Using a parameter value as a column name

Hi,
   I have created an command like this:
update table1 set [Param.1] = '[Param.2]' where id = [Param.3]
where:
Param.1 = COL1
Param.2 = Hello
Param.3 = 1 (the primary key I want to change).
When I run this SQL Action I get the following error message:
java.sql.SQLException: ORA-01747: invalid user.table.column, table.column, or column specification
   I have double checked the values of my parameters and they are all correct. There is a column named COL1, and its type is varchar2, and there is PK = 1.
   So, my question is: Is it a limitation of xMII (we can not take column names from parameters) or there is a mistake here?
Thank you in advance,
Nuno Cunha

Hi Nuno,
I see you are trying to perform Dynamic SQL execution in Oracle.
In order to execute a Dynamic SQL you need to use the following syntax
EXECUTE IMMEDIATE 'Sql Statement with any runtime params like cloumns, even table names too';
And I guess you can use an Dynamic Sql only within a PL/SQL block.
Please refer to the below link for more details
[Dynamic SQL|http://download.oracle.com/docs/cd/B10500_01/appdev.920/a96590/adg09dyn.htm]
Hope this helps!!
Regards,
Adarsh

Bug while using string parameter values in postgresql query

Hi,
I have the following query for the postgresql database:
Code:
<queryString><![CDATA[SELECT
evt_src_mgr_rpt_v."evt_src_mgr_name" AS esm_name,
evt_src_collector_rpt_v."evt_src_collector_name" AS collector_name,

evt_src_rpt_v."date_created" AS date_created,
CASE WHEN $P{mysortfield} = 'evt_src_mgr_name' THEN evt_src_mgr_name
WHEN $P{mysortfield} = 'evt_src_collector_name' THEN evt_src_collector_name
WHEN $P{mysortfield} = 'evt_src_grp_name' THEN evt_src_grp_name
ELSE evt_src_name END as sort
FROM
"evt_src_mgr_rpt_v" evt_src_mgr_rpt_v
LEFT JOIN
"evt_src_collector_rpt_v" evt_src_collector_rpt_v
ON EVT_SRC_MGR_RPT_V."evt_src_mgr_id" = evt_src_collector_rpt_v."evt_src_mgr_id"
LEFT JOIN
"evt_src_grp_rpt_v" evt_src_grp_rpt_v
ON evt_src_collector_rpt_v."evt_src_collector_id" = evt_src_grp_rpt_v."evt_src_collector_id"
LEFT JOIN
"evt_src_rpt_v" evt_src_rpt_v
ON evt_src_grp_rpt_v."evt_src_grp_id" = evt_src_rpt_v."evt_src_grp_id"
LEFT JOIN
"evt_src_offset_rpt_v" evt_src_offset_rpt_v
ON evt_src_rpt_v."evt_src_id" = evt_src_offset_rpt_v."evt_src_id"
WHERE
$P!{mysortfield} LIKE '$P!{searchvalue}' || '%']]></queryString>
That is I try to select only the records where the field which is
selected by user as report parameter ($P{mysortfield}) contains data
starting with the text entered by user as a report parameter
($P{searchvalue}).
When I try to run the report in iReport with active connection to the
database the report is generated as expected.
But when I try to run the report from Sentinel Log Manager I get the
following error: "java.lang.String cannot be cast to
net.sf.jasperreports.engine.JRValueParameter".
After several detailed debug sessions I finally came into a conclusion
that this error is related to the use of parameter values (
$P!{mysortfield} and $P!{searchvalue} ).
I even tried using the following WHERE clause (which emulates the
queries as used in standart reports (especially at VendorProduct related
SQL queries ) with no success:
Code:
WHERE
($P{mysortfield} = 'evt_src_mgr_name' AND evt_src_mgr_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_collector_name' AND evt_src_collector_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_grp_name' AND evt_src_grp_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_name' AND evt_src_name LIKE ($P{searchvalue} || '%'))
Any suggestions?

