Unpivot task is generating rows for null inputs

So I have a C# application (VS 2012 with .NET4.5) that builds SSIS (SQL2012) packages programatically. the packages can be opened in the designer and they run fine. However, there is one case that is giving me a problem. I have an
OleDb source connected to a table in SQL server. I am using the unpivot task to convert columns in a sparse matrix to an Entity Attribute Value model. So basically, the primary key value of the source table is a pass-through value in the unpivot
task, each column is mapped to the destination column, and the attribute id is hard coded as the pivot key. Like i said this works great EXCEPT i came across one column and a table that was null for all the rows in the table. when I run the package,
it fails with:
OnError,SERVERNAME,DOMAIN\user,{94E83A3B-5386-4712-BEDC-11E35341675F},{94E83A3B-5386-4712-BEDC-11E35341675F},{3187347C-8D44-4D51-8FDB-B5C4159A58B0},9/14/2012 9:48:02 AM,9/14/2012 9:48:02 AM,-1071607780,0x,There was an error with OLE DB Destination.Inputs[OLE
DB Destination Input].Columns[AttributeId] on OLE DB Destination.Inputs[OLE DB Destination Input]. The column status returned was: "The value violated the integrity constraints for the column."
So I set up a data viewer on the data flow and found that the unpivot component was generating rows for every null value. not only that, but the values for the key column and the attribute id (which was hard coded) were also null for all the rows
sent from the unpivot to the ole db destination. I manually created a package with an unpivot for just the column in question and got the same result. then I inserted a value for every row in the table and the same package runs fine.
can someone offer any help or advice on what might be causing this?

its just two columns of data that are concerned. ten character numeric strings in the one and null in the other. the pivot key is hard coded in the unpivot component configuration screen. see the output of the data viewer below. How do
I get Microsoft involved with this?

Trying to test for null input

I am trying to get some input from a user using:
String name="";
BufferedReader in = new BufferedReader(
    new InputStreamReader(System.in));
name = in.readLine();Let's say the user inputs nothing other than the enter key, how can I test for this so that I can write output for it?
In Python, one would use something like:
if not name:
     <then do something>Thanks,
Harlin Seritt

Thanks for the help. When I try it with an empty
string test, nothing happens. However, the test of
name.length() works perfectly. Thanks!
Harlin SerittI'm guessing you tried this, right?
if (name == "") ...
That's not the way to compare string values. The == operator only compares object references when comparing 2 objects. It's an extremely common mistake.

Query to return separate rows for date range including NULLs

I'm trying to write a query that will return all customers from table 1. Table 1 also provides a start date and an end date that may be different for different customers. Left join with Table 2 provides all matches and NULL if NO matches.
If there is any match at all, I do not get the NULLs for other dates. There should be a match for each date from start to end. How can I write the code so that my return will loop thru each date and provide the match or NULL?

Sorry. I am somewhat new to this and am not sure what you are requesting. I receive a return of all customers with the code below but if customer 1 has a start date of 1/1/15 and a stop date of 1/5/15 and a document exists for 1/1/15 and 1/3/15
I do not receive the rows with NUL for 1/2/15, 1/4/15, and 1/5/15 which is what I'm trying to accomplish. If there is no match at all, I only receive the one row with NULL and I would like to see a row for each date from start to stop.

In query properties in BEx query designer you have to do settings to - Display document links
For metadata, master data, and InfoProvider data for a query, you can display links to Documents that you have created for these objects. If documents exist for these objects, the symbol appears next to these objects. If you click on this symbol, you jump to where the document is displayed on the Web.
Highlight the appropriate setting so that the document links for the desired document class are displayed. The document classes are oriented to the various categories of BW objects. InfoProvider data, metadata and master data.

