I have a dynamic select query which supposed to fetches columns as col1, col2......col9, col10 but it fetches incorrectly as col1, col10, col11, col12, col2.... Not sure how to select them as the query is dynamic.
Please help.
This is the dynamic select I have been using.

If you are using COALESCE or STUFF to build your columns, make sure there is an ORDER by
Furthermore, you could have col01,col02,..col10 to ensure the sequence

I have a table that has many InsuranceNo's for unique MemberIDs. If there are more than one InsuranceNo, I want the InsuranceNo's to shift to a column, so in the end there is one line per MemberID, with all the iterations of that ID's InsuranceNo's as a Column.
MemberID InsuranceNo
--------------------------
123456 dser
124571 jklh
123456 abcd
I want it to look like this:
MemberID InsuranceNo1 InsuranceNo2
-----------------------------------------------------
123456 dser abcd
124571 jklh
Thank you!
Yet another option... Just change "YourTable" to your actual table name.
Example
Declare #SQL varchar(max) = '
Select *
From (
Select MemberID
,Item = concat(''InsuranceNo'',row_number() over (Partition By MemberID Order By (Select NULL)))
,Value = InsuranceNo
From YourTable
) A
Pivot (max([Value]) For [Item] in (' + Stuff((Select ','+QuoteName(concat('InsuranceNo',ColNr))
From (Select Distinct ColNr=row_number() over (Partition By MemberID Order By (Select NULL)) from YourTable ) A
For XML Path('')),1,1,'') + ') ) p'
--Print #SQL
Exec(#SQL);
Returns
MemberID InsuranceNo1 InsuranceNo2
123456 dser abcd
124571 jklh NULL
If it helps wrap your head around PIVOT, the SQL Generated looks like this:
Select *
From (
Select MemberID
,Item = concat('InsuranceNo',row_number() over (Partition By MemberID Order By (Select NULL)))
,Value = InsuranceNo
From YourTable
) A
Pivot (max([Value]) For [Item] in ([InsuranceNo1],[InsuranceNo2]) ) p
I prefer a dynamic cross tab to the dynamic pivot. I find the syntax far less obtuse and it is super easy if you need to add additional columns. Here is I would go about tackling this. Of course in your case you don't need a temp table because you have an actual table to use.
if OBJECT_ID('tempdb..#Something') is not null
drop table #Something
create table #Something
(
MemberID int
, InsuranceNo varchar(10)
)
insert #Something values
(123456, 'dser')
, (124571, 'jklh')
, (123456, 'abcd')
declare #StaticPortion nvarchar(2000) =
'with OrderedResults as
(
select *, ROW_NUMBER() over(partition by MemberID order by InsuranceNo) as RowNum
from #Something
)
select MemberID';
declare #DynamicPortion nvarchar(max) = '';
declare #FinalStaticPortion nvarchar(2000) = ' from OrderedResults Group by MemberID order by MemberID';
with E1(N) AS (select 1 from (values (1),(1),(1),(1),(1),(1),(1),(1),(1),(1))dt(n)),
E2(N) AS (SELECT 1 FROM E1 a, E1 b), --10E+2 or 100 rows
cteTally(N) AS
(
SELECT ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM E2
)
select #DynamicPortion = #DynamicPortion +
', MAX(Case when RowNum = ' + CAST(N as varchar(6)) + ' then InsuranceNo end) as InsuranceNo' + CAST(N as varchar(6)) + CHAR(10)
from cteTally t
where t.N <=
(
select top 1 Count(*)
from #Something
group by MemberID
order by COUNT(*) desc
)
select #StaticPortion + #DynamicPortion + #FinalStaticPortion
declare #SqlToExecute nvarchar(max) = #StaticPortion + #DynamicPortion + #FinalStaticPortion;
exec sp_executesql #SqlToExecute
I am using Dynamic PIVOT approach to convert the dynamic rows into columns and its working fine for me. But I have one more requirement on top of it. I am using below query:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ','
+ QUOTENAME(case when d.col = 'STN_CODE' then col+'_'+cast(seq as varchar(10))
else col+'_'+cast(seq as varchar(10)) end)
from ( select row_number() over(partition by POF_FILE_ID,
PART_PFX,
PART_BASE,PART_SFX
order by STN_CODE,PROCESS_ELEMENT) seq
from APT_POINT_OF_FIT
) t
cross apply
(
select 'STN_CODE', 1 union all
select 'PROCESS_ELEMENT', 2
) d (col, so)
group by col, so, seq
order by seq, so
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT POF_FILE_ID,PART_PFX,PART_BASE,PART_SFX, ' +
#cols + '
from
(
select t.POF_FILE_ID,t.PART_PFX,t.PART_BASE,t.PART_SFX,
col = case
when c.col = ''STN_CODE'' then col+''_''+cast(seq as varchar(10))
else col+''_''+cast(seq as varchar(10))
end,
value
from
(
select POF_FILE_ID,PART_PFX,PART_BASE,PART_SFX,STN_CODE,
PROCESS_ELEMENT,
row_number() over(partition by POF_FILE_ID,
PART_PFX,
PART_BASE,
PART_SFX
order by STN_CODE) seq
from APT_POINT_OF_FIT
) t
cross apply
(
select ''STN_CODE'', STN_CODE union all
select ''PROCESS_ELEMENT'', PROCESS_ELEMENT
) c (col, value)
) x
pivot
(
max(value)
for col in (' + #cols + ')
) p '
execute sp_executesql #query;
My requirement is to insert the values in separate columns till seq 8 and concatenate all other column values coming after that seq(> seq8).
Any help would be appreciated.
Thanks!
I have a table and values as shown here
create table #example(id int primary key identity, cols varchar(255))
insert into #example(cols) values('HI,HELLO,BYE,TC')
insert into #example(cols) values('WHAT,ARE,YOU,DOING,HERE')
I need the resultant output as shown in the picture
Note : There is no limit for values i.e dynamic
This is what you are expecting
Schema:
CREATE TABLE #EXAMPLE(ID INT PRIMARY KEY IDENTITY, COLS VARCHAR(255))
INSERT INTO #EXAMPLE(COLS) VALUES('HI,HELLO,BYE,TC')
INSERT INTO #EXAMPLE(COLS) VALUES('WHAT,ARE,YOU,DOING,HERE')
Do split those comma separated values into Rows and Apply pivot
SELECT * FROM (
SELECT id
, ROW_NUMBER() OVER(PARTITION BY ID ORDER BY (SELECT 1)) AS ID2
, SPLT.CLMS.value('.','VARCHAR(MAX)') AS LIST FROM (
select id
, CAST( '<M>'+REPLACE(cols,',','</M><M>')+'</M>' AS XML) AS XML_COL from #example E
)E
CROSS APPLY E.XML_COL.nodes('/M') AS SPLT(CLMS)
)A
PIVOT
(
MAX(LIST) FOR ID2 IN ([1],[2],[3],[4],[5])
)PV
You will get result as
+----+------+-------+-----+-------+------+
| id | 1 | 2 | 3 | 4 | 5 |
+----+------+-------+-----+-------+------+
| 1 | HI | HELLO | BYE | TC | NULL |
| 2 | WHAT | ARE | YOU | DOING | HERE |
+----+------+-------+-----+-------+------+
Edit:
And now you need to go for dynamic pivot,since There is no limit for values.
DECLARE #COLS VARCHAR(MAX)='', #QRY VARCHAR(MAX)='';
SELECT #COLS =#COLS+'['+CAST( ID2 AS VARCHAR(10))+'],' FROM (
SELECT DISTINCT ROW_NUMBER() OVER(PARTITION BY ID ORDER BY (SELECT 1)) AS ID2 FROM (
select id, CAST( '<M>'+REPLACE(cols,',','</M><M>')+'</M>' AS XML) AS XML_COL from #example E
)E
CROSS APPLY E.XML_COL.nodes('/M') AS SPLT(CLMS)
)A
SELECT #COLS = LEFT(#COLS,LEN(#COLS)-1)
SELECT #QRY =
'
SELECT * FROM (
SELECT id
, ROW_NUMBER() OVER(PARTITION BY ID ORDER BY (SELECT 1)) AS ID2
, SPLT.CLMS.value(''.'',''VARCHAR(MAX)'') AS LIST FROM (
select id, CAST( ''<M>''+REPLACE(cols,'','',''</M><M>'')+''</M>'' AS XML) AS XML_COL from #example E
)E
CROSS APPLY E.XML_COL.nodes(''/M'') AS SPLT(CLMS)
)A
PIVOT
(
MAX(LIST) FOR ID2 IN ('+#COLS+ ')
)PV'
EXEC( #QRY)
Dynamic version base on split string then pivot table
Schema:
create table #example(id int primary key identity, cols varchar(255))
insert into #example(cols) values('HI,HELLO,BYE,TC')
insert into #example(cols) values('WHAT,ARE,YOU,DOING,HERE')

