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?
update table tab_name
set date_time =date||time
where your_condition

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..

Select or update a field based on a column on another row

hi
I have some 5000 rows for the following combination of columns. Each combination has two rows. The only difference between these two rows is an indicator field. If one row for the same combination is having indicator as 'M' the other row for the same combination should ideally have indicator 'R'. But unfortunately the other row's indicator is null.
ie. if the first row for same combination of fields, indicator is 'M. then other one is null which should have been 'R'. If the first row is 'R' then other one is again null which should have been 'M'.
PRODUCT_NO STATE MONTH INDICATOR
1001 CA SEPT M
1001 CA SEPT null
1002 NY OCT R
1002 NY OCT null
Here for the first combination indicator is M and other one is null. But i need to update it to 'R' since other rows is M.
Same way for second combination first row is R second row then should have M as indicator.
Basically it is changing field to a value based on the value in the other rows indicator for the same combination of the above columns.
Please help if anybody has idea to do this in simple steps
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 *
from @T

Multiple values from same column in diffetent columns in same row??

Hi all,
I am wondering how you can display different values from the same column into different columns on same row. For example using a CASE statement I can:
CASE WHEN CODE IN ('1', '3') THEN COUNT( ID) END as "Y"
CASE WHEN CODE NOT IN ('1', 'M') THEN COUNT( ID) END as "N"
Yes this will produce two columns needed but will also produce two separate records and null values for the empty's.
Any ideas?
Thanks

It's not clear what you want.

Deleting duplicate rows based on three columns in Oracle 8i

Hi all,
The database we use is Oracle 8i.
The query below raises the too_many_rows exception when I launch an application. So I want to delete the duplicated rows :
select polarisation_1, polarisation_2
into v_pol1_tech, v_pol2_tech
from v_cfh_lien_element
where nom_lien = p_nom_lien
AND num_canal_1 = p_num_canal_1
AND freq_emise_1 = p_freq_emise_1;
Notice that with many possible values of the parameters p_nom_lien, p_num_canal_1 and p_freq_emise_1 then the exception is raised.
So how to delete generally the duplicated rows based on the three columns "nom_lien" , "num_canal_1" and "freq_emise_1" ?
Thank you very much indeed.

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?

Color report rows based on a value in that row

I would like to Color report rows based on a value in that row.
For examplle with the "EMP" table:
I would like job=MANAGER to be red and job=CLERK to be green etc etc
The other example I found only had the option of one color either the highlight or the default color.
I am looking for a way to do multiple colors.

Hi,
In the row template, you can use #1#, #2#, etc to indicate where a field in the report needs to be output. This does not have to be plain text - ie, you can use it within style tags if you like.
So, take a query like:
SELECT EMPNO,
ENAME,
DEPTNO,
DECODE(DEPTNO, 10, 'green', 20, 'red', 30, 'cyan', 'white') BG_COLOUR
FROM EMPYou get columns 1=empno, 2=ename, 3=deptno and 4=bg_colour. In the row template, you can then do:
Before Rows setting (sets up the table):
<table>
<tr><td>ID</td><td>Name</td><td>Dept</td></tr>After Rows setting (closes the table):
</table>Row Template 1 (used for ALL rows):
<tr style="background-color:#4#;"><td>#1#</td><td>#2#</td><td>#3#</td></tr>Then, for every row, the colour that has been calculated using the DECODE function will be used in the style tag to colour the background for the entire row.
How you determine the colours is up to you. I've used DECODE here, but you could use a field on the DEPT table to hold this and use this in your SQL statement.

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.

Multiplication of two columns in a row

Hi All,
I have created an advanced table. In this table i am having 'price' and 'quantity' columns. i want to multiply these two columns and display result in 'amount' column in the same row.
Please let me know how can i approach this..
Regards,
Murali

Hi,
Since Quantity , Price are entered at run time the third column Amount can be calculated only when the request to the server is made.
Now enable PPR on the Price column , You can do this by setting the property ClientAction Action Type : FirePartialAction in the property inspector of the jdeveloper.
Also give the event name as AmountUpdate.
Then in the processFormRequest stage of the controller, check for the event AmountUpdate.If it is then get a handle to the row reference using pageContext.getParameter(EVENT_SOURCE_ROW_REFERENCE).This will give a key that can be used to retrieve the row access.Now find this row from the ViewObject.
Get the Quantity and price using row.getAttribute(ViewAttribute coresponding to Quantity ) .
Set the VO attribute related to the Amount .
So when the user tabs out of price field the amount field will be popluated thorugh PPR.

How to retrieving latest row based on a column value

Hi,
Lets consider a scenario. I have a table which has a order number, count column which is our fact, a type column which contains types e.g. (A,B) with A has more priority then B. Now in our graph we are getting all rows i.e. if we have two rows in db for order #1 one for type A and one for type B, then it shows us data from both rows in graph.
But I need only to show one row of type A in this case as A has higher priority than B. The row with type B should not contribute in construction of my graph if type A for same row also exists.
I tried a solution, for which i created a new column at logical level which contain 1 for A and 0 for B. Now i put Max aggregation rule in it to get maximum value which will be row with Type A in our case. But it did not work.
How we will can achieve it in OBIEE?
Thanks.
Aasim Khan.

Hi Steve,
I have a similar requirement... one of the columns in my table is a calculated value based on several xml fields,
<?xdofx:(MATH01+MATH02+MATH03+MATH04+MATH05+AA+AA1)+((FNDCD01+FNDCD02+FNDCD03+FNDCD04+FNDCD05+MCHCD01+MCHCD02) div '8')?>
if the resultant value above is less than 62, i do no want to display this entire row in the output. could you help me wout with this?
thanks

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)

Delete duplicate rows -- based on 4 columns -- how?

I asked this question on how to delete duplicates recently and received this suggestion which works well -- except --
With CTE AS
SELECT *, ROW_NUMBER() OVER (Partition by fld1 order by fld1) RowNum
FROM #tmpA
DELETE From CTE
WHERE RowNum > 1
-- the actual table I need to delete duplicate rows on is based on 4 columns. The following table contains 14,462 rows of which 14,348 are distinct -- based on the following 4 colums. Below is an image of a sample of the data contained in the
table for my question and to the right of that data is the column structures (data types). Is it possible to do something like the above example suggestion with the table in the image below? How to do that? I need to delete rows so that 14462
goes down to 14348. If I only reference one column for the delete -- this would delete like 7000+ rows. I only need to remove 114 rows.

Add the other 3 columns to the partition.
