I need to combine texts by group. I found a function called STRING_AGG.
select c.id
, c.bereichsname
, STRING_AGG(j.oberbereich,',') oberBereiches
from stellenangebote_archiv as j
join bereiche as c on j.bereich_id = c.id
group by c.id, c.bereichsname
But I am getting the following error:
STRING_AGG aggregation result exceeded the limit of 8000 bytes. Use LOB types to avoid result truncation.
Try as below
select c.id
, c.bereichsname
, STRING_AGG( CAST(j.oberbereich as nvarchar(MAX)),',') oberBereiches
from stellenangebote_archiv j
join bereiche c on j.bereich_id = c.id
group by c.id, c.bereichsname

Can someone help me fix this SQL statement? I have 2 tables... trying to get a list of all records in table 1 (c) along with a count (if any) of matching records in table 2 (cp_docs).
SELECT TOP 100 c.cal_procedure ,
c.description ,
c.active ,
c.create_user ,
c.create_date ,
c.edit_user ,
c.edit_date ,
c.id,
cp_docs.cpd
FROM cal_procedure c
OUTTER JOIN (select cal_procedure as cp, count(id) as cpd
from cal_procedure_doc
group by cal_procedure) cp_docs
ON cp_docs.cp = c.cal_procedure
Thanks,
Tracy
Hard to say without the error message but your outer join has a couple issues.
OUTER is incorrectly written at OUTTER
Your OUTER keyword needs to be prefixed with LEFT OR RIGHT. With the logic in your query you want likely want LEFT
Fixed SQL:
SELECT TOP 100 c.cal_procedure ,
c.description ,
c.active ,
c.create_user ,
c.create_date ,
c.edit_user ,
c.edit_date ,
c.id,
cp_docs.cpd
FROM cal_procedure c
LEFT OUTER JOIN (select cal_procedure as cp, count(id) as cpd
from cal_procedure_doc
group by cal_procedure) cp_docs
ON cp_docs.cp = c.cal_procedure
Now in your query, you could get null values in the cpd column if there were no values in the cal_prodcedure_doc table. If you look at Max's answer, you would get 0's instead. If you wanted to use your current approach but have the zero's display you would need to wrap cp_docs.cpd in a coalesce function
coalesce(cp_docs.cpd, 0)
In the end I think Max's answer is easier to read and probably the way I would write this query as I think it's easier to read. If the tables are huge you may want to check how each performs to see one is better than the other.
You can just add a subquery to the SELECT clause. It's cleaner than joining a temp table. If you try to read someone else's query to figure out how a calculation is done, you'll start with the SELECT statement. If the select statement points you to a table alias (e.g. cp_docs), you need to find the table in the FROM clause... etc. The execution plans are almost identical; the proposed SELECT clause subquery actually eliminates one innocuous Compute Scaler step.
SELECT c.cal_procedure ,
c.description ,
c.active ,
c.create_user ,
c.create_date ,
c.edit_user ,
c.edit_date ,
c.id,
(SELECT COUNT(*) FROM cal_procedure_docs where cal_procedure = c.cal_procedure) AS cpd
FROM cal_procedure c
Perhaps you want outer apply :
SELECT TOP 100 c.cal_procedure, c.description, c.active, c.create_user,
c.create_date, c.edit_user, c.edit_date, c.id, cp_docs.cpd
FROM cal_procedure c OUTER APPLY
(select count(id) as cpd
from cal_procedure_doc
where cal_procedure = c.cal_procedure
) cp_docs
ORDER BY ? ? ? ;
i'm using this query to select count of comments on other table but it give me error
SELECT
dbo.tblEmails.id, dbo.tblEmails.eTitle, dbo.tblEmails.ePreDesc, dbo.tblEmails.eTags, dbo.tblEmails.eFaDate, dbo.tblEmails.eViewCount,
dbo.tblEmails.ePrice, dbo.tblEmails.eImg, COUNT(tblComments.id) AS cCount
FROM
dbo.tblEmails as tblEmails
INNER JOIN
dbo.tblComments AS tblComments ON dbo.tblEmails.id = dbo.tblComments.PostID
GROUP BY
tblEmails.id, tblEmails.eTitle, tblEmails.ePreDesc, tblEmails.eTags, tblEmails.eFaDate, tblEmails.eViewCount, tblEmails.ePrice, tblEmails.eImg
UPDATE:
error is this :
the text,ntext, and image data types cannot be compared or
stored,except when using IS NULL or LIKE operator.
but i have not image data type in my table
Well, you haven't specified what error text is... But in this particular case it is easy to deduce.
Your problem is incorrect usage of aliases in join and select.
It should be not
INNER JOIN dbo.tblComments AS tblComments ON dbo.tblEmails.id = dbo.tblComments.PostID
but
INNER JOIN dbo.tblComments AS tblComments ON tblEmails.id = tblComments.PostID
And the same story is about select - not dbo.tblEmails.id but tblEmails.id since you've specified alias.
But note - using exact table_name as alias to dbo.table_name looks like a bad idea and may lead to confusion (and in fact, it has lead in your case).