I have a table with column and values as below
How do I fetch the result as in the second tabular column with the DYNAMIC column names as -- first with "prgmg_product_id" and the rest of the column as "source ID 1","source ID 2", "source ID 3"
To achieve this using Dynamic SQL, the below will help:
CREATE TABLE #Prgmg (
prgmg_product_id INT
,source_id_other INT
);
INSERT #Prgmg (
prgmg_product_id
,source_id_other
)
VALUES (3310,11478)
,(3337,10833)
,(3354,11466)
,(4039,4846)
,(4039,65454)
,(4039,65456);
DECLARE #DYColumns NVARCHAR(1000)
,#DYSqlQuery NVARCHAR(4000);
-- CREATE THE COLUMNS REQUIRED
SET #DYColumns = STUFF((
SELECT DISTINCT ','
+ N'sourceID'
+ CAST(ROW_NUMBER() OVER (PARTITION BY prgmg_product_id ORDER BY prgmg_product_id, source_id_other) AS NVARCHAR(10))
FROM #Prgmg
FOR XML PATH('')
), 1, 1, '');
-- CREATE THE DYNAMIC SQL AND ADD IN THE CREATED COLUMNS
SET #DYSqlQuery = '
SELECT prgmg_product_id,'
+ #DYColumns
+ ' FROM (
SELECT prgmg_product_id
,CAST(N''sourceID'' + CAST(ROW_NUMBER() OVER (
PARTITION BY prgmg_product_id ORDER BY prgmg_product_id, source_id_other
) AS NVARCHAR(10)) AS NVARCHAR(100)) AS Col
,source_id_other
FROM #Prgmg S1
) X
PIVOT(MIN(source_id_other) FOR Col IN (' + #DYColumns + ')) P'
EXECUTE sp_executesql #DYSqlQuery;
Whilst this does offer you the solution, you should spend time understanding the concepts used. Such as the creation of the Columns required using ROW_NUMBER and the how that maps to the use of the PIVOT.
I had a little time to I tossed this together. I know that around SO the preference is to use a dynamic pivot. I do not much care for PIVOT in sql server. I find the syntax to be very obtuse. I tend to prefer a cross tab query (also known as conditional aggregation) instead. The added benefit is that this approach is almost always slightly quicker than a dynamic PIVOT.
You also have to realize that more than half of the code posted here is setting up the problem. In the future you should post ddl and sample data in a consumable format like this. It makes it so much easier for us to help.
if OBJECT_ID('tempdb..#Something') is not null
drop table #Something

