Write multi-records

Hi Experts,
I found very good how-to guide in SDN to read multi records with cobol copybook.
And I would like to write multi records txt file? Every line has different length but fixed. I can have repetitif line like contact because vendor can have several contact but all contacts have the same fixed length.
Exemple Vendor
Vendor:<Name><Type>...
Address:<Address>...
Contact:<Fix Telephone>..
Contact:<Moble Telephone>...
Vendor:<Name><Type>...
Address:<Address>...
Contact:<Fix Telephone>..
Vendor:<Name><Type>...
Address:<Address>...
Contact:<Fix Telephone>..
Contact:<Moble Telephone>...
Thanxs,
Nl

Reading yes, writing no.
There are workarounds, e.g. write one file with all header rows, another with all detail rows and both files have the header plus a number in the first two fields, e.g.
HEADER
ORDER;1;data
00001;1;abc
00002;1;def
00003;1;ghi
DETAIL
ORDER;2;LINE;data
00001;2;0001;xyz
00001;2;0002;sge
00001;2;0003;dff
00002;2;0001;rfew
When you then take both files, merge them together and sort them you get them interleaved
00001;1;abc
00001;2;0001;xyz
00001;2;0002;sge
00001;2;0003;dff
00002;1;def
00002;2;0001;rfew
00003;1;ghi
This is just one approach, other work similar. The only multi-record format DS can write out of the box is XML.

How to do it in multi-record block

Hi all,
i have 1 text items in a multi-record block number of record displayed 10
and i have values like 100 , 50, 30 in first 3 records and in 5th record i want to put some value like
20 then i want to calculate all values like 100 + 50 + 30 +20 = 200 and i want to put the total value in a single record block.
but my problem is i cannot able to calculate all the value because for the totale value i have to
write a for loop to loop through the record
but go_block() is not working in post_change .
if any solution is there plz suggest.......

Hi zeeshan
my problem is i cannot able to calculate all the value because for the total value
put the total value in a single record block.
First pls the following...
Guidelines for Working with Calculated Items Calculated items_
1- They are display-only control items.
2-Calculated items cannot be database items.
3.While you can set a calculated item's Enabled, Mouse Navigate, and Keyboard Navigable properties to Yes,
you cannot set the Insert Allowed or Update Allowed properties to Yes
Second Keyword: TOTAL is a reserved oracle key word... pls read the Details...
go_block() is not working in post_change .well u can use timers but no need for it u can reference block item but first u have to accumulate the values per record in WHEN-VALIDATE-ITEM TRIGGER in the last calculated item which is inserted by the user and assign it to the display item in ur current multi-record block :*block_name.total_item*.. as follow...
:block_name.total_item := :item1 + .... ; Then u create a second display item > no of records property = 1 , named e.g. final_summarized_totals
In order to summarize this total values accumulated in the multi-record display item named e.g. block_name.total_item
Finally using PRE-INSERT , PRE-UPDATE,PRE-DELETE Triggers to assign the value calculated into the display item * block_name.total_item* into the db_item into the previously mentioned Trigger Block-Level Off-course.
:block_name.total_db_tem := :i:block_name.final_summarized_totals ; Hope this helps...

How to call a report with a bind variable from a multi-record block

Hi,
I have created a report using the BI Publisher functionality. I did all the integration, created the SQL Query and uploaded the template. Up till here everythings fine!
My SQL Query has 2 bind variables.
I will call my report from a multi record block, at the end of each record an icon is shown which the user can click to open the report.
I created a column link for this item (PRINT_REPORT=Inschrijvingsformulier) but I do not manage to pass the parameters to my report. The parameters I want to pass are 2 columns in this Multi Record block.
I created 2 hidden fields on the page P9_PARAMETER1, P9_PARAMETER2 with the same names as my bind variables and fill this in with the values #PARAMETER1#, #PARAMETER2# from the multi record block.
It seems it does not work as my report stays empty. (also XML file stays empty).
Am I trying the wrong way?
Thanks for any advice,
Kris

hi khadeer,
create one report program and write the required code,and call this function module 'SSF_FUNCTION_MODULE_NAME' and give your smartform name and also when u activate ur smart form u will get one function module call that function module also and specify any tables used...
i think this solves ur problem...
any queries revert back..
pls reward points if helpful,

