Does Endeca Integrator Loads Attribute with Null value?

I have a table in DB , with a column , lets say, supply_id. This is null for all rows.
When i load data from this table using clover ETL graph and lets say source this data to another table , will my final table will have a column as supply_id?
Or will this column will get dumped.
I discussed on clover etl forum, it seems this column will be picked. However, when we use EID Intgrator the column is getting dropped always..
I tried a sample graph passing an attribute having null value and having property nullable=true. But still it was dropped.
I posted same question on clover etl forum long back. They explained its not something out of the box from Clover but a change Oracle EID made to the engine.
http://forum.cloveretl.com/viewtopic.php?f=4&t=6508
Could you please confirm if this is expected behavior and if so , is there any workaround?

Yes, if an attribute doesn't contain any values that attribute doesn't exist in the Endeca Server. Why do you want an attribute that doesn't contain values?

Pro*C & SQLDA with NULL value for predicate column

Hi: I am using a C program to update a table via a dynamic sql (method 4) and SQLDA. In the update statement predicate, I have place holders (as in TBLCOL=:C000). One of the columns in the predicate contains null values, so I set L[n] = 0, V[n] = pData (which pData[0] = '\0'), *(I[n]) = -1, and T[n] = 5 (for text). I cannot find the row that I know is there.
I cannot change my statement to contain TBLCOL IS NULL, since I don't know ahead of time if I'm looking for rows with null values for this column. The Pro*C manual says that by setting the appropriate *(I[n]) = -1, it indicates to Oracle to simulate the "IS NULL" clause, and update the appropriate rows. In my case, I receive 1403 as SQLCODE when I use TBLCOL=:C000 vs TBLCOL IS NULL. What am I doing wrong? Thank you for your help.

You should include these columns as well;
ChangeType (see mxi_changetype)
ValOwner (repository)
UserID ("jobid=<>", usermskey, GUI (mmc), DG (dyngrp), reconcile)
IdAudit (This is the event task (add and del member for assignments)
ParentAuditId (AuditID of parent which last updated the attribute, not consistent)
ChangedBy (Holds the MSKEY of the user which last changed the attribute)
ExpiryTime
to make sure you get a fuller picture of the audit record.

JDBC MS Access--- cannot extract entry with null value with data type Meta

I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexception

The question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.

did you try "merged dimensions" in the Web Intelligence Report ?

Sql query slowness due to rank and columns with null values:


Sql query slowness due to rank and columns with null values:
I have the following table in database with around 10 millions records:
Declaration:
create table PropertyOwners (
[Key] int not null primary key,
PropertyKey int not null,
BoughtDate DateTime,
OwnerKey int null,
GroupKey int null
go
[Key] is primary key and combination of PropertyKey, BoughtDate, OwnerKey and GroupKey is unique.
With the following index:
CREATE NONCLUSTERED INDEX [IX_PropertyOwners] ON [dbo].[PropertyOwners]
[PropertyKey] ASC,
[BoughtDate] DESC,
[OwnerKey] DESC,
[GroupKey] DESC
go
Description of the case:
For single BoughtDate one property can belong to multiple owners or single group, for single record there can either be OwnerKey or GroupKey but not both so one of them will be null for each record. I am trying to retrieve the data from the table using
following query for the OwnerKey. If there are same property rows for owners and group at the same time than the rows having OwnerKey with be preferred, that is why I am using "OwnerKey desc" in Rank function.
declare @ownerKey int = 40000
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from (
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
) as result
where result.[Rank]=1 and result.[OwnerKey]=@ownerKey
It is taking 2-3 seconds to get the records which is too slow, similar time it is taking as I try to get the records using the GroupKey. But when I tried to get the records for the PropertyKey with the same query, it is executing in 10 milliseconds.
May be the slowness is due to as OwnerKey/GroupKey in the table can be null and sql server in unable to index it. I have also tried to use the Indexed view to pre ranked them but I can't use it in my query as Rank function is not supported in indexed
view.
Please note this table is updated once a day and using Sql Server 2008 R2. Any help will be greatly appreciated.

create table #result (PropertyKey int not null, BoughtDate datetime, OwnerKey int null, GroupKey int null, [Rank] int not null)Create index idx ON #result(OwnerKey ,rnk)
insert into #result(PropertyKey, BoughtDate, OwnerKey, GroupKey, [Rank])
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
go
declare @ownerKey int = 1
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from #result as result
where result.[Rank]=1
and result.[OwnerKey]=@ownerKey
go

JDBC Receiver Adapter with Null Value

HI,
I have configured ID for JDBC Receiver. In my communication channel, I already check Integration of Empty String Values = Null Value. However, when I check the result from audit log, it still shows that SAP XI sends the null value to database. In my understanding, it should not send the field which has null value (It shouldn't be included in sql statement).
I check this with other scenario. With the same check at Integration of Empty String Values = Null Value, it doesn't send null value to database. It happens only with my first scenario.
Have anyone ever been through this before? Any suggestion please?
Thanks,
Pavin

