Querying Multi-Record XML

Hi,
I have inserted the following XML document in to a table with an XMLType column:
<?xml version="1.0" encoding="UTF-8"?>
<PhotoImaging xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/xdb/photoImaging.xsd">
     <EmpData>
          <VRN>1111</VRN>
          <Surname>Shah</Surname>
          <Forename>Sunil</Forename>
          <PayNo>1234</PayNo>
          <WarrantNo>1234</WarrantNo>
          <ImageFile>c:\sunil.jpg</ImageFile>
          <ImageDate>12-12-04</ImageDate>
     </EmpData>
     <EmpData>
          <VRN>2222</VRN>
          <Surname>Malde</Surname>
          <Forename>Kalpa</Forename>
          <PayNo>5678</PayNo>
          <WarrantNo>5678</WarrantNo>
          <ImageFile>c:\kalpa.jpg</ImageFile>
          <ImageDate>12-12-05</ImageDate>
     </EmpData>
</PhotoImaging>
This is just a simple XML document with 2 records.
The problem I am having is when trying to query this document to retrieve, say, all the Surname's.
I can use:
select extractvalue(xml, 'PhotoImaging/EmpData/Surname') from mphr2_photo_xml
This works well if the XML document only contains one record, but in my case the XML document will contain hundreds of records and 'extractValue' can only return one value.
Does anyone know of a way to query this XML document and return all the Surname's??
Thanks, Sunil

It's OK. I got it from looking at some of the other threads.
For information the SQL is as follows:
select extractValue(value(q), '//Surname')
from mphr2_photo_xml,
table (xmlsequence(extract(xml, '/PhotoImaging/EmpData'))) q

Return amount of records after query multi-record block

Hello,
I would like to have a restriction in my multi-record form that counts the amount of returning records (after execute_query). If the amount is >= 1000 then I have to raise an error.
How can I implement this?
Best regards,
Ronny.

It most cases forms doesn't return all rows to the user in a batch unless the block property Query-all is set to yes. But if you have sum items based on that block, you have to set it to Yes. If you can turn this flag off and change the Query Array Size (block property) to 0 or something small (like 20), you dont have to worry about how many rows the query is going to return.
In you case, sounds like you want the user to put more constraints if rows returning > 1000 and you probably dont want the user to ever look those rows. You can do a
select count(*) from your_table
where --your critera
and rownum < 1001
before execute the query. But this select might take
a while if you table is very big in oracle 9i.
The easiest thing is to turn off the Query-All switch, let the forms handle the query and let the user decide whether to refine the query.

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.

Query about multi record block

Abdetu
Please clarify this
I have a multi record group on the canvas, which displays 5 records at a time. The block is based on a table. All the items, except 3 items are displayed items.Now in the block I have a list item, in which I have two values "PO" and "TSF".. If user selects PO, associated text items will get enabled and user will be entering the values .. Same is the case with TSF .. And at the end user selects Ok button to save the record to the database
Now while fetching the records (based on query) ..once the records are fetched, control will be on PO/TSF list box, now the user can either change PO to TSF or TSF to PO ..or he/she may opt not to change also.. If user changes PO to TSF, only that particular record's TSF fields should get enabled .. The problem what I am facing is, when the control comes to PO/TSF list box.. since its multi record block, all the record's PO/TSF list box are getting enabled
In the sense, if control is in the 1st record of multi record block, only those fields should get enabled, once the user navigates to the text item which is the last of that particular record, then 2nd record should get enabled....
Can I know the solution

Hello Seshu
ur case explanation should be in points 1,2,etc as possible leaving extra lines and spaces in between .. and the case should be more clear and summarized like:
1- I have multi-records data block.
2- I have a static list item with 2 values eg. (a and b).
3- Depending on selecting from the list some items r enabled.etc.
Kindly note that, this will facilitate ur problem to be more readable,recognizable and save time and effort of someone who wants to help u.
Here comes the confusion:
Now while fetching the records (based on query)
The problem what I am facing is, when the control comes to PO/TSF list box.. >since its multi record block, all the record's PO/TSF list box are getting enabled i think with the piece of code i have just posted to u this can't be happened since it disable all the record's PO/TSF.
if this didn't solve ur problem i suggest either u post ur code to help u or u try to put some validations with :
if statment inside the loop depending on the list item's values which will enable or disable related items to the list.
Hope this help u,
If any Questions pls let me know..

Abdetu..

Cursor Jumping to last record when query mode for Multi-record block.

I have a multi-record block. the seq field has this validation to check that there should not be a gap

Now as I want to update the records, and when I navigate across field(s_type,cer_dl,Seq,xyz) using tab and move the cursor down on second
record(IAS N 2 N), what happens is when I navigate to sequence field the cursor jumps to LAST RECORD( IAS Y 3 N ) of LAST field XYZ.
I am putting the sample record
s_type cer_dl seq xyz
IAS N 1 N
IAS N 2 N
IAS N 3 N
IAS N 4 N
IAS Y 1 N
IAS Y 2 N
IAS Y 3 N
The cursor moves to last record --IAS -Y -3-N when I tab across the second record.

