Query Schema error adding columns for a query at workbench channel

Hello experts,
For our customer, we have created a custom query and it has been included into the query group Master Agreement List to be also used on the Master Agreement List Channel. However, when use tries to add columns, following error is raised:
Do you know if this issue can be fixed? Is there any system property controlling this property?
Thanks in advance and best regards,
Isaac

Hello Isaac,
Thank you for providing the additional details. Some of the saved changes to the advanced list page query is stored as XML data in the database, so as rightly pointed out by Bogdan it appears that you may have hit the limit especially when dealing with large number of columns. Since the limitation is
at the DB level our options for a solution will be limited as well. I’m following up with development team to see if there is a way to optimize the xml to make little bit more room or may be come up with an alternate approach. Either way it would require product code change. It would be helpful if you could open a message and add the details so we can track it.
Regards,
Vikram

Hi ,
Pallet_ID parameter seems to passing string like 'SGAC2207H0' . Check and change the parameter to pass numbers by checking the assignment to the value column in the parameter. If still need the string to be passed , Try the below expression
="select pallet_id, pallet_create_dm,pn_id from MATS_ITG.pwax_pen_link where pallet_id in ('"& Join(Parameters!pallet_id.Value,"','") &"')"

Adding columns to content query

I have created a Content Query that retrieves all of my tasks from my site collection that meets my filter criteria. However, The Item Views are incredibly limited
(basically just the title). I want to add ~5-7 additional columns to the query, such as due date. I understand I may have to do this through SharePoint designer. Please advise and if coding is required, please let me know what code to use.

Hi,
I understand that you want to add columns to content query web part.
To include additional columns in the Web Part's query, we need to perform some minor customization in the .webpart file. We should programmatically instruct the Web Part to rename columns to names the default XSLT transformation expects, and then render
the columns by using the default XSLT transformation styles. For more information:
http://msdn.microsoft.com/en-us/library/ms497457(v=office.14).aspx
But the default XSLT transformations can render the following four fields:
Title, Description, LinkUrl, and ImageUrl, we can add a column and display it as the
Description field in the Web Part. If we want the other columns to appear in addition to the KB title and product, modify the XSLT transformation and add the rendering for the additional columns.

I am using oracle 10i

Cfreport ("HTML format") missing columns for a query

Using Linux Fedora, ColdFusion 8 Developer Edition.
Problem:
The command:
<cfreport
format="HTML"
template="ReportTemplateHtml.cfr"
filename="Report.html"
overwrite="yes"
query=#structReport.query#
>
With Format equal to PDF or RTF, which is correct output:
"item" "Description" "Qty" "Unit Price" "Extension"
The HTML output writes the following columns:
"item" "" "" "Unit Price" "Extension"
The "Description" and "Qty" are missing.
Any ideas as to why data is missing from HTML report?
The html output for the table is as follows:

Query Builder is a crutch tool. Small, lightweight, but limited. It does not have every inline function you see in the SQL reference guide. If you need more, then you have to do more on your own.

Adding column values in query designer

Hi,
I have requirement to add value in query designer the values should look like this
Column A     Column B
10                    10
20                    30
30                    60
40                    100
the first values of column B will be same as Column A 10. The second value of column B = column A 1st value +Column A second value similarly Third value of column B = 1st + 2nd + 3rd values of column a. So on and so forth
Any help will be highly appriciated.

