CategoryTable
Code Name
1 Food
2 Non-Food
Existing Table Consists list of category, as for example, I have two only Food and Non-Food
As challenge, I am assigning tenants with category or categories (multiple assignment, as there are tenants which are categorized as food and non-food). I i used to insert Tenant and Code to a new table creating this output
TenantAssignTable
Tenant Code
Tenant1 1,2
Tenant2 1
What I need to do, is to load the TenantAssingTable to gridview consisting the Name of the CategoryCode too like this
Desired Output
Tenant CCode Name
Tenant1 1,2 Food,Non-Food
Tenant2 1 Food
I used inner join in my code, but this is limited as I have a string of combined code in Code column.
Select a.tenant, a.ccode, b.name
from TenantAssignTable a inner join CategoryTable b
on a.CCode = b.code
Is there anyway to achieve this kind of output? I know that this is unusual in SQL coding but this is what is challenge as what the desired output is concerned and needs which is to have a multiple assignment of category to a single tenant.
Thanks in advance!
Think simple;
You can with LIKE and XML PATH
DECLARE #CategoryTable TABLE (Code VARCHAR(50), Name VARCHAR(50))
INSERT INTO #CategoryTable
VALUES
('1', 'Food'),
('2', 'Non-Food')
DECLARE #TenantAssignTable TABLE (Tenant VARCHAR(50), Code VARCHAR(50))
INSERT INTO #TenantAssignTable
VALUES
('Tenant1', '1,2'),
('Tenant2', '1')
SELECT
T.Tenant ,
T.Code,
STUFF(
(SELECT
',' + C.Name
FROM
#CategoryTable C
WHERE
',' + REPLACE(T.Code, ' ', '') + ',' LIKE '%,' + C.Code + ',%'
FOR XML PATH('')
), 1, 1, '') A
FROM
#TenantAssignTable T
Result:
Tenant Code A
--------------- ------------ ---------------
Tenant1 1,2 Food,Non-Food
Tenant2 1 Food
You can use some XML transformations:
DECLARE #x xml
SELECT #x = (
SELECT CAST('<t name="'+a.tenant +'"><a>'+REPLACE(a.code,',','</a><a>') +'</a></t>' as xml)
FROM TenantAssignTable a
FOR XML PATH('')
)
;WITH cte AS (
SELECT t.v.value('../#name','nvarchar(max)') as Tenant,
t.v.value('.','int') as CCode,
ct.Name
FROM #x.nodes('/t/a') as t(v)
INNER JOIN CategoryTable ct
ON ct.Code = t.v.value('.','int')
)
SELECT DISTINCT
c.Tenant,
STUFF((SELECT ','+CAST(CCode as nvarchar(10))
FROM cte
WHERE c.Tenant = Tenant
FOR XML PATH('')
),1,1,'') as CCode,
STUFF((SELECT ','+Name
FROM cte
WHERE c.Tenant = Tenant
FOR XML PATH('')
),1,1,'') as Name
FROM cte c
Output:
Tenant CCode Name
Tenant1 1,2 Food,Non-Food
Tenant2 1 Food
The first part (defining #x variable) will bring your table to this kind of XML:
<t name="Tenant1">
<a>1</a>
<a>2</a>
</t>
<t name="Tenant2">
<a>1</a>
</t>
Then in CTE part we join XML with table of categories. And after all get data from CTE with the help of FOR XML PATH.

Currently, I'm using the stuff function to create a comma separated list per each row.
x,y,z
What I want is to add commas for n-1 items in the list, with the final item being preceded by 'and'
x,y, and z.
For these purposes, just checking row number won't work because this list is being generated per unique Id, therefore I can't just iterate to the end of the table. Code below:
SELECT DISTINCT (sw.OwnerID)
,stuff((
SELECT DISTINCT ', ' + e.pn
FROM fct.enrtablev e
WHERE sw.OwnerID = e.OwnerId
FOR XML PATH('')), 1, 1, '') AS [Pet(s)]
A bit of a hack... AND string_agg() would be a better fit if 2017+
Here we use test the row_number() of the item count sum(1) over(), when equal this is the last item in the list
Example
Declare #YourTable table (OwnerID int,pn varchar(50))
Insert Into #YourTable values
(1,'X')
,(1,'Y')
,(1,'Z')
,(1,'Z')
,(2,'Apples')
Select Distinct
OwnerID
,stuff( ( Select case when row_number() over(order by pn) = nullif(sum(1) over() ,1)
then ', and '
else ', '
end + pn
FROM (Select distinct pn
From #YourTable
Where OwnerID = A.OwnerId
) e
Order By PN
For XML Path('')), 1, 2, '') AS [Pet(s)]
From #YourTable A
Returns
OwnerID Pet(s)
1 X, Y, and Z
2 Apples
XQUery and XML data model is based on ordered sequences. Exactly what we need.
