Hi i have a table called Artikelgroep in this table there are values called Artikelgroep like 'CD''DVD' i need to show those artikelgroeps when they have 3 or more records.
So i am trying this but is isnt working
SELECT Artikelgroep FROM tblArtikel where Artikelgroep > 3
Im getting this error message
Conversion failed when converting the varchar value 'DVD' to data type int.
I think, you may need this. You need to group them together and do a count and select when count it more than 3
SELECT Artikelgroep, count(*)
FROM tblArtikel
GROUP BY Artikelgroep
HAVING count(*) > 3;
Posting the table structure would help, otherwise we have to guess it.
If my guess is correct the solution should be:
SELECT Artikelgroep,count(*) FROM tblArtikel group by Artikelgroep having count(*)>3

I have a processknowledgeentry table that has the following data:
pke_id prc_id knw_id
1 1 2
2 1 4
3 2 4
The column knw_id references another table called knowledge, which also has its own id column. I want to be able to select all knw_id values with the same prc_id, and have them retain its nature as an id (so that it remains referenceable to the knowledge table).
Desired result:
prc_id knw_ids
1 [2, 4]
My code is shown below. (It also selects a Process Name from another table called process by inner joining the prc_ids. That part works correctly at least.)
SELECT * FROM (
SELECT
p.prc_name,
(SELECT knw_id
FROM processknowledgeentry
GROUP BY knw_id
HAVING COUNT(*) > 1)
FROM processknowledgeentry pke
INNER JOIN process p
ON pke.prc_id=p.prc_id
WHERE pke.prc_id = %s) as temp
I get the error: "CardinalityViolation: more than one row returned by a subquery used as an expression", and I understand why the error exists, so I want to know how to work around it. I'm also not sure if my logic is correct.
Would appreciate any assistance, thank you!
Seems you need a STRING_AGG() function instead of GROUP_CONCAT(), which some other DBMS has, containing a string type parameter as the first argument along with HAVING clause which filters multiple prc_id values such as
SELECT p.prc_id, STRING_AGG(knw_id::TEXT,',') AS knw_ids
FROM processknowledgeentry pke
JOIN process p
ON pke.prc_id = p.prc_id
-- WHERE pke.prc_id = %s
GROUP BY p.prc_id
HAVING COUNT(pke.prc_id) > 1
Indeed this case, a WHERE clause won't be needed.