Hi,
Welcome to the forum!
Do you want the data from TableC presented
(1) in one column, or
(2) in several columns (a different column of results for each row in the original TableC)?
(1) Is called String Aggregation and is easier than (2).
The best way to do this is with a user-defined aggregate function (STRAGG) which you can copy from asktom.
Ignoring TableA for now, you could get what you want by saying
SELECT    b.rtype
,         STRAGG (   c.compname
                 || ' '
                 || c.conc
                 ) AS c_data
FROM      TableB b
JOIN      TableC c ON b.id = c.b_id
GROUP BY b.rtype;(2) Presenting N rows of TableC as it they were N columns of the same row is called a pivot. Search for "pivot" or "rows to columns" to find examples of how to do this.
The number of columns in a result set is hard-coded into the query. If you don't know ahead of time how many rows in TableC will match a row in TableB, you can:
(a) guess high (for example, hard-code 20 columns and let the ones that never contain a match be NULL) or,
(b) use Dynamic SQL to write a query for you, which has exactly as many columns as you need.
The two scripts below contain basic information on pivots.
This first script is similar to what you would do for case (a):
--     How to Pivot a Result Set (Display Rows as Columns)
--     For Oracle 10, and earlier
--     Actually, this works in any version of Oracle, but the
--     "SELECT ... PIVOT" feature introduced in Oracle 11
--     is better. (See Query 2, below.)
--     This example uses the scott.emp table.
--     Given a query that produces three rows for every department,
--     how can we show the same data in a query that has one row
--     per department, and three separate columns?
--     For example, the query below counts the number of employess
--     in each departent that have one of three given jobs:
PROMPT     ========== 0. Simple COUNT ... GROUP BY ==========
SELECT     deptno
,     job
,     COUNT (*)     AS cnt
FROM     scott.emp
WHERE     job     IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY     deptno
,          job;
Output:
    DEPTNO JOB              CNT
        20 CLERK              2
        20 MANAGER            1
        30 CLERK              1
        30 MANAGER            1
        10 CLERK              1
        10 MANAGER            1
        20 ANALYST            2
PROMPT     ========== 1. Pivot ==========
SELECT     deptno
,     COUNT (CASE WHEN job = 'ANALYST' THEN 1 END)     AS analyst_cnt
,     COUNT (CASE WHEN job = 'CLERK'   THEN 1 END)     AS clerk_cnt
,     COUNT (CASE WHEN job = 'MANAGER' THEN 1 END)     AS manager_cnt
FROM     scott.emp
WHERE     job     IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY     deptno;
--     Output:
    DEPTNO ANALYST_CNT CLERK_CNT MANAGER_CNT
        30           0          1           1
        20           2          2           1
        10           0          1           1
--     Explanation
(1) Decide what you want the output to look like.
     (E.g. "I want a row for each department,
     and columns for deptno, analyst_cnt, clerk_cnt and manager_cnt)
(2) Get a result set where every row identifies which row
     and which column of the output will be affected.
     In the example above, deptno identifies the row, and
     job identifies the column.
     Both deptno and job happened to be in the original table.
     That is not always the case; sometimes you have to
     compute new columns based on the original data.
(3) Use aggregate functions and CASE (or DECODE) to produce
     the pivoted columns.
     The CASE statement will pick
     only the rows of raw data that belong in the column.
     If each cell in the output corresponds to (at most)
     one row of input, then you can use MIN or MAX as the
     aggregate function.
     If many rows of input can be reflected in a single cell
     of output, then use SUM, COUNT, AVG, STRAGG, or some other
     aggregate function.
     GROUP BY the column that identifies rows.
PROMPT     ========== 2. Oracle 11 PIVOT ==========
WITH     e     AS
(     -- Begin sub-query e to SELECT columns for PIVOT
     SELECT     deptno
     ,     job
     FROM     scott.emp
)     -- End sub-query e to SELECT columns for PIVOT
SELECT     *
FROM     e
PIVOT     (     COUNT (*)
          FOR     job     IN     ( 'ANALYST'     AS analyst
                         , 'CLERK'     AS clerk
                         , 'MANAGER'     AS manager
NOTES ON ORACLE 11 PIVOT:
(1) You must use a sub-query to select the raw columns.
An in-line view (not shown) is an example of a sub-query.
(2) GROUP BY is implied for all columns not in the PIVOT clause.
(3) Column aliases are optional.
If "AS analyst" is omitted above, the column will be called 'ANALYST' (single-quotes included).

