Need Post Query Workaround - HELP!
This is urgent. Any help will go along way.
I am using Forms Builder 6i version 6.0.8.13.0.
I am designing a web based form that has 6 blocks.
Blocks 1, 3, 5 and 6 are all related via relation objects in the form.
Block 1 is a key block used as a lookup. Users enter data in this block for which they are looking for related information. It will only contain 1 record, all other blocks are multi-record capable.
Block 2 populates programatically based on data entered in block 1. It is excluded from the navigation sequence.
Then upon navigating to block 3 from block 1 the rest of the form/blocks populate with all the related data to the key values entered in block 1.
Here's my problem.
I need block 4 to populate for every row returned in block 3. Block 4 is not and can not be related to block 3 via a relation object. I now have it populating programaticlaly based on the click of a button that the user has to press after all data is retrieved or whenever they scroll to a new record in block 3 - not good for the user. What I want to do is have block 4 populate automatically as rows are retreived into block 3. That way as the user scrolls through the data in block 3 the data in block 4 will change to reflect.
The difficulty is that a post query will not work because in the procedure that populates block 4 I need to use a next_record built-in. Block 4 is not a base table block. It is a mulit-record display block (6 records displayed at a time) with a scroll bar. So in order to programatically populate it I have to fill the first row then move to the next record and fill it and so on and so on.
I need a work around.
I need a way to let block 3 be queried for records and as each one comes into the block call the procedure to populate the other block - remember that the procedure uses next_record and post query does not like the restricted built-in. I tried to use when_new_record_instance to call the procedure. This allows the data to be queried and as the user scrolls through the data block 4 populates on each new record. It did not work.
I realize this problem may be hard to clearly understand from my description so if anybody has the interest in solving a week long problem you can fire away your suggestions or email me at [email protected].
Maybe I can send you a screen shot to clarify the layout a little better.
Thank You.
Brian,
You can try this method, which will definately work.
As you have mentioned you want the module to automatically query Block4 based on the information ob Block 3.
You can write a form procedure which programitically populates BLOCK4. This procedure can be called from the KEY triggers which allows restricted procedures to be used.
Try this :-
1) Create Key-Up, Key-Down triggers on Block3.
Example :-
Key-Down Trigger On Block 3
Declare
lCurrRowPos Varchar2(10);
Begin
Next_Record; /* The cursor is on Block 3 */
lCurrRowPos := :System.Cursor_Record;
Go_Block ('BLOCK4');
Clear_Block (No_vALIDATE);
Execute_Query;
OR prg_populate_block4l
First_Record;
Go_Block ('BLOCK3');
Go_Record (lCurrRowPos);
End;
Key-Up Trigger On Block 3
Declare
lCurrRowPos Varchar2(10);
Begin
Previous_Record; /* The cursor is on Block 3 */
lCurrRowPos := :System.Cursor_Record;
Go_Block ('BLOCK4');
Clear_Block (No_vALIDATE);
Execute_Query;
OR prg_populate_block4l
First_Record;
Go_Block ('BLOCK3');
Go_Record (lCurrRowPos);
End;
This way whenever the cursor moves up and down the block3 the information is automatically displayed in BLOCK4.
Hope this helps.

