Using PIVOT query in ViewObject

I was wondering if it's possible to create a ViewObject based on a query with PIVOT. The query looks like
SELECT * FROM myTable
PIVOT ( SUM(myTable.VALUE) FOR TIME IN ('2010', '2011'));
And I get the following error:
ORA-00907: missing right parenthesis.
The query works in SQL Developer.
JDev 11.1.1.6.0

My working query in SQL Developer is
SELECT * FROM (
SELECT TIME, VALUE
FROM MYTABLE
WHERE CODE = :pCode
PIVOT (
SUM(VALUE) FOR TIME IN (2009)
with TIME as NUMBER.
But if I copy it in a ViewObject I get the right parenthesis error. The '^' points to the T of PIVOT, not sure the location is accurate. My goal is then to use that VO with getEstimatedRowCount, executeQuery and also apply some ViewCriteria on it. I never worked with PIVOT query, so I am not sure if it makes a difference on what I can do with the VO.

How to pivot using pivot clause of sqlserver 2005 for three values

Dear all
            Is it possible to formulate the query using pivote clause of sqlserver 2005.
( Table name is) BridgeHawra
ReportDate,                 , Pole, DiameterCost,Flag,OuterDiaCost
01 jan 2014,               ,1     ,   4.5      ,yes,6
01 jan 2014,               ,2     ,   4.5        ,no,6
01 jan 2014,               ,3    , 5.5         ,no,6
02 jan 2014,               ,4     , 5.5        ,no,5.9
02 jan 2014,               ,5     , 5.5        ,no,6
1)Pole Col will have unique value.
o2)One pole will have one DiameterCost, but n number of DiameterCost can be there.
I have to show a report which should show , count of poles and cost(DiameterCost* pole count of the day of each DiameterCost) for each date and DiameterCost.
as following
DateOfReport            , PoleCountofDiameterCost4.5, DiameterCost4.5, PoleCountOfDiameterCost5.5,DiameterCost5.5
01 jan 2014             , 2
      ,(2*4.5)                        ,1
,(1*5.5)
02 jan 2014             , 0/null                                      ,0/null
                          ,2
,(2*5.5)
yours sincerely

Yes it is possible though you need to use dynamic pivot technique. Dynamic pivot allow you to select/display column names dynamically.
Below example does not use dynamic pivot,
--create table #temp(ReportDate datetime,Pole int, DiameterCost decimal(5,2),Flag varchar(3),OuterDiaCost decimal(5,2))
--insert into #temp values('01 jan 2014',1,4.5,'yes',6)
--insert into #temp values('01 jan 2014',2,4.5,'no',6)
--insert into #temp values('01 jan 2014',3,5.5,'no',6)
--insert into #temp values('02 jan 2014',4,5.5,'no',5.9)
--insert into #temp values('02 jan 2014',5,5.5,'no',6)
;with cte as (
select ReportDate,
DiameterCost * PoleCount as DiameterCost,
PoleCount ,
'PoleCountofDiameterCost'+cast(DiameterCost as varchar) column1,
'DiameterCost'+cast(DiameterCost as varchar) column2
from (
select ReportDate,DiameterCost,Count(Pole) as PoleCount from #temp
group by ReportDate,DiameterCost
) x
),cte1 as (
select * from cte
pivot( max(PoleCount) for column1 in ([PoleCountofDiameterCost4.50],[PoleCountofDiameterCost5.50])
) pvt
pivot( max(DiameterCost) for column2 in ([DiameterCost4.50],[DiameterCost5.50])
) pvt1
select ReportDate,
Max([PoleCountofDiameterCost4.50]) [PoleCountofDiameterCost4.50],
Max([DiameterCost4.50]) [DiameterCost4.50],
Max([PoleCountofDiameterCost5.50]) [PoleCountofDiameterCost5.50],
Max([DiameterCost5.50]) [DiameterCost5.50] from cte1
group by ReportDate