Querying wide (multi-record case) table data in oracle 10g

I've got a set of "wide" (multi-record case data format) tables similar to the format described in Oracle's "Oracle Data Mining Concepts" book in chapter 2 (http://download-west.oracle.com/docs/cd/B14117_01/datamine.101/b10698/2data.htm#1010394).
I like the flexibility of this format, especially since it can handle thousands of attributes. But the main problem I have with this format is in determining how to write efficient, complex queries against the data.
I've included some sample data below to demonstrate my problem. I've got two tables, one with people and the other with the attributes and values of age, income, height and weight. If I try to generate a complex query against this data, I seem to either have to rely on multisets and functions, or on a large number of self joins. Neither of which seems to scale well or perform well for large amounts of data. I know I could also add a pipelined TABLE function to filter the data more, but none of these options seem like great solutions. Does anyone have any ideas for a better way to form complex well performing queries against this type of data layout?
For example, with my sample data below I'd like to select everyone whose (income = 2000) or (income = 50000 and weight = 210), but the only way I see of doing this is with a query like the following (which won't take advantage of any indexes on the data):
select * from people_attributes_view
where find_eq_attr(AttributeValue('income',2000),attribute_values) is not null
or (find_eq_attr(AttributeValue('income',50000),attribute_values) is not null
and
find_eq_attr(AttributeValue('weight',210),attribute_values) is not null);
Any help is greatly appreciated.
Thanks.
-- My full example starts here ----------------
-- Create the sample tables and data
create table people (id int, name varchar(30));
create table attributes (id int, attribute varchar(10), value NUMBER);
insert into people values (1,'tom');
insert into people values (2,'jerry');
insert into people values (3,'spike');
commit;
insert into attributes values (1,'age',23);
insert into attributes values (1,'income',1000);
insert into attributes values (1,'height',5);
insert into attributes values (1,'weight',120);
insert into attributes values (2,'age',20);
insert into attributes values (2,'income',2000);
insert into attributes values (3,'age',30);
insert into attributes values (3,'income',50000);
insert into attributes values (3,'weight',210);
commit;
-- Create some types, functions and views for the search
CREATE OR REPLACE TYPE AttributeValue AS OBJECT
(attribute varchar(30),
value NUMBER);
CREATE OR REPLACE TYPE AttributeValues AS TABLE OF AttributeValue;
create or replace function find_eq_attr (val AttributeValue, vals AttributeValues) RETURN AttributeValue IS
begin
for i in vals.FIRST .. vals.LAST
LOOP
if ((val.attribute = vals(i).attribute) and
(val.value = vals(i).value)) then
return vals(i);
end if;
END LOOP;
return null;
end;
create or replace view people_attributes_view as
select p.name, p.id,
cast(multiset(select attribute,value from attributes a where a.id = p.id)
as AttributeValues) attribute_values
from people p;
-- Search for everyone whose (income = 2000) or (income = 50000 and weight = 210)
select * from people_attributes_view
where find_eq_attr(AttributeValue('income',2000),attribute_values) is not null
or (find_eq_attr(AttributeValue('income',50000),attribute_values) is not null
and
find_eq_attr(AttributeValue('weight',210),attribute_values) is not null);

I like the flexibility of this format, especially
since it can handle thousands of attributes. But the
main problem I have with this format is in
determining how to write efficient, complex queries
against the data. Can't be done. The flexibility is achieved at the cost of simplicity and performance, it is a trade off.

Writing waveforms from Ch. 0 of niSCOPE to binary file in a multi-record setup?