in edusource database i have location and columns like countryname,statename,feildtext,descriptiom,isactive
i need to insert data in edusource
database of tbl_ maplocation from that that databaseTry this out:
DECLARE @geog TABLE (ID INT, type VARCHAR(20), Abrev VARCHAR(6), name VARCHAR(30), parentID INT, Active VARCHAR(5))
INSERT INTO @geog (ID, type, Abrev, name, parentID, Active) VALUES
(1 , 'Country' ,'In ', 'India ', NULL, 'TRUE'),(2 , 'Country' ,'Aus ', 'Austrilia ', NULL, 'TRUE'),
(3 , 'Country' ,'Usa ', 'United States of America', NULL, 'TRUE'),(4 , 'Country' ,'Uk ', 'Great Britian ', NULL, 'TRUE'),
(5 , 'State' ,'AP ', 'Andhrapradesh ', 1 , 'TRUE'),(6 , 'State' ,'MH ', 'Maharastha ', 1 , 'TRUE'),
(7 , 'State' ,'TN ', 'Tamilnadu ', 1 , 'TRUE'),(8 , 'State' ,'Sdy ', 'Sydney ', 2 , 'TRUE'),
(9 , 'State' ,'MEL ', 'Melbourne ', 2 , 'TRUE'),(10 , 'Location' ,'IN-Hyd', 'Hyderabad ', 1 , 'TRUE'),
(11 , 'Location' ,'In SEz', 'Sez-Hyderabad ', 1 , 'TRUE')
SELECT g1.ID, COALESCE(g2.name,g1.name) AS countryName, g1.name AS stateName, g1.name AS fieldText, CASE WHEN COALESCE(g2.Active,'TRUE') = 'TRUE' AND g1.Active = 'TRUE' THEN 'TRUE' ELSE 'FALSE' END AS Active
FROM @geog g1
LEFT OUTER JOIN @geog g2
ON g1.parentID = g2.ID
AND g1.type IN ('location','state')
WHERE g1.Active = 'TRUE'
AND COALESCE(g2.Active,'TRUE') = 'TRUE'
I think you may want to further the relationship, and have 10 be the parent for 11, so you can get country, state, location. -

Please help me......
There is one complex requirement in matrix format.
Need P_ID , P_NAME , Count( child records)
P_(nth), P_NAME(nth), Count(child record) nth times.
Child is again the parent of some child.
Report is needed for audit purpose.

Performance issue on query. Help needed.
This is mainly a performance issue. I hope someone can help me on this.
Basically I have four tables Master (150000 records), Child1 (100000+ records), Child2 (50 million records !), Child 3 (10000+ records)
(please pardon the aliases).
Now every record in master has more than one corresponding record in each of the child tables (one to many).
Also there may not be any record in any or all of the tables for a particular master record.
Now, I need to fetch the max of last_updated_date for every master record in each of the 3 child tables and then find the maximum of
the three last_active_dates obtained from the 3 tables.
eg: for Master ID 100, I need to query Child1 for all the records of Master ID 100 and get the max last_updated_date.
Same for the other 2 tables and then get the maximum of these three values.
(I also need to take care of cases where no record may be found in a child table for a Master ID)
Writing a procedure that uses cursors that fetches the value from each of the child table hits performance
badly. And thing is I need to find out the last_updated_date for every Master record (all 150000 of them). It'll probably take days to do this.
SELECT MAX (C1.LAST_UPDATED_DATE)
,MAX (C2.LAST_UPDATED_DATE)
,MAX (C3.LAST_UPDATED_DATE)
FROM CHILD1 C1
,CHILD2 C2
,CHILD3 C3
WHERE C1.MASTER_ID = 100
OR C2.MASTER_ID = 100
OR C3.MASTER_ID = 100
I tried the above but I got a temp tablespace error. I don't think the query is good enough at all.
(The OR clause is to take care of no records in any child table. If there's an AND, then the join and hence select will
fail even if there is no record in one child table but valid values in the other 2 tables).
Thanks a lot.
Edited by: user773489 on Dec 16, 2008 11:49 AMNot sure I understand the problem. The max you are getting from the above is already the greatest out of the three - that's why we do the UNION ALL.
Here's sample code without output, maybe this will clear it up:
with a as (
select 10 MASTER_ID, to_date('12/15/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 20 MASTER_ID, to_date('12/01/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 30 MASTER_ID, to_date('12/02/2008', 'MM/DD/YYYY') LAST_DTE from dual
b as (
select 10 MASTER_ID, to_date('12/14/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 20 MASTER_ID, to_date('12/02/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 40 MASTER_ID, to_date('11/15/2008', 'MM/DD/YYYY') LAST_DTE from dual
c as (
select 10 MASTER_ID, to_date('12/07/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 30 MASTER_ID, to_date('11/29/2008', 'MM/DD/YYYY') LAST_DTE from dual UNION ALL
select 40 MASTER_ID, to_date('12/13/2008', 'MM/DD/YYYY') LAST_DTE from dual
select MASTER_ID, MAX(LAST_DTE)
FROM
(select MASTER_ID, LAST_DTE from a UNION ALL
select MASTER_ID, LAST_DTE from b UNION ALL
select MASTER_ID, LAST_DTE from c)
group by MASTER_ID;
MASTER_ID MAX(LAST_DTE)

