I have a table say ProjectMaster:
Id ProjectName
1 A
2 B
3 C
another table ProjectMeter
Id ProjectId MeterNumber
1 1 #0001
2 1 #0002
3 1 #0003
4 2 #0004
5 2 #0005
6 3 #0006
I wish to have following output
ProjectName MeterNumbers
A #0001, #0002, #0003
B #0004, #0005
C #0006
I tried this and this, but unable to solve my problem.
I cannot use a table variable.
I have a already written Stored Procedure and it brings data from many joined tables. ProjectMaster also happens to be joined in one of these tables. Now am required to fetch data from ProjectMeter, such that, each row has concatenated ProjectMeter.MeterNumber corresponding to the ProjectId in that column.
right now, I get concatenated list of all meternumbers in all the rows.
I cannot use CURSOR, TABLE variable , Temp TABLE
( I hope still something can be done to my cause)
please help.....
Try this:
SELECT projectname, STUFF((SELECT distinct ', ' + meternumber
from projectmeter m
where p.id = m.projectid
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'') MeterNumbers
from projectmaster p
See SQL Fiddle with Demo
DECLARE #ProjectMaster AS TABLE
(
ID INT IDENTITY(1, 1) ,
ProjectName VARCHAR(2)
)
DECLARE #ProjectMeter AS TABLE
(
ID INT IDENTITY(1, 1) ,
ProjectID INT ,
MeterNumber VARCHAR(50)
)
INSERT INTO #ProjectMaster
( ProjectName )
VALUES ( 'A' )
INSERT INTO #ProjectMeter
( ProjectID, MeterNumber )
VALUES ( 1, '#0001' )
INSERT INTO #ProjectMeter
( ProjectID, MeterNumber )
VALUES ( 1, '#0002' )
SELECT pMaster.ID, STUFF(( SELECT ',' + MeterNumber
FROM #ProjectMeter
FOR
XML PATH('')
), 1, 1, '') AS 'Concat Result'
FROM #ProjectMeter pMeter
INNER JOIN #ProjectMaster pMaster ON pMaster.ID = pMeter.ProjectID
GROUP BY pMaster.ID
I have used table variables here but surely you just need to drop the #'s as I have used the same table names as you have specified? Not sure if this is okay? :)
Also in MS SQL you can do it using recursive query with CTE.
Here is a SQLFiddle demo
;with t1 as (
select t.*,
cast(meternumber as varchar(max)) as m2,
0 as level
from ProjectMeter t
where not exists
(select id
from ProjectMeter l
where l.id<t.id and l.ProjectId=t.ProjectID
)
union all
select b.*,
cast(c.m2+','+b.MeterNumber as varchar(max)) as m2,
c.level+1 as level
from ProjectMeter b
inner join t1 c
on (c.id < b.id) and (b.ProjectID=c.ProjectId)
)
select pm.ProjectName as ProjectName,
t1.m2 as MeterNumbers
from t1
inner join
(select ProjectId,max(level) ml
from t1
group by ProjectId
) t2
on (t1.ProjectId=t2.ProjectID) and (t1.level=t2.ml)
left join ProjectMaster pm
on (t1.ProjectId=pm.Id)
order by t1.ProjectID

CREATE TABLE ItemsOfStores ( Item int, Store int );
For my example above, that data would contain:
INSERT INTO ItemsOfStores (Item,Store)
VALUES (1,1),(1,3),(4,1),(4,3),(5,1),(5,3),(2,1),
(2,2),(2,4),(3,1),(3,2),(3,4);
I need the SQL to insert the results into 2 tables:
CREATE TABLE StoreGroups ( GroupId int, Store int )
CREATE TABLE ItemsOfGroups ( GroupId int, Item int )
In my example above, items 1, 4 and 5 are at stores 1 and 3, then there would be a group of
stores composed of stores 1 and 3, I'll call that group 1. So group 1 holds stores 1 and 3, so that would put (1,1),(1,3) into StoreGroups,
and the items 1, 4 and 5 are in that group, so (1,1),(1,4),(1,5) would go into ItemsOfGroups.
