assigned_Group
Assigned_Group_Sequence_No
Reported_Date
Each ticket number could contain 4 rows, depending on how many times the ticket changed assigned groups. Some of these rows could contain an assigned group of "Desktop Support," but some may not. Here is an example:
Example of raw data
What I am trying to accomplish is to get the an output that contains any ticket numbers that contain 'Desktop Support', but also the assigned group of the max sequence number. Here is what I am trying to accomplish with SQL:
Queried Data
I'm trying to use SQL with the following query but have no clue what I'm doing wrong:
select ih.incident_number,ih.assigned_group, incident_history2.maxseq, incident_history2.assigned_group
from incident_history_public as ih
left join
(
select max(assigned_group_seq_no) maxseq, incident_number, assigned_group
from incident_history_public
group by incident_number, assigned_group
) incident_history2
on ih.incident_number = incident_history2.incident_number
and ih.assigned_group_seq_no = incident_history2.maxseq
where ih.ASSIGNED_GROUP LIKE '%DS%'
Does anyone know what I am doing wrong?
You might want to create a proper alias for incident_history. e.g.
from incident_history as incident_history1
and
on incident_history1.ticket_number = incident_history2.ticket_number
and incident_history1.assigned_group_seq_no = incident_history2.maxseq
In my humble opinion a first error could be that I don't see any column named "incident_history2.assigned_group".
I would try to use common table expression, to get only ticket number that contains "Desktop_support":
WITH desktop as (
SELECT distinct Ticket_Number
FROM incident_history
WHERE Assigned_Group = "Desktop Support"
),
Than an Inner Join of the result with your inner table to get ticket number and maxSeq, so in a second moment you can get also the "MAXGroup":
WITH tmp AS (
SELECT i2.Ticket_Number, i2.maxseq
FROM desktop D inner join
(SELECT Ticket_number, max(assigned_group_seq_no) as maxseq
FROM incident_history
GROUP BY ticket_number) as i2
ON D.Ticket_Number = i2.Ticket_Number
)
SELECT i.Ticket_Number, i.Assigned_Group as MAX_Group, T.maxseq, i.Reported_Date
FROM tmp T inner join incident_history i
ON T.Ticket_Number = i.Ticket_Number and i.assigned_group_seq_no = T.maxseq
I think there are several different method to resolve this question, but I really hope it's helpful for you!

I have two queries. The first gives me a list of BusinessUnitIds along with a count for each:
SELECT [b].[BusinessUnitId], COUNT([b].[BusinessUnitId]) AS bucount
FROM [dbo].[ComponentTeamBusinessUnit] [b]
WHERE [b].[GlobalClientFiscalYearId] = #GlobalClientFiscalYearId
AND [b].[ComponentTeamId] IN (SELECT items FROM [dbo].[fnSplit](#ComponentTeamIds, ','))
GROUP BY [b].[BusinessUnitId])
I want to take the BusinessUnitIds in this result and join them to a second query which will retrieve the Business Unit Name associated with the BusinessUnitIds. Something like the following:
Select [c].Name, [first query result].Count from [dbo].[BusinessUnit] [c]
INNER JOIN [first query result]
WHERE [c].BusinessUnitId = [first query result].BusinessUnitId
Ultimately, what I want is a listing of Business Names, along with a count of each. I haven't been able to figure out how to do this. Can anyone help? To do both queries in a single statement would be tops. Thank you.
Exmaple:
SELECT [b].[BusinessUnitId],A.Name, COUNT([b].[BusinessUnitId]) AS bucount
FROM [dbo].[ComponentTeamBusinessUnit] [b]
LEFT JOIN NameTable as A
ON A.BusinessUnitId = b.BusinessUnitId
WHERE [b].[GlobalClientFiscalYearId] = #GlobalClientFiscalYearId
AND [b].[ComponentTeamId] IN (SELECT items FROM [dbo].[fnSplit](#ComponentTeamIds, ','))
GROUP BY [b].[BusinessUnitId],A.Name
If tables are One to One, will be neat, if one to many, you will see the result like:
id name count
1 A 5
1 B 6
And if you want to group id 1, to get:
id name count
1 A,B 11
That you need to use FOR XML PATH() together with STUFF, or STRING_SPLIT, really depends on your real case.