hii
i need a query help
i have two tables
the 1st table will look like this
associate id weekid no.of. hours
4000 810 40
4000 820 30
4000 830 60
4000 840 70
2nd table will look like this
associate id weekid no.of.hours
4000 810 40
4000 820 70
4000 830 130
4000 840 200
so when i subtract the last two records frm each other in the second table the value should be equal to the no.of.hours in the first table.. for example
the query shud consider the last record and one before the last record and the difference between two records shud be equal to the value in the 1st table
for example
consider week id 830 and 840
in second table 830=130
840=200
when u subtraced both values the difference shud be equal to value in the 1st table for tht week id
1 ---->>>> 840 - 830
=200 - 130
=70
in first table 840 has 70 hrs
like this it shud check with all records and it shud return only the records which are not equal

Urgent Help Needed Union Query
Hello All
I have a complex query (at least i think) which returns result set. Now i want to add to it the records that were not mached by the query i tried
<Query1>
Union all
<Query2> where not in <query1> (hope i am able to express myself)
but it takes a lot of time
is there any way that query1 is refered once or i have to redefine the query
Any Help ??????
Thanks in advanceI think i am unable to clearly express myself
When i try to use outer join error occures end-of-file on communication channel. actualy i have a poorly designed database structure which is not in my control but i am supposed to report on it
<query1>
union all
<Query2> where not in <query1>
i wanted to say query 1 returns a result set and query 2 reurns rows not selected by query 1
any workaround -

Cursor C5 is select task_desc,decode(substr(task_desc,1,3),'WBC',to_char(num_value,'fm99.0'),
'RBC',to_char(num_value,'fm99.90'),
'HGB',to_char(num_value,'fm99.0'),
'HCT',to_char(num_value,'fm999.0'),
'PLT',num_value,num_value) as value,alpha_value
from qc_task_poch_results A,QC_TASKS B
where a.task_id = b.task_id
and a.procedure_id = 1127
and drive_id = 'DRV5528593'
Begin
Open C5;
Fetch C5 into :qc_task_results_poch.num_value
,:qc_task_results_poch.alpha_value;
Close C5;
End;
But I amm not getting the formatting.
The column in the form is non database .
When I run in toad, I get the right formatting.
TASK_DESC|VALUE|ALPHA_VALUE
WBC count|3.0|
RBC count|2.33|
HGB count|6.0|
HCT Count|17.0|
PLT count|56|
Any help is appreciatedYou are formatting your data in your select statement not in Forms. Consequently, any format mask you may have on the Item where the data will be display will reformat your data to match the Item's format mask.
Do you have the format mask property defined on the Item? What is the data type of the item?

Hello.
I'm a newbie here.
I'm currently studying Oracle Form Builder and I'm a student.
I've encountered this problem where I need to create a post-query trigger in a data block that counts a total number of rows in a particular item using a display item.
I'm know I need to use the INTO clause to populate the display item but I got stuck.
Please help.
Thank you very much..First of all your code to calculate the total rows returned from a query is wrong.
Try this one in a Post-Query Trigger
DECLARE
total_rows_returned NUMBER;
BEGIN
SELECT COUNT(*)
INTO total_rows_returned
FROM table_name;
:block_name.display_item := total_rows_returned;
END;
Good Luck

