I want to build query to return how many rows are in this query:
select distinct c1, c2 from t1
But SQL won't accept this syntax:
select count (distinct c1, c2) from t1
Does someone know how to count multiple distinct columns? Thanks.

Hi, I have the following script segment which is failing:
CREATE TABLE #LatLong (Latitude DECIMAL, Longitude DECIMAL, PRIMARY KEY (Latitude, Longitude))
INSERT INTO #LatLong SELECT DISTINCT Latitude, Longitude FROM RGCcache
When I run it I get the following error: "Violation of PRIMARY KEY constraint 'PK__#LatLong__________7CE3D9D4'. Cannot insert duplicate key in object 'dbo.#LatLong'."
Im not sure how this is failing as when I try creating another table with 2 decimal columns and repeated values, select distinct only returns distinct pairs of values.
The failure may be related to the fact that RGCcache has about 10 million rows, but I can't see why.
Any ideas?
I am trying to just get a count of the number of distinct rows are in a table --- not looking at the entire row of fields, but only selecting a few.
i don't want to see the distinct rows, i just want a count of how many are in the table.
I have a table called Employee which have 6 columns. This table are having 1000 records. Now I want to know the distinct value count of all these 6 columns as well as normal count. like this:
ColumnName DistinctCount NormalCount
Id 1000 1000
Name 1000 1000
Phone 600 600
PINCode 200 1000
City 400 1000
Gender 2 1000
I have a CTE returning a recordset which contains a column SRC. SRC is a number which I use later to get counts and sums for the records in a distinct list.
declare@startdate date = '2014-04-01'
declare@enddate date = '2014-05-01'
; with SM as
(
SELECT --ROW_NUMBER() OVER (PARTITION BY u.SRC ORDER BY u.SRC) As Row,
u.SRC,
[Code] ....
-- If Referral start date is between our requested dates
ref.Referral_Start_Date between @startdate and @enddate
OR
-- Include referrals which started before our requested date, but are still active during our date range.
(ref.Referral_Start_Date < @startdate and (ref.Referral_End_Date > @startdate OR ref.Referral_End_Date IS NULL ))
)
INNER JOIN c_sdt s on s.Service_Delivery_Type_Id = u.Service_Delivery_Type_Id
AND s.Service_Delivery_Unit_Id = 200
)
SELECT
count(distinct (case SRC when 91 then client_number else 0 end)) As Eligable_91,

Hi,
I have a table with the following example data
idcol1col2col3
----------------------------
1abcnullnull
1abcnullnull
1null123null
4alphanullnull
4alphanullgamma
1abc987null
I would want to reduce that somehow to
idcol1col2col3
-----------------------------
1abc123null
1abc987null
4alphabetagamma
First thing in my mind was distinct over multiple columns, but I haven't found any resource mentioning that possibility.
I don't immediatly see a way without (complex) looping.
Can anybody put me on the right track?
btw, I know that Id is not an id.
It's a table var that holds an id of a table combined with fields of other tables.

View 1 Replies View RelatedI'm working on a data analysis involving a table with a large number of records (close to 2 million). I'm using only three of the columns in the table and basically am grouping results based on different criteria. The three columns are PWSID, Installation and AccountType. I have to Provide the PWSID column with a count of the total number of installations per PWSID, also a count of AccountTypes per PWSID. I have the following query, but the numbers aren't adding up and I'm not sure why. I'm falling short in the total count by around 60k records.
CREATE TABLE [dbo].[CATASTRO_PSWID_SHPMUNINEW](

Consider the following dataset:
COL1 | COL2 | COL3 | COL4
1 | FD | DR. A | Y
2 | FD | DR. A | Y
3 | FD | DR. A | N
4 | FD | DR. A | Y
5 | FD | DR. A | Y
6 | PF | DR. A | Y
7 | FD | DR. B | Y
8 | PF | DR. B | N
Consider the script below:
SELECT
COL2, COL3, COUNT(COL1) AS TOTALS
FROM CASES
GROUP BY COL2, COL3
ORDER BY COL3, COL2
The script above produces the following output:
COL2 | COL3 | TOTALS
FD | DR. A | 5
PF | DR. A | 1
FD | DR. B | 1
PF | DR. B | 1
I need to add one more column to the script that counts records with 'Y' in COL4 for each COL1 category (FD, PF). The final dataset would look like this:
COL2 | COL3 | TOTALS | NEWCOL
FD | DR. A | 5 | 4
PF | DR. A | 1 | 1
FD | DR. B | 1 | 1
PF | DR. B | 1 | 0

