Multiple Rows to single column using SQL Server - sql

I want to convert my found data to a single column
My data is
Id
------
3
4
5
that record I want to this format
id
=======
3,4,5

Try,
SELECT STUFF( (SELECT ',' + Id
FROM My_Table
ORDER BY Id
FOR XML PATH('')),
1, 1, '')

Another way
DECLARE #str VARCHAR(1000)
SELECT #str = coalesce(#str + ',', '') + a.[Your Column]
FROM (
SELECT DISTINCT [Your Column]
FROM [your Table]
) a
SELECT #str

Insert Result of Select into Variable with Order By

Data
Approval_ID
-----------

10
Query
DECLARE
#id varchar(8000)
SELECT #id = COALESCE(#id + ', ', '') + '[' + Approval_ID + ']'
FROM (
SELECT DISTINCT Approval_ID
FROM Gate_III_CS_Approval
) Y
Result always
1,10,2,3,4,5,6,7,8,9
I've tried to add Order By
ORDER BY len(Approval_ID), Approval_ID
but have error
The ORDER BY clause is invalid in views, inline functions, derived
tables, subqueries, and common table expressions, unless TOP, OFFSET
or FOR XML is also specified.
and I want to the result like this
1,2,3,4,5,6,7,8,9,10
Whats should I do?
Update :
;with cte as (
SELECT DISTINCT Approval_ID
FROM Gate_III_CS_Approval
)
SELECT #id = STUFF(
(SELECT concat(',', '[' + Approval_ID + ']')
FROM cte ORDER BY len(Approval_ID), Approval_id
FOR XML PATH('')
), 1, 1, '')
Using CTE and STUFF for XML PATH
-- replace CTE with your table, this is only an example
declare #id varchar(8000)
;with cte as (
select 1 n
union all
select n+1 n from
cte
where n < 10
)
select #id =
STUFF((
SELECT concat(',', n)
FROM cte
order by n
FOR XML PATH('')
), 1, 1, '')
select #id
programmatically cast n from alphanumeric to int for sorting
It seems you are using a varchar field instead of an integer for Approval_ID.
For ordering it based on the varchar field, you can try the method from maSTAShuFu's answer.
Here I am updating it with your query from question.
SELECT STUFF(
(SELECT CONCAT(',[', Approval_ID,']')
FROM <your_table>
ORDER BY cast(Approval_ID as int)
FOR XML PATH('')), 1, 1, '')
Maybe you can try to convert varchar to int for this purpose. I built an example here
DECLARE
#id varchar(8000)
SELECT #id = COALESCE(#id + ', ', '') + '[' + CAST(ID AS VARCHAR(10)) + ']'
FROM (
SELECT DISTINCT CAST(id AS INT) ID
FROM TABLA
) Y
SELECT #ID

Concatenate column values based on type result

Declare #name nvarchar(max),#Id int
SELECT #Id=[EmpType],#name =ISNULL(#name + ',','')+[UserName] FROM [dbo].[TestTable]
Group by [EmpType]
SELECT #Id,#name
Getting error with this code, How can i get the result employee type wise concatenated usernames
Expecting Result set
You can try below using STUFF() function
SELECT [EmpType], abc = STUFF(
(SELECT ',' + [UserName]
FROM [dbo].TestTable] t1
WHERE t1.[EmpType] = t2.[EmpType]
FOR XML PATH (''))
, 1, 1, '') from [dbo].TestTable] t2
group by [EmpType];