Hi,
1. The occurrence is 0...1
2. This is the first result with null value (Please see field Error)
UPDATE EXPCRM_T_CustomerProfile SET RequestID=455, RecordNo=1, SAPCustomerCode=0001000344, Error=NULL, Status=2, UpdateDateTime=12/03/2008 13:45:03 WHERE (RequestID=455 AND RecordNo=1)
Then, I change the option from Null Value to Empty string. This is the result.
UPDATE EXPCRM_T_CustomerProfile SET RequestID=455, RecordNo=1, SAPCustomerCode=0001000344, Error=', Status=2, UpdateDateTime=12/03/2008 13:46:12 WHERE (RequestID=455 AND RecordNo=1)
Field Error Change from NULL to '
The expected result from me is that field Error should not exist at all. Please help.

Need help with NULL values in Crosstables

Hello everybody,
I need some help with NULL values and crosstables. My issue is the following:
I have a query (BW - MDX-Query) that gives me turnover measures for each month. In Crystal Reports I choose crosstable to display this whereby I put all month in columns and all turnover-measures in rows. Each month that has a value (measures are not empty) is chown in the crosstables rows. So far so good. The problem occures when there are month that actually have no values (measures are empty). In that case these months are not chown in columns. But I need CR to display these columns and show the value 0. How can I do that?

Hi Frank,
Cross tab shows the data based on your column and these column fields are grouped and based on the group it will show your summaries.
If there is no data for any of your group it will not display that group. In this case you will have to create a standard report which should look like cross tab and to get zero values you need to write formulas .
Example if you want to display Moth wise sales :
if Month() = 01 Then
sum() else 0
Now this formula will check if your month is Jan, then it will sum up the values else it will display zero value.
This is possible only through standard report not with Cross Tab.
Thanks,
Sastry

Range interval partitioning with null value

Hello,
I have question, how can I create table with partition and after that I will insert null value in the partition key like this kind of
range interval partitioning with null value.
I have Oracle 11g.
Thanks
Mohammed

Thank you, but my question is about range interval not for range?http://docs.oracle.com/cd/E11882_01/server.112/e25523/partition.htm#VLDBG00220
A MAXVALUE literal can be defined for the highest partition. MAXVALUE represents a virtual infinite value that sorts higher than any other possible value for the partitioning key, *including the NULL value.*
So since you're trying to partition by interval (which doesn't support a MAXVALUE clause) you're out of luck.
There's probably fancy hacks and what not you could try to implement, but i'm not about to recommend any of those here :)

Clarification needed on the behaviour of count with null values

Hi friends,
I am confused about the result given by the count aggregate function when dealing with null. Please can anybody clarify about that to me. Here is what i tried
CREATE TABLE Demo ( a int);
INSERT INTO Demo VALUES
(1),
(2),
(NULL),
(NULL);
SELECT COUNT(COALESCE(a,0)) FROM Demo WHERE a IS NULL; -- Returns 2
SELECT COUNT(ISNULL(a,0)) FROM Demo WHERE a IS NULL; -- Returns 2
SELECT COUNT(*) FROM Demo WHERE a IS NULL; -- Returns 2
SELECT COUNT(a) FROM Demo WHERE a IS NULL; -- Returns 0
Please can anybody explain me why the result is same for the first three select statements and why not for the last select statement. And what does COUNT(*) actually mean?
With Regards
Abhilash D K

There is a difference to the logic when using a column name versus "*" - which is explained in the documentation (and reading it is the first thing you should do when you do not understand a particularly query/syntax). When you supply a column
(or expression) to the count function, only the non-null values are counted. Isnull and coalesce will obviously replace a NULL values, therefore the result of the expression will be counted.
1 and 2 are effectively the same - you replace a null value in your column with 0 and each query only selects rows with a null column value. The count of non-null values of your expression is therefore 2 - the number of rows in your resultset.
3 is the number of rows in the resultset since you supplied "*" instead of a column. The presence of nulls is irrelevant as documented.
4 is the number of non-null values in the resultset since you DID supply a column. Your resultset had no non-null values, therefore the count is zero.

How to take the Average of a DATEDIFF column with NULL values?

I am building an SSRS report that can display the average of a calculated datediff column in dd/hh/mm format with the following formula:
=Avg(IIF(Fields!LastCorrectedDate.Value is nothing,0, DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) \(60*24) & ":" & DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) mod (60*24)\60 & ":" & DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) mod (60*24) - (((DATEDIFF("n",cdate(Fields!LastCorrectedDate.Value),cdate(Fields!
LastSignDate.Value)) mod (60*24))\60)*60) ))
SSRS does not raise any errors with the formula and I have used the same formula for other columns without issue. I have noticed that this column includes null values which I think may be the problem. When the reports runs, it returns #ERROR on the column
but does not give a reason why. I am using SSRS report builder with visual basic logic as opposed to embedding SQL. Any help or feedback would be greatly appreciated.