Hello,
I am not very experienced with niSCOPE and writing waveform records, so I need some expert help here.
Here is my application:
I am generating a pulse train using a 6602 counter/timer. Each rising edge of this pulse train triggers an niFGEN to generate a single sawtooth waveform output to another device and, at the same time, acquiring data from Ch. 0 of an niSCOPE. I am fetching one record per rising edge of the pulse train for the niSCOPE (multi-record setup).
The attached VI is where I am at thus far. All triggering and reading/fetching of the waveforms seems to be working just fine when testing with an oscilloscope. I now need to save each waveform record along with the timestamp of its rising edge trigger to a binary file. The bottom of the VI is where my attempt is at saving the waveforms to a binary file, so the attention should be there when looking at it.
I am running LabVIEW from a computer connected to the NI PXI-Chassis using a cross-over cable.
Questions:
1.) Do I need to convert the data coming in on Ch. 0 of the niSCOPE to digital? Does it come in as analog from an oscilloscope? If I need to do this, how can I accomplish this?
2.) When I try to run an example VI to write a waveform to a binary file by choosing "My Computer" in the bottom left of the VI window, it works it saves the file just fine. When I change this to run on "PXI2", a file is not even created and I get an error on File Dialog (code# 7, I think) each time the file is attempted to be closed. This may be a stupid question, but why can I not save data to a file on my computer if running the VI on "PXI2"?
3.) Assuming the saving of each waveform to a binary file is working (read: (2) is successfully addressed), how can I also write the timestamp of the starting trigger for the waveform along with the waveform in the binary file? An example VI of how I can accomplish this would be fantastic, but I haven't been able to find one thus far.
4.) When I was messing around and trying to accomplish this, it seemed that doing this writing may slow down the entire process too much. I need to record data to the extent of the sawtooth waveform generated by the niFGEN AWG for each trigger. Is there any changes I should make to my acquisition process in the niSCOPE section so that I can read each waveform, along with keeping the timestamp for each, and write this information to a binary file?
I need to get this working quickly, so any help on this is greatly appreciated. Thanks in advance.