Replace a value in a comma separated string in SQL Server database

I'm using a SQL Server 2014 database and I have a column that contains comma-separated values such as:
1,2,3
4,5
3,6,2
4,2,8
2
What I need to do is to replace the number 2 with the number 3 (string values) in each record and not duplicate the 3 if possible. I'm not sure that this can be done unless I use a function and I'm not sure how to do it in a function.
I think I need to split a string into a table and then loop the values and put it back together with the new value. Is there an easier way? Any help is appreciated.
Expect output would therefore be:
1,3
4,5
3,6
4,3,8
3
While it is possible, I do not encourage this:
DECLARE #old AS VARCHAR(3) = '2';
DECLARE #new AS VARCHAR(3) = '3';
WITH opdata(csv) AS (
SELECT '1,22,3' UNION ALL
SELECT '1,2,3' UNION ALL
SELECT '4,5' UNION ALL
SELECT '3,6,2' UNION ALL
SELECT '4,2,8' UNION ALL
SELECT '2'
), cte1 AS (
SELECT
csv,
CASE
WHEN ',' + csv + ',' LIKE '%,' + #old + ',%' THEN
CASE
WHEN ',' + csv + ',' LIKE '%,' + #new + ',%' THEN REPLACE(',' + csv + ',', ',' + #old + ',', ',') -- new already present so just delete old
ELSE REPLACE(',' + csv + ',', ',' + #old + ',', ',' + #new + ',') -- replace old with new
END
ELSE ',' + csv + ','
END AS tmp
FROM opdata
)
SELECT
csv,
STUFF(STUFF(tmp, 1, 1, ''), LEN(tmp) - 1, 1, '') AS res
FROM cte1
Result:
csv | res
-------+-------
1,22,3 | 1,22,3
1,2,3 | 1,3
4,5 | 4,5
3,6,2 | 3,6
4,2,8 | 4,3,8
2 | 3
Note that the plethora of ',...,' is required to avoid replacing values such as 22. If you are using SQL Server 2017 you can ditch the extra CTE + STUFF and use TRIM(',' FROM ...).
This isn't going to perform particularly well, however:
WITH CTE AS (
SELECT *
FROM (VALUES ('1,2,3'),
('4,5'),
('3,6,2'),
('4,2,8'),
('2')) V(DS))
SELECT CASE WHEN DS LIKE '%3%' THEN REPLACE(REPLACE(DS,'2,',''),',2','')
WHEN DS LIKE '%2%' THEN REPLACE(DS,'2','3')
ELSE DS
END
FROM CTE;
May be you are looking something like this.
SELECT REPLACE(CASE WHEN CHARINDEX('2', '1,2,3') > 0 THEN REPLACE('1,2,3', '2','') ELSE REPLACE('1,2,3', '2','3') END, ',,',',')
I have taken a hard coded value for demonstration. You can replace'1,2,3' with column name in the table.
To update:
DECLARE #was nvarchar(2) = 2,
#willbe nvarchar(2) = 3,
#d nvarchar(1) = ','
UPDATE strings
SET string = REVERSE(
STUFF(
REVERSE(
STUFF(
CASE WHEN CHARINDEX(#d+#willbe+#d,#d+string+#d) > 0
THEN REPLACE(#d+string+#d,#d+#was+#d,#d)
ELSE REPLACE(#d+string+#d,#d+#was+#d,#d+#willbe+#d)
END,1,1,'')
),1,1,''))
Output:
1,3
4,5
3,6
4,3,8
3

Getting csv from table without any grouping SQL

I have a table that contains only two columns say Name, DepartmentId as follows
CREATE TABLE #TempDepartment
(
Name NVARCHAR(50)
,DepartmentId INT
)
INSERT INTO #TempDepartment VALUES
('ABC',1)
,('ABC2',1)
,('DEF',2)
,('XYZ',3)
I am looking to retrieve list of distinct departmentId in comma seperated format. How can I achieve this in SQL? Basically there is no common group item, hence the confusion with either using STUFF or COALESCE.
Expected output is - 1,2,3
Try this query
Select Top 1 STUFF((SELECT ', ' + CAST(DepartmentId AS Varchar(20))
FROM #TempDepartment b Group By DepartmentId
FOR XML PATH('')), 1, 2, '') CSV
From #TempDepartment
Fiddle Output
O/P :
+---------+
| CSV |
+---------|
| 1, 2, 3 |
+---------+
Try this:
;WITH CTE AS
(
SELECT DISTINCT DepartmentId
FROM #TempDepartment
)
SELECT TOP (1)
STUFF((SELECT ',' + CAST(DepartmentId AS VARCHAR(10))
FROM CTE FOR XML PATH('')), 1, 1, '')
FROM CTE
Should produce the required output:
1,2,3

Convert a row as column and merge two column as its value

I have stuck in a select statement, converting rows into columns. I have tried with PIVOT, i was able to convert the single column. But my requirement is little different. I have explained the requirement below.
I have a table structure as below,
I want to select the data as below,
The values in the table are dynamic, which is not a problem for me to deal with that. But i need a way to get the below result.
Could someone please give me a hint on doing it, may be a way to modify the PIVOT below.
select *
from
(
select TSID,AID,Count,BID
from tbl TS
WHERE TS.TPID = 1
) src
pivot
(
sum(Count)
for AID in (AID1,AID2,AID3)
) piv
Thank you..

EDIT
This will work for not previously known column names
DECLARE #Columns AS VARCHAR(MAX)
DECLARE #SQL AS VARCHAR(MAX)
SELECT #Columns = STUFF(( SELECT DISTINCT ',' + AID
FROM Table1
FOR

), 1, 1, '')
SET #SQL = '

FROM Table1 O
GROUP BY TSID,

SELECT *
