How to select record in mulitple rows based on another field's values?
Hi,
sorry about the bad title, really not sure how to explain this
Have the following data:
Cost_center Activity_type
1005009401 CLBR0
1005009401 CLBR1
1005009401 TLBR0
1005009401 TLBR1
1005009401 VEH00
1005009402 CLBR3
1005009402 CLBR4
1005009402 TLBR5
1005009402 TLBR6
1005009402 VEH07
1005009901 CE000
1005009901 CLBR0
1005009901 CLBR1
1005009901 TLBR0
1005009901 TLBR1
1005009901 VEH01 I need to return a list of cost centers (with its associated activity types) that do not have activity types of CLBR0 and CLBR1 and TLBR0 and TLBR1 and VEH01. So in the above data, cost center 1005009401 and 1005009402 would be returned.
Any thoughts?
Thanks.

How to select records from Interactive Reports based on checkboxes
Referring to the link below
http://apex.oracle.com/pls/otn/f?p=31517:95
I want to select rows from the Interactve Report based on a checkbox. This demo page has 2 sections, one for classic report and other for interactive one. The classic report is able to select the whole records but the interactive report selects only the emp nos. I am looking for a functionality where I can select the whole record from the interactive report.
Any pointers will be helpful.
ThanksThat is easy. You should just modify the query:
DECLARE
v_count INTEGER := 0;
BEGIN
:p95_text_ir := NULL;
FOR i IN 1 .. apex_application.g_f20.COUNT
LOOP
v_count := v_count + 1;
FOR c IN (SELECT ename, job, mgr, sal, deptno
FROM emp
WHERE empno = apex_application.g_f20 (i))
LOOP
:p95_text_ir :=
:p95_text_ir
|| 'ID: '
|| c.empno
|| ' / '
|| 'Name: '
|| c.ename
|| ' / '
|| 'Job: '
|| c.job
|| ' / '
|| 'Manager: '
|| c.mgr
|| ' / '
|| 'Salary: '
|| c.sal
|| ' / '
|| 'Department: '
|| c.deptno
|| CHR (10);
END LOOP;
END LOOP;
:p95_text_ir := :p95_text_ir || ' / Records selected: ' || v_count;

Formula to Display Value Based on Another Field's Value
Hello,
I have a column that displays the vehicle used for drives, but the report also lists fixed sites that do not have a vehicle assigned.
What I'm trying to accomplish is to utilize a formula but I'm having trouble with getting it to work. What I've got is:
if {CenterDetail.CenterType}=0 then {MobileSetupMaster.ShortDesc}
else
I'm not sure what to place in the else statement to make the value equal to null.
Suggestions?hi Trey,
are you just trying to show an empty formula or an actual null.
if empty, then
if {CenterDetail.CenterType}=0 then {MobileSetupMaster.ShortDesc}
else ""
will work. -
Choose field from joined table based on another field?
Good morning!
Is it possible to select a field from a joined table row based on another field? Consider the following data in the CVALUES table:
ID C1 C2 C3 C4 C5 C6
T1 9.6 10.3 12.4 19.6 19.6 0
T7 9.6 10.4 0 0 0 0
T3 8.2 9.9 11.4 19.6 19.6 0
T8 8.3 10.7 13.5 20.7 0 0
T5 9.4 10.3 12.7 22.9 19.6 0
...And the following data in the MDETAIL table:
ID MDATE CNUM ...
T1 03/28/2012 18:00:00 4
T1 03/28/2012 18:00:00 1
T8 03/29/2012 06:00:00 6
T8 03/29/2012 06:00:00 5
...I want to get the column from CVALUES corresponding to the CNUM field in the MDETAIL table. I'm currently doing this:
SELECT m.t1, m.mdate,
CASE WHEN m.cnum = 1 THEN c.c1
WHEN m.cnum = 2 THEN c.c2
WHEN m.cnum = 3 THEN c.c3
WHEN m.cnum = 4 THEN c.c4
WHEN m.cnum = 5 THEN c.c5
WHEN m.cnum = 6 THEN c.c6 END AS cvalue
FROM mdetail m
JOIN cvalues c ON m.id = c.idThe records in the CVALUES table are unique; only one row per ID.
This method works, and it's fast but it's messy code and I think there has to be a better way to do it. I use the cvalue value in several calculations so every calculation I use it in has this giant glob of CASE in it!Since you're comparing the same column against scalar values, the CASE statement could be simplified in a similar way :
CASE m.cnum
WHEN 1 THEN c.c1
WHEN 2 THEN c.c2
WHEN 3 THEN c.c3
WHEN 4 THEN c.c4
WHEN 5 THEN c.c5
WHEN 6 THEN c.c6
END AS cvalueSince performance is not the issue here, now it depends on what you consider "more readable".
Using a one-liner piece of code certainly makes the query looks less bulky, but I won't be so sure about readability and immediate understanding. -

