BC4J Objects with PKs based on two columns using multiple sequences

I have implemented a BC4J object that is based on a DB table that has two columns as the primary key. For example Table A's primary key is Group and ID and there is a DB sequence for each Group.
I use the BC4J object using servlets and JSPs and I have been able to implement an Update form.
I now want to implement a Create (New) form. I've read forum postings and info on the help regarding using the SequenceImpl class to override the EntityImpl object's create method as shown below:
protected void create(AttributeList attributeList)
super.create(attributeList);
SequenceImpl mySeq = new SequenceImpl("MY_SEQ",getDBTransaction());
setMyObjectId(mySeq.getSequenceNumber());
But as you can see I need to know the value of the group attribute before I can get the next value sequence:
For new EO belonging in Group1 I need sequence from "GROUP1_SEQ", Group 2 from "GROUP2_SEQ", etc.
I would like to put this code in the Entity Object where it belongs. I guess my problem is simply how to create a new row in the View Object with a passed parameter which is the value of Group.
Thanks in advance!

Angelo:
How is the EO suppose to receive the group id? Is it from the view row? If so, the VO can pass that group id to the EO through the attribute list and calling the
public Row createAndInitRow(AttributeList nvp);
API.
Example code would be:
ViewObject myVO;
// myVO is initialized
AttributeList nvp = new oracle.jbo.NameValuePairs();
// GroupID is the attr name of the Group ID
nvp.setAttribute("GroupID", <some-value>);
Row row = myVO.createAndInitRow(nvp);
If you do that the create(AttributeList attributeList) method of the EO will receive the GroupID value coming from the VO.
Then, you can use that for your sequence.
Thanks.

Update column based on two columns

Hi,
MinValue     MaxValue   Desc
-1                -1
-1                 1
-1                 2
0                  0
0                  1
0                  2
The above is my table which is having three columns MinValue, MaxValue, Desc. First two columns have data and I need to update the 3rd column 'Desc' based on two columns data.
I need to update like,
when MinValue=-1 and MaxValue=-1 then 'NotSpecified'
when MinValue=-1 and MaxValue=1 then 'Up to 1'
when MinValue=-1 and MaxValue=2 then 'Upto 2'
when MinValue=0 and MaxValue=1 then 'At lest 1'
when MinValue=0 and MaxValue=2 then 'At least 2'
when MinValue=0 and MaxValue=3 then 'At least 3'
The data in 'MaxValue' is like 1,2,3,4,5...50. So for each description it should append this value as mentioned above(till 'Up to 50', 'At least 50'). How can I do this with case statement?
Thanks,
Gangadhar

declare @T table ( MinValue int,MaxValue int, [Desc] nvarchar(100) );
insert @T ( MinValue, MaxValue )
values ( -1, 1 ) , ( -1, 1 ) , ( -1, 2), ( 0, 0), ( 0, 1), ( 0, 2)
select *
from @T
update @T
set [Desc] = case
when MinValue=-1 and MaxValue=-1 then 'NotSpecified'
when MinValue=-1 and MaxValue=1 then 'Up to 1'
when MinValue=-1 and MaxValue=2 then 'Upto 2'
when MinValue=0 and MaxValue=1 then 'At lest 1'
when MinValue=0 and MaxValue=2 then 'At least 2'
when MinValue=0 and MaxValue=3 then 'At least 3'
end
select *

Sorting based on two columns in report

Hi,
we have one issue on sorting based on two columns in report.
In the report we are doing sorting on two columns(week_id and stage_name). I have attached the screen shot for the same. The sorting is first done on the week_id and then on the stage_name. The issue comes when we have no data for the stage 1 - Prospect in W1. The stage goes to the second position.
Please suggest if there is any work around to show the 1 - Prospect stage in W1.
Regards,
Ambika Nanda.

what is w1? where is screenshot? and is stage seoncd sort? if so what is the issue?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

Hi,
Use NVL or COALESCE:
NVL (col_a, col_b)
Returns col_a if col_a is not NULL; otherwise, it returns col_b.
Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Parent-Child hierarchy based on two-column key