Hi No Ragrets,
According to your description, you want to calculate the average for the date time difference. Right?
In Reporting Services, Avg() function is only available for numeric values. In this scenario, the DateDiff() function to calculate the minutes difference will return a number. So we can do average calculation based on the return values first. Then we format
it as a time. We have tested this case in our local environment. Please try the following expression:
=floor(avg(DateDiff("n",Fields!StartDate.Value,Fields!EndDate.Value))) \(24*60) &":"&
floor(avg(DateDiff("n",Fields!StartDate.Value,Fields!EndDate.Value))/60 mod 24 )&":"&
floor(avg(DateDiff("n",Fields!StartDate.Value,Fields!EndDate.Value))) mod 60
The result looks like below:
If you have any question, please feel free to ask.

Simon Hou

REGEXP_SUBSTR for comma delimited list with null values

Hi,
I have a column which stores a comma delimited list of values. Some of these values in the list may be null. I'm having some issues trying to extract the values using the REGEXP_SUBSTR function when null values are present. Here are two things that I've tried:
SELECT
   REGEXP_SUBSTR (val, '[^,]*', 1, 1) pos1
,REGEXP_SUBSTR (val, '[^,]*', 1, 2) pos2
,REGEXP_SUBSTR (val, '[^,]*', 1, 3) pos3
,REGEXP_SUBSTR (val, '[^,]*', 1, 4) pos4
,REGEXP_SUBSTR (val, '[^,]*', 1, 5) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
POS P POS P P
AAA   BBB
SELECT
   REGEXP_SUBSTR (val, '[^,]+', 1, 1) pos1
,REGEXP_SUBSTR (val, '[^,]+', 1, 2) pos2
,REGEXP_SUBSTR (val, '[^,]+', 1, 3) pos3
,REGEXP_SUBSTR (val, '[^,]+', 1, 4) pos4
,REGEXP_SUBSTR (val, '[^,]+', 1, 5) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
POS POS POS POS P
AAA BBB DDD FFFAs you can see neither of the calls works correctly. Does anyone know how to modify the regular expression pattern to handle null values? I've tried various other patterns but was unable to get anyone to work for all cases.
Thanks,
Martin
http://www.ClariFit.com
http://www.TalkApex.com

Hi, Martin,
This does what you want:
SELECT
   RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 1), ',') pos1
,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 2), ',') pos2
,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 3), ',') pos3
,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 4), ',') pos4
,RTRIM (REGEXP_SUBSTR (val || ','
                    , '[^,]*,', 1, 5), ',') pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);The query above works in Oracle 10 or 11, but in Oracle 11, you can also do it with just REGEXP_SUBSTR, without using RTRIM:
SELECT
   REGEXP_SUBSTR (val, '([^,]*),|$', 1, 1, NULL, 1) pos1
,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 2, NULL, 1) pos2
,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 3, NULL, 1) pos3
,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 4, NULL, 1) pos4
,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 5, NULL, 1) pos5
FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);The problem with your first query was that it was looking for sub-strings of 0 or more non-commas. There was such as sub-string. consisting of 3 characters, starting at position 1, so it returned 'AAA', as expected. Then there was another sub-string, of 0 characters, starting at position 4, so it returned NULL. Then there was a sub-string of 3 characters starting at position 5, so it returned 'BBB'.
The problem with your 2nd query was that it was looking for 1 or more non-commas. 'DDD' is the 3rd such sub-string.

User Created in OIM 11.1.1.5 with null value for mandatory field.

Hi,
We had updated one UDF as mandatory field on OIM user form. We can see the * in front of that field. Now if we create the user using web console (Using UI), we are not able to create the user without giving some value in that UDF as it is mandatory. However if we created the user with UDF value as null using Trusted recon, User sucessfully created in OIM. I had attached the screen shot for that user which create in OIM with UDF value as null.
Is any thing else also need to do to make UDF as mandatory field.
Regards,
Sid

I am not sure this is a bug. Such mandatory checks will often only apply to administrative changes from the GUI. You may not always be able to enforce the same quality of data in reconciled data as you wish to impose for changes made through OIM, and it may prove an issue in some cases if such users could not be reconciled. In this case the use will go into OIM, but you will be forced to populate a value in the mandatory field if you later try to update them in OIM.

How to compare date with null value

Hi
I have a date filed and i assigned that input box with context attribute of type Date.
Here my problem is
when the end user not entered any thing (null ) the i have give some defaul date.
so first in the action method i have to check the date with null
if it is null i have to give default date.
so please let me know how to over come this.
thanks
Mukesh

Hi
You can get your date in your action method like
Date newDate=new Date();
Date myDate= wdThis
                          .wdGetYourComponentNameController()
                                  .wdGetContext()
                                       .currentYourNodeNameElement()
                                                       .getYourDateName();
if ( myDate== null) {
         wdContext.currentContextElement().setYourDateName(newDate);
else{...........//continue your other validations or calling other methods}