Checklist for daily tasks with multiple rows submitted at once

The goal is to have a list like this. I can pull these in with webparts and List Views, I am sure. The issue I have is submitting these "Tasks" at once with InfoPath.
I have a request for a daily checklist.
I was going to setup some views in InfoPath to get the information for them to fill out, Daily, Weekly, Monthly, Quarterly, Annually.
You select Daily, and a page view in InfoPath shows up with the selections for the checklist. These would be pulling from a SharePoint List.
The issue I have is that I don’t know how to get all the information for, say to be submitted or presented to the form at once.
THe user select Daily from the checkbox on the first / default view, and they are taken to the Daily View and have these checkboxes for items to "check off" once complete:
Daily:
SCOM Health Explorer - Check/Fix
Backup Check/ Fix
Data Center Walkthrough
Security Cameras
VPN's are p
Audit logs on production
Wireless Check
SPAM
Antivirus
AD
My issue is that I would like to have all that information be submitted into a list in the row in which it is submitted.
I know how to submit item ONE at a time, but to have the submit button go through each row in my form...I am at a loss on how to do so. I am looking to make it as easy as possible with the same,
hopefully for the user. I would like to present all the information to them and have them tick off the information, without a drop down to go ... drop down, check, drop down, check, drop down, check.
I just don’t know how to set the items to go into the list in the row in which they're presented after a user "completed" the checklist.
What I have so far:
So I have a custom list that has all these in a single column, title, and I can create a variable, etc. But I am trying to link that information (I am NOT tied to the custom list if it’s not the
best plan!)
But I am trying to take the other custom list, where you submit, that has (from my custom list)
   TaskName   Daily   Weekly   Monthly   Quarterly   Annually   Issues Issues1
TaskName is the SCOM through AD list item (single line of text), Daily, Weekly, etc. through Annually are checkboxes, for “Yes / No" for "is the selection Daily or Monthly, etc.” and the issues
that people may have with the checklist "the issue for AD is that it was corrupted", issues and issues1 are tests to see about putting in “issues1” single line of text and “issues” multiple lines of text (I can NOT pull in multiple lines of text
as an option in Get External Data in InfoPath for the Receive Data. Issues1 shows up (Single line of text)
But NOT Issues (Multiple lines of text) Not earth shattering, if they have to have 255 characters, so be it!
But for me, what I think I want / what would be good, would be to have multiple items show up when they select Daily and the Daily options populate in the view for them to submit, with check for OK or
their putting in any issues into the Issues1 field.
They hit the submit button and are “done!”
The TaskName field is filled out MULTIPLE times, one row for each Daily “task.” The table below would then show the information with Task Name and other rows being filled in over and over again.
I just don’t know how to get the Submit to go line by line and fill in line 1, 2, 3, 4…. From SCOM down to AD.
When the form is presented, it will look something like this to the user, they select the checklist items, (Weekly, Monthly, etc. would be "hidden" if they didn't select that "View") and they'd put in the Issue, IF any.
They'd hit submit and it would submit JUST LIKE THIS! Each row would be a separate row in the SharePoint List, with each value going into it's own option with the TaskName being the name of the task.
   TaskName   Daily   Weekly   Monthly   Quarterly   Annually   Issues Issues1

Input ready query on Multiprovider displays two row for two Infoproviders

Hello experts,
We are using below design to develop an input ready query.
                   Input ready query
                       Multiprovider
Aggregation level 1      Aggegation level 2
Realtime cube 1            Real time cube 2
As we are developing Input ready query on multiprovider, it is automatically creating characteristic named 0INFOPROV at multiprovider and query level. 0INFOPROV contains values of Infoproviders on which multiprovider is created.
char1 cha2 Infoprovider                    key1     Key2
R1       #       Aggregation level 1        10          #
        P1     Aggregation level 2         #              20
During planning, we have to plan on separate row for each infoprovider.
is there any way we can avoid this issue and perform planning on single row for both infoproviders?
Thanks,
Mitesh

