PL/SQL :: How To Calculate Values And Display To Virtual Column
Mar 12, 2013
How I can build a query with conditions and calculations? E.g. I've got this table
Start | End | Working Place | Mandatory
------------------------------------------------------------------------------------
01-JAN-13 | 11-JAN-13 | Office | 1
14-JAN-13 | 25-JAN-13 | Home Office | 0
04-MRZ-13| 15-MRZ-13 | Office | 0
11-FEB-13 | 22-FEB-13 | Office | 1
Now if column working place=Office and column mandatory=0
the new column "price" has to calculate: (End-Start)* $25.00
and if working place=Office and column mandatory=1
the "price" column has to calculate: (End-Start)* $20.60
else $0.00
I tried it with the case statement but I didn't know how to calculate my values and display it to the virtual column "price".
Something like
case
when Working_Place = 'Office' and Mandatory=1
then ...
else '0.00'
end as PRICE
?????
Or is it not possible?

I'm using the Oracle Emp,Dept tables as my sample. I want to display certain table column values based on some criteria. If met, display those values otherwise display other column values
For example:
So when dept.deptno=10, I want to display these 2 columns values
1. dept.deptno
2. dept.dname
otherwise, display these 2 columns values
1. dept.loc
2. null
Can this be done with one case, decode or "other" type of structure going thru the table one time??
SELECT emp.empno,
emp.ename,
CASE
WHEN dept.deptno = 10 THEN
to_char(dept.deptno)
[code].......

------------------------------
ID DEPT CRS
------------------------------
1 CS CS_100
2 SCIENCE SCI_150
3 MATH MATH_400
4 HISTORY HIS_110
[Code]...
To display CRS from TABLE_A where DEPT = 'MATH' but in the following format.,
--------------------------------------------
NO DEPT CRS
--------------------------------------------
1 MATH MATH_400, MATH_550, MATH_230
--------------------------------------------
instead of.,

I have table with the values as below.
C1C2C3C4
NAMEJOHN10ABC
NAMESMITH30DEF
NAMEROBERT60XYZ
I dont want to print the repeated value(NAME) of C1 multiple times as below.
C1C2C3C4
NAMEJOHN10ABC
SMITH30DEF
ROBERT60XYZ
I could do it using the below query using union with the rownum.
select * from (
select rownum rn, c1,c2,c3,c4 from table_new
) where rn =1
union
select * from (
select rownum rn, decode(c1,null,null),c2,c3,c4 from table_new
) where rn between 2 and 3
Is there any other way of displaying using a single sql query.

what my issue is with this virtual column
CREATE TABLE C0HARPA.VCOL_TAB
(
col1 VARCHAR2(30 BYTE),
v_col1 VARCHAR2(6) GENERATED ALWAYS AS (SUBSTR(col1,1,6)) VIRTUAL
)
TABLESPACE TOOLS
[code]...
Lastly, can an index be created on a virtual column? I am thinking no since it calculated?

I am having issue with IMPDP on ORACLE VIRTUAL COLUMNS.I am having following table with Virtual column defined with Not null. Expdp is fine without any issue.
DDL :
------
CREATE TABLE alert_hist
(
alertky INTEGER NOT NULL,
alertcreatedttm TIMESTAMP(6) DEFAULT systimestamp NOT NULL,
alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL NOT NULL
When I do the import (IMPDP) it got failed with the following error.
. . imported "TESTSCHEMA"."VALART" 359.1 KB 4536 rows
ORA-31693: Table data object "TESTSCHEMA"."ALERT_HIST" failed to load/unload and is being skipped due to error:
ORA-39097: Data Pump job encountered unexpected error -1
After that I dropped the Virtual Not null column and recreated that column with Nullable.
DDL :
-----
alter table alert_hist drop column alertcreatedt;
alter table alert_hist add alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL;
After that I took the expdp and impdp , it went fine with out any issue.