Thank you so much for your reply, David. Let me try and explain my
situation and setup a little better, as well as discuss the points you
made in your reply. Beware, you may want to refill your coffee as this
post is long .
I am using an embedded controller in a PXI-1044 chassis. I now have the
chassis hooked up to our local network, and I am deploying my project
to the chassis over the network as I am also connected to the local
network. I have an oscilloscope next to me that takes as input the
pulse train for a trigger and the generated sawtooth from the niFGEN
for each trigger (rising edge of the pulse train from the 6602
counter). Just to make sure synchronization is taking place, the
sawtooth is also fed as input to the niSCOPE for acquisition.
"PXI2" is what shows up when I choose to run a VI on the PXI chassis
rather than "My Computer"; not sure why the 2 is there either, but that
is what it says. I may have tracked down the issue I was having with
writing, but more about that a little later...
The attached VI is an update, although not much has changed. My
application design is like this (keep in mind that some values for VI's
are still constants in the block diagram while others are controls on
the front panel): I am using the 6602 to generate a 1 KHz pulse train
and routing this pulse train to PXI_Trigger0/RTSI0. I am also using the
PXI_Clock (10) as a sample clock for this, and also using this same
clock as the reference clock for both the 5422 and the 5124 (as per the
synchronization help file mentioned for synchronizing multiple
devices). Both the 5422 and the 5124 are triggered by a digital rising
edge (from the pulse train) on PXI_Trigger0/RTSI0 (as it was routed
there). For each trigger, the niFGEN generates a sawtooth waveform
using a stepped trigger mode and outputs it. For each trigger, the
niSCOPE acquires data. They are both synchronous, which is tough to see
since one has its trigger source on the front panel and the other has
its trigger source on the block diagram. All devices use PXI_Clock so
they are synchronized.
The expected behavior is to only generate a single sawtooth waveform
per trigger with a certain number of sample points. I want to acquire
the same number of samples using the niSCOPE, which is what I meant by
"the extent of the waveform" in my previous post. So, should I change
the 8192 to 1000 for the number of samples for the niSCOPE? What would
you recommend for the sampling rate? I have been using 5 MHz for the
niFGEN and 5 MHz for the niSCOPE...this is how it should be done,
correct? If it is different in the VI, please let me know. For some
reason, I have to adjust all of the values each time I open it since
the default values are not the ones I want.
I want to generate and acquire one waveform per trigger (one waveform
per record). However, I want to be able to record a large number of
records so I have enabled the circular buffer-like treatment of the
acquired waveforms. The 100 or 1000 records is actually just a number I
am giving it for now to make sure it is working before recording many
more records.
As for saving the niSCOPE data, I would like to save all data in a
single file that is NOT ascii (to save space). I have been looking at
the HWS file format, and would like to use it. I think the attached VI
includes this at the bottom of the while loop. For each trigger, I
would like to save the time (as accurate as possible) that the trigger
occurred for the record/waveform, which appears to be (absoluteInitialX
- relativeInitialX) as you said in your post (thanks!). I just need to
store as much information about the waveform and time information for
it as possible with the waveform in the file. So it looks like I will
need to use the wfm info for that information, providing portions of it
as waveform attributes in the HWS VI's?
What format of data do you recommend I fetch, and will I be fetching a
"Single waveform" or "Multiple waveforms"? Should I use I32, DBL, WDT,
or other for the format? A balance between good precision in values and
time it takes to fetch/record would be best.
Given all of the above, I am having one troube with saving data to a
file. As a reminder, I am deploying the project to the chassis over the
network. When I choose a location and/or file to save the HWS data to,
I only get choices that are on the PC's hard disk (such as C:\Documents
and Settings\cgifford\...) NOT the chassis's hard disk. When I choose
something other than "C:\" I get an error that the file could not be
opened. However, when I choose "C:\" everything goes fine. The saved
data is nowhere to be found on my PC though, so I am assuming that it
is being stored on the internal 60G hard disk in the chassis that must
be named "C" by default or something!?
I have been told by phone support that I should be able to make a
direct connection with the chassis just like another PC, and should be
able to access the information on its internal hard disk in a drag and
drop fashion. I however cannot directly connect to the PXI chassis to
get the data that has been saved on the hard disk. We are running
Windows XP on the PC. We did some poking around and noticed that the
chassis is not running Windows file sharing, and only has ftp and http
running. We tried to access it using ftp, but we didn't have a username
and password to supply it. So, how can we enable Windows file sharing
on the chassis? How can I connect to it to do drag and drop to get
saved waveform data off of it? This is the main problem I am now
facing. Eventually we would like to store data to an external hard disk
connected to the chassis, which assumes that I can have access to the
internal storage to tell it to save files to the external hard disk.
For now saving it to the internal hard disk is just fine until
everything is proven to work, but I would like to get the data off of
the internal hard drive to put on another computer.
Any answers/suggestions on my above questions are greatly appreciated.
I also want to thank you for reading this long post . I eagerly await
a reply. Thanks again in advance.

Populate multi record display item

Hellou gurus!
I have forms 10g and i need to populate display item in enter query mode. My problem is that I have table T1 with some static values. Table T2 is through ID connected (reference) to table T1 1:1 cardinality and T2 table also have reference to T3 table.
I have block B2 based on table T2 and in this block I have multirecord item for inserting and updating new values for T2, but in this block ii also have no DB, multi record display item (because i don't want to allow editting in T1 table records) for diplaying static values for table T1. I want to display all static values from T1 next to the editable values in T2 (T2 multi record field is not insert yet). I tried for loop, select into but it not work. T1 values need to be selected before I started to inserting values into T2 items, but off course they need to be referenced It is hard to explain but i belive you understand.
Can you help me how I can populate multi record item??