Files generated by Web Service Proxy give errors for complex input types

Hi ,
I generated a Java Web Service Proxy using a WSDL file.
The input params are of this fashion -
1) Object 1 have 3 attributes
2) Object 2 having nested Object 2 (yes , again) which has a nested attribute which needs to be passed say Param 1.
When I generate the proxy classes ... Param 1 is referred to as private Object2.Object2 param1 which gives error for the data types.
How can we resolve this .. what should be the correct data type representation for param 1 ?
Thanks

Issue was resolved . Details here - 11g PS2 - WebServiceProxy Class give errors for complex input types

Generate Alerts for Task changes in Project Schedule

Hi,
I would like to generate alerts to all the Project resources when a Task has been revised in Project Schedule. Does MS Project Server 2010 provides this functionality OOTB?
If this not available OOTB, I am planning to write an event handler to generate alerts for Task updates. Would an en event handler for Task level changes impact performance of server?.

Hello,
This is out of the box with the alerts and reminders in 2010, see:
http://technet.microsoft.com/en-gb/library/gg982969(v=office.14).aspx to enable the alerts
and:

Detail entity Location with row key null cannot find or invalidate its owni

I have a simple parent child relationship generated in ADF BC. It's 1 to many...a Work Request can have one or more Locations. If I turn on Composition Association in my assoc definition, I get "oracle.jbo.InvalidOwnerException: JBO-25030: Detail entity Location with row key null cannot find or invalidate its owning entity." The error occurs on the CreateInsert for the Location entity. I've spent hours looking at other solutions and posts about this issue to no avail, including attempting both methods at the below post.
http://radio.weblogs.com/0118231/stories/2003/01/17/whyDoIGetTheInvalidownerexception.html
When I turn off Composition Association and I only add one Location to the Work Request, both the CreateInsert and the Commit work properly. However, if I add a second Location, I get a database constraint violation because ADF BC tries to commit the Location before the Work Request. I have verified that the Work Request Id is populated properly on the Location object, so I'm at a loss at this point. I'm on 11.1.1.3.

Here's the answer in case someone else burns a day on this like I did. Turns out it's a bug (SR submitted), and one that's easy to recreate. The problem is that the parent object isn't "initialized" until after one of it's setters are called. So, what was happening was that I was invoking CreateInsert on the parent, then CreateInsert on the child, then setting properties on the child. So, since I invoked setters on the child first, the child is initialized first, and is thus ADF BC atttempts to insert it first upon commit. The strange thing is that the child had the correct ID for it's associated parent in the logs. Anyways, here are the steps to easily recreate:
1. Model a simple parent child relationship (1 to many, not sure if that matters).
2. Generate the ADF BC components (entity, assoc, vo's, and view links).
3. Ensure that Composition Association is checked in the Assoc object.
4. Add the parent to the app module, then add the child nested below it.
5. Create a new task flow and drop CreateInsert for the parent object onto the flow. Make this the default activity
6. Drop the CreateInsert from the child object onto the task flow, and link it as the outcome of the parent's CreateInsert
7. Drop a page fragment onto the task flow that is bound to the parent object, and make it the third step in the task flow.
8. Drop a commit onto the task flow as the forth step, and place the button on the page that invokes the action corresponding to the commit.
Run it. As soon as the CreateInsert is hit for the child, the error is thrown.
Another associated bug is that (appears to have the same culprit) the child will not be inserted unless one of it's attributes is set (note that you have to turn off Composition Association to get the above error to disappear). However, the child will not be inserted into the database unless one of its setters are invoked.
**The workaround is to use CreateWithParams instead of CreateInsert in order to create the parent object, and pass in at least one parameter to set an attribute on the parent (even to blank). The same must be done on the child unless one of it's setters are invoked.
Note that we're using SQL Server 2008 R2. This appears to be a problem with ADF BC and not with the target DB platform, but I have not tested with Oracle.

How to check for null values in bpel?? Please Help! very urgent!!!

