Issue with 'null' value in Formulas

Hi all - I have a PDF in which I'm performing various calculations, basic addition and subtraction. I'm using the following Custom Calculation Script:
this.getField("Amount, Total Revenue Allocated to Maintenance Expenses").value = this.getField("Amount, Endowment Care Fund Income - Schedule H").value + this.getField("Amount, Special Care Fund Income - Schedule H").value + this.getField("Amount, Income from Cemetery Operations").value + this.getField("Amount, Other Sources Please Specify").value;
My issue is that when someone deletes a value in one of the fields (which I guess causes the field to be 'NULL'), the calcualtion doesn't work....so in other words if I have the following:
Field 1: 10
Field 2: 20
Field 3: 30
Field 4: 40
When adding this should result in 100.....however if one were to delete the value in field 2, my calcualtion then produces 103,040....the formula doesn't know how to process the NULL value of course, so it concatenates the numbers.
How do I get around this? Do I need more JavaScript, and if so is there a good example somewhere on how to code it?
Thanks, Steve

leahfst,
If these dates are complementary (as in 'either date1 either date2 has a value) you could transform the dates to text, merge these two fields (one being empty) and convert the result back to a date:
Date(ToText({CnFGf_1.CnFGf_1_Date}) & ToText({CnFGf_2.CnFGf_2_Date}))
If these dates can both have a value (or not), it is helpful to know a null-value for dates is equal to Date(0000,00,00). In this situation, there can be the following situations:
1. Both dates are empty. Your result will obviously be an empty date.
2. {CnFGf_1.CnFGf_1_Date} has a value, {CnFGf_2.CnFGf_2_Date} is empty.
3. {CnFGf_1.CnFGf_1_Date} is empty, {CnFGf_2.CnFGf_2_Date} has a value.
4. Both dates have a value. You will have to choose which date should be used.
For any of these four situations, you can check the date to have a value using:
IF {CnFGf_1.CnFGf_1_Date} = Date(0000,00,00)
and so on..

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

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.

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.

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 :)

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.

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.

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.

Issue with Negative Value for Total valuated stock 0VALSTCKQTY.

Hi Experts,
we loaded the Cube with datasources 2LIS_03_BX, 2LIS_03_BF and 2LIS_03_UM.
We mapped the quanity field from 2LIS_03_BF in transformation either into Key figures "Quantity issued from valuated stock" (0ISSVALSTCK) or "Quantity received into valuated stock" (0RECVALSTCK ) of the cube.
For obtaining the Total Valuated stock, we used the Key figure 0VALSTCKQTY. This key figure is having the Inflow and Out flow values as 0RECVALSTCK and 0ISSVALSTCK. When i tried to check the content of 0VALSTCKQTY, the key figure 0VALSTCKQTY is not present in the infoCube content. I understood that the value for this key figure would be calculated at the time of query execution with the formula
{ Last obtained Valuated stock + (Received Valuated Stock u2013 Issued Valuated Stock ) }.
The issue is the first records in the query is obtained with negative value for the total valuated stock 0VALSTCKQTY even though the values of Received Valuated Stock and Issued Valuated Stock are with Zero. Could any one please help me on how the first record in the query is with a negative value eventhough the inflow and out flow fields of it are with Zero.
Many Thanks in advance.
Jeswanth

