Combine Multiple Columns And Records In MS SQL Server

Combine Multiple Columns And Records Into Comma Separated One Column In MS SQL Server. In this example i am going to describe how to combine multiple columns and records in one column in MS SQL.

Here is the scenario

I have a table having Employees names and their respective Department names,
now i want to show Employees names separated by comma into one column and respective Department name in another column.



My table schema is shown in the image below

Combine Multiple Columns And Records Sql Server

And this is Data into table



I want output in following format

                                  Department                               FirstName
                                   IT                                             amiT,Emp1,Emp5
                                  Admin                                       Shobhit, Emp3,Emp7


and so on

To get this desired result we need to write below mentioned query

SELECT DISTINCT
Department,
EmpNames = substring( ( SELECT ', ' + FirstName 
FROM Employees e2
WHERE e2.Department = e1.Department FOR XML path(''), elements 
),2,500)
FROM Employees e1

And the output of this SQL Query would be



Hope this helps

It help me. Thanks.

I've changed "substring((SELECT ...), 2,500)" to "stuff((SELECT ...), 1, 1, '')" so it's not tied to the varchar length.

substring((SELECT ...), 2,500)" to "stuff((SELECT ...), 1, 1, '')"

why not work?

please read this
Syntax:
SUBSTRING ( value_expression ,start_expression , length_expression )
your length_expression = 1

Good post. It helped me to create comma field. I put sql for above code sample:

create table emp(id int,fname varchar(50),dept varchar(50))

insert into emp values(1,'A','IT');
insert into emp values(2,'B','IT');
insert into emp values(3,'C','Sale');
insert into emp values(4,'D','Sale')

SELECT DISTINCT
Dept, EmpNames = substring( ( SELECT ', ' + Fname
FROM Emp e2
WHERE e2.Dept = e1.Dept FOR XML path(''), elements
),2,500)
FROM Emp e1

Nilesh

I Could not get the correct Result

SELECT DISTINCT
Membercode, EmpNames = substring( ( SELECT ', ' + Childname
FROM Memberchildren e2
WHERE e2.Childname = e1.Childname FOR XML path(''), elements
),1,500)
FROM Memberchildren e1 where e1.Membercode='T005'


T005 , NEWCHILDSSSS
T005 , NEWTEST234RRRRR
T005 , NEWTESTTTTTTTTTT
T005 , TEEST
T005 , TESTSSSSSSSS

Sql Query For Multiple Row To Single Column

There is also a possibility to fix this on SQL2000 or older versions (which do not have the FOR XML PATH option).
You can do this by joining the table as much times as you have multiple rows.

An example:

CREATE table #temp (col1 nvarchar(10), col2 nvarchar(1))

INSERT INTO #temp values('ComputerA', 'C')
INSERT INTO #temp values('ComputerA', 'D')
INSERT INTO #temp values('ComputerA', 'E')
INSERT INTO #temp values('ComputerB', 'C')
INSERT INTO #temp values('ComputerC', 'C')
INSERT INTO #temp values('ComputerC', 'D')


SELECT x1.col1
, REPLACE(ISNULL(MIN(x1.col2), ' ') + ', '
+ ISNULL(MIN(x2.col2), ' ') + ', '
+ ISNULL(MIN(x3.col2), ' ')
, ', ', '') AS driveletters
FROM #temp x1
LEFT JOIN #temp x2
ON x1.col1 = x2.col1
AND x2.col2 > x1.col2
LEFT JOIN #temp x3
ON x1.col1 = x3.col1
AND x3.col2 > x2.col2
GROUP BY x1.col1

DROP TABLE #temp

In this example, if you have a maximum of 26 driveletters, you have to do 25 left joins.

Hope this helps.

SELECT DISTINCT
COMPANYID, Result = substring( ( SELECT ', ' + STATUS FROM CALLLOGS e2 WHERE e2.COMPANYID = e1.COMPANYID FOR XML path(''), elements),1,500)
FROM CALLLOGS e1

This gives me a error. Can some one help me in solving this problem.

This is a neat applet; however, I'd like to see this done in SQL Server 2000. Any ideas?