Hello Guys,
I have a problem. I have an external webservice to which I have to post my request. My task is to create an Webservice and Service Assembly to which others would post request and get response. I have to create SA to deploy onto the bus.
The problem is that there are optional elements in the request and response xsd's. In the Response sometimes certain feilds may come or they may not. for Example:- my response could contain a tag like this <firstName></firstName>
I have to copy these feilds in my bpel process from one variable to another.(like in the mapper).
My Question is , Is there any way in BPEL process or BPEL mapper where I could Check for null values in the request or response???
Your inputs would be very helpful.
Thanks
Rajesh

Thanks for replying man :)
Ok I will be more clear.
Here is a snippet of one of the xsd's that I am using.
<xs:element name="returnUrl" nillable="false" minOccurs="0">
                    <xs:annotation>
                         <xs:documentation>Partner specifies the return URL to which responses need to be sent to, in case of
Async message model.
</xs:documentation>
                    </xs:annotation>
                    <xs:simpleType>
                         <xs:restriction base="xs:anyURI">
                              <xs:maxLength value="300"/>
                              <xs:whiteSpace value="collapse"/>
                         </xs:restriction>
                    </xs:simpleType>
               </xs:element>
This means that the return URL field can be there or it may not be there. But if it is there it cant be null because nillable=false. But the whole <returnURL> </returnURL> can be there or it may not be there because minOccurs=0.
My requirement is , if returnURL is there in the response with a value, then in my BPEL mapper I should map it else I should not map it.
Thats the issue.
and Yes kiran, the node be non-existant.
So can you please help me with this.
Thanks
Rajesh

Help on generating token for opendoc url in XI3.1

Hi Guys,
I am trying to get some help in generating token for opendoc url to avoid login while trying to access a report in Infoview.
From a previous post I got this code:
<%@ page import="com.crystaldecisions.sdk.framework.*" %>
<%@ page import="com.crystaldecisions.sdk.exception.SDKException" %>
<%@ page import="com.crystaldecisions.sdk.occa.security.*" %>
<%
boolean loginSuccessful = false;
IEnterpriseSession boEnterpriseSession = null;
String username = "Administrator";
String password = "pwd";
String cmsname = "CMS";
String authenticationType = "secEnterprise";
try {
//Log in.
boEnterpriseSession = CrystalEnterprise.getSessionMgr().logon( username, password, cmsname, authenticationType);
if (boEnterpriseSession == null) {
out.print("Unable to login.");
} else {
loginSuccessful = true;
} catch (SDKException sdkEx) {
out.print("ERROR ENCOUNTERED
" + sdkEx + "");
if (loginSuccessful) {
ILogonTokenMgr boLogonTokenMgr = boEnterpriseSession.getLogonTokenMgr();
String logonToken = boLogonTokenMgr.createLogonToken("", 60, 1);
String infoViewURL = null;
String tokenParam = null;
String redirectURL = null;
infoViewURL = "http://server:8080/InfoViewApp/logon.jsp";
tokenParam = "ivsLogonToken=" + logonToken;
redirectURL = infoViewURL + "&" + tokenParam;
response.sendRedirect(redirectURL);
%>
The problem is I don't know where to put this code in the opendoc.jsp file.
I tried to create a custom OpenDoc.jsp with a above code, leaving the original opendoc.jsp as it is. And used this custom jsp file in the opendoc url. This is taking me to Infoview login page and I see taht a token is created at the end of the url but it is not passed.
Can somebody help me to understand where exactly to put this code in the opendoc.jsp and any correction to this code or additional steps to get it working.
Any help is greatly appreciated