I'm trying to populate a combobox from two tables in Access (2007-2016 file format).
I have two tables:
tblSurveyStatus
SurveyID
SurveyStatus
1
Y
2
N
3
N/A
tblWorkOrder
WONumber
SurveyedID
WO2101
1
WO2102
1
WO2103
2
WO2104
3
WO2105
2
WO2106
{Empty}
WO2107
{Empty}
Desired Result:
WONumber(this col will get hidden)
SurveyStatus
WO2101
Y
WO2103
N
WO2104
N/A
This query works in the datasource for the combobox without using GROUP BY:
SELECT SurveyedID, SurveyStatus
FROM [tblWorkOrders] a
LEFT JOIN (
SELECT SurveyID, SurveyStatus
FROM [tblSurveyStatus]
) b
ON a.SurveyedID = b.SurveyID
ORDER BY b.SurveyID
The problem with this query is that it returns duplicates (Y,Y,N,N,N/A).
So I introduced the GROUP BY like this:
SELECT SurveyedID, SurveyStatus
FROM [tblWorkOrders] a
LEFT JOIN (
SELECT SurveyID, SurveyStatus
FROM [tblSurveyStatus]
) b
ON a.SurveyedID = b.SurveyID
GROUP BY a.SurveyStatus ORDER BY b.SurveyID
This causes an error message "Your query does not include the specified expression 'SurveyedID' as part of an aggregate function." So, I put MIN(SurveyedID) and the error message moves to the next field so I keep putting MIN() in the SQL until finally it works but, I get an input box asking for the "SurveyStatus" then another one asking for the "SurveyID".
I have spent three solid days researching, reading threads on this website and many others without success. I am not a programmer but I kind of understand the basics. My programming basically comes from finding snippets of code and altering them for my use. Please Help!
You are using 2 columns : SurveyedID, SurveyStatus in your 'select' expression while in 'group by' you are using only SurveyStatus which is not valid. All non-aggregate columns in select should be used in 'group by' as well. That is why by adding MIN() to those columns solved the error (which converted those non-aggregate columns to aggregate ones).
Adding "SurveyedID" also to your group by clause can resolve your issue here.
Also if your sole motive is to avoid duplicates , just use 'DISTINCT' before the list of columns in select expression
I can do this in SQL Server:
SELECT 'HERRAMIENTA ELÉCTRICA' AS TIPO_PRODUCTO,
0 AS DEPRECIACION,
(select sum(empid) from HR.employees) STOCK
but in Access the same query show me the next error:
Query input must contain at least one table or query
So which could be the best form to emulate this? Make a query with any other table looks dirty for me.
EDIT 1:, HR.employees It may no have data, but i want show constants ('HERRAMIENTA ELÉCTRICA',''0') and 0 in the third column, maybe using isnull and this is not the problem here.
Why not to select directly:
select 'HERRAMIENTA ELÉCTRICA' AS TIPO_PRODUCTO,
0 AS DEPRECIACION,
IIF(ISNULL(sum(empid)), 0, sum(empid)) AS STOCK
from HR.employees
This simply doesn't work in Access. You need a FROM clause.
So you need to have a dummy table with one record, even if you don't use a single field from that table.
SELECT 'HERRAMIENTA ELÉCTRICA' AS TIPO_PRODUCTO,
0 AS DEPRECIACION,
(select sum(empid) from HR.employees) STOCK
FROM Dummy_Table
Using this example as empty table:
with employ as
(select 2 as col from dual
minus
select 2 as col from dual)
The query is this one:
select 'HERRAM' as tipo,
0 as deprec,
coalesce(sum(col), 0) as STOCK
from employ;
coalesce(x, value) sets the column to value when X is null
In Access, you can use a system table, and Val and Nz for the zero value:
SELECT TOP 1
'HERRAMIENTA ELÉCTRICA' AS TIPO_PRODUCTO,
0 AS DEPRECIACION,
Val(Nz((select sum(empid) from HR.employees), 0)) AS STOCK
FROM
MSysObjects
I've got an aggregated query that checks if I have more than one record matching certain conditions.
SELECT RegardingObjectId, COUNT(*) FROM [CRM_MSCRM].[dbo].[AsyncOperationBase] a

and StatusCode = 10
group by RegardingObjectId
having COUNT(*) > 1
That's nice, but then there is one field in AsyncOperationBase that will be unique. Say count(*) = 3, well, AsyncOperationBaseId in AsyncOperationBase will have 3 different values since AsyncOperationBase is the table's primary key.
To be honest, I would not even know what terms and expressions to Google to find a solution.
If anyone has a solution and also, is there any words to describe what I'm looking for ? Perhaps BI people are often faced with such a requirement or something...
I could do it with an SSRS report where the report would visually do the grouping then I could expand each grouped row to get the AsyncOperationBaseId value, but simply through SQL, I can't seem to find a way out...
Thanks.

I am using the following code and getting the error below
select d.searchpack,d.context, d.day,d,txnid,d.config, c.sgtype from ds3resultstats d join
context_header c on (d.context=c.contextid) where (d.day>='2012-11-15' and d.day<='2012-11-25' and c.sgtype='Tickler' and d.config like
'%people%') GROUP BY d.context limit 10;
FAILED: Error in semantic analysis: line 1:7 Expression Not In Group By Key d
I am guessing I am using the group by incorrectly
when you use group by, you cannot select other additional field. You can only select group key with aggregate function.
See hive group by for more information.
Related questions.
Code example:
select d.context,count(*)
from ds3resultstats
...
group by d.context
or group by multiply fields.
select d.context, d.field2, count(*)
from ds3resultstats
...
group by d.context, d.field2
It is expecting all the columns to be added with group by.
Even I am facing the same issue however I managed to get a work around to these kind of issues.
you can use collect_set with the column name to get the output. For example
select d.searchpack,collect_set(d.context) from sampletable group by d.searchpack;