Thank you for the suggestions:
While trying to implement your suggestions I realized that there was a
error at the parameter name I used inside the where clause (it should be
$P{searchfield}).
Here are my results:
Code:
vt_src_mgr_name LIKE '%' || '%'
worked as expected.
Code:
$P{searchfield} LIKE '%' || '%'
produced PDF but wrong output.
Code:
$P!{searchfield} LIKE '%' || '%'
resulted with the error "java.lang.String cannot be cast to
net.sf.jasperreports.engine.JRValueParameter" and no PDF.
Then I tried the following where clause which resulted in exactly as
expected PDF:
Code:
WHERE
($P{searchfield} = 'evt_src_mgr_name' AND evt_src_mgr_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_collector_name' AND evt_src_collector_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_grp_name' AND evt_src_grp_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_name' AND evt_src_name LIKE ($P{searchvalue} || '%'))
As a summary:
* The query which works in iRepord do not work in Sentinel Log
Manager.
* I found a workaround for my case.
* I did not checked, but the reports provided in Sentinel RD which use
the same technique for VendorProduct parameter (i.e. the reports with
query string containing
Code:
LIKE ($P{VendorProduct} || '%')
will most probably not work as expected IF Sentinel RD uses the same
code as Sentinel Log Manager.

Why order by clause maintains column number values instead of column names

why order by clause maintains column number values instead of column names ?

we can use oder by 1,2 as column number
UGNo one said that it can't be used. What's your point?
To OP: It can be written with the column's 'select list positional number' just because for the support of laziness. :)
There's no difference between 'ORDER BY name, address' and 'ORDER BY 1,2'.

Crystal Report - NULL values mapped to Column names in reports

Hai,
I am using rows of data retrived from the SQL Server 2005 Express and sometimes the column names are NULL , I want to set a default value to this NULL value and set it as Data axes label / Group axes values, can some one please help me with this issue.
Thank you in advance.

I resolved this issue myself, this can be set as other Data Labels, Group Label or Series Riser's properties too, left-click twice until the blank item is selected and then right click and select "Edit Axis Label" item and here it can edited with the new value(text).

How to insert parameter value into multiple columns and rows

Hi All,
I have one procedure insert_tab and I am passing
100~101~102:103~104~105:106~107~108 as a parameter to that procedure. I wanted to insert each numeric value into one column. The output of the table should contain

Referencing an item value as a column name

Hello
I am trying to make an interactive report region source, where in the where clause there should be a column name that is built somehow like this : "table_name".:P9_LABEL (this doesn't work ;(ORA-01747: invalid user.table.column, table.column, or column specification) ). P9_LABEL is an item in the same page, which contains the column name. What is the right way to do this ?
Tiina

I think in that case you would need a function returning SQL Query and interactive reports (as far as I know) do not support that. Maybe, you could use a pipelined function for that (not sure). See this example on pipelined functions:

SSMS 2012: Using CTE in a query - Invalid column name 'EmployeeID' !!??

Hi all,
From Page 88 of the Book "SQL Programming & Database Design Using Microsoft SQL Server 2012" written by Kalman Toth, I copied the following code of Using CTE in a query:
-- CTETest2.sql /// saved in C:\My Documents\SQL Server Management Studio\
----Page 88 of Book by Toth === Using CTE in a query ----- 13 March 2015
--Using CTE in a query
;WITH CTE (SalesPersonID, NumberOfOrders, MostRecentOrderDate)
AS (SELECT SalesPersonID, COUNT(*), CONVERT(date, MAX(OrderDate))
FROM Sales.SalesOrderHeader GROUP BY SalesPersonID )
--Start of outer (main) query
SELECT E.EmployeeID,
OE.NumberOfOrders AS EmpOrders,
OE.MostRecentOrderDate AS EmpLastOrder,
E.ManagerID,
OM.NumberOfOrders AS MgrOrders,
OM.MostRecentOrderDate AS MgrLastOrder
FROM HumanResources.Employee AS E
INNER JOIN CTE AS OE ON E.EmployeeID = OE.SalesPersonID
LEFT OUTER JOIN CTE AS OM ON E.ManagerID = OM.SalesPersonID
In my SQL Server 2012 Management Studio, I executed this set of code and I got the following fatal error:
Msg 207, Level 16, State 1, Line 16
Invalid column name 'EmployeeID'.
I have no clues why I got this error message in this .sql trial of my second practice in doing CTE. Please kindly help and let me know where I made mistake and how to resolve this problem.
Thanks in advance,
Scott Chang