Stratos,
Thanks for your inputs,
I changed the code as you suggested , now my whole code looks like :
<%@ page import="com.crystaldecisions.sdk.framework.*" %>
<%@ page import="com.crystaldecisions.sdk.exception.SDKException" %>
<%@ page import="com.crystaldecisions.sdk.occa.security.*" %>
<%
boolean loginSuccessful = false;
IEnterpriseSession boEnterpriseSession = null;
String username = "user";
String password = "Password";
String cmsname = "Server";
String authenticationType = "secEnterprise";
try {
   //Log in.
   boEnterpriseSession = CrystalEnterprise.getSessionMgr().logon( username, password, cmsname, authenticationType);
   if (boEnterpriseSession == null) {
      out.print("<FONT COLOR=RED><B>Unable to login.</B></FONT>");
   } else {
      loginSuccessful = true;
} catch (SDKException sdkEx) {
   out.print("<FONT COLOR=RED><B>ERROR ENCOUNTERED</B><BR>" + sdkEx + "</FONT>");
if (loginSuccessful) {
   ILogonTokenMgr boLogonTokenMgr = boEnterpriseSession.getLogonTokenMgr();
     String logonToken = boLogonTokenMgr.createLogonToken("", 60, 1);
     //String logonToken = boLogonTokenMgr.getDefaultToken();
   String infoViewURL = null;
   String tokenParam = null;
   String redirectURL = null;
   infoViewURL = "http://Server:8080/InfoViewApp/logon.jsp";
   tokenParam = "ivsLogonToken=" + logonToken;
   redirectURL = infoViewURL + "&" + tokenParam;
   pageContext.forward( "openDocument.jsp?iDocID=" + 4668 + "&token=" + tokenParam);
%>
But I am still getting the Infoview Login Page . The url on the login page is
http://server:8080/OpenDocument/opendoc/logonTrustedAuth.do?appKind=InfoView&iDocID=4668&isApplication=true&token=ivsLogonToken%server%3A6400%4021181JIipxt70VM0kd90v21179JFd4dHn7kW2FKSBi
We can see that a token is being generated and appended to this url but it is not passing the user name and password.
Please let me know what you think about this.

Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks,

Why Excel insert cell block, hasn't input for data input?

Hi
I found a block for insert new row in excel, but there is no input for data input. how should I insert data by this block to excel file? can you help me?
that block name: Excel insert cells
in report generator toolkit
Best Reagards

behzad1 a écrit :
I could work with Excel insert cell block, but when I want add new data to an old row continuation, last row shift downward! while I want add data to old row. anyone can help me?
Nobody will be able to identify the problem without seeing your code. Excel Insert Cells.vi is used to add cells to an existing spreadsheet, not to set the cell value. To do this is a more specific way than the Append Report Text.vi you can use Excel Easy Text.vi or Excel Insert Table.vi. With these vis you can specify the range where you want to insert something.
For your other question (Two different data types) you can use the Excel Set Cell Format.vi to format a range as a date or something else. You will need to use the Excel format specifiers for this.

XMLGEN: Produce XML dump of a table WITH tags for null column values

I am new to generating XML so bear with me....
We have a customer who needs an XML extract of data, including tags for any column that is null.
I created a simple test case below using DBMS_XMLGEN.getXML. The first row (A1) has no null values and thus tags for columns A, BEE and CEE are produced. The second row (A2) has null in column BEE and thus tags for only columns A and CEE are produced.
Is there a way to force a tag for null column BEE in the second row?
create table foo (A varchar2(10), BEE number, CEE date);
insert into foo values ('A1',1,sysdate);
insert into foo values ('A2',null,sysdate);
SELECT DBMS_XMLGEN.getXML('SELECT * FROM foo') FROM dual;
<ROWSET>
<ROW>
<A>A1</A>
<BEE>1</BEE>
<CEE>27-SEP-12</CEE>
</ROW>
<ROW>
<A>A2</A>
<CEE>27-SEP-12</CEE>
</ROW>
</ROWSET>