Also in my example, items 2 and 3 are at stores 1, 2 and 4, then there would be a second group
of stores composed of stores 1, 2 and 4, I'll call that group 2. So (2,1),(2,2),(2,4) would go into StoreGroups, and (2,2),(2,3) would go into ItemsOfGroups.
So the final results would of this small example would fill StoreGroups
with (1,1),(1,3),(2,1),(2,2),(2,4),
and ItemsOfGroups with (1,1),(1,4),(1,5),(2,2),(2,3)
I guess you want something like this.
CREATE TABLE ItemsOfStores ( Item int, Store int );
INSERT INTO ItemsOfStores (Item,Store)
VALUES (1,1),(1,3),(4,1),(4,3),(5,1),(5,3),(2,1),
(2,2),(2,4),(3,1),(3,2),(3,4);
CREATE TABLE StoreGroups ( GroupId int, Store int );
CREATE TABLE ItemsOfGroups ( GroupId int, Item int );
Insert into StoreGroups

I using SQL Server 2008 R2 / 2014. I wish to find a SQL query that can do the following:
Rules:
Each [Group] must have [Number] 1 to 6 to be complete group.
[Name] in each [Group] must be unique.
Each row only can use 1 time.
Table before sorting is...
Name Number Group
---- ------ -----
A 1
B 6
A 123
C 3
B 4
C 23
D 45
D 4
C 56
A 12
D 56
After sorting, result I want is below or similar....
Name Number Group
---- ------ -----
A 1 1
C 23 1
D 45 1
B 6 1
A 123 2
D 4 2
C 56 2
A 12 3
C 3 3
B 4 3
D 56 3
What I tried before is to find a subgroup that have [Number] consist of 1-6 with below concatenate method...
SELECT *
FROM [Table1] ST2
WHERE
SUBSTRING((SELECT ST1.[Number] AS [text()]
FROM [Table1] ST1
-- WHERE ST1.[Group] = ST2.[Group]
ORDER BY LEFT(ST1.[Number],1)
FOR XML PATH ('')), 1, 1000) = '123456'
Maybe you should check ROW_NUMBER function.
select Name
, Number
, ROW_NUMBER () OVER(PARTITION BY Name ORDER BY Number) as Group
from [Table1]
If you have more than 6 rows with same NAME value then it will return more groups. You can filter additional groups out since you are interested in only 6 groups with unique values of NAME column.
I'm not sure if this can be done more simply or not, but here's my go at it...
Advanced warning, this requires some means of splitting strings. Since you're not on 2016, I've included a function at the beginning of the script.
The bulk of the work is a recursive CTE that builds the Name and Number columns into comma delimited groups. We then reduce our working set to only the groups where the numbers would create 123456, split the groups and use ROW_NUMBER() OVER... to identify them, and then select based on the new data.

Given few strings as
SET #Codes1 = 3,4
SET #Codes2 = 1
SET #Codes3 = --empty
Table -- TblCode
Id Code
1 A
2 B
3 C
4 D
How to convert the #Codes1, #Codes2, #Codes3 with join to the table TblCode so it returns the following output :
1. #Codes1 = CD
2. #Codes2 = A
3. #Codes3 = --empty
Note that the concatenation for the output is without the comma.
PS - This is a small example to a much larger and complex data set. Kindly ignore any wrongful design pattern here.
You can try this. I added the answer just for #Codes1, but it works with #Codes2 and #Codes3 too.