Here is a simple solution based on XQuery and its FLWOR expression.
SQL
-- DDL and sample data population, start
DECLARE #tbl TABLE (OwnerID int, pn VARCHAR(50));
INSERT INTO #tbl (OwnerID, pn) VALUES
(1,'X'),
(1,'Y'),
(1,'Z'),
(2,'Apples');
-- DDL and sample data population, end
SELECT p.OwnerID
, (SELECT *
FROM #tbl AS c
WHERE c.OwnerID = p.OwnerID
FOR XML PATH('r'), TYPE, ROOT('root')
).query('
for $x in /root/r/pn/text()
return if ($x is (/root/r[last()]/pn/text())[1]) then
if (count(/root/r) gt 1) then concat("and ", $x) else string($x)
else concat($x, ",")
').value('.', 'VARCHAR(MAX)') AS Result
FROM #tbl AS p
GROUP BY p.OwnerID;
Output
+---------+----------------+
| OwnerID | Result |
+---------+----------------+
| 1 | X, Y, and Z |
| 2 | Apples |
+---------+----------------+
You can achieve this using ORDER BY and count.
Declare #YourTable table (OwnerID int,pn varchar(50))
Insert Into #YourTable values
(1,'X')
,(1,'Y')
,(1,'Z')
,(2,'Apples')
;WITH CTE_OwnerIdRank as
(
SELECT ownerid, pn, row_number() over (order by ownerId) as totalrn,
count(*) over(partition by ownerid order by ownerid) as ownercnt
from #yourtable
)
SELECT distinct OwnerId,
stuff((
SELECT ', ' + CASE WHEN c.totalrn = c.ownercnt then CONCAT(' and ',c.pn) else c.pn end
FROM CTE_OwnerIdRank as c
WHERE c.OwnerID = o.OwnerId
order by c.totalrn
FOR XML PATH('')), 1, 1, '') AS [Pet(s)]
from #yourtable as o
OwnerId
Pet(s)

X, Y, and Z

I have 2 strings and one integer:
#categoryID int = 163,
#Ids nvarchar(2000) = '1,2,3',
#Names nvarchar(2000) = 'Bob,Joe,Alex'
I need to select 3 columns 3 rows; The most accomplished is 3 rows 2 columns:
select #categoryID,items from FN_SplitStr(#Ids,',')
resulting:
163,1
163,2
163,3
But I can't figure out how to split both strings.
I tried many ways like:
select #categoryID,items from FN_SplitStr((#Ids,#Names),',')
select #categoryID,items from FN_SplitStr(#Ids,','),items from FN_SplitStr(#Names,',')
EXPECTED OUTPUT:
163,1,Bob
163,2,Joe
163,3,Alex
NOTE1: I looked over tens of questions the most similar is:
How to split string and insert values into table in SQL Server AND SQL Server : split multiple strings into one row each but this question is different.
NOTE2: FN_SplitStr is a function for spliting strings in SQL. And I'm trying to create a stored procedure.
Based on your expected output, you have to use cross apply twice and then create some sort of ranking to make sure that you are getting the right value. As IDs and Names don't seem to have any relationship cross apply will create multiple rows (when you split the string to Names and ID)
There might be better way but this also gives your expected output. You can change this string split to your local function.
1st Dense rank is to make sure that we get three unique names and 2nd dense rank is the rank within the name based on order by with ID and outside of the sub query you have to do some comparison to get only 3 rows.
Declare #categoryID int = 163,
#Ids nvarchar(2000) = '1,2,3',
#Names nvarchar(2000) = 'Bob,Joe,Alex'
select ConcatenatedValue, CategoryID, IDs, Names from (
select concat(#categoryID,',',a.value,',',b.value) ConcatenatedValue, #categoryID CategoryID,
A.value as IDs, b.value as Names , DENSE_RANK() over (order by b.value) as Rn,
DENSE_RANK() over (partition by b.value order by a.value) as Ranked
from string_split(#IDs,',') a
cross apply string_split(#names,',') B ) t
where Rn - Ranked = 0
Output:
Inside your stored procedure do a string split of #Ids and insert into #temp1 table with an identity(1,1) column rowed. You will get:
163,1,1
163,2,2
163,3,3
Then do the second string split of #Names and insert into #temp2 table with an identity(1,1) column rowed. You will get:
Bob,1
Joe,2
Alex,3
You can then do an inner join with #temp1 and #temp2 on #temp1.rowid = #temp2.rowid and get:
163,1,Bob
163,2,Joe
163,3,Alex
I hope this solves your problem.