What's the database version? (SELECT * FROM v$version)
Could you use this instead :
SQL> select xmlserialize(document
2           xmlelement("ROWSET",
3             xmlagg(
4               xmlelement("ROW",
5                 xmlelement("A", a)
6               , xmlelement("BEE", bee)
7               , xmlelement("CEE", cee)
8               )
9             )
10           )
11         -- for display purpose only :
12         as clob indent
13         )
14 from foo
15 ;
XMLSERIALIZE(DOCUMENTXMLELEMEN
<ROWSET>
<ROW>
    <A>A1</A>
    <BEE>1</BEE>
    <CEE>2012-09-27</CEE>
</ROW>
<ROW>
    <A>A2</A>
    <BEE/>
    <CEE>2012-09-27</CEE>
</ROW>
</ROWSET>
Or,
SQL> select xmlserialize(document
2           xmlquery(
3             '(#ora:view_on_null empty #)
4             {
5               <ROWSET>{fn:collection("oradb:/DEV/FOO")}</ROWSET>
6             }'
7             returning content
8           )
9           as clob indent
10         )
11 from dual;
XMLSERIALIZE(DOCUMENTXMLQUERY(
<ROWSET>
<ROW>
    <A>A1</A>
    <BEE>1</BEE>
    <CEE>2012-09-27</CEE>
</ROW>
<ROW>
    <A>A2</A>
    <BEE/>
    <CEE>2012-09-27</CEE>
</ROW>
</ROWSET>
(where "DEV" is my test schema)
If you want to stick with DBMS_XMLGEN, you're gonna have to use PL/SQL and setNullHandling procedure.

Generating token for javacard framework?

Hi,
I am implementing JCRE and it needs to support all APIs that are specified by Oracle JCRE.
It means that beside the coding/ implementation of each class and method, My framework needs to have tokens of each class, method and field as same as tokens of corresponding Oracle API classes, methods and fields.
I don't know if there is a special rule to set token for each framework related item? Or Tokens will be changed if there are changes in framework?
thanks,

Stratos,
Thanks for your inputs,
I changed the code as you suggested , now my whole code looks like :
<%@ page import="com.crystaldecisions.sdk.framework.*" %>
<%@ page import="com.crystaldecisions.sdk.exception.SDKException" %>
<%@ page import="com.crystaldecisions.sdk.occa.security.*" %>
<%
boolean loginSuccessful = false;
IEnterpriseSession boEnterpriseSession = null;
String username = "user";
String password = "Password";
String cmsname = "Server";
String authenticationType = "secEnterprise";
try {
   //Log in.
   boEnterpriseSession = CrystalEnterprise.getSessionMgr().logon( username, password, cmsname, authenticationType);
   if (boEnterpriseSession == null) {
      out.print("<FONT COLOR=RED><B>Unable to login.</B></FONT>");
   } else {
      loginSuccessful = true;
} catch (SDKException sdkEx) {
   out.print("<FONT COLOR=RED><B>ERROR ENCOUNTERED</B><BR>" + sdkEx + "</FONT>");
if (loginSuccessful) {
   ILogonTokenMgr boLogonTokenMgr = boEnterpriseSession.getLogonTokenMgr();
     String logonToken = boLogonTokenMgr.createLogonToken("", 60, 1);
     //String logonToken = boLogonTokenMgr.getDefaultToken();
   String infoViewURL = null;
   String tokenParam = null;
   String redirectURL = null;
   infoViewURL = "http://Server:8080/InfoViewApp/logon.jsp";
   tokenParam = "ivsLogonToken=" + logonToken;
   redirectURL = infoViewURL + "&" + tokenParam;
   pageContext.forward( "openDocument.jsp?iDocID=" + 4668 + "&token=" + tokenParam);
%>
But I am still getting the Infoview Login Page . The url on the login page is
http://server:8080/OpenDocument/opendoc/logonTrustedAuth.do?appKind=InfoView&iDocID=4668&isApplication=true&token=ivsLogonToken%server%3A6400%4021181JIipxt70VM0kd90v21179JFd4dHn7kW2FKSBi
We can see that a token is being generated and appended to this url but it is not passing the user name and password.
Please let me know what you think about this.
