I was able to display every row in column using pivot however when there are multiple values, it displays only one of the row values. My suspicion lies on the MAX function in the for loop, however, have not been able to find a successful replacement.
I've tried other SQL functions.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT #cols = STUFF((SELECT ',' + QUOTENAME(Provincia)
FROM Codigos_Postales
GROUP BY Provincia
ORDER BY Provincia
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SET #query = N'SELECT Poblacion,' + #cols + N' from
(
select * from Codigos_Postales
) x
pivot
(
MAX(Codigo_Postal)
for Provincia in (' + #cols + N')
) p ORDER BY Poblacion ASC'
EXEC sp_executesql #query;
Table I'm trying to pivot:
Result:
Expected Result:
If I understand corerctly, adding ROW_NUMBER to your source data will do the trick. The sample PIVOT script will be as below. Just ignore the RN column from your final output, that's it.
SET #query =
N'SELECT Poblacion,' + #cols + N' from
(
SELECT
ROW_NUMBER() OVER (ORDER BY Provincia) RN,
*
FROM Codigos_Postales
) x
PIVOT
(
MAX(Codigo_Postal)
FOR Provincia IN (' + #cols + N')
) p ORDER BY Poblacion ASC'

I want to declare a table variable and fill it from the pivot with dynamic column to perform join statement.
DECLARE #cols AS NVARCHAR(MAX), #query AS NVARCHAR(MAX)
SELECT #cols =
STUFF((SELECT DISTINCT ',' + QUOTENAME(ColName)
FROM [sbs].[ProposalAmounts]
GROUP BY ColName, ProposalID
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')
SET #query = N'SELECT ProposalID, ' + #cols + N' from
(select ProposalID, Amount, ColName from [sbs].[ProposalAmounts]) x
PIVOT
(MAX(Amount)for ColName in (' + #cols + N')) p '
EXEC sp_executesql #query;
This is what I've done so far and I'm confused as to how to declare a table variable that has dynamic columns in it.
This is the result of the query above:
And this is the result of the table I want to perform join statement:
Like Jeroen Mostert commented, you need to make everything dynamic.
I would suggest to put the join inside the dynamic query. Instead of a table variable, I use a common table expression.
DECLARE #cols AS NVARCHAR(MAX), #query AS NVARCHAR(MAX);
SELECT #cols =
STUFF((SELECT DISTINCT N', ' + QUOTENAME([ColName])
FROM [_tmp_].[ProposalAmounts]
GROUP BY [ColName], [ProposalID]
FOR XML PATH(N''), TYPE).value(N'.', N'NVARCHAR(MAX)'), 1, 2, N'')
SET #query = N'
WITH [CTE_Pivoted_ProposalAmounts] AS
(
SELECT [ProposalID], ' + #cols + N'
FROM
(SELECT [ProposalID], [Amount], [ColName] FROM [sbs].[ProposalAmounts]) x
PIVOT (MAX([Amount]) FOR [ColName] IN (' + #cols + N')) p
)
SELECT *
FROM
[sbs].[OtherTable] ot
INNER JOIN [CTE_Pivoted_ProposalAmounts] ppa ON ppa.[ProposalID] = ot.[ProposalID];
';
EXEC sp_executesql #query;
You need to replace [sbs].[OtherTable] with the actual name of the table you want to join with. And you might also tweak the join criteria and the fields in the SELECT clause. This code here is just a simple example. I assume you will manage to fix the query yourself to make it behave as you expect.
I'm trying to Pivot a Table on X and Y position. The table is in a format similar to below.
Each row has a value which is relative to its Row and Column Position.'AThing' and 'FileName' are to be ignored in the data set.
So if this was pivoted we would get:
Iv'e been trying for a while but can't seem to figure it out, any ideas?