When I say enter-query and put 'IAS' in the s_type field...For your validation to work you must not allow users to enter records in the middle of a block, clear records from the block or query specific records. If you allow the users to enter a query then you are allowing 2 of the rules to be broken.

How to re-query changed record in multi-row block after update in a called form

Hi,
I have a form that I use to perform searches, which is a multi-record block.
The user can navigate to a record, press a button on call another form which provides
more detail, and allows update of the record.
If the user changes it, and returns to the original search form, how can I re-query the
changed record to update the fields on the search form.
Is there a way other than to re-query the
whole block - a built-in to just update on record if it's changed on the database.
If not, can I use globals to pass back the data (since only a few fields are updatable),
and change the record without effecting its forms status.
Many thanks
Bernie

BD,
I haven't managed to look at a solution yet, but the block is a large multi-row block,
with an ORDER BY, and since it can return a large number of records, there is a short
delay. I was hoping there was a way of just
re-querying the one record, which was displayed
in the second form for update.
I'll give the query a go, or might try and pass back some globals with the update values.
By the way, DML Return Value is an excellent feature, but only works against Oracle 8.
It basiclly adds the RETURNING clause to any DML statement (see SQL manual), so that if
a trigger changes/adds values you didn't provide, it will return them back to you
so the values in your form are correct.
I use a trigger on the DB to populate history fields (create/update,who/when) and
the PK sequence. Using this feature, those values are returned to the block and displayed.
Regards
Bernie

Querying a multi-record block within my form

I have a form where I perform validations of items entered on my main block. I compare the item value entered to an expected value and if they are different then an exception record must be created in a separate, multi-record block within my application. One record on my main block may end up with multiple different exception records in the multi-record block. As a result, part of my validation must include determining whether the user has already created an exception record for the item that I'm validating in the multi-record block.
Is there a way for me to query and uncomitted, multi-record block in my form? Help would be greatly appreciated!

Andreas' method is good.
Only several changes:
LOOP... EXIT WHEN :SYSTEM.RECORD_STATUS='NEW';
(Use NEW, not TRUE)
And just before the Raise Form_Trigger_Failure, I would Go_Item to either the item in error, or to a new line in the exceptions block. And also issue an error message.
....By the way...
If your exceptions block has more rows than will fit on the screen, then your search loop function will may cause the rows to jump up or down when the user tries to commit. There is a way to reset the view after the function completes its search -- you just need to store the value of the block's Top_Record property before the First_Record command, and then Go_Record(Top_Rec_value); after the function completes its loop.
Also, there is a way to prompt the user to enter the exception record when you first validate the item in a when-validate-item trigger. But the user might ignore the prompt, so you still need to re-check everything from the key-commit process. To use the WVI prompting, in the WVI trigger you check if an exception is required. If it is, store the item name in a package variable, then start a non-repeating timer. When the timer expires, save the :System.cursor_item value (so you can go_item back to it after calling the function), and then call the function to check for the exception for the item named in the package variable. If not found, prompt the user. If found, go_item back to the cursor_item_value.

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,

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.

How do I take data from a query sample record and query another block with it?

I have a master/detail form (6i) that contains a master block (staff), and a detail block (phone). I would like to be able
to query by phone number, but when I execute the query, I would like a 'search results' box to pop up that contains the
phone number I queried for, as well as some other staff info. There might be multiple records that match my query,
and I'd like them all to be listed (or list 10 or so, with a scrollbar). I'd like a push button next to each record that will take
me back to the master/detail window with that record displayed. So, I created a third block that is based on a joined
view of the staff and phone tables. It is a multi-record block, with 10 recs displayed and a scrollbar. It is in a separate
window. I don't want the user to have to navigate to that block, however, to perform their query. I would like them to be
able to enter the query in the phone number block, then somehow grab the phone number they've entered and use it to
query my 'search' block. This is the part I'm having trouble with. Can someone please help? THANKS!

Where do I put that line of code? I see that it goes at the Script part near the top, but how can I use that, I am pretty new to this language. I am not familiar with this line, where does it bind the value from the datagrid to the variable?
fullXML[myDataGrid.selectedIndex].FIELD_NAME;
myDataGrid would be the id from the grid I am guessing?
and selected index would be the channel.description part?
and FIELD_NAME; is the variable name?
does this go into a funtion or is it placed at the top where the variables are declared?

Clear form not working in multi record form 10g.

I have a multi record block form, when sys_indicator is 'Y' in any of the records, user should not be able to delete this record. In Pre_delete trigger, I put this code
below.
IF :CST_REFERENCE_CODE.SYS_INDICATOR = 'Y'
     THEN
     MESSAGE('You cannot delete this record. Consult your Administrator');
     MESSAGE(' ');
     CLEAR_FORM(NO_VALIDATE);           EXECUTE_QUERY;
--     RAISE FORM_TRIGGER_FAILURE;
     END IF;
I want to clear form an re_query, but the clear form is not working. Help

CLEAR_FORM is a restricted built-in and is not allowed on PRE-DELETE trigger.
the purpose of PRE-DELETE trigger is to do some validation before the actual delete happens and may be delete the child records before the master record can be sucessfully deleted.
it will be better if you could explain that why you need some different functionality on PRE-DELETE trigger, which looks strange. Like, user is trying to delete the record and you want to restrict user from deleting the record if some condition is met and want to re-query. what is the main purpose of doing query here again or why you want to clear the form.