You can do this with a recursive CTE:
with cte as (
select #categoryId as categoryId,
convert(varchar(max), left(#ids, charindex(',', #ids + ',') - 1)) as id,
convert(varchar(max), left(#names, charindex(',', #names + ',') - 1)) as name,
convert(varchar(max), stuff(#ids, 1, charindex(',', #ids + ','), '')) as rest_ids,
convert(varchar(max), stuff(#names, 1, charindex(',', #names + ','), '')) as rest_names
union all
select categoryId,
convert(varchar(max), left(rest_ids, charindex(',', rest_ids + ',') - 1)) as id,
convert(varchar(max), left(rest_names, charindex(',', rest_names + ',') - 1)) as name,
convert(varchar(max), stuff(rest_ids, 1, charindex(',', rest_ids + ','), '')) as rest_ids,
convert(varchar(max), stuff(rest_names, 1, charindex(',', rest_names + ','), '')) as rest_names
from cte
where rest_ids <> ''
)
select categoryid, id, name
from cte;
Here is a db<>fiddle.
You need to split CSV value with record number. For that you need to use ROW_NUMBER() function to generate record wise unique ID as column like "RID", while you split CSV columns in row.
You can use table value split function or XML as used below.
Please check this let us know your solution is found or not.
DECLARE
#categoryID int = 163,
#Ids nvarchar(2000) = '1,2,3',
#Names nvarchar(2000) = 'Bob,Joe,Alex'
SELECT
#categoryID AS categoryID,
q.Id,
w.Names
FROM
(
SELECT
ROW_NUMBER() OVER (ORDER BY f.value('.','VARCHAR(10)')) AS RID,
f.value('.','VARCHAR(10)') AS Id
FROM
(
SELECT
CAST('<a>' + REPLACE(#Ids,',','</a><a>') + '</a>' AS XML) AS idXML
) x
CROSS APPLY x.idXML.nodes('a') AS e(f)
) q
INNER JOIN
(
SELECT
ROW_NUMBER() OVER (ORDER BY h.value('.','VARCHAR(10)')) AS RID,
h.value('.','VARCHAR(10)') AS Names
FROM
(
SELECT
CAST('<a>' + REPLACE(#Names,',','</a><a>') + '</a>' AS XML) AS namesXML
) y
CROSS APPLY y.namesXML.nodes('a') AS g(h)
) w ON w.RID = q.RID
I need running Id concatenation just like running balance or total..
Concatenate the previous Ids to current Id row wise just like shown in picture
query is
with relation (Id, [orderSequence])
as
(
select Id,cast(Id as varchar(20))
from [ACChartofAccount]
union all
select p.Id, cast(Cast(r.Id as varchar) + ',' + cast(p.Id as varchar) as varchar(20))
from [ACChartofAccount] p
inner join relation r on p.ParentId = r.Id
)
select Id,orderSequence
from relation
order by orderSequence
You can use below query to get above result.
DECLARE #Table TABLE(ID VARCHAR(10));
INSERT INTO #table(ID) VALUES ('320'),(332),(333),(334),(335);
SELECT mt.ID,
STUFF((
SELECT ', ' + ID
FROM #table t
WHERE t.ID <= mt.ID
FOR XML PATH('')), 1, 2, '') AS oldersequence
FROM #table mt
ORDER BY ID
There are two tables.
One table contains:
Name value
A 1
B 2
C 3
D 4
another table contains
City value
aa 1
bb 2,3
cc 3
dd 1,2,4
I want an output which contains:
City value Name
aa 1 A
bb 2,3 B,C
cc 3 C
dd 1,2,4 A,B,D
How can i do this using cursor?
Thanks. Your question really made me appreciate normal forms.
Anyhow, I am going to go out on a limb and assume you asked for a cursor-based solution because you assumed the non-normalized data could not be handled.
Once you have the function to materialize the rows into a value list, you can solve this with a simple query.
Given:
CREATE TABLE dbo.NV (Name CHAR(1), Value INT)
CREATE TABLE dbo.CV (City varchar(88), ValueList VARCHAR(88))
loaded with the data you indicated.