hi all,
sometimes, when tables are poorly joined, we have exactly same rows as a result.. so we use distinct.. but how can we count(*) the distinct rows?
select distinct d.docrefid from tbljobDocuments d
left join tbljobitems j on j.docrefid=d.docrefid
where d.docrefid='DC01C06027' and j.itemid='39J1667-H86700'
will return me
docrefid
DC01C06027
but when i try to count(*) only the distinct record, it count all..
select distinct d.docrefid, count(*) from tbljobDocuments d
left join tbljobitems j on j.docrefid=d.docrefid
where d.docrefid='DC01C06027' and j.itemid='39J1667-H86700'
group by d.docrefid
will return me
DocrefId Count
DC01C060272
when i expect
DocrefId Count
DC01C060271

Hi
I have a table which stores the shift information for employees. The table contains 10 columns as Employeename,Employeeno,month,year,shifttimings etc. If an employee works a day in a particular shift, then a row will be inserted in to the above table for that employee.
Now at the end of the month i wanted to calculate the shift details for each employee for a particular month of a given year like employeename,employeeno, noofdays(countof shiftdays).
Can some body help?
Thanks in Advance!

I have an SQL statement that looks like the following:
SELECT [Docs-Entities].entityID, entityName, COUNT([Docs-DocsEntities].filename) AS numDocs
FROM [Docs-Entities] LEFT JOIN [Docs-DocsEntities]
ON [Docs-Entities].entityID = [Docs-DocsEntities].entityID
GROUP BY [Docs-Entities].entityID, entityName
but the problem is that numDocs (the COUNT) is not returning a distinct count. In the DocEntities table, a particular document can actually have multiple entries with the same entityID so that produces inflated numbers for numDocs. But when I do a SELECT DISTINCT on a particular entityID, the results are less and don't match the numDocs number because I only need to list the document one time. This is not a huge issue, but it looks bad on my site.
Is there a way that I can make COUNT count distinctly?
Thanks for the help and I hope I worded that cllearly...

View 3 Replies View RelatedHi,
I want a count of distinct rows in a table through a single query -- is it possible?
eg.
table-
create table ch1 (a int, b int, c int, d int)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,3,4,5)
Here distinct row count in a table is 3 which I want to achieve thro a query.
if I do
select count(distinct a) from ch1 it works fine and gives me output as 2.
but this is not working
select count(distinct a,b,c,d) from ch1 - any workaround to find the distinct row count in a table??
Please reply.
Cheers!

hello,
i have a working stored procedure SELECT CommentID, UserName, PictureID, DateCommented, COUNT(CommentID) OVER (PARTITION BY PictureID) AS 'NrOfComments'
FROM Comments WHERE PictureID = @PictureID
witch returns among others the number of comments for a picture
i need to select the number of distinct users who commented that user too, so i added this at SELECT statement, COUNT(DISTINCT UserName) AS 'Expr1'
i get that error:
"Colum 'Comments.CommentID' is invalig in the select list beacuse it is not contained in either an aggregate function or the GROUP BY clause."
what should i do, to select the number of distinct users who commented on a specific picture?
here are the table rows, if you need that
CommentID --- UserName --- PictureID --- DateCommented
please help me, thank you
It doesn't seem possibly, but maybe?
Is there a way to have an expression be used, but also benefit from using distinct on a column?
I'm looking for something like:
sum(case when dtEntered > '1-1-2006' then 1 else 0 end)
but also encorporating somehow a distinct count on UserName. So a username showing twice would only count once, and this would only be counted if the record's dtEntered date was greater than Jan 1, 2006.
The reason I'm writing the statement that way is because there are 5 columns which aggregate data by different time periods.
If it's not possible, I will just end up joining to the table multiple times, putting the date filter in the where clause.
I am trying to get the below query to work and can't seem to get past this error. Not sure but everywhere I look I think my syntax is right. I am probably missing something obvious but I'm just back from vacation and trying to get in the swing of things. Any help would be appreciated.