Hi Srini,
I observed an interresting reason for the stock being with negative in the first record.
Issue : While executing the BEx report, we have the first record with a negative value.
Let me explain with an example
Material : XYZ
Plant      : A
Date of Stock Initialization for data source 2LIS_03_BX -
> 12th April 2009.
So on 12 Th April 2009 consider that we have a stock in store with a value of 2640.
Then we have loaded wih Data source 2LIS_03_BF for all Historic Movement types.
At the time of query execution we will have the first record with a negative of available stock present on the day of initialization .
So, as we have initilized the data source 2LIS_03_BX on 12 th April 2009, we have at that time a stock of 2640 in availability.
Exactly with the same value of 2640, we are having a negative value i.e. -2640.
and also one more point to be noted is ...as we have initialized the data source 2LIS_03_BX on 12 th APril 2009...it has created a
opening balance of 2640 on the day of initiailization i.e on 12 th April 2009 in infocube....(which is an extra record...)...so if the previous record of 12,04,2009 is having some value in it..then it will get added to 2640 EA..which will give incorrect stock
So in the query the records will appear in the below following manner
Calendar Day     Total stock                                                                Received stock                                          Issued Stock
28.12.2005 ---> - 2640 EA
29.12.2005 --->    2000 EA                                                                       640 EA                                                        0
10.04.2009 --->      0                                                                                0                                                               2000 EA
11.04.2009 -
>    0                                                                                0                                                                0
                             (For making
                              the earlier record of initilization to 0 a negative value -2640 EA is created in the first record )
12.04.2009 (Initializtion day) ---> 2640 EA                                                 0                                                                0
13.04.2009
the day before initialization the total stock will be 0 due to the negative effect introduced by the first record and from the day of initialization the records will be the accurate values... On 12 th april 2009 we can see that a stock of 2640 is brought into the total stock. In fact if there is no negative value i.e. -2640 in the first record then ...the value on 11.04.2009 will be 2640 Ea and this will get summed up with the Opening balance of 2640 EA created by 2LIS_03_BX on the day of intitialization. So on 12 .04. 2009 the total stock will be shown as 5280 EA...so in order to prevent the double value only we observed that the first record is created with the negative of available stock present on the initialization ...to make the record before the day of initialization i.e. 11.04.2009...to be 0...so that from 12 th April 2009 ..will start to see the actual total stock in the query result...
This is happening only if we use both the data sources 2LIS_03_BX and 2LIS_03_BF for loading into BW.....
If we load alone by 2LIS_03_BF ...then as 2LIS_03_BX is ruled out in the loading...then no negative of available stock will be created ...because there will be bno opening balance created on the day of initialization.....and the opeing balance available will be flowing into consecutive records due to the movement types and 12 th April 2009 will be shown with avaialable total stock of 2640 EA.
Kindly let us know your opinions on this...
Thanks.

Oracle 11g decode issue with null

Hi,
we want to migrate from Oracle 10g to Oracle 11g and have an issue with decode.
The database has the following character set settings:
NLS_CHARACTERSET = AL32UTF8 in Oracle 11g and UTF8 in Oracle 10g
NLS_NCHAR_CHARACTERSET = AL16UTF16
If I try a select with decode which has null as first result argument I will get a wrong value.
select decode(id, null, null, name) from tab1;
("name" is a NVARCHAR2 field. Table tab1 has only one entry and "id" is not null.)
This select returns a value with characters which are splitted by 0 bytes.
In Oracle 10g the value without 0 bytes is delivered.
If I suround the decode with dump I get following results:
select dump(decode(id, null, null, name), 1016) from tab1;
Oracle 10g: Typ=1 Len=6 CharacterSet=AL32UTF8: 4d,61,72,74,69,6e
Oracle 11g: Typ=1 Len=12 CharacterSet=US7ASCII: 0,4d,0,61,0,72,0,74,0,69,0,6e
NLS_LANG has no effect on the character set of 'null' in Oracle 11g.
Non null literals work:
select dump(decode(id, null, 'T', name), 1016) from tab1;
Oracle 10g: Typ=1 Len=6 CharacterSet=UTF8: 4d,61,72,74,69,6e
Oracle 11g: Typ=1 Len=6 CharacterSet=AL32UTF8: 4d,61,72,74,69,6e
select dump(decode(id, null, N'T', name), 1016) from tab1;
Oracle 10g: Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
Oracle 11g: Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
Here the scripts for creating the table and the entry:
create table tab1 (
id NUMBER(3),
name NVARCHAR2(10)
insert into tab1 (id, name) values (1, N'Martin');
commit;
Is it possible to change the character set?
Could you please help me?
Regards
Martin

This doesn't have the problem.looks this doesn't solve the problem (of returning a value with characters which are splitted by 0 bytes):
SQL> select * from v$version where rownum = 1
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
1 row selected.
SQL> select dump(decode(id, null, null, name), 1016) from tab1
union all
select dump(case id when null then null else name end, 1016) cs from tab1
DUMP(DECODE(ID,NULL,NULL,NAME),1016)
Typ=1 Len=12 CharacterSet=US7ASCII: 0,4d,0,61,0,72,0,74,0,69,0,6e
Typ=1 Len=12 CharacterSet=AL16UTF16: 0,4d,0,61,0,72,0,74,0,69,0,6e
2 rows selected.You need to explicitly convert the third parameter to char:
SQL> select dump(decode(id, null, to_char(null), name), 1016) from tab1
DUMP(DECODE(ID,NULL,TO_CHAR(NULL),NAME),1016)
Typ=1 Len=6 CharacterSet=WE8MSWIN1252: 4d,61,72,74,69,6e
1 row selected.

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

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.