Hi scott_morris-ga, Thanks for your nice response.
I changed EmployeeID to BusinessEntityID as you pointed out and executed the revised code:
-- CTETest2.sql /// saved in C:\My Documents\SQL Server Management Studio\
----Page 88 of Book by Toth === Using CTE in a query ----- 13 March 2015
--Using CTE in a query
;WITH CTE (SalesPersonID, NumberOfOrders, MostRecentOrderDate)
AS (SELECT SalesPersonID, COUNT(*), CONVERT(date, MAX(OrderDate))
FROM Sales.SalesOrderHeader GROUP BY SalesPersonID )
--Start of outer (main) query
SELECT E.BusinessEntityID,
OE.NumberOfOrders AS EmpOrders,
OE.MostRecentOrderDate AS EmpLastOrder,
E.ManagerID,
OM.NumberOfOrders AS MgrOrders,
OM.MostRecentOrderDate AS MgrLastOrder
FROM HumanResources.Employee AS E
INNER JOIN CTE AS OE ON E.BusinessEntityID = OE.SalesPersonID
LEFT OUTER JOIN CTE AS OM ON E.ManagerID = OM.SalesPersonID
I got 2 new error messages:
Msg 207, Level 16, State 1, Line 17
Invalid column name 'ManagerID'.
Msg 207, Level 16, State 1, Line 12
Invalid column name 'ManagerID'.
I have no ideas what should be used to replace 'ManagerID' in my revised code. Could you please help again and give me the right thing to replace the 'ManagerID'? By the way, where in the AdventureWorks do you find the right things? Please enlighten
me in this matter.
Many Thanks again, Scott Chang

Using "$" character with Oracle; getting "invalid column name"

I am running the following query against an Oracle database:
select price from my_table
where index_name = 'CGPR_C$'
and settlement_date = to_date('02/19/2001','MM/DD/YYYY')
The query runs fine in TOAD.
If I run this query from my java code, I get an "invalid column name" exception.
If I take out the "$" character, the query runs fine.
I've tried inserting the "$" in as unicode, escaping out the character, ||chr(36)||, and nothing works.
Please help!
Ashley

Look up your Oracle SQL documentation and find out how to use column names that would otherwise be invalid. Some databases allow you to put column names, table names, and so on in square brackets (e.g. [CGPR_C$]) but I don't know Oracle's syntax.

How to get warning by using the previous value of the column and new value

Hi all,
Suppose the column A has the true and when I click on button which also sets the value of the column as true I should dispaly warning that column a is already true.How can I achieve this.How to store the original value of the column and then check wirth the new value.
Thanks in advance.

You dont have to store the value anywhere
You can do this from setMethod of EOImpl.java
eg:
void setAttributeXXX(String Value)
// value contains new value
// getAttributeXXX() contains oldValue
if (value.equals(getAttributeXXX()))
// Verify value is > 0 if (value.compareTo(0) <= 0)
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT, // indicates EO source
getEntityDef().getFullName(), // entity name
getPrimaryKey(), // entity primary key
"AttributeXXX", // attribute Name
value, // bad attribute value
"AK", // nessage application short name
"FWK_TBX_T_EMP_SALARY_REQUIRED"); // message name
setAttributeInternal(AttributeXXX, value);

Disable SSRS parameter using another parameter value

Hello, I'm developing using SQL Server 2008 R2 standard edition & I would like to disable 2 parameters (parRestraint and par RestrantPosition) by using another parameter, "Restraint Filters On Off".
When the user loads the report up, I want the On Off filter to be defaulted to off, and the former 2 params to be disabled, but the default value to be visible for them, which are NDX tuples.
parRestraint default value = [Incident].[Incident Restraint].[All] (from MDX dataset)
parRestraintPosition default value = [Incident].[Incident Restraint Position].[All] (from MDX dataset)
ANy advice appreciated !

An additional pierce of information is that the data for the parameters comes from an Analysis Services cube (Restraint and Restraint Position are attributes of the Incident dimension).
I would like to be able to set a null value for default values of Restraint and Restraint Position parameters, but SSRS won't allow me to do this.
My code for Restraint default param value
=IIF(Parameters!IncidentYN.Value = -1,
"null","[Incident].[Incident
Restraint].&[UnAssigned]")
or
=IIF(Parameters!IncidentYN.Value = -1,
null,[Incident].[Incident
Restraint].&[UnAssigned])
Both example fail. I think that this could be achieved with a relational database as the data source for the parameters, but need someone to confirm this.
Thanks everyone.