Getting counts and divide by sum in a single Pivot query

Hi,
I have a pivot query which gives the counts of all codes. I also have to divide the count with the total in the same query.
e.g
col1          col2                   col3
error_1       05-Jun-2012       parts
error_1      05_june_2012     parts
error_1      04_june_2012     consumables
error_2      04_june_2012     consumables
error_3      03_june_2012     parts
.Now the output should have the counts/divided by sum multiplied by 100. Basically, the percentage.
output will be something like
error                     June-2012                                 May-2012                              Feb-2012 ....      headers
error_1                    60%                                          0 %                                         0%
error_2                    20%                                          0                                             0%
error_3                    20%                                           0%                                         0%Any suggestions please?

Hi,
In 11g you can use pivot.
[http://www.oracle.com/technology/pub/articles/oracle-database-11g-top-features/11g-pivot.html]
example
SQL> desc customers
Name                                      Null?    Type
CUST_ID                                            NUMBER(10)
CUST_NAME                                          VARCHAR2(20)
STATE_CODE                                         VARCHAR2(2)
TIMES_PURCHASED                                    NUMBER(3)
When this table is selected:
select cust_id, state_code, times_purchased
from customers
order by cust_id;
The output is:
CUST_ID STATE_CODE TIMES_PURCHASED
      1 CT                       1
      2 NY                      10
      3 NJ                       2
      4 NY                       4
... and so on ...
Note how the data is represented as rows of values: For each customer, the record shows the customer's home state and how many times the customer purchased something from the store. As the customer purchases more items from the store, the column times_purchased is updated.
Now consider a case where you want to have a report of the purchase frequency each state�that is, how many customers bought something only once, twice, thrice and so on, from each state. In regular SQL, you can issue the following statement:
select state_code, times_purchased, count(1) cnt
from customers
group by state_code, times_purchased;
Here is the output:
ST TIMES_PURCHASED        CNT
CT               0         90
CT               1        165
CT               2        179
CT               3        173
CT               4        173
CT               5        152
... and so on ...
This is the information you want but it's a little hard to read. A better way to represent the same data may be through the use of crosstab reports, in which you can organized the data vertically and states horizontally, just like a spreadsheet:
Times_purchased
             CT           NY         NJ      ... and so on ...
1             0            1          0      ...
2            23          119         37      ...
3            17           45          1      ...
... and so on ...
Prior to Oracle Database 11g, you would do that via some sort of a decode function for each value and write each distinct value as a separate column. The technique is quite nonintuitive however.
Fortunately, you now have a great new feature called PIVOT for presenting any query in the crosstab format using a new operator, appropriately named pivot. Here is how you write the query:
select * from (
   select times_purchased, state_code
   from customers t
pivot
   count(state_code)
   for state_code in ('NY','CT','NJ','FL','MO')
order by times_purchased
Here is the output:
. TIMES_PURCHASED       'NY'       'CT'       'NJ'       'FL'       'MO'
              0      16601         90          0          0          0
              1      33048        165          0          0          0
              2      33151        179          0          0          0
              3      32978        173          0          0          0
              4      33109        173          0          1          0
... and so on ...

