Article title is present in KnowledgeArticleVersion table and View Normalized Score is present in KnowledgeArticleViewStat table. The parent of both tables is KnowledgeArticle, but I can't join it to KnowledgeArticleVersion, because there is no relation name present in DB schema. Of cos, I can at first execute such query
Select k.ParentId, k.NormalizedScore From KnowledgeArticleViewStat k order by k.NormalizedScore
Then
SELECT Title, UrlName, KnowledgeArticleId FROM KnowledgeArticleVersion WHERE PublishStatus='Online' AND language ='en_US' and KnowledgeArticleId in (:ids)
But my religion forbids me from executing two queries instead of one.
Maybe someone can tell me the right way to perform join in SOQL.
Assuming the k.parentIds is what you use in :ids this would work:
SELECT id,Title , UrlName, KnowledgeArticleId, PublishStatus, language
FROM KnowledgeArticleVersion
WHERE PublishStatus='Online'
AND language ='en_US'
AND KnowledgeArticleId IN (SELECT ParentId
FROM KnowledgeArticleViewStat
)

I don't get an except join to work in Cognos-11. Where or what am I missing?
Some understanding for a beginner in this branch would be nice ;-)
What I've tried so far is making two queries. The first one holds data items like "customer", "BeginningDate" and "Purpose". The second query holds data items like "customer", "Adress" and "Community".
What I'd like to accomplish is to get in query3: the "customers" from query1 that are not available in query2. To me it sounds like an except-join.
I went to the query work area, created a query3 and dragged an "except-join" icon on it. Then I dragged query1 into the upper space and query2 into the lower. What I'm used to getting with other joins, is a possibility to set a new link, cardinality and so on. Now double clicking the join isn't opening any pop-up. The properties of the except-join show "Set operation = Except", "Duplicates = remove", "Projection list = Manual".
How do I get query3 filled with the data item "customer" that only holds a list of customers which are solely appearing in query1?
In SQL terms, you want
select T2.C1
from T1
left outer join T2 on T1.C1 = T2.C1
where T2.C1 is null
So, in the query pane of a Cognos report...
Use a regular join.
Join using customer from both queries.
Change the cardinality to 1..1 on the query1 side and 0..1 on the query2 side.
In the filters for query3, add a filter for query2.customer is null.
EXCEPT is not a join. It is used to compare two data sets.

What you need is an INNER JOIN. That would be the join tool in the Toolbox in Cognos.
I have two tables, neither with a primary id. The same combination of fields uniquely identifies the records in each and makes the records between the two tables relate-able (I think).
I need a query to combine all the records from one table and only the records from the second not already included from the first table. How do I do this using 'not equal to' joins on multiple fields? My results so far only give me the records of the first table, or no records at all.
Try the following:
SELECT ECDSlides.[Supplier Code], ECDSlides.[Supplier Name], ECDSlides.Commodity
FROM ECDSlides LEFT JOIN (ECDSlides.Commodity = [Mit Task Details2].Commodity) AND (ECDSlides.[Supplier Code] = [Mit Task Details2].[Supplier Code])
WHERE [Mit Task Details2].Commodity Is Null;
This might be what you are looking for
SELECT fieldA,fieldB FROM tableA
UNION
SELECT fieldA,fieldB FROM tableB
Union should remove automatically. 'Union All' would not.
If, for some reason, you get perfect duplicates and they are not removed, you could try this :
SELECT DISTINCT * FROM (
SELECT fieldA,fieldB FROM tableA
UNION
SELECT fieldA,fieldB FROM tableB
) AS subquery
I have a sqlite database that I'm trying to build a query. The table column I need to retrieve is iEDLID from the table below :
Right now all I have to go on is a known iEventID from the table below :
And the the nClientLocationID from the table below.
So the requirements are I need to get current iEDLID to write, lookup from tblEventDateLocations for dEventDate and the tblLocation.nClientLocationID based on the tblLocations.iLocationID I already have and event selected on this screen.
So I would need a query that does a "SELECT DISTINCT table EventDateLocations.iEDLID FROM tblEventDateLocations ...."
So basically from another query I have the iEventID I need, and I have the event ID i need but where the dEventDate=(select date('now')) I need to retrieve the iEventDateID from table EventDates.iEventDateID to use on the table EventDateLocations
this is the point where I'm trying to wrap my head around the joins for this query and the syntax...
It seems like you want this:
select distinct edl.iEDLDID
from
tblEventDateLocations edl
join tblEventDates ed on edl.EventDateId = ed.EventDateId
where
ed.EventId = ?
and ed.dEventDate = date('now')
and edl.nClientLocationID = ?
where the ? of course represent the known event ID and location ID parameters.
Since nClientLocationId appears on table tblEventDateLocations you do not need to join table tblLocations unless you want to filter out results whose location ID does not appear in that table.
Good Evening,
I am using Grails and I am trying to do an HQL Query
I have an object Opportunity and inside it an object Entity and inside the Entity a collection of Titles. Each Title object can be main or not (main is a boolean field that shows which of the titles is the default one). So the query that I am doing is this:
select opportunity from Opportunity as opportunity join opportunity.entity.titles as entityTitle with entityTitle.isMain is true
But this query fails with this message:
org.hibernate.hql.ast.InvalidWithClauseException: with-clause expressions did not reference from-clause element to which the with-clause was associated.
I have tried adding the Entity and Title tables and still it fails. If I remove the with clause it works correctly but I need to filter the titles.
Thanks.
Try this query:
select distinct op from Opportunity as op
inner join op.entity as ent
inner join ent.titles as tit
with tit.isMain is true
I found the problem. First I had to join the entity to the Opportunity and then join the titles to the Opportunity. So the query is like this:
select opportunity from Opportunity as opportunity
join opportunity.entity activeEntity
with activeEntity.isActive is true
join activeEntity.titles entityTitle
with entityTitle.isActive is true
In my ETL process I am using Change Data Capture (CDC) to discover only rows that have been changed in the source tables since the last extraction. Then I do the transformation only for this rows. The problem is when I have for example 2 tables which I want to join into one dimension, and only one of them has changed. For example I have table Countries and Towns as following:
Countries:
ID Name
1 France
Towns:
ID Name Country_ID
1 Lyon 1
Now lets say a new row is added to Towns table:
ID Name Country_ID
1 Lyon 1
2 Paris 2
The Countries table has not been changed, so CDC for these tables shows me only the row from Towns table. The problem is when I do the join between Countries and Towns, there is no row in Countries change set, so the join will result in empty set.
Do you have an idea how to solve it? Of course there might be more difficult cases, involving 3 and more tables, and consequential joins.
This is a typical problem found when doing Realtime Change-Data-Capture, or even Incremental-only daily changes.
There's multiple ways to solve this.
One way would be to do your joins on the natural keys in the dimension or mapping table, to get the associated country (SELECT distinct country_name, [..other attributes..] from dim_table where country_id = X).
Another alternative would be to do the join as part of the change capture process - when a row is loaded to towns, a trigger goes off that loads the foreign key values into the associated staging tables (country, etc).
There is allot i could babble on for more information on but i will be specific to what is in your question. I would suggest the following to get the results...
1st Pass is where everything matches via the join...
Union All
2nd Pass Gets all towns where there isn't a country
(left outer join with a where condition that
requires the ID in the countries table to be null/missing).
You would default the Country ID value in that unmatched join to something designated as a "Unmatched Value" typically 0 or -1 is used or a series of standard -negative numbers that you could assign descriptions to later to identify why data is bad for your example -1 could be "Found Town Without Country".