</HTML>Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks, -
How to select data from a table using a date field in the where condition?
How to select data from a table using a date field in the where condition?
For eg:
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = '31129999'.
thanks.Hi Ramesh,
Specify the date format as YYYYMMDD in where condition.
Dates are internally stored in SAP as YYYYMMDD only.
Change your date format in WHERE condition as follows.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = <b>'99991231'.</b>
I doubt check your data base table EQUK on this date for the existince of data.
Otherwise, just change the conidition on BDATU like below to see all entries prior to this date.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and <b> bdatu <= '99991231'.</b>

Making a DFF field mandatory based on another field
Hello All,
We have a requirement where in we need to make a DFF field mandatory based on another field.
example:
DFF has two fields :
Filed1 : values 'Email', 'Fax'
Filed2
If 'Email' is selected in 'Field1' then Field2 should become mandatory.
Any inputs on this will be really helpful.
Thanks & Regards,
Satya.hi kumar3a,
recently, i spent considerable amount of time wracking my brain on a similar problem. the nearest i came to a solution was when i used a forms personalisation. mind you, forms personalisation will not work directly on the DFF window, so it has to be approached in a roundabout sort of way.
i got this information from an Oracle Support personnel - MOS Note 1078348.1.
i would start with the flexfield segment as "not required", and then using Forms Personalization, i would make it "required". i would try to figure out how to establish a condition where the previous 'required' flexfield segment's value is checked to see if this 'not required' segment needs to be made 'required'. in theory, this should solve the issue. i gave up on it because the forms personalisation would need to cover WHEN-VALIDATE trigger event, and we had close to 100 validations going on through other preexisting forms personalisations, which rendered it near impossible to employ this method.
best regards. -
Changing a field based on another field
hi one and all
i am looking for a way to change a field based on another field. if i have item 2 and item 8 on the page and item 8 needs to be required based on item 2 based on a requirement, how would this be done.
ex if item 2 has a PO inputed, when it is moved off the field, item 8 should be changed from required false to required true. i have tried in both the process request and process form request with no luck
any suggestions.
thankshello again
after your input and after reviewing the tutorial ( which i accomplished based on data from a table but not a field ) , i did the following and have been fighting it for a day. am i doing this correctly
on the itemid OrgRptCode1 i changed the action type to firePartialAction and the event is name o1
then i added this code to see if the action would fire
if (pageContext.getParameter("OrgRptCode1") !=null) // either line will be commented out
if (pageContext.getParameter("o1") !=null) // either line will be commented out
System.out.println("Field is not empty");
else
System.out.println("Field is empty");
am i missing a step . also
when i enter the page i get Field is empty. when i enter the field and tab off i get the error page w/ this msg

Table Control: make a field editable or not based on another field value
HI All,
How to make a column field input enabled or disabled based on another field value in a Table Control.
Here's the scenario:
I have a table control with two columns, KTOKK and LIFNR. Now for certain KTOKK, the LIFNR field should be editable and for certain KTOKK it should not be editable.
Eg., KTOKK = 0001 => LIFNR field is not editable.
KTOKK = ZKTO => LIFNR field is editable.
But these fields are in a table control.
Please advice.
Thanks in advance,

The requirement is like that I have a table with 6 fields (1 primary key and other are nonkeys). If the user inputs some values in the fields on the screen, then a row will be added in the table. Upto this i have done well. but when the user want to change some value in the existing row of the table my program unable to do so. Because I couldn't get any logic to do that as there are 5 nonkey fields, so if any one field is modified then the respective row should be selected first based on the user selection and then it should be updated.
At this point I could not get any idea as it may take a lots of if conditions (I guess) to reach to that particular row.
Please help..
thanks ,
sekharHi Sekhar,
I am afraid, the whole design of your program is wrong, let me explain
Let us say you have two rows(5 non key fields) that the user wants to update and the data in these five non key fields are identical and in your program you are getting a number(which is the key) using a number range object. So you will have two entries in the table for the same data.
And on the update page when the user enters the non key fields, how will the program know(or for that matter any one of us) which record to pick, if you have two identical books and if asked for a book wouldn't you ask which one among these two do you want?
Possible Solution: Identify a possible key maintaining the integrity of the data, that is a combination of the non key fields which will help you identify a unique row and make these fields as key fields in the table.
A more costly solution(if you do not want to change the non key field keys to key fields) would be to, adding a check(using select statement) to see if the non key fields combination already exists in the Z table before inserting a record into the table.
If yes, throw a message to the user and just update the values in the table, else insert the record.
Another solution would be to, use the non key fields to generate a key(using some logic) and using this instead of the number range object.

Chen