Dynamic SQL and Pivot Query in 11G

Hello all,
I am using APEX and 11G I am trying to create a report based on the results of a pivot query. Below is the code to build the query string. The :P4_EPSB_PERIOD_HOLD holds data like (SEP-08') for example.
declare
q varchar2(4000);
begin
q:=q ||' select * FROM';
q:=q ||' ( ';
q:=q ||' select segment2, ';
q:=q ||' accounted_dr, ';
q:=q ||' period_name ';
q:=q ||' from gl_je_lines a, ';
q:=q ||' gl_code_combinations b';
q:=q ||' where b.code_combination_id = a.code_combination_id';
q:=q ||' and segment2 >= :P4_EPSB_OBJECT_FROM';
q:=q ||' and segment2 <= :P4_EPSB_OBJECT_TO';
q:=q ||' and period_name IN :P4_EPSB_PERIOD_HOLD';
q:=q ||' and segment4 >= :P4_EPSB_LOCATION_FROM';
q:=q ||' and segment4 <= :P4_EPSB_LOCATION_TO';
q:=q ||' )';
q:=q ||' PIVOT';
q:=q ||' (';
q:=q ||' sum(accounted_dr)';
q:=q ||' for period_name IN :P4_EPSB_PERIOD_HOLD';
q:=q ||' )';
return q;
end;
I get the missingfailed to parse SQL query:
ORA-00906: missing left parenthesis
If I print the sql statement that the query generates, I get the following code, which, if the varaibles are hard-coded, works fine.
select * FROM ( select segment2, accounted_dr, period_name from gl_je_lines a, gl_code_combinations b where b.code_combination_id = a.code_combination_id and segment2 >= :P4_EPSB_OBJECT_FROM and segment2 <= :P4_EPSB_OBJECT_TO and period_name IN :P4_EPSB_PERIOD_HOLD and segment4 >= :P4_EPSB_LOCATION_FROM and segment4 <= :P4_EPSB_LOCATION_TO ) PIVOT ( sum(accounted_dr) for period_name IN :P4_EPSB_PERIOD_HOLD )
Any advice as to how to tackle this would be most welecome and appreciated.
Thanks

P4_EPSB_PERIOD_HOLDcome with single quotes? like 'SEP-08' or SEP-08

11G Pivot Query with Oracle EBS

Hello all,
We are trying to use the 11G pivot query function with data from Oracle E-Business Suite. We have an 11G database installed with our Oracle APEX. We cannot seem to get the pivot function to work. At a glance, would anyone be able to see any glaring errors in our syntax. I am not certain it is possible to provide test data so...
We are trying to have column headings with the Period Names SEP-08 OCT-08 NOV-08, with rows of segment2 007751 and accounted_dr as the dataset.
When we run the sql we get an error ORA-00904: "PERIOD_NAME": invalid identifier.
Any help or insight would be greatly appreciated.

group by segment2, period_nameDon't use GROUP BY. When you use PIVOT, the grouping is implied by what is in the PIVOT clause and what is not.
Try this:
select    *
from        (
       select segment2
       ,       accounted_dr
       ,       period_name

       and       segment2 = '007751'
pivot       (
       sum (accounted_dr)
       for period_name in ('SEP-08','OCT-08','NOV-08')
;which is just your posted query without the GROUP BY clause.

I have about 5 million rows in StageTable and the pivot query returns 32,000 rows. It takes about 3 and a half minutes to run this query, whether I am outputting the results to the results window in SSMS or selecting into a new table.
I checked the execution plan for this query (outputting to results window) and the only operation that takes any time is the non-clustered index scan (84% with Stream aggregate showing 14%).
Here are the things I compared this to. I ran a select from this table using just the columns in the index. The results returned in less than one minute and as expected the most expensive operation (100%) was the non-clustered index scan.
By the way, a select into returned almost immediately.
If I take the pivot results (after a select into) and create a new table by select into, it takes almost no time for the query to finish.
I did an estimated execution plan on these three queries (where PivotTable is a dump of the pivot query into a heap):
WITH cte as (
SELECT
DateKey ,
VersionNumber ,
SetID ,
ClassID ,
VariableName ,
PeriodNumber ,
PeriodData
from StagingTable
SELECT
DateKey ,
VersionNumber ,
SetID ,
ClassID ,
VariableName,
[0], [1], [2], [3], ,,,, [360]
from cte
pivot (SUM(PeriodData)
FOR PeriodNumber IN (
[0], [1], [2], [3], ..., [360]
) as pvt;
SELECT * from PivotTable;
SELECT
DateKey ,
VersionNumber ,
SetID ,
ClassID ,
VariableName ,
PeriodNumber ,
PeriodData
from StagingTable;
The first query (pivot query) had a cost of 41%, the second 25% (select pivottable) and the third 34% (select base table). These are nowhere close to the ratios of the amount of time that it takes to run these queries (pivot query 3.5 minutes,
select PivotTable 5 seconds and select base table almost one minute).
For the following:
WITH cte as (
SELECT
DateKey ,
VersionNumber ,
SetID ,
ClassID ,
VariableName ,
PeriodNumber ,
PeriodData
from StagingTable
SELECT
DateKey ,
VersionNumber ,
SetID ,
ClassID ,
VariableName,
[0], [1], [2], [3], ,,,, [360]
into newTable1
from cte
pivot (SUM(PeriodData)
FOR PeriodNumber IN (
[0], [1], [2], [3], ..., [360]
) as pvt;
SELECT *
into newTable2
from PivotTable;
SELECT
DateKey ,
VersionNumber ,
SetID ,
ClassID ,
VariableName ,
PeriodNumber ,
PeriodData
into newTable3
from StagingTable;
The distribution of query cost is strikingly different. The pivot query has a cost of 98% and the other two queries have costs of 1%. The big difference between these queries and the versions that just output the results (in the execution plan)
is in the table insert. The pivot query shows a cost of 26,000 while the select from pivottable shows cost of 160 and select from StagingTable shows cost of 280.
What else can I look at? Also, what else can I try to optimize the pivot query.
For now, I am going to see if I get better performance letting SSRS do the pivoting.