You have to write the code again for your second list item....
group_id RecordGroup;
list_id Item := Find_Item('button.tyear');
list_id1 Item := Find_Item('button.tperiod');
status NUMBER;
rg_name varchar2(40) := 'recgroup';
BEGIN
----------------------------- LIST
clear_list(list_id);
group_id := Find_Group(rg_name);
IF NOT id_null(group_id) then
Delete_Group(group_id);
End if;
group_id := Create_Group_From_Query(rg_name,
'select vm_year, vm_year from fwqgl.vouchermaster
group by vm_year');
status := Populate_Group(rg_name);
Populate_List(list_id, group_id);
/* --------------------SECOND LIST ITEM...BUT REC. GRP NAME CAN BE SAME,better to use another name if you need to retrieve list and store qry..other wise the fol. code is enuf-----------------------*/
clear_list(list_id1);
group_id := Find_Group(rg_name);
IF NOT id_null(group_id) then
Delete_Group(group_id);
End if;
group_id := Create_Group_From_Query(rg_name,
'select vm_period, vm_period from fwqgl.vouchermaster
group by vm_period');

About populating a non-database item in a multi-records block

Hi, all
I have a problem about populating a non-database item in a
multi-records block. This block is set to database block with a
controlled item which needs to be populated after query. so I
create a post-query trigger, but my problem is when the records
listed in this block are less than 10 ( the record number is set
to 10), the trigger fires no problem. but when the retrieved
records are greater than 10, the error message is 'post query
trigger raised unhandled exception ora 01403'. anyone can help me
fix this problem?
Thanks in advance
Diana

Diana,
When you have an unbound item in a block and want to fetch
some data into it you need to write a post-query trigger.What
you have done is right.But it seems that u are getting a No data
found error.I am sure about how u r populating data into that
field.If u have written a select statement to fetch the data in
post-query trigger, kindly handle an exception and find out the
problem.Having a look at ur code(pos-query) would be much more
helpful for giving a better solution.Try this a let me know.
Thanks
Vinod.

Record level commit in a multi record block

Dear all,
i have a multi record block in my form (only one block)
after entring record the save buttons commites the form
if any error is raised then total commit processs stop for example if DUP_VAL_ON_INDEX is raised
what i want is that the form shoud act record level,i.e; it should commit record wise so that though a excepton is raised atleast record above that are commited.
thank U

mail : [email protected]

you can have non-database block and write "insert into <table>" statements for each row of block at when-button-pressed of 'commit' button. Commit after each row insertion. This will serve your purpose.

Duplicate item value in a Multi-Record Block

Is there a way to chek duplicate value entered in multi record block?
I have seen some solutions in this forum however nothing has worked for me till now. (using the formula, creating hidden items & creating group etc)
Thanks in advance,

To see if there are any other records in the block with the same value, use Kevin Clark's famous function to trap duplicates. You can find Kevin's function write up here:
Re: checking for same rows in a tabular
From Kevin's post:
Create a field PK_COPY in a control block.
Create program unit function COMPARE to compare two input params returning 1 if they match else 0.
Create a field in the datablock PK_MATCH, calculation property formula, formula COMPARE(:DATA_PK, :PK_COPY)
Create a field in the control block NO_OF_MATCHES, calculation property summary, summary type SUM, summarised
item PK_MATCH.
Also, your control block requires the Single Record property set to yes, and the base table block requires the Query All Records property set to yes.
WHEN-VALIDATE-ITEM on DATA_PK
:CONTROL.PK_COPY := :DATA_PK;
if :NO_OF_MATCHES > 1 then
message('You have already used that one');
Raise form_trigger_failure;
end if;

Multi-record / spread table...moveable fields in designer generated form

Good morning all;
I hope you are doing good...
Imagine a multi-record block layout with it's overflow property set to spread-table to accomodate 10 varchar2(25) fields. Now, of the hundreds of users working with this generated form, not one of them wants to see the fields in the same order on the screen.
What i would like to do is generate the form from designer so that a user could 'drag'n drop' let say, field #10 to the field #2 spot on the screen. Something like windows explorer where you can move the 'Size' column around so it is viewable without having to use the spread-table bar at the bottom of the screen...
Any idea on how to generate this form from designer?
Thank you and wish me luck!

I don't know a solution, but I think a solution could be easier found if it was a read-only block. You did not specify that. Then maybe you could dynamically change the query behind the block.
Good luck, Paul.