EDIT: Number of Fields are dynamic per 'FileName'. I have managed to extract the column names but not the data using:
-- Construct List of Columns to Pivot
SELECT #PivotCols =
STUFF(
(SELECT ',' + QUOTENAME(FieldName)
FROM #Data
GROUP BY ColPos, FieldName

FROM #Data
GROUP BY ColPos, FieldName
) x
PIVOT
(
MIN(ColPos)
FOR FieldName IN (' + #PivotCols + N')
) p'
EXEC sp_executesql #PivotQuery
Please try this code:
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(FieldName)
FROM (SELECT distinct p.FieldName FROM Tablename AS p
) AS x;

SELECT ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT p.Value, p.FieldName, p.RowPos
FROM Tablename AS p
) AS j
PIVOT
(
MAX(Value) FOR FieldName IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;

I am trying to cross join two pivot tables.
--First Pivot table query gets columns of drug_names and produces the row value
--of the drug_id.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
Select #cols = STUFF((SELECT ',' + QUOTENAME(drug)
from _app_drugs
group by drug, drug_id,order_number
order by order_number
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = N'SELECT ' + #cols + N' from
(
select drug_id, drug
from _app_drugs
) x
pivot
(
max(drug_id)
for drug in (' + #cols + N')
) p'
exec sp_executesql #query;
--The second pivot table simply gets the signature_labels and displays the label name in the column and displays the label_id as the row value.
DECLARE #cols AS NVARCHAR(MAX),#scols as NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
Select #cols = STUFF((SELECT ',' + QUOTENAME(signature_label)
from _app_signature_labels
WHERE _app_signature_labels.isactive=1
group by signature_label_id, signature_label,ordernumber
order by ordernumber
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = N'SELECT ' + #cols + N' from
(
select signature_label_id,signature_label
from _app_signature_labels
) x
pivot
(
max(signature_label_id)
for signature_label in (' + #cols + N')
) p'
exec sp_executesql #query;
Now I just need to know how to combine these two pivot tables as one table... they don't have a common field and don't need one.
Can anybody help me with this one?
Thank you
You can execute two separate dynamic SQL statements into two global temp tables and then combine the result, like this:
IF object_id('tempdb..##tmpResult1') IS NOT NULL
BEGIN
DROP TABLE ##tmpResult1
END
IF object_id('tempdb..##tmpResult2') IS NOT NULL
BEGIN
DROP TABLE ##tmpResult2
END
DECLARE #cols AS NVARCHAR(MAX),
#cols2 AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#query2 AS NVARCHAR(MAX)
Select #cols = STUFF((SELECT ',' + QUOTENAME(drug)
from _app_drugs
group by drug, drug_id,order_number
order by order_number
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = N'SELECT ' + #cols + N' INTO ##tmpResult1 from
(
select drug_id, drug
from _app_drugs
) x
pivot
(
max(drug_id)
for drug in (' + #cols + N')
) p'
exec sp_executesql #query;
--The second pivot table simply gets the signature_labels and displays the label name in the column and displays the label_id as the row value.
Select #cols2 = STUFF((SELECT ',' + QUOTENAME(signature_label)
from _app_signature_labels
WHERE _app_signature_labels.isactive=1
group by signature_label_id, signature_label,ordernumber
order by ordernumber
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query2 = N'SELECT ' + #cols2 + N' INTO ##tmpResult2 from
(
select signature_label_id,signature_label
from _app_signature_labels
) x
pivot
(
max(signature_label_id)
for signature_label in (' + #cols2 + N')
) p'
exec sp_executesql #query2;
SELECT * FROM ##tmpResult1 t1
INNER JOIN ##tmpResult2 t2 ON t1.ordernumber = t2.ordernumber
This is also a way to address this error when doing a large PIVOT query: Internal error: An expression services limit has been reached. Please look for potentially complex expressions in your query, and try to simplify them.
I am trying to pivot table DYNAMICALLY but couldn't get the desired result.