Instead consider using short acronyms for aliases, like this:
SELECT
E.id, E.eTitle, E.ePreDesc, E.eTags,
E.eFaDate, E.eViewCount,E.ePrice, E.eImg,
COUNT(C.id) AS cCount
FROM dbo.tblEmails as E
INNER JOIN dbo.tblComments AS C ON E.id = C.PostID
GROUP BY
E.id, E.eTitle, E.ePreDesc, E.eTags,
E.eFaDate, E.eViewCount,E.ePrice, E.eImg
Do a sub-select to get the count:
SELECT dbo.tblEmails.id, dbo.tblEmails.eTitle, dbo.tblEmails.ePreDesc, dbo.tblEmails.eTags, dbo.tblEmails.eFaDate, dbo.tblEmails.eViewCount,
dbo.tblEmails.ePrice, dbo.tblEmails.eImg,
(select COUNT(*) from dbo.tblComments
where dbo.tblEmails.id = dbo.tblComments.PostID) AS cCount
FROM dbo.tblEmails as tblEmails
I have the following code in Ruby:
Comment.select("comments.*, COALESCE(SUM(votes.value), 0) AS rating,
user_votes.value AS user_value").
joins("LEFT JOIN votes ON votes.voteable_type = '"+type+"' AND votes.voteable_id = comments.id").
joins("LEFT JOIN votes AS user_votes ON user_votes.voteable_type = '"+type+"' AND user_votes.voteable_id = comments.id AND user_votes.user_id = #{user_id}").
where(conditions).group("comments.id").order("comments."+method).limit(limit).offset(offset)
When Rails generates this SQL query, it doesn't include the full select statement:
SELECT COUNT(*) AS count_all, comments.id AS comments_id FROM `comments`
LEFT JOIN votes ON votes.voteable_type = 'reply' AND votes.voteable_id = comments.id
LEFT JOIN votes AS user_votes ON user_votes.voteable_type = 'reply' AND
user_votes.voteable_id = comments.id AND user_votes.user_id = 1 WHERE (commentable_id =
1 AND commentable_type = 'Impression')
GROUP BY comments.id ORDER BY comments.rating DESC LIMIT 10 OFFSET 0
If I remove the group statement, however, then it properly includes the full select statement. What's going on?
select comments.* in your select statement conflicts with group by("comments.id").
Every column selected must either be in the GROUP BY clause or be contained in an aggregate function.
SQL Server shows error for SQL:
select c.* from tt_country c group by c.name
Column 'tt_country.country_id' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
ActiveRecord and arel throws out the specified select because it is ambiguous / invalid.
I must be missing something obvious but why does the following
SELECT c.ContractID, max( cs.ContractStatusCreated)
FROM dbo.NMPT_Contract AS c INNER JOIN
dbo.NMPT_ContractStatus AS cs ON c.ContractID = cs.ContractID INNER JOIN
dbo.CMSS_Status AS s ON cs.StatusID = s.StatusID
group by c.ContractID
having cs.ContractStatusCreated = MAX(cs.ContractStatusCreated)
return the following from SQL Server 2000?
Msg 8121, Level 16, State 1, Line 1 Column 'cs.ContractStatusCreated'
is invalid in the HAVING clause because it is not contained in either
an aggregate function or the GROUP BY clause.
Isn't MAX an aggregate function?
Because cs.ContractStatusCreated is not in the group-by clause, therefore it does not know where to get the data from.
And better yet, if you were to group by it you would end up with a HAVING 1=1 condition and your max(cs.ContractStatusCreated) wouldn't do what you want. I think you need a self-join or subquery to find your max value to compare to.
The error:
Msg 8121, Level 16, State 1, Line 1 Column 'cs.ContractStatusCreated' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.
MAX is aggregate function
But ContractStatusCreated is NOT in the Group By
Haven't checked this but you could write your 'max' into a subquery something like this:
select ContractID, ContractStatusCreated
FROM dbo.NMPT_Contract AS x INNER JOIN
dbo.NMPT_ContractStatus AS y ON x.ContractID = y.ContractID
where (x.ContractID, y.ContractStatusCreated) = (
SELECT c.ContractID, max( cs.ContractStatusCreated)
FROM dbo.NMPT_Contract AS c INNER JOIN
dbo.NMPT_ContractStatus AS cs ON c.ContractID = cs.ContractID INNER JOIN
dbo.CMSS_Status AS s ON cs.StatusID = s.StatusID
group by c.ContractID
)
I am trying to pull two different values based on different criteria from the same table and in my Left Join of the same table it is not recognizing the SELECT statement.
The error is as follows:
Dynamic SQL Error
SQL error code = -104
Token unknown - line 7, char -1
SELECT.
The SQL Statement:
SELECT
b.dept,b.typ,c.brand,c.style,c.ext,c.description,
max(c.price),max(c.last_cost),sum(c.quan) "TOTAL INV",D.QUAN "WEB INV"
FROM
invt c
left outer join (
SELECT dept,typ,brand,style,ext,description,sum(quan) as d.quan
FROM invt WHERE store in ('997')
group by dept,typ,brand,style,ext,description) d
on (b.store = d.store and b.style = d.style and b.brand = d.brand)
LEFT OUTER JOIN
sku b
on c.style = b.style and c.brand = b.brand
where c.quan <> 0 or c.ord <> 0
GROUP BY
b.dept,b.typ,c.brand,c.style,c.ext,c.description
Try changing this line:
SELECT dept,typ,brand,style,ext,description,sum(quan) as d.quan
to this:
SELECT store,dept,typ,brand,style,ext,description,sum(quan) as quan
You do not need the d alias here.
UPDATE:
As #Jeremy Holovacs mentioned, you also seem to be using d.store for your join but it does not exist in your subquery.