I have finally nailed down what is causing the bottleneck.
The Compute Scalar step for some reason shows almost no cost to the execution plan. But I noticed that the actual number of rows is 5 million (the same as the scan). It appears that SQL Server expands every row to 360+ columns, all 5 million
of them.
So I did an experiment. I took the table that I was populating and did a cross join to a number table. This table has 30 K rows and 360 columns. I figured that if I select 150 rows from the number table it will generate around 5 million
rows. The results were almost identical to using the MAX(CASE WHEN ...) construct: 1 minute and some change.
I then cross joined with only 75 rows. It took 30 seconds. 37 rows took about 15 seconds.
So the Compute Scalar costs a lot more then the Execution plan analyzer says.
SSIS appears to gather one row at a time. Once it finishes one row, one group by set, it sends the row on its way. So, in my case, the 5 million rows is read in with 7 columns and 30 K rows are output with 365 columns or so.
SQL Server creates 5 million rows with 365 columns, then aggregates them down to 30 K rows.
Thank you, Tom for you discussion with me on this. I think that I can present my thoughts to my lead.

Power Pivot Bug: Can't Save Edits to Power Pivot Query without checking Teradata Connection's "Save my password" Option

Can't edit and re-Save Power Pivot query with Teradata connection (using LDAP security mechanism) unless "Save my password" option was checked. Without this option I receive this error upon attempt to Save changes made to the query ...
The following exception occurred while the managed IDbConnection interface was being used: [TeraGSS Security Library] [115022] Exception occurred in TERAGSS layer. See inner exception for details.;TdgssAuthenticationTokenExchange delegate threw an exception.

Sorry you're right, the Office category isn't currently accepting bug reports in which case Olaf's suggestion to use the smiley face is the way to go. In Excel please go to File > Options > Trust Centre > 'Trust Centre Settings...' and check
that the Feeeback Tool is enabled.
If the option is greyed out like this...
... then you should be able to enable it by changing the value of the 'Enabled' registry key from a 0 to a 1 which you will find under: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Feedback. You will then need to close all Office applications
and re-launch Excel 2013.
Once the Feeback Tool has been enabled, you should see the smile face(s) in the top right hand corner of the Excel window and be able to send your feedback.

Using Power Query to import image files for Power View

I am trying to use Power Query to import image data from a SQL Azure database for use in Power View. I've selected both the source image table and the ?images table in the workbook query. The files seem to load as binary data in the Power
Query editor but when loaded to the data model with Power Pivot, the field becomes "text" type rather than binary. Does anyone know the procedure to use PowerQuery to load image files into PowerPivot?