DECLARE #TblCode TABLE (Id INT, Code VARCHAR(2))
INSERT INTO #TblCode
VALUES(1, 'A'),
(2,'B'),
(3,'C'),
(4,'D')
DECLARE #Codes1 VARCHAR(10) = '3,4'
DECLARE #Codes2 VARCHAR(10) = '1'
DECLARE #Codes3 VARCHAR(10) = NULL
DECLARE #CodesOut VARCHAR(10) = ''
;WITH CTE_1 AS (
SELECT CODE= #Codes1 + ','
)
, CTE_2 AS -- It silit text to rows
(
SELECT RIGHT(CTE_1.CODE, LEN(CTE_1.CODE) - CHARINDEX(',',CTE_1.CODE)) CODE , SUBSTRING(CTE_1.CODE, 0, CHARINDEX(',',CTE_1.CODE)) ID, CHARINDEX(',',CTE_1.CODE) AS CI
FROM CTE_1
UNION ALL
SELECT RIGHT(CTE_2.CODE, LEN(CTE_2.CODE) - CHARINDEX(',',CTE_2.CODE)) CODE , SUBSTRING(CTE_2.CODE, 0, CHARINDEX(',',CTE_2.CODE)) ID, CHARINDEX(',',CTE_2.CODE) AS CI
FROM CTE_2 WHERE LEN(CTE_2.CODE) > 0
)
SELECT #CodesOut = #CodesOut + C.Code FROM CTE_2 INNER JOIN #TblCode C ON CTE_2.ID = C.Id
SELECT #CodesOut
Result:
CD
You can use a recursive CTE. Here is one method:
with c as (
select c.*, row_number() over (partition by id) as seqnum
from c
),
cte as (
select cast(#codes as varchar(max)) as str,
replace(#codes, id, code) as newstr,
1 as lev
from c
where seqnum = 1
union all
select str, replace(newstr, id, code), lev + 1
from cte join
c
on c.seqnum = cte.lev + 1
)
select top (1) newstr
from cte
order by lev desc;
If there is an error in the syntax, set up a SQL Fiddle or Rextester or something similar so it can be fixed.
i have table with records :
City Name Seq
London 1
London 2
London 3
Madrid 4
London 5
Porto 6
Problem is how to get a result in string ( merge all without repeated records ).
Result : London-Madrid-London-Porto
Another option if 2012+ ... LAG()
Example
Declare #YourTable Table ([City Name] varchar(50),[Seq] int)
Insert Into #YourTable Values
('London',1)
,('London',2)
,('London',3)
,('Madrid',4)
,('London',5)
,('Porto',6)
Select Stuff((Select '-' +Value From
(
Select top 1000 Value = case when [City Name]=lag([City Name],1) over (Order By Seq) then null else [City Name] end
From #YourTable
Order By Seq
) A
For XML Path ('')),1,1,'')
Returns
London-Madrid-London-Porto
How about this?
declare #table table (CityName varchar(64), seq int)
insert into #table
values
('London',1),
('London',2),
('London',3),
('Madrid',4),
('London',5),
('Porto',6)
--find the next row that isn't the same city name (t2seq)
;with cte as(
select distinct
t.CityName
,t.seq
,min(t2.seq) as t2seq
from #table t
left join #table t2 on
t2.seq > t.seq
and t2.CityName <> t.CityName
group by
t.CityName
,t.seq),
--limit the result set to distinct list
cte2 as(
select distinct
CityName
,seq = isnull(t2seq,9999999)
from cte)
--use stuff to concat it together
select distinct
stuff(( select '-', + t2.CityName
from cte2 t2
order by seq
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')

I tried to convert the (null) values with 0 (zeros) output in PIVOT function but have no success.
Below is the table and the syntax I've tried:
SELECT
CLASS,
[AZ],
[CA],
[TX]
FROM #TEMP
PIVOT (SUM(DATA)
FOR STATE IN ([AZ], [CA], [TX])) AS PVT
ORDER BY CLASS
CLASS AZ CA TX
RICE 10 4 (null)
COIN 30 3 2
VEGIE (null) (null) 9
I tried to use the ISNULL but did not work.
PIVOT SUM(ISNULL(DATA,0)) AS QTY
What syntax do I need to use?