Updating a value of a text item in a multi record block based on a change

Hi,
I need to change the value of a text item in a multi record block based on a change to another item's value in the same block.
Suppose there's a text item in a multi record block called dt1 which is of type date, which is changed in a particular record. I want to change the values of the another item in the same multi record block, for all other records by running a loop through all the records in multi record block. I dont want to do it on the press of a button, it should do automatically on change. Help me resolve this issue.

How can I create a loop in a multi-record block (on the background)

I have a multi-record block.
In one item I change a value.
Upon this change, in the when-validate-item I would like to
change other records in the same block.
I planned to loop the block with go_record and to do my things
in each record. Unfortunately the go_record built-in is
restricted and cannot be used in a wvi-trigger.
Another approach can be to update the records in the database
and to perform an execute_query after this change. Also this
procedure cannot be used in a wvi.
How can I easily loop in a multi-record block???

You can try to put loop with go_record in KEY-NEXT-ITEM on that
field.
Or if you change something and then press KEY-COMMIT you can
update another records in database and after commit do again
execute_query. Something like :
on KEY-COMMIT:
update_another_records;
commit_form;
execute_query;

Get next value in a Multi Record Block

Hi,
I've a Multi Record block with 2 items like below.
pos width
1 7
8 5
13 5
18 2
ie pos in next item is sum of pos and width of previous item.I've already implemented this.
The problem is if the user changes width in a particular record,I want to change next records pos automatically.
To achieve this,I wrote a when-new-record -instance-trigger as follws:
if :system.cursor_record=1 then
:pos:=1;
elsif :system.record_status='changed' then
:pos:=:pos+:width;
end if;
but even Though I change column width of block,:system.record_status still remain 'INSERT'.
Pls can u pls tell me how can I acheive this?
Prashanth Deshmukh

You cannot use Record Status like that.
You need to create a procedure that loops through your entire block, keeping track of the pos and width of the prior record to calculate the new pos of each record.
Your procedure would need to do something like this:
Declare
    v_Pos pls_integer := 1;
Begin
Go_block('B1');
First_Record;
Loop
    Exit when :System.record_status='NEW';
    :B1.pos := v_Pos;
    v_Pos := v_Pos + :B1.width;
    Exit when :System.last_record = 'TRUE';
    Next_Record;
End Loop;
First_Record;
End;

How to do validation on multi record block at run time...

Dear Friends,
I have to do validation at run time on multi record block.
If user tries to enter and save two or more records in same multi record block with same data at run time, it should not allow it and display a message like, " error : Records are having same(duplicate) values. "
I already did validation with the data coming from database table using cursor. But confused about how to do at run time(on one screen only) ??
Please, give details about how to check duplicate records on form block before saving it to the table ????
Regarding details would be greatly helpful.
thanks,

Hi...Pankaj
thanx for your reply..
I already did validation for the data coming from table....
but I need to do it on form only...at run time...
exa...
In one multi record block
record no : column 1 : column 2 : column 3
1 abc 123 hi
2 abc 123 hi
so it should check on the form itself, here I m not getting data from table...I am just
navigating from first record to second using down arrow.
so, may be 2 possibilities.
1) when user navigates using tab to third record, it should say like two duplicate records.(may be like when validate record or item)
2) or when user tries to save, it should say two duplicate records.
so, everyting should take place on form screen only.....
waiting for your reply,
thanx...

Oracle Forms - need to update multi-record block - Help needed asap

Hi,
We are using Oracle apps release 11i - Oracle forms 6i.
I have a field "project_start_date" in project_block in a custom form. There is another multi-record block called role_block in the same custom form and it has a field named start_date. Requirement is when ever I make change in the project_start_date in project_block, that should reflect in role_block.start_date. I tried different means and could update only the very first record of the multi-record block - role_block. I need to update all the records in the role_block with the same project_start_date. Used looping and several other methods. But could not achieve. Any help is really appreciated.
Thanks