The second script, below, shows one way of doing a dynamic pivot in SQL*Plus:
{code}
How to Pivot a Table with a Dynamic Number of Columns
This works in any version of Oracle
The "SELECT ... PIVOT" feature introduced in Oracle 11
is much better for producing XML output.
Say you want to make a cross-tab output of
the scott.emp table.
Each row will represent a department.
There will be a separate column for each job.
Each cell will contain the number of employees in
     a specific department having a specific job.
The exact same solution must work with any number
of departments and columns.
(Within reason: there's no guarantee this will work if you
want 2000 columns.)
Case 0 "Basic Pivot" shows how you might hard-code three
job types, which is exactly what you DON'T want to do.
Case 1 "Dynamic Pivot" shows how get the right results
dynamically, using SQL*Plus.
(This can be easily adapted to PL/SQL or other tools.)
PROMPT     ========== 0. Basic Pivot ==========
SELECT     deptno
,     COUNT (CASE WHEN job = 'ANALYST' THEN 1 END)     AS analyst_cnt
,     COUNT (CASE WHEN job = 'CLERK'   THEN 1 END)     AS clerk_cnt
,     COUNT (CASE WHEN job = 'MANAGER' THEN 1 END)     AS manager_cnt
FROM     scott.emp
WHERE     job     IN ('ANALYST', 'CLERK', 'MANAGER')
GROUP BY     deptno
ORDER BY     deptno

EXPLANATION:
The basic pivot assumes you know the number of distinct jobs,
and the name of each one. If you do, then writing a pivot query
is simply a matter of writing the correct number of ", COUNT ... AS ..."\
lines, with the name entered in two places on each one. That is easily
done by a preliminary query, which uses SPOOL to write a sub-script
(called dynamic_pivot_subscript.sql in this example).
The main script invokes this sub-script at the proper point.
In practice, .SQL scripts usually contain one or more complete
statements, but there's nothing that says they have to.
This one contains just a fragment from the middle of a SELECT statement.
Before creating the sub-script, turn off SQL*Plus features that are
designed to help humans read the output (such as headings and
feedback messages like "7 rows selected.", since we do not want these
to appear in the sub-script.
Turn these features on again before running the main query.
{code}

Count number of colums for that query.

Hi all,
I need to return the number of columns for that query, the columns are not known...dynamic columns.
i.e
1) Example 1
select column1, column2
from dual;
Result should return counter = 2
2) Example 2:
select column1, column2,column3,column4, column5
from dual;
Result should return counter = 5
from dual;
Result should return counter = 2
Thanks.

Authorization for ABAP Query

Hello all,
Can I benefit a little from your experience with SAP Query(ABAP) and Adhoc Query(ABAP)?
My customer want to use both SAP Query and Adhoc Query.
And they want to separate for SAP Query as preset report program and Adhoc Query as general-purpose reporting tool.
And I want to know how to separate authorizations of SAP Query and Adhoc Query as below.
As for SAP Query, users can only execute and cannnot change or delete it.
As for Adhoc Query, users can save Queries they created or changed in Adhoc Query.
I know there is only one authorization object for SAP Query:S_QUERY
Is there any solution for that kind of request?
Thanks and Regards,
Hanae

Hello,
We have check in the abap program ask you functional to give the authorization object i.e. y_k_autchk
and ask him for which filed we have to give authorizaion.
AUTHORITY-CHECK OBJECT y_k_autchk
ID 'WERKS' FIELD y_wa_tvarv-low.

Newly added column not displayed in Interactive report

Hello,
I have a tableA with 3 columns.In the application i am displaying as Form with Report region as Interactive report(Oracle 10g Application Express 3.2).
I added one column to tableA.Now when i am refreshing the report by adding that column in the select query,the new added column is not displayed in the application.
How can i do this so that the added column can be displayed.I dont want to delete the whole thing and redo it again.
Thanks
Siya

Hi Siya,
The Interactive Report will not show you the newly added columns by default. You have to select those columns from the actions menu and when all the required fields are displayed then save it as the default report.
Then you will be able to see all the columns.
Hope this solves your problem.
Thanks,
Satish.