Correct example
select
pp.IVA
, pp.CNR
, pp.POLO
,(pp.CNR-pp.POLO) diff
, ((pp.CNR-pp.POLO) * pp.IVA / 100) + (pp.CNR-pp.POLO) diva
from AB_PERIODI_PREZZI pp
Invalid example
select
pp.IVA
, pp.CNR
, pp.POLO
,(pp.CNR-pp.POLO) diff
, ((diff * pp.IVA / 100) + diff) diva
from AB_PERIODI_PREZZI pp
In my real view, the diff calculate column is very long (with case etc...) I must reuse many time the diff calculate column to calculate other columns.I do not want use subquery because there is many join to do in the same query. How can I reuse a calculate column in the same view?

when trying to calculate the occupied space for a table, I'm using DBA_SEGMENTS, which works fine as long as the table does not have a BLOB column.
As far as I can tell, the size of the BLOB data is stored with the SEGMENT_TYPE = 'LOBSEGMENT', but I cannot find a view that tells me which DBA_SEGMENT row belongs to the BLOB column in the table I'm checking.
To give you an example:
select sum(BYTES)
from DBA_SEGMENTS
where owner = user
and segment_name = 'MY_TABLE'
group by SEGMENT_NAME
returns 262144
running:
SELECT sum(length(blob_column))
FROM my_table
returns 821333
There are entries in DBA_SEGMENTS for my user with the type LOBSEGMENT, but I cannot find a way to map the correct DBA_SEGMENTS row to the table I am checking.
I'm using Oracle 10.2.0.3.0 on Redhat

I am trying to calculating the total column based on two columns, Total=unitprice*no.of items
I wrote this Javascript in page properties>javascrpt>Execute when Page Loads
"$('input[name=f05],input[name=f06]').change( function(){
parent_row = $(this).parents('tr:first');
sal = ( parent_row.find('input[name=f05]').val() == ' ') ? 0 : parseFloat(parent_row.find('input[name=f05]').val() );
comm = ( parent_row.find('input[name=f06]').val() == ' ') ? 0 : parseFloat(parent_row.find('input[name=f06]').val() );
total = sal * comm;
parent_row.find('input[name=f07]').val(total);
});
But its not Giving any result in total column?

My scenario is to insert values into 'out' column by comparing 's' and 'IP' columns of temp table.The exact situation is at first need to go to ip column,take a value and then go to source column and check for the same value of ip which is taken previously.Then after corresponding ip of that source column should be inserted back in previous source column.
The situation is marked clearly in file which i am attaching with '--' comments at respective places.I am also pasting the code which i tried out,unfortunately it is giving error as exact fetch returns more than requested number of rows since there are duplicates in the table.I tried it using nested for loops.Also implemented using rowid,but it didnt work.
fixing the errors or if there is any new logic that can be implemented.
DECLARE
i_e NUMBER(10);
BEGIN
FOR cur_1 IN(SELECT IP from temp where IP IS NOT NULL)
LOOP
FOR cur_2 IN(SELECT IP from temp where s=cur_1.IP)
[Code]...

On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.

I want to pass multiple column values of a row in an interactive report page to hidden items in another page through column link. And I did it successfully. However, I found I need to pass more than 3 columns of a row in this report, while a column link only permits me to pass 3 column value at most. Is there anyway that I can pass more column values to hidden items in another page?

I would like to have a table in HTML region and to display in the table some Page Items from the page.
I got the code like this:
{
<table>
<tr><td>&P1_ECEMEA_ASSISTANCE</td></tr>
<tr><td>&P1_ECEMEA_WIP</td></tr>
</table>
}
It shows the Page Item names as text, not the values. However this code without the table tags:
{
ECEMEA Request for CQT Assistance: &P1_ECEMEA_ASSISTANCE.
ECEMEA CQT Work in Progress: &P1_ECEMEA_WIP.
}
works and the Page Item values are displayed.
Is it possible to display the Page Item values in the HTML table at all or I have to use a different method of showing the values in a table? The above is only a snippet of the code. I need to display about 30 Page Items, formatted in a table with headings.
what kind of region is the best to be used or if I should only use some escape symbols in the table code.

PID SUM(QTY)

1 5
2 12
3 29
4 10
5 5
6 6
7 10
and it seems to work fine. But I now I want to display another column in the table called 'pname' which is a primary key in another table 'p'. 'spj.pid' is the foreign key.
2. Another query I can't perform needs the table s