I have one SQL statement as:
SELECT ARTICLES.NEWS_ARTCL_ID, ARTICLES.NEWS_ARTCL_TTL_DES,
ARTICLES.NEWS_ARTCL_CNTNT_T, ARTICLES.NEWS_ARTCL_PUB_DT,
ARTICLES.NEWS_ARTCL_AUTH_NM, ARTICLES.NEWS_ARTCL_URL, ARTICLES.MEDIA_URL,
ARTICLES.ARTCL_SRC_ID, SOURCES.ARTCL_SRC_NM, MEDIA.MEDIA_TYPE_DESCRIP
FROM
RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES,
RSKLMOBILEB2E.MEDIA_TYPE MEDIA,
RSKLMOBILEB2E.ARTICLE_SOURCE SOURCES
WHERE ARTICLES.MEDIA_TYPE_IDENTIF = MEDIA.MEDIA_TYPE_IDENTIF
AND ARTICLES.ARTCL_SRC_ID = SOURCES.ARTCL_SRC_ID
AND ARTICLES.ARTCL_SRC_ID = 1
ORDER BY ARTICLES.NEWS_ARTCL_PUB_DT
Now I need to combine another SQL statement into one which is:
SELECT COUNT ( * )
FROM RSKLMOBILEB2E.NEWS_LIKES LIKES, RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
WHERE LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
Basically I have one table which contains articles and I need to include the user likes which is in another table.
Use a subquery to add the likescount in your first query like this:
SELECT ARTICLES.NEWS_ARTCL_ID
,ARTICLES.NEWS_ARTCL_TTL_DES
,ARTICLES.NEWS_ARTCL_CNTNT_T
,ARTICLES.NEWS_ARTCL_PUB_DT
,ARTICLES.NEWS_ARTCL_AUTH_NM
,ARTICLES.NEWS_ARTCL_URL
,ARTICLES.MEDIA_URL
,ARTICLES.ARTCL_SRC_ID
,SOURCES.ARTCL_SRC_NM
,MEDIA.MEDIA_TYPE_DESCRIP
,(
SELECT COUNT(*)
FROM RSKLMOBILEB2E.NEWS_LIKES LIKES
WHERE LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
) AS LikesCount
FROM RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
,RSKLMOBILEB2E.MEDIA_TYPE MEDIA
,RSKLMOBILEB2E.ARTICLE_SOURCE SOURCES
WHERE ARTICLES.MEDIA_TYPE_IDENTIF = MEDIA.MEDIA_TYPE_IDENTIF
AND ARTICLES.ARTCL_SRC_ID = SOURCES.ARTCL_SRC_ID
AND ARTICLES.ARTCL_SRC_ID = 1
ORDER BY ARTICLES.NEWS_ARTCL_PUB_DT;
I'm not sure what you are trying to achieve but it seems you want to count all the data from 2 tables. You can edit your query to something like this.
SELECT COUNT (ARTICLES.*) FROM RSKLMOBILEB2E.NEWS_LIKES LIKES
JOIN RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
ON LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
I think that solution is in using Analytic Functions. Please have a look on https://oracle-base.com/articles/misc/analytic-functions
Please check following query (keep in mind I have no idea about your table structures). Due to left join records might be duplicated, this is why grouping is added.
SELECT ARTICLES.NEWS_ARTCL_ID, ARTICLES.NEWS_ARTCL_TTL_DES,
ARTICLES.NEWS_ARTCL_CNTNT_T, ARTICLES.NEWS_ARTCL_PUB_DT,
ARTICLES.NEWS_ARTCL_AUTH_NM, ARTICLES.NEWS_ARTCL_URL, ARTICLES.MEDIA_URL,
ARTICLES.ARTCL_SRC_ID, SOURCES.ARTCL_SRC_NM, MEDIA.MEDIA_TYPE_DESCRIP,
count(LIKES.ID) over ( partition by ARTICLES.NEWS_ARTCL_ID ) as num_likes
FROM RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
join RSKLMOBILEB2E.MEDIA_TYPE MEDIA
on ARTICLES.MEDIA_TYPE_IDENTIF = MEDIA.MEDIA_TYPE_IDENTIF
join RSKLMOBILEB2E.ARTICLE_SOURCE SOURCES
on ARTICLES.ARTCL_SRC_ID = SOURCES.ARTCL_SRC_ID
LEFT JOIN RSKLMOBILEB2E.NEWS_LIKES LIKES
ON LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
WHERE
ARTICLES.ARTCL_SRC_ID = 1
group by ARTICLES.NEWS_ARTCL_ID, ARTICLES.NEWS_ARTCL_TTL_DES,
ARTICLES.NEWS_ARTCL_CNTNT_T, ARTICLES.NEWS_ARTCL_PUB_DT,
ARTICLES.NEWS_ARTCL_AUTH_NM, ARTICLES.NEWS_ARTCL_URL, ARTICLES.MEDIA_URL,
ARTICLES.ARTCL_SRC_ID, SOURCES.ARTCL_SRC_NM, MEDIA.MEDIA_TYPE_DESCRIP
ORDER BY ARTICLES.NEWS_ARTCL_PUB_DT
I also changed coma-separated list of tables from where condition to joins. I think this is more readable since table join conditions are separated from result filtering in where clause.