SELECT CLASS,
isnull([AZ],0),
isnull([CA],0),
isnull([TX],0)
FROM #TEMP
PIVOT (SUM(DATA)
FOR STATE IN ([AZ], [CA], [TX])) AS PVT
ORDER BY CLASS
If you have a situation where you are using dynamic columns in your pivot statement you could use the following:
DECLARE #cols NVARCHAR(MAX)
DECLARE #colsWithNoNulls NVARCHAR(MAX)
DECLARE #query NVARCHAR(MAX)
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(Name)
FROM Hospital
WHERE Active = 1 AND StateId IS NOT NULL
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #colsWithNoNulls = STUFF(
(
SELECT distinct ',ISNULL(' + QUOTENAME(Name) + ', ''No'') ' + QUOTENAME(Name)
FROM Hospital
WHERE Active = 1 AND StateId IS NOT NULL
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
EXEC ('
SELECT Clinician, ' + #colsWithNoNulls + '
FROM
(
SELECT DISTINCT p.FullName AS Clinician, h.Name, CASE WHEN phl.personhospitalloginid IS NOT NULL THEN ''Yes'' ELSE ''No'' END AS HasLogin
FROM Person p
INNER JOIN personlicense pl ON pl.personid = p.personid
INNER JOIN LicenseType lt on lt.licensetypeid = pl.licensetypeid
INNER JOIN licensetypegroup ltg ON ltg.licensetypegroupid = lt.licensetypegroupid
INNER JOIN Hospital h ON h.StateId = pl.StateId
LEFT JOIN PersonHospitalLogin phl ON phl.personid = p.personid AND phl.HospitalId = h.hospitalid
WHERE ltg.Name = ''RN'' AND
pl.licenseactivestatusid = 2 AND
h.Active = 1 AND
h.StateId IS NOT NULL
) AS Results
PIVOT
(
MAX(HasLogin)
FOR Name IN (' + #cols + ')
) p
')
You cannot place the IsNull() until after the data is selected so you will place the IsNull() around the final value in the SELECT:
SELECT CLASS,
IsNull([AZ], 0) as [AZ],
IsNull([CA], 0) as [CA],
IsNull([TX], 0) as [TX]
FROM #TEMP
PIVOT
(
SUM(DATA)
FOR STATE IN ([AZ], [CA], [TX])
) AS PVT
ORDER BY CLASS
Sometimes it's better to think like a parser, like T-SQL parser. While executing the statement, parser does not have any value in Pivot section and you can't have any check expression in that section. By the way, you can simply use this:
SELECT CLASS
, IsNull([AZ], 0)
, IsNull([CA], 0)
, IsNull([TX], 0)
FROM #TEMP
PIVOT (
SUM(DATA)
FOR STATE IN (
[AZ]
, [CA]
, [TX]
)
) AS PVT
ORDER BY CLASS
You have to account for all values in the pivot set. you can accomplish this using a cartesian product.
select pivoted.*
from (
select cartesian.key1, cartesian.key2, isnull(relationship.[value],'nullvalue') as [value]
from (
select k1.key1, k2.key2
from ( select distinct key1 from relationship) k1
,( select distinct key2 from relationship) k2
) cartesian
left outer join relationship on relationship.key1 = cartesian.key1 and relationship.key2 = carterisan.key2
) data
pivot (
max(data.value) for ([key2_v1], [key2_v2], [key2_v3], ...)
) pivoted
To modify the results under pivot, you can put the columns in the selected fields and then modify them accordingly. May be you can use DECODE for the columns you have built using pivot function.

I have encountered a similar problem. The root cause is that (use your scenario for my case), in the #temp table, there is no record for:
a. CLASS=RICE and STATE=TX
b. CLASS=VEGIE and (STATE=AZ or STATE=CA)
So, when MSSQL does pivot for no record, MSSQL always shows NULL for MAX, SUM, ... (aggregate functions).
None of above solutions (IsNull([AZ], 0)) works for me, but I do get ideas from these solutions.
Sorry, it really depends on the #TEMP table. I can only provide some suggestions.
Make sure #TEMP table have records for below condition, even Data is null.
a. CLASS=RICE and STATE=TX
b. CLASS=VEGIE and (STATE=AZ or STATE=CA)
You may need to use cartesian product: select A.*, B.* from A, B
In the select query for #temp, if you need to join any table with WHERE, then would better put where inside another sub select query. (Goal is 1.)
Use isnull(DATA, 0) in #TEMP table.
Before pivot, make sure you have achieved Goal 1.
I can't give an answer to the original question, since there is no enough info for #temp table. I have pasted my code as example here.