Hi,
We currently do not support loading binary data from Power Query into the Power Pivot data model. This is something we'd like to address soon. For now, you will need to use the Power Pivot import capabilities if you want to achieve this.
Sorry about the inconvenience - we will try to enable this feature over the coming months.

Setting Column Names in Dynamic Pivot Query

Hi all,
I'm having trouble setting column names in a dynamic pivot query and was wondering if someone could please help me figure out what I need to do.
To help you help me, I've setup an example scenario in my hosted account. Here's the login info for my hosted site at [http://apex.oracle.com]
Workspace: MYHOSTACCT
Username : DEVUSER1
Password : MYDEVACCTAnd, here is my test application info:
ID     : 42804
Name   : dynamic query test
Page   : 1
Table 1: PROJECT_LIST         (Alias = PL... Listing of Projects)
Table 2: FISCAL_YEAR          (Alias = FY... Lookup table for Fiscal Years)
Table 3: PROJECT_FY           (Alias = PF... Intersection table containing project fiscal years)
Table 4: PROJECT_FY_HEADCOUNT (Alias = PFH... Intersection table containing headcount per project and fiscal year)Please forgive the excessive normalization for this example, as I wanted to keep the table structure similar to my real application, which has much more going on.
In my sample, I have the "Select Criteria" region, where the user specifies the project and fiscal year range that he or she would like to report. Click the Search button, and the report returns the project headcount in a pivoted fashion for the fiscal year range specified.
I've got it working using a hard-coded query, which is displayed in the "Hardcoded Query" region. In this query, I basically return all years, and set conditions on each column which determines whether that column should be displayed or not based on the range selected by the user. While this works, it is not ideal, as there could be many more fiscal years to account for, and this is not very dynamic at all. Anytime a fiscal year is added to the FISCAL_YEAR table, I'd have to update this page.
So, after reading all of the OTN SQL pivot forums and "Ask Tom" pivot thread, I've been able to create a second region labeled "Dynamic Query" in which I've created a dynamic query to return the same results. This is a much more savvy solution and works great; however, the column names are generic in the report.
I had to set the query to parse at runtime since the column selection list is dynamic, which violates SQL rules. Can anyone please help me figure out how I can specify my column names in the dynamic query region to get the same column values I'm getting in the hardcoded region?
Please let me know if you need anymore information, and many thanks in advance!
Mark

Hi Tony,
Thanks so much for your response. I've had to study up on the dbms_sql package to understand your function... first time I've used it. I've fed my dynamic query to your function and see that it returns a colon delimited list of the column names; however, I think I need a little more schooling on how and where exactly to apply the function to actually set the column names in APEX.
From my test app, here is the code for my dynamic query. I've got it in a "PL/SQL function body returning sql query" region:
DECLARE
v_query      VARCHAR2(4000);
v_as         VARCHAR2(4);
v_range_from NUMBER;
v_range_to   NUMBER;
BEGIN
v_range_from := :P1_FY_FROM;
v_range_to   := :P1_FY_TO;
v_query      := 'SELECT ';
-- build the dynamic column selections by looping through the fiscal year range.
-- v_as is meant to specify the column name as (FY10, FY11, etc.), but it's not working.
FOR i IN v_range_from.. v_range_to LOOP
    v_as    := 'FY' || SUBSTR(i, 3, 4);
    v_query := v_query || 'MAX(DECODE(FY_NB,' || i || ',PFH_HEADCOUNT,0)) '
      || v_as || ',';
END LOOP;
-- add the rest of the query to the dynamic column selection
v_query := rtrim(v_query,',') || ' FROM ('
    || 'SELECT FY_NB, PFH_HEADCOUNT FROM ('
    || 'SELECT FY_ID, FY_NB FROM FISCAL_YEAR) A '
    || 'LEFT OUTER JOIN ('
    || 'SELECT FY_ID, PFH_HEADCOUNT '
    || 'FROM PROJECT_FY_HEADCOUNT '
    || 'JOIN PROJECT_FY USING (PF_ID) '
    || 'WHERE PL_ID = ' || :P1_PROJECT || ') B '
    || 'ON A.FY_ID = B.FY_ID)';
RETURN v_query;
END;I need to invoke GET_QUERY_COLS(v_query) somewhere to get the column names, but I'm not sure where I need to call it and how to actually set the column names after getting the returned colon-delimited list.
Can you (or anyone else) please help me get a little further? Once again, feel free to login to my host account to see it first hand.
Thanks again!