prgmg_product_id int,

I am trying to convert column to rows. I am beginner to PIVOT. Tried below code but error is coming as 'Error converting data type nvarchar to datetime.
The incorrect value "Tot_GPS_Cnt" is supplied in the PIVOT operator.'
CREATE TABLE #tbl_Res1
(
CallDate DATETIME,
Tot_GPS_Cnt INT,
Tot_GND_Cnt INT,
Per_Ratio NUMERIC(10,2)
)
INSERT INTO #tbl_Res1
SELECT '2015-04-24 00:00:00.000','40','26','65.00' UNION ALL
SELECT '2015-04-25 00:00:00.000','22','14','63.64' UNION ALL
SELECT'2015-04-26 00:00:00.000','27','21','77.78' UNION ALL
SELECT'2015-04-27 00:00:00.000','41','23','56.10'
Source Table
Desired Output
I have tried with below query bu failing. Please help. Thanks in advance
SELECT CallDate=col, Tot_GPS_Cnt, Tot_GND_Cnt, Per_Ratio
FROM
( select CallDate, col, value from #tbl_Res1
cross apply
(
SELECT 'Tot_GPS_Cnt',cast(Tot_GPS_Cnt as varchar(10)) UNION ALL
SELECT 'Tot_GND_Cnt', cast(Tot_GND_Cnt as varchar(10)) UNION ALL
SELECT 'Per_Ratio', cast(Per_Ratio as varchar(10))
) c (col,value)
) d
PIVOT
(
max(value) for CallDate in ([Tot_GPS_Cnt], [Tot_GND_Cnt], [Per_Ratio])
) as piv
The correct syntax for PIVOT is:
PIVOT
(
<aggregation function>(<column being aggregated>)
FOR
[<column that contains the values that will become column headers>]
IN ( [first pivoted column], [second pivoted column],
... [last pivoted column])
) AS <alias for the pivot table>
Hence, you have to place date values not [Tot_GPS_Cnt], [Tot_GND_Cnt], [Per_Ratio] in place of pivoted columns:
SELECT CallDate=col, [2015-04-24], [2015-04-25], [2015-04-26], [2015-04-27]
FROM
( select CallDate, col, value from #tbl_Res1
cross apply
(
SELECT 'Tot_GPS_Cnt',cast(Tot_GPS_Cnt as varchar(10)) UNION ALL
SELECT 'Tot_GND_Cnt', cast(Tot_GND_Cnt as varchar(10)) UNION ALL
SELECT 'Per_Ratio', cast(Per_Ratio as varchar(10))
) c (col,value)
) d
PIVOT
(
max(value) for CallDate in ([2015-04-24], [2015-04-25], [2015-04-26], [2015-04-27])
) as piv