Setting background color in multi record block

Hi all!
I've a table with around 150 records of colors with html-color-names and rgb codes.
I would like to have a sample item in my form 9.0.4 to display the color as a preview for
each record in a multi-record block when querying the table.
I would not like to create a visual attribute for each color. So display_item() is no choice.
(except: somebody show me how to create va's with the japi)
Somebody knows a way to accomplish this?
Thanks in advance and regards
Stauder

Here's a solution which should work :
1. Use a mirror item for the numeric item which has to
be displayed
using the format mask based on value in column1
The data type of the mirror item : Char
X and Y co-ordinates : Same as the item
on which it is
mirrored
Size and Height : Same as the item
on which it is
mirrored
2. On normal display, Mirror item is displayed
3. When Mouse-Click or Pre-Text Item trigger on the
Mirror Item :
- Use the Go_Item ('Actual Numeric Item');
This will bring up the Numeric Item and the Mirror
item goes in hiding
- A VWI trigger on Numeric Item should Then be :
If ( :col1 = 'A' ) Then
:Mirror_Item :=
To_char(:NumericItem, ',999,999.99');
Else
:Mirror_Item :=
To_char(:NumericItem, '99999999');
End If;
4. A key-Next-Item (On Numeric Item) or other trigger ??
should then
use Go_Item (:Mirror Item) to bring forward the
formatted numeric item

Check duplicate data entry in multi record block,which is a mandatory field

Dear all,
I have a situation where i have to check duplicate data entry(on a particular field,which is a mandatory field,i.e. it cannot be skipped by user without entering value) while data key-in in a Multi Record block.
As for reference I have used a logic,such as
1>In a When-Validate-Record trigger of that block I am assigning the value of that current item in Table type variable(collection type)
as this trigger fire every time as soon as i leave that record,so its assigning the value of that current time.And this process continues
then
2>In a When-Validate-Item trigger of that corresponding item(i.e. the trigger is at item level) has been written,where it compares the value of that current item and the value stored in Table type variable(collection type) of When-Validate-Record trigger.If the current item value is matched with any value stored in Table type variable I am showing a message of ('Duplicate Record') following by raise_form_trigger failure
This code is working fine for checking duplicate value of that multi record field
The problem is that,if user enter the value in that field,and then goes to next field,enter value to that field and then press 'Enter Query 'icon,the bolth Validate trigger fires.As result first when-validate record fires,which stores that value,and then when-validate-item fires,as a result it shows duplicate record message
Please give me a meaningful logic or code for solving this problem
Any other logic to solve this problem is also welcome

@Ammad Ahmed
first of all thanks .your logic worked,but still i have some little bit of problem,
now the requirement is a master detail form where both master and detail is multirecord ,where detail cannot have duplicate record,
such as..........
MASTER:--
A code
A1
A2
DETAIL:--
D code
d1
d2 <-valid as for master A1 , detail d1 ,d2 are not duplicate
d2 <--invalid as as for master A1 , detail d2 ,d2 are duplicate
validation rule: A Code –D Code combination is unique. The system will stop users from entering duplicate D Code for a A Code. Appropriate error message will be displayed.*
actually i am facing a typical problem,the same logic i have been applied in detail section ,its working fine when i am inserting new records.problem starts when i query,after query in ' a ' field say 2 records (i.e. which has been earlier saved) has been pasted,now if i insert a new record with the value exactly same with the already present value in the screen(i.e. value populated after query) its not showing duplicate.................could u tell me the reason?and help me out...............its urgent plzzzzzzzzz

Saving the record in multi-record block while updating

Hi gurus
I have a table name PT . Its is master table where PT_TYPE IS unique
desc PT
PT_TYPE VARCHAR2(2) unique,
PT_CODE VARCHAR2(4),This is the detail table on which the form is being designed is meant for insert/update/delete.Insert and delete are working fine.
desc PST
PST_PT_type varchar2(2) unique,
PST_A_code Varchar2(3) unique,
PST_A_desc varchar2(10) The form layout is a multi-record form as below and based on PST table with PT_CODE as non-base table item & PST_PT_TYPE
not displayed but its there in the block.
FORM_LAYOUT
PT_CODE PST_A_CODE PST_A_DESC
ASD          AS          TESTAS
ASD          AD TESTAD
ASD DS TESTDS.
Now the problem is when I am querying record through enter-query mode (say by entering PT_CODE 'ASD') and
change one of the base table items(PST_A_CODE or PST_A_DESC) values and commit it. its says '1 records applied and save'
but when I change ONE OF THE PT_CODE(non-base table item) values it says 3 records applied and saved. as the 3 records
are currently displayed when querying