Post Query Trigger with cursor
Good afternoon to all of you!
I need your help. I create a master detail form. I created also a post quey trigger, inside I wrote the code below.
A cursor looks to another table and returns to the form some values i need!
declare cursor C1 is select apofaa,startdate,enddate,transport
from trapofdet
where trapofdet.apofcode = :trapof.apofcode;
begin
open C1;
loop
fetch C1 into :TRAPODOSI_NEW_NEW.APOFAA, :TRAPODOSI_NEW_NEW.STARTDATE, :TRAPODOSI_NEW_NEW.ENDDATE, :TRAPODOSI_NEW_NEW.TRANSPORT;
exit when C1%notfound;
next_record;
end loop;
close C1;
first_record;
null;
end;
How to solve the a. frm-40737, illegal restricted procedure go block in post-query trigger
b. It seems tha returns all the records but it appears only the last one.
Please can anybody help with these?
Thanks in advance!
ChristosChristos,
The Post-Query trigger will fire once for each record returned to your form therefore you need to write your query to return a single row rather than a multiple rows. Using the Post-Query trigger to fetch additional data into your form can cause your form to be very slow - depending on the number of records returned and how many columns are fetched by your Post-Query cursor as well as how quickly the query executes.
Is your Post-Query trigger on your Master or Detail block. Are you using the Post-Query trigger to populate your Detail block? Are you using a Block Relationship to coordinate your Master and Detail blocks?
Also, it is helpful to know which version of Oracle Forms you're using.

FROM acnts
where CCODE = :xH_ccode
and Tcode = :XH_tCODE

the 1st row returned should be saved in r1c1 r1c2 r1c3 r1c4
and the 2nd row returned in r2c1 r2c2 r2c3 r2c4
if the query returns 2 rows
i tried to incorporate it in thiS way, but needs SOme help;

:= . ( @ % ; indicatorTYVM, Mr. Kuba,
those 4 rows r1c1....did get filled properly. I have now 1 more problem. about this form so,
I have a columnar tables
inventotry_header (Inv_head) and
inventory_detail (Inv_detail)
in post-database-commit i am saving some details in to a 3rd table, ACNTS
Inv_head is linked to inv_detail thru primary-foreign key, table ACNTS is independant.
i have joined inv_head==>ACNTs in forms.
i wrote this post-query Suggested by you. i want to display ONLY the control fields r1c1.....
derived from the acnts table in post query and keep acnts table fields hidden.
the acnts table should just be saved in the background(in post-database-commit) and
its values will be displayed on form thru the control fields.
but when i make the visible property of the acnts table fields to "NO", the post query result does not display
the control fields r1c1.... and on querying, at first record it gives error,
FRM-40106 No navigable items in destinations block
and why i dont want to use the acnts tables for display, because i want to assign & display the control fields
as i enter the details in inv_head and inv_detail, in the sequence of r1c1 r1c2 r1c3 r1c4....
which i dont think will be possible with acnts tables (which is a linked actual db table).
hope i have made it clear. -
Hi all i need help