And this SQL script:
GO
CREATE FUNCTION dbo.f_NVList(#VList VARCHAR(MAX)) RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #VAL VARCHAR(928)='',
#FIDescr VARCHAR(55)
SELECT #VAL = COALESCE(#VAL + LTRIM(map.name),'') + ','
FROM dbo.nv Map
WHERE CHARINDEX(','+LTRIM(STR(map.value)) + ',', ','+#VList + ',' ) > 0
SET #VAL = SUBSTRING(#VAL,1,len(#VAL)-1)
RETURN(#VAL)
END
GO -- end of function
-- this generates the output, using the function to materialize the name-values
SELECT cv.* , dbo.f_NVList(cv.ValueList ) as NameList FROM dbo.CV cv;
producing your output:
PLEASE DON'T - but If you really need the cursor for some reason, instead of
SELECT cv.* , dbo.f_NVList(cv.ValueList ) as NameList FROM dbo.CV cv;
use this
OPEN BadIdea;
FETCH NEXT FROM BadIdea INTO #C, #VList
WHILE ##FETCH_STATUS = 0
BEGIN
SET #NameList = dbo.f_NVList(#Vlist)
INSERT INTO #OUT VALUES( #C, #VLIST , #NameList )
FETCH NEXT FROM BadIdea INTO #C, #VList
END
CLOSE BadIdea
DEALLOCATE BadIdea
select * from #OUT ;
Please give a try on this:
;with nv as (
select *
from (values ('A', '1'), ('B', '2'), ('C', '3'), ('D', '4')) a (Name, value))
, cv as (
select *
from (values ('aa', '1'), ('bb', '2,3'), ('cc', '3'), ('dd', '1,2,4')) a(City, value)
)
, cv2 as (
select cv.City
, case when charindex(',',cv.value)>0 then LEFT(cv.value, charindex(',',cv.value)-1) else cv.value end value
, case when charindex(',',cv.value)>0 then right(cv.value, LEN(cv.value)-len(LEFT(cv.value, charindex(',',cv.value)-1)+',')) end leftover
from cv
union all
select cv.City
, case when charindex(',',cv.leftover)>0 then LEFT(cv.leftover, charindex(',',cv.leftover)-1) else cv.leftover end value
, case when charindex(',',cv.leftover)>0 then right(cv.leftover, LEN(cv.leftover)-len(LEFT(cv.leftover, charindex(',',cv.leftover)-1)+',')) end leftover
from cv2 cv
where cv.leftover is not null
)
select *
, stuff((
select ','+nv.Name
from cv2
join nv on nv.value=cv2.value
where cv2.City=cv.City
for xml path('')
), 1, 1, '') Name
from cv
With cv2 I split the values to City, with a recursive CTE. After that I calculate the new Name for each City.
I don't know how fast is on a big table, but I think it is better then cursor.
using CROSS APPLY we will initially delimit all the values and then we can acheieve using XML path () and CTE's
DECLARE #Name table (name varchar(5),value int)
INSERT INTO #Name (name,value)values ('A',1),('B',2),('C',3),('D',4)
DECLARE #City table (city varchar(10),value varchar(10))
INSERT INTO #City (city,value)values ('aa','1'),('bb','2,3'),('cc','3'),('dd','1,2,4')
Code :
;with CTE AS (
SELECT A.city,
Split.a.value('.', 'VARCHAR(100)') AS Data
FROM
(
SELECT city,
CAST ('<M>' + REPLACE(value, ',', '</M><M>') + '</M>' AS XML) AS Data
FROM #City
) AS A CROSS APPLY Data.nodes ('/M') AS Split(a)
),CTE2 AS (
Select c.city,t.value,STUFF((SELECT ', ' + CAST(name AS VARCHAR(10)) [text()]
FROM #Name
WHERE value = c.Data
FOR XML PATH(''), TYPE)
.value('.','NVARCHAR(MAX)'),1,2,' ') List_Output
from CTE C
INNER JOIN #Name t
ON c.Data = t.value
)
select DISTINCT c.city,STUFF((SELECT ', ' + CAST(value AS VARCHAR(10)) [text()]
FROM CTE2
WHERE city = C.city
FOR XML PATH(''), TYPE)
.value('.','NVARCHAR(MAX)'),1,2,' ') As Value ,STUFF((SELECT ', ' + CAST(List_Output AS VARCHAR(10)) [text()]
FROM CTE2
WHERE city = C.city
FOR XML PATH(''), TYPE)
.value('.','NVARCHAR(MAX)'),1,2,' ')As Name from CTE2 C
First, you need a function to split your comma-delimited values. Here is the DelimitedSplit8K written by Jeff Moden and improved by the community. This is regarded as one of the fastest SQL-based string splitter.