APEX 3.2 -ORACLE 10G - PIVOT QUERY

Hello, i searched around the forum and i cound't find an answer to this specific matter, although i saw some replies that were close...
i need to creat a form based on a pivot query. but oracle 10g doesn't support that feature so i hope someone can help me.
my problem is that the number of columns will be variable. here's an example:
ORIGINAL TABLE
NAME     KMS     VEHICLE
Joe     100     AUDI
Tom     300     VW
Mark     150     FORD
Ann     250     FORD
Joe     200     VW
Tom     123     AUDI
Mark     345     AUDI
Ann     45     VW
Joe     6     FORD
Tom     67     FORD
Mark     46     VW
Ann     99     AUDI
DESIRED RESULT
Joe     Tom     Mark     Ann     Vehicle
100     123     345     99     AUDI
6     67     150     250     FORD
200     300     46     45     VW
the new columns will be the values in the old NAME column. BUT these values are variable. today its joe,tom,mark and ann tomorrow it could be silvia, tony,richard,harry , william and jane. this means the usuall replies i saw, using MAX and DECODE will not apply because i never know what values or how many values are in this column. with pivot i can get this done.... how can i do this in oracle 10g? is there a way to creat a ser function Pivot somehow? ideas?
thanks!

Oracle 11 Pivot Query

Hi,
I have 2 questions on the pivot query below:
1 - I want to have total by Country and Year
2 - I want to allow the use a dynamic year range (like year between 1990 and 2000)
Thanks,
Ribhi
select * from (
select CNTRY_NAME, MYYEAR,AM_AMOUNT
from yearly_lending t
pivot
sum(AM_AMOUNT)
for MYYEAR in (1974,1975,1976,1977,1978,1979,1980,1981,1982,1983,1984,1985,1986,1987,1988,1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009)
order by CNTRY_NAME

Hi all,
Thank you for your help.
The qury working as expected, but i wont to add total by country and year
Country 1974 1975 1976 1977 1977 1978...2009 Total
Jordan 10 5 0 3 5 1 24
Egypt 5 0 0 0 10 0 15
Syria 8 2 10 20
Total 23 7 0 3 15 11 59
also would like to select year range rather than entering year by year example year from 2000 to year 2009
I created a view from the qury below and then my pivot query
select
rtrim(cntry.short_name_e) cntry_name,
to_char(e.date0,'yyyy') myYear,
am.value / 1000000 am_amount,
a.fk_countrycode a_cntry
from event e,
agreement_amount am,
agreement a, in_country cntry
where
a.number0 = e.fk_agreementnumber
AND A.SUB_NUMBER <>'P'
AND a.fk_countrycode = cntry.intl_code
and a.sub_number = e.fk_agreementsub_nu
and a.type = e.fk_agreementtype
/*and rtrim(a.status) <> 'CANCELLED' */
and rtrim(e.type) = 'SIGNING'
and rtrim(e.fk_agreementtype) <> 'GRANT'
and e.fk_agreementnumber = am.fk_agreementnumber
and e.fk_agreementsub_nu = am.fk_agreementsub_nu
and e.fk_agreementtype = am.fk_agreementtype
and am.serial_number = 1
order by rtrim(cntry.short_name_e) ,to_char(e.date0,'yyyy')
Best regards,
Ribhi