Thanks
-SamsamHi,
Do two things First check that when ur form opens no field in ur form is getting value from anywhere. May be through parameters or through when new form instance.
Second Do not use exception When others use exception
when no record found. Try these things. hoping that first point will solve ur problem. -
I am trying to program a report to query a list of customers and ytd charter dates for cusomters whose ytd charter cost is greater than the avg ytd charter cost of all customers. This is what I have written:
[ACCEPT fiscal_year char PROMPT 'Enter the four digit year:'
SELECT c.cus_lname||''||c.cus_fname,
ch.char_trip,
RTRIM(TO_CHAR((ch.char_DISTANCE*MO.MOD_CHG_MILE)*1.35,'$99,999.99'))
FROM charter.customer c JOIN
charter.charter ch
ON c.cus_code = ch.cus_code
JOIN charter.aircraft a
ON ch.ac_number = a.ac_number
JOIN charter.model mo
ON a.mod_code = mo.mod_code
GROUP BY c.cus_lname||''||c.cus_fname,ch.char_trip,
WHERE
ch.char_date = ADD_MONTHS(TO_DATE(CONCAT('10-01','&fiscal_year'),'mm-dd-yyyy'), -12) AND
where ch.char_distance >
(select avg(RTRIM(TO_CHAR((ch.char_DISTANCE*MO.MOD_CHG_MILE)*1.35,'$99,999.99'))))
from charter.charter ch
where RTRIM(TO_CHAR((ch.char_DISTANCE*MO.MOD_CHG_MILE)*1.35,'$99,999.99')) = avg(RT\
RIM(TO_CHAR((ch.char_DISTANCE*MO.MOD_CHG_MILE)*1.35,'$99,999.99'))))
Tables include:
charter: char_trip{pk}, char-date,ac_number{fk2},destination,char_distance,cus_code{fk1}
customer:cus_code{pk}, cus_fname, cus_lname,cus_address
aircraft: ac_number{pk}, mod_code{fk1}
Model: mod_code{pk}, mod_chg_mile
Total miles are calculated by ((distance * mod_chg_mile)*1.35)
When I run this I get the following:
old 13: ch.char_date = ADD_MONTHS(TO_DATE(CONCAT('10-01','&fiscal_year'),'mm-dd-yyyy'), -12) AND
new 13: ch.char_date = ADD_MONTHS(TO_DATE(CONCAT('10-01','2008'),'mm-dd-yyyy'), -12) AND
WHERE
ERROR at line 12:
ORA-00936: missing expression
Unsure what to do, Ihave tried many variations to correct but only get other errors. I cannot seem to get it correct.
Thanks in advance..
BarbHi, Barb,
You should develop code in very small steps. For example, make sure you can get the right data for all customers, then refine that query so it only includes csutomers with above-average costs. If you do that, you'll be able to find more errors yourself and, if you need to ask for help, it will be clearer what your problem is.
The query you posted has lots of errors:
(1) What is the formatted number you're displaying? You're doing a GROUP BY query, so it's probably the result of some group function (like SUM or AVG).
(2) You can't put a comma at the end of the GROUP BY clause
(3) GROUP BY comes after WHERE
(4) In the TO_DATE statement, there is one hyphen in the first argument, but two hyphens in the second. (This is not really an error, but you don't need CONCAT: see below.)
(5) AVG requires a number argument. You can't use a formatted string (with $ and ,). Use the actual numbers (such as ch.char_distance*mo.mod_chg_mile*1.35 is a number).
(6) There are lots of mistakes involving parentheses in the subquery. Use newlines and tabs to make matching parentheses line up.
So write a query that displays all the information you want for all customers. (The query below is my best guess.)
When you have that much working, post another question like this:
Subject: Showing Above-Average Rows Only
I have this query ...
it produces these results ...
I want to show only the rows where ytd_charter_cost is above average for the result set.
That is, instead of all the rows above I want only these rows ...
-- Query for all customers
-- Numbers (1), (2), ... in comments refer to points listed above
SELECT c.cus_lname||''||c.cus_fname,
ch.char_trip,
RTRIM ( TO_CHAR ( SUM ((ch.char_DISTANCE * MO.MOD_CHG_MILE) * 1.35) -- (1)
, '$99,999.99'
) -- (6)
FROM charter.customer c
JOIN charter.charter ch
ON c.cus_code = ch.cus_code
JOIN charter.aircraft a
ON ch.ac_number = a.ac_number
JOIN charter.model mo
ON a.mod_code = mo.mod_code
WHERE ch.char_date = ADD_MONTHS ( TO_DATE ( '10-01-&fiscal_year' -- (4)
, 'mm-dd-yyyy'
, -12
GROUP BY c.cus_lname||''||c.cus_fname,ch.char_trip; -- (3)