Here is the code to create a table
create table Report
(
deck char(3),
Jib_in float,
rev int,
rev_insight int,
jib_out float,
creation int
)
insert into Report values
('A_1',0.345,0,0,1.23,20140212),
('B_2',0.456,0,4,2.34,20140215),
('C_3',0.554,0,6,0.45,20140217),
('D_4',0.231,0,8,7.98,20140222),
('E_5',0.453,0,0,5.67,20140219),
('F_6',0.344,0,3,7.23,20140223)'
Code written so far.... this pivots the column deck and jib_in into rows but thats it only TWO ROWS i.e the one i put inside aggregate function under PIVOT function and one i put inside QUOTENAME()
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(deck)
FROM (SELECT p.deck FROM dbo.report AS p
GROUP BY p.deck) AS x;
SET #sql = N'
SELECT ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT p.deck, p.jib_in
FROM dbo.report AS p
) AS j
PIVOT
(
SUM(jib_in) FOR deck IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;
EXEC sp_executesql #sql;
I need all the columns to be pivoted and show on the pivoted table. any help would be appreciated. I am very new at dynamic pivot. I tried so many ways to add other columns but no avail!!
I know there are other ways please feel free to mention if there is any other way to get this right.
Please use this (If you are getting Collation issue, please change all the 3 INT datatypes):
STATIC code:
SELECT HEADER, [A_1],[B_2],[C_3],[D_4],[E_5],[F_6]
FROM
(SELECT DECK,HEADER, VALUE FROM REPORT
UNPIVOT
(
VALUE FOR HEADER IN ([JIB_IN],[REV],[REV_INSIGHT],[JIB_OUT],[CREATION])
) UNPIV
) SRC
PIVOT
(
SUM(VALUE)
FOR DECK IN ([A_1],[B_2],[C_3],[D_4],[E_5],[F_6])
) PIV
Using Dynamic SQL:
DECLARE #COLSUNPIVOT AS NVARCHAR(MAX),
#QUERY AS NVARCHAR(MAX),
#COLSPIVOT AS NVARCHAR(MAX)
SELECT #COLSUNPIVOT = STUFF((SELECT ','+QUOTENAME(C.NAME)
FROM SYS.COLUMNS AS C
WHERE C.OBJECT_ID = OBJECT_ID('REPORT') AND C.NAME <> 'DECK'
FOR XML PATH('')), 1, 1, '')
SELECT #COLSPIVOT = STUFF((SELECT ',' + QUOTENAME(DECK)
FROM REPORT T FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')
SET #QUERY
= 'SELECT HEADER, '+#COLSPIVOT+'
FROM
(
SELECT DECK,HEADER,VALUE FROM REPORT
UNPIVOT
(
VALUE FOR HEADER IN ('+#COLSUNPIVOT+')
) UNPIV
) SRC
PIVOT
(
SUM(VALUE)
FOR DECK IN ('+#COLSPIVOT+')
) PIV'
EXEC(#QUERY)
select *
from (
select vtid, convert(date, dtime) as Date from Transaction_tbl where locid = 5
) as vt
pivot (
count(vtid)
for vtid in (select vtid from VType_tbl)
) as pvt
while executing this query am getting error
Incorrect syntax near the keyword 'select'." and Incorrect syntax near
')'.
actually I have one more table,name= Vtype_table , How Can I load all vtid from vtype table in this query? I want to get output depend upon vtid.
Any help greatly appreciated.
Your PIVOT syntax is correct except you are using a SELECT statement inside your PIVOT.
You cannot use a SELECT statement inside the PIVOT IN clause to select column headers. It is required that the columns for the IN clause be known prior to executing the query.
If you are looking to generate a dynamic list of vtid values, then you will need to use dynamic SQL to get the result and the syntax will be similar to the following:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(vtid)
from VType_tbl
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Date, ' + #cols + '
from
(
select vtid, convert(date, dtime) as Date
from Transaction_tbl
where locid = 5
) d
pivot
(
count(vtid)
for vtid in (' + #cols + ')
) p '
execute(#query);
Edit, if you want the type names to appear then you should be able to use the following:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(vt_name)
from VType_tbl
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Date, ' + #cols + '
from
(
select v.vt_name, convert(date, dtime) as Date
from Transaction_tbl t
inner join VType_tbl v
on t.vtid = v.vtid
where locid = 5
) d
pivot
(
count(vt_name)
for vt_name in (' + #cols + ')
) p '
execute(#query)
Note: I am guessing on the column name for VType_tbl