I have tow tables 'matches' and 'forum' I need to get match information from the matches table which has comments in the forum table so I use the following query:
SELECT distinct forum.match_static_id, matches.*
from forum
INNER JOIN matches
ON forum.match_static_id = matches.static_id
WHERE forum.comments_yes_or_no = 1
I use distinct to avoid getting the same match twice if it has more than one comment in the forum table.
The problem is I want to get the count of each match comments with the same query is it possible? I use :
SELECT distinct forum.match_static_id, count(forum.comments), matches.*
from forum
INNER JOIN matches
ON forum.match_static_id = matches.static_i
WHERE forum.comments_yes_or_no = 1
but it give me just one record (which is wrong). What is the problem ?? does I need to use group by ? and if yes where to but it in this crowded query?
Please try this:
SELECT forum.match_static_id, count(matches.id), matches.*
from forum
INNER JOIN matches
ON forum.match_static_id = matches.static_i
WHERE forum.comments_yes_or_no = 1
GROUP BY forum.id
I am struggling with combining the below Select Statments, I know I could cheat and add some fake columns in and then use Union, but I want to do this correctly.
Once I have them joined, I will be putting the Statment in to a XML file for use with Word and CRM4.
SELECT BILLTO_NAME,
BILLTO_LINE1,
BILLTO_LINE2,
BILLTO_LINE3,
BILLTO_CITY,
BILLTO_COUNTRY,
BILLTO_POSTALCODE,
ORDERNUMBER,
REQUESTDELIVERYBY,
MODIFIEDON,
SHIPTO_NAME,
SHIPTO_LINE1,
SHIPTO_LINE2,
SHIPTO_LINE3,
SHIPTO_CITY,
SHIPTO_STATEORPROVINCE,
SHIPTO_COUNTRY,
SHIPTO_POSTALCODE,
CREATEDBY
FROM SALESORDERBASE
SELECT QUANTITY,
DESCRIPTION
FROM SALESORDERDETAILBASE
SELECT NEW_ORDERNOTES,
NEW_NOTES
FROM SALESORDEREXTENSIONBASE
They all have the common column of SalesOrderID, which I need to add in somewhere as well.
You can use a LEFT JOIN on the tables:
SELECT ob.SalesOrderID
ob.BILLTO_NAME,
ob.BILLTO_LINE1,
ob.BILLTO_LINE2,
ob.BILLTO_LINE3,
ob.BILLTO_CITY,
ob.BILLTO_COUNTRY,
ob.BILLTO_POSTALCODE,
ob.ORDERNUMBER,
ob.REQUESTDELIVERYBY,
ob.MODIFIEDON,
ob.SHIPTO_NAME,
ob.SHIPTO_LINE1,
ob.SHIPTO_LINE2,
ob.SHIPTO_LINE3,
ob.SHIPTO_CITY,
ob.SHIPTO_STATEORPROVINCE,
ob.SHIPTO_COUNTRY,
ob.SHIPTO_POSTALCODE,
ob.CREATEDBY,
od.QUANTITY,
od.DESCRIPTION,
oe.NEW_ORDERNOTES,
oe.NEW_NOTES
FROM SALESORDERBASE ob
LEFT JOIN SALESORDERDETAILBASE od
on ob.SalesOrderID = od.SalesOrderID
LEFT JOIN SALESORDEREXTENSIONBASE oe
on ob.SalesOrderID = oe.SalesOrderID
Assuming the column that identifies the relationship is called id on all three tables, you can do this:
SELECT sob.BILLTO_NAME,
sob.BILLTO_LINE1,
sob.BILLTO_LINE2,
sob.BILLTO_LINE3,
sob.BILLTO_CITY,
sob.BILLTO_COUNTRY,
sob.BILLTO_POSTALCODE,
sob.ORDERNUMBER,
sob.REQUESTDELIVERYBY,
sob.MODIFIEDON,
sob.SHIPTO_NAME,
sob.SHIPTO_LINE1,
sob.SHIPTO_LINE2,
sob.SHIPTO_LINE3,
sob.SHIPTO_CITY,
sob.SHIPTO_STATEORPROVINCE,
sob.SHIPTO_COUNTRY,
sob.SHIPTO_POSTALCODE,
sob.CREATEDBY,
sodb.QUANTITY,
sodb.DESCRIPTION,
soeb.NEW_ORDERNOTES,
soeb.NEW_NOTES
From SalesOrderBase sob
JOIN SalesOrderDetailBase sodb
ON sob.id = sodb.SalesOrderID
JOIN SalesOrderExtensionBase soeb
ON sob.id = soeb.SalesOrderID
You can think of JOINing as slamming together rows side-by-side, whereas UNIONing is slamming together rows one on top of the other. UNIONS require that the columns be the same and JOINs require that there is a relationship of some kind between each row.
