Transact SQL :: Group By Count Once For Duplicate Column Values?

Oct 1, 2015

My data is like below: 
 
ClassId ClassName   StudentId   Subject     SubjectId 
1         ESL       12         English      20 
1         ESL       13         Science     30 
1         ESL       12         Social       40 
1         ESL       12         Maths        50 
 
Required output: parameters are Subject column values 

ClassId ClassName   TotalStudents   SubjectIds  
 
1        ESL                     1              20, 40, 50 
1        ESL                     1              30 
 
When one student takes multiple subjects then count student only once, so in the above data 12 is one student id takes multiple subjects so counted only once. TotalStudents value is 1
 
I did write below query: 
 
Declare @subjectids string 
set @subjectids = '20,30,40,50' 

-- will split @subjectids  and store in temp table    

select classname, classid, Count(Distinct StudentId) 
from mytable 
where SubjectsIds in @subjectIds 
group by ClassId, ClassName, SubjectId, 
 
but it gives me below output:   

ClassId ClassName   TotalStudents   SubjectIds 
 
1        ESL        1              20 
1        ESL        1              30 
1        ESL        1              40 
1        ESL        1              50

Transact SQL :: Way To Count Changes In Value Of A Field

Oct 13, 2015

I want to avoid iterating through a table row by row and programmatically incrementing a counter,/I have define a view called Q2 with the following fields of interest:

Trial varchar(25)
BI int
Track int
CAT int

What I would like to do is partition by Trial, BI, and Track, and count the number of times CAT changes value. In Access, I would just iterate through a recordset inside a function, but I would like to see if there is a set based solution.Adding Sample Data and Output.

Trial     BI     Track     CAT
A         5      3           1

Transact SQL :: COUNT And SUM Of Multiple Columns

Sep 2, 2015

I'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](
[Installation] [numeric](38, 8) NULL,
[AccountType] [nvarchar](50) NULL,
[PWSID] [smallint] NULL,
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

Transact SQL :: Query To Retrieve Max Count

May 28, 2015

The below is my query in SQL SERVER 2012

DECLARE
@PN_INC INT,
@POSITION_DESC VARCHAR(15)
SELECT @PN_INC= MAX(PositionNumberInc) FROM dbo.tblPosition WHERE LTRIM(RTRIM(UPPER(PositionDescription)))=LTRIM(RTRIM(UPPER(@POSITION_DESC)));
SELECT @PN_INC is returning null when there is no record in the table;

1. how can I make it return 0 when @PN_INC is null else it should pick the MAX(PositionNumberInc) value

2. I have written the below query to return 0 when @PN_INC is null  but I need query to select the MAX(PositionNumberInc) value when @PN_INC is not null 

SELECT @PN_INC= coalesce(MAX(PositionNumberInc), 0) FROM dbo.tblPosition WHERE LTRIM(RTRIM(UPPER(PositionDescription)))=LTRIM(RTRIM(UPPER(@POSITION_DESC)));

Transact SQL :: Count Only Latest Entry

May 25, 2015

I have a table with below structure, with a sample entry for 1 country:

ID Date              Event CountryCode TxnID
1   22/05/2015   ABC   123   111
2   23/05/2015   XYZ   123   111
3   20/05/2015   XYZ   123   222
4   21/05/2015   ABC   123   222

So, I need to get a count like:

FOR COUNTRYCODE=123
ABC count= 1 
XYZ count= 1

Which means, I want to count for each transaction, the latest entry based on date. And there can be many countries like this. And I need to count both entries for ABC & XYZ.Normal count will give me duplicate entries.

Transact SQL :: Stored Procedure For Total Count For New Users

Jul 14, 2015

I need to create a stored procedure for total count of the user's. If  User from front end  invites other user to use my tool, that user will be stored into a table name called "test",lets say it will be stored as"Invited 1 User(s)" or if he invites 2 users it will store into table as "Invited 2 User(s)."

But now we have changed the concept to get the ISID (name of the user)  and now when ever the user invites from the front end, the user who have invited should stored in two tables "test" and " test1" table .

After we get the data into test and test1 table i need the total count of a particular user from both tables test and test1.

if i invite a user , the name of the user is getting stored in both test and test1 tables.Now i want to get the count of a user from both tables which should be 1,but its showing 2.

Reason: Why i am considering the count from 2 tables is because before we were not tracking the usernames and we were storing the count in single test table.,but now we are tracking user names and storing them in both tables(test and test1).

Here is my sample  code:

I need to sum it up to get the total user's from both the table but I should get 1 instead of 2 

SELECT
(select distinct COUNT(*) from dbo.test
where New_Values like  '%invited%'
and Created_By= 'sam'
+
(select distinct count (*)  from dbo.test1
where invited_by ='sam'

Transact SQL :: Loop On Rows - Count Of Documents For Each Supplier

I have 3 tables: Suppliers, Documents and Verification, each document may have multiple verification where I need to get the last verification according to verification date. So I just need a "Select top 1 result from Documents, Verification where doc_iddoc=ver_iddoc and result='True' order by ver_date desc" so far I get the result of the last verification, but here's the problem:

I need to get a row with the count of documents for each supplier, I mean:

Supplier Name     Docs      NegativeVerification
Acme Co                10                     1

that is I would need to loop for each supplier and each document and get the last verification, if one of any of documents have negative verification then add it to negative results. Is it possible to achieve this with a query or do I have to do it through stored procedure?