Hello
Is it possible to create a parent-child hierarchy, if the primary key of the table consists of two columns?
My table looks like:
TRACE_ID | DIAG_ID | SUPER_DIAG_ID
with TRACE_ID and DIAG_ID as PK.
If I define only DIAG_ID as PK, I can add a logical dimension (PC-hierarchy) without problems.
However when I also add TRACE_ID to my PK, I cannot select a member key in the new logical dimension window and therefore not create a logical dimension.
Is this a limitation of OBIEE and I have to merge the two colums (which would be rather bad, as there are FK relations to DIAG_ID) or is there a solution?
Regards
Matthias

Dear Gowtham ,
I am very well aware of the level based hierarchy available in BO .
The issue that i have raised is all about the Parent Child Hierarchy which creates the recursive query.
I.e Every Parent has a child and that child can be parent of some other . (See the original example for more illustration)

Compare two tables based on two columns

Hi,
my tables looks like this:
Desc Table A (account)
Account1_id
Account2_id
name,
empid
Table B (Bill )
BillNo
Advertiserid
agencyid
total vvalue
I need to pick up total value from table B where the unique combination of advertiser-Agency id is the same as the given account1_id -Account2_id combination in table A for each employee id.
In other words my output should be like
Empid | Account_id (should be same as advertiserid)| Account2_id (same as agencyid) | sum(total_value) for this adv-agency combination.....
objective: Get the total value from table B for each unique account1-account2 combination (advertiser-agency in other words) .
I am not sure if I should use a coreelated subquery or how to handle the situation....Right now I am just checking the two columns separately like this:
select.......from a,b
where b.advertiser_id = a.account1_id and b.agencyid = b.account2id
Is it correct to do so? I have a feeling that I am missing something if I join them seperately like this......Any advice on this?
I am using Oracle 10g. Hope I am clear.Please let me know. Thankx in advance.

Unique row based on two columns and single column

Dear Members,
I have a table which contains duplicate rows, for which a query should be able to fetch the unique row from the table. Here the unique is not based on one column, but it should be on two columns and also check for uniqueness on one column.
create table addr ( firstname varchar2(10), lastname varchar2(10), area varchar2(3));
insert into addr values('bob', 'james', '1');
insert into addr values('bob', 'james', '1');
insert into addr values('harry', 'bert', '1');
insert into addr values('jimmy', 'bert', '1');
insert into addr values('sam', 'mac', '1');
insert into addr values('sam', 'knight', '1');
insert into addr values('tom', 'sand', '1');
insert into addr values('cat', 'mud', '1');
The output of query should contain 3 rows.
bob - james
harry - bert or jimmy - bert [ either one of them, but not both ]
sam - mac or sam - knight [ either one of them, but not both ]
tom - sand
cat - mud
SELECT firstname, lastname as total from addr WHERE area = '1' GROUP by firstname,lastname; This does not take of single column duplication..
Any suggestions..

Update multiple rows based on two columns in same row

I have a 1000 rows in a table I would like to update with a unique value. This unique value is a cocatenation of two columns in teh same row.
Each row has a (i) date and a (ii) time and a (iii) date_time column. I would like to update the date_time (iii) column with a cocatenation of the (i) date and (ii) time columns.
I know how I would update a single row but how can I update multiple rows with a cocatenation of each of the two columns - i.e put a different value into the date_time column for each row?

this?

Split one column value into two columns using t-sql

ABC    12C4
BC      A345
CD
XYZ
Thanks,

sql

assuming a static delimiter, and the split will end up with a max of 2 columns, something like this would work. basically you just need to determine where the delimiter is, and then use the left and right functions to find the 2 pieces.
declare @t table(value varchar(10))
insert into @t(value)
values
('ABC-12C4'), ('BC-A345'), ('CD'), ('XYZ')
select
case
when charindex('-', value) != 0 then left(value, charindex('-', value) - 1)
else value
end as col1,
case
when charindex('-', value) != 0 then right(value, len(value) - charindex('-', value))
else ''
end as col2
from @t