Get value based on column names for custom metadata field of Webcenter Content

In UCM, I created a custom metadata field of type Text. I then enabled optlist in that field. I populate values to the optList, I am using a View. The View has three columns. Let us call them ID, Key, Value. OptList displays the Keys in its list. I then create a Content (Content ID: MyContent) in Webcenter Content and choose values from OptList for my new metadata field (MyField).
From Webcenter Portal, I am populating a selectOneChoice with values of MyField in the Content ID: MyContent. Remember from previous step, the values populated in selectOneChoice is the list of values selected from optList field MyField. This optList is in-turn populated from View. After the user selects a value in selectOneChoice, in Javascript, I need to alert a message in this format "value chosen - corresponding value from View of optList that populates MyField"
I think an example will be useful:
Here is a View that I created in Configuration Manager applet in Admin Applets of Webcenter Content:
ID | State | Capital
1 | North Carolina | Raleigh
2 | California | Sacramento
3 | Illinois | Chicago
Then, I create a Custom Field (Name: MyField). MyField is an optList the values are populated from View created above. The internal value and display value are both State. Then I Check-In a new content with Content Id: MyContent. For MyContent, I select these values from OptList for MyField: {North Carolina, Illinois}.
In my Webcenter Portal application, I create a Content Presenter Taskflow. I configure it as a single item content presenter. I assign MyContent as Content Id. Then, in templateView, I get all values of MyField in MyContent and display them as selectOneChoice. I created a javascript function that would get the value that user selected in selectOneChoice. In the View created in Webcenter Content's Configuration Manager (above), there is a value corresponding to each value displayed. So, for the selected value, I need to get the corresponding Capital and display it in my alert message.
From Javascript, how can I get the value of Capital, given I have the value of State.

Hi.
The idea to achieve your requirement is next:
Create a helper manage bean that will be call as Map access: #{stateUtil['Calofironia']} (it will return Raleigh). This value will be get calling GET_SCHEMA_VIEW_VALUES IDC service using RIDC in your manage bean.
Pass the result of #{stateUtil['statename']} to your JavaScript function using <af:clientAttribute.../>
I hope this information help you.

Use session state values to set column value during insert/update

I am building an APEX 4.2 application that uses the canned Data Loading control to upload csv data to a table. I have modified the 'Select Data Source' page of the workflow and it now contains three LOV's that the user selects values from. The selected values are stored in Session State. As I'm new to APEX, I do not know how to reference Session State objects in the context of the Data Loading workflow so that the appropriate columns are set with the correct values. My assumption is that the columns that are apart of the insert statement reside in a collection somewhere. I just don't know how to loop through the collection, determine the correct column, and then set that column's value equal to the corresponding LOV value in Session State.

Scott,
This is in version 2.2.1 and there are no caching features available.
The application does require login.
I'm playing around with the APP_UNIQUE_PAGE_ID right now but I am finding that even in the builder if I edit the attributes of a report column and then try to edit another column it will bring up the last column I edited. Even if I use the record navigation buttons next to the Apply Changes button it will keep bringing me the same page over and over unless I constantly refresh the pages.

Dynamically defined GeoRaster theme using WMS parameter values

Hi everyone,
In addition to dynamically defining a GeoRaster theme using SQL (which is documented by Oracle), is it possible to somehow access the WMS values of parameters in the WMS query which is accessing the theme? For example, can I grab the BBOX values from the WMS REQUEST and use that in my dynamic SQL statement?
My goal for doing this is to select the most appropriate pyramid level of the raster imagery given the map scale of the WMS request.
My other question is when using a GeoRaster theme containing a SQL statement, will the MapViewer WMS engine still automatically select imagery from all and any relevant georaster image that has a portion within the BBOX of the query?
Cheers,
MH

A Georaster object can have pyramid levels, and in MapViewer you can define a pyramid level for a theme. If you define this parameter, then for any zoom level that you render, MapViewer will read the pixels for this pyramid level. Depending on the zoom level, you may be loading unecessary data due to the screen resolution. If you do not define the pyramid level, MapViewer will calculate the actual screen resolution given the query and device windows, and will load the pixels for the pyramid level that is closest to the actual screen resolution, resulting on a better performance.

Hi,
I am having difficulty using Crystal Reports Server XI to deploy reports that were made in Crystal Reports XI.
When I create a report that uses a dynamic parameter listing, I get the follow error when I try to install it onto the server:
Failed to read data from report file C:\WINDOWS\Temp\myreport.rpt. Reason: Failed to read parameter object
But if I were to use a static parameter listing, the server will load up the report just fine. Can you please tell me what I am doing wrong and I need to do to fix the problem. As many details as possible would be helpful.
Thanks,

Does the issue happen with the built in administrator account? I believe this is a permissions issue and the permissions need to be set in business views.