You should also read on FOR XML PATH(''), a method to concatenate strings. Check this article by Aaron Bertrand for more information.
SELECT
*
FROM Table2 t2
CROSS APPLY(
SELECT STUFF((
SELECT ',' + Name
FROM Table1
WHERE Value IN(
SELECT CAST(s.Item AS INT) FROM dbo.DelimitedSplit8K(t2.Value, ',') s
)
FOR XML PATH(''), type).value('.', 'VARCHAR(MAX)'
), 1, 1, '')
)x(Name)
SQL Fiddle
Notes:
Make sure to get the latest version of the DelimitedSplit8K.
For other splitter functions, check out this article by Aaron Bertrand.
I have a problem where I want to replace characters
I am using replace function but that is not giving desired output.
Values of column table_value needs to replaced with their fill names like
E - Email
P - Phone
M - Meeting
I am using this query
select table_value,
replace(replace(replace(table_value, 'M', 'MEETING'), 'E', 'EMAIL'), 'P', 'PHONE') required_value
from foobar
so second required_value row should be EMAIL,PHONE,MEETING and so on.
What should I do so that required value is correct?
The below will work (even it's not a smart solution).
select
table_value,
replace(replace(replace(replace(table_value, 'M', 'MXXTING'), 'E', 'XMAIL'), 'P', 'PHONX'), 'X', 'E') required_value
from foobar
You can do it using CTE to split the table values into E, P and M, then replace and put back together.
I assumed each record has a unique identifer Id but please replace that with whatever you have.
;WITH cte
AS
(
SELECT Id, SUBSTRING(table_value, 1, 1) AS SingleValue, 1 AS ValueIndex
FROM replacetable
UNION ALL
SELECT replacetable.Id, SUBSTRING(replacetable.table_value, cte.ValueIndex + 1, 1) AS SingleValue, cte.ValueIndex + 1 AS ValueIndex
FROM cte
INNER JOIN replacetable ON cte.ValueIndex < LEN(replacetable.table_value)
)
SELECT DISTINCT Id,
STUFF((SELECT DISTINCT ','+ CASE SingleValue
WHEN 'E' THEN 'EMAIL'
WHEN 'P' THEN 'PHONE'
WHEN 'M' THEN 'MEETING'
END
FROM cte c
WHERE c.Id = cte.Id
AND SingleValue <> ','
FOR XML PATH ('')),1,1,'')
FROM cte
Sorry , for mess code, maybe this is not best way to solve this, but what I've tried:
SET QUOTED_IDENTIFIER ON
SET ANSI_NULLS ON
GO
CREATE Function [dbo].[fn_CSVToTable]
(
#CSVList Varchar(max)
)
RETURNS #Table TABLE (ColumnData VARCHAR(100))
AS
BEGIN
DECLARE #S varchar(max),
#Split char(1),
#X xml
SELECT #Split = ','
SELECT #X = CONVERT(xml,' <root> <s>' + REPLACE(#CSVList,#Split,'</s> <s>') + '</s> </root> ')
INSERT INTO #Table
SELECT CASE RTRIM(LTRIM(T.c.value('.','varchar(20)'))) WHEN 'M' THEN 'Meeting'
WHEN 'P' THEN 'Phone'
WHEN 'E' THEN 'Email'
End
FROM #X.nodes('/root/s') T(c)
RETURN
END
GO
Then When I run this:
Select Main.table_value,
Left(Main.ColumnData,Len(Main.ColumnData)-1) As ColumnData
From
(
Select distinct tt2.table_value,
(
Select tt1.ColumnData+ ',' AS [text()]
From (
SELECT
*
FROM dbo.TestTable tt
CROSS APPLY dbo.fn_CSVToTable(tt.table_value)
) tt1
Where tt1.table_value = tt2.TABLE_value
ORDER BY tt1.table_value
For XML PATH ('')
) ColumnData
From dbo.TestTable tt2
) [Main]
I get this:
table_value ColumnData
-------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
E,P Email,Phone
E,P,M Email,Phone,Meeting
P,E Phone,Email
P,M Phone,Meeting
(4 row(s) affected)
You could also use a DECODE or CASE to translate the values.