Method Validator based on two columns

Hi,
I have a table called FndCities with attributes city_id (pk), country_id (fk) and city_name.
I want to check if a city name is unique for a certain country. For example England can have a city name called "London", but USA might have a city called "London". However neither England not USA can have two "London" cities.
I have implemented a custom method validator and here is the logic:
In the FndCitiesImpl.java i created the following method:
public boolean validateCityName(String data) {
FndCitiesDefImpl entityDef = (FndCitiesDefImpl)getDefinitionObject();
String originalValue = (String)getPostedAttribute(CITYNAME);
Number originalValuePk = (Number)getPostedAttribute(COUNTRYPKFK);
if (data != null && !data.equalsIgnoreCase(originalValue)) {
return !(entityDef.existsByCityName(getDBTransaction(),data, originalValuePk));
return true;
and in the FndCitiesDefImpl.java i have implemented the method existsByCityName(DBTransaction, city_name, country_id).
In the creation method my custom validation works fine, however when i edit a record, becuase the if statement watches for changes in the city name, when changing the Country the validation is not performed. I cannot the country id in the validateCityName method because validation is performed on one column.
How can i achieve this?
Thanks
Antonis

Hi Antonis,
Not sure what you mean again by "JDeveloper does not handle the constraints properly." I have exactly this situation in my application (JDev 10.1.3.1), and I am using a database constraint to enforce uniqueness across 2 columns. I've customized the error messages (see Re: Unique key existence check and ER: ADF BC - allow custom error msgs for common exceptions (e.g. DML) ). Works just dandy.

Percentage calculation in t-sql based on two columns

Hi All
I have a source table with 4 columns and data like this..
ID Cnt   Col1   Col2
1    22    17      5
2    20    15      5
3    12    5       7
4    10    null    10
5    25    25      null
My output should look like this..
ID Cnt    Col1   Col2 Col1%   Col22%
1    22    17        5      77.27    22.73
2    20    15      5     75.00    25.00
3    12    5       7      41.66    58.34
4    10              10     0         100
5    25    25               100       0
Create Statement:
CREATE TABLE [dbo].[Sample] (
[ID] Int NOT NULL,
[Cnt] Int NULL,
[Col1] Int NULL,
[Col2] Int NULL,
CONSTRAINT [Sample] PRIMARY KEY CLUSTERED
[ID] ASC
Insert Statement:
insert into Sample(ID, cnt,Col1, col2) values (1 ,   22 , 17   ,   5 )
insert into Sample(ID, cnt,Col1, col2) values (2 , 20 , 15    , 5   )
insert into Sample(ID, cnt,Col1, col2) values (3 ,   12 , 5    ,   7 )
insert into Sample(ID, cnt,Col1, col2) values (4 ,   10 , null ,   10 )
insert into Sample(ID, cnt,Col1, col2) values (5 ,   25 ,   25   ,   null)
Right now I am using below SQL but % fields are not coming correct.
Select (COUNT(CASE WHEN (col1-col2)) < 1) THEN -1 END) /COUNT(*) * 100) AS Col1%
,(COUNT(CASE WHEN (col1-col2) >=1) THEN 1 END) /COUNT(*) * 100) AS Col2%
I need SQL to get correct values in col1% and col2%
Thanks,
RH
sql

Is it what you need:
SELECT Id
,cnt
,col1
,col2
,CASE
WHEN Col1 IS NULL
OR Col1 = 0
THEN 0
ELSE CAST((col1 * 100.0) / cnt AS DECIMAL(10, 2))
END AS [Col1%]
,CASE
WHEN Col2 IS NULL
OR Col2 = 0
THEN 0
ELSE CAST((col2 * 100.0) / cnt AS DECIMAL(10, 2))
END AS [Col2%]
FROM Sample

How to split rows based on two columns..

Hi all...
I have a requirement.
I have product column, sell, purchace prices..(total of three columns) in a data set.
my data set is such a way that..if sale price exists...there is no purchase price and vice versa..
I need too present in a report ,two tables:
table 1 consists of only Sale price items
table 2 should contain only Pruchase Items.
Please see the below picture for clear understanding..
Is that doable? Where do we need to impose a condition?I tried to impose a condition but,it didnt seem to work
http://i51.tinypic.com/29xfdc6.jpg
Please help.

Can you send me the template and xml file to [email protected]? I can try to help.
Did you try to filter out the records by the sale price or purchase price column not equal to null?
Thanks,
