Execute UPDATE From Field That May Have More Than Row
Jun 29, 2010
I am trying to execute an UPDATE from a field that may have more than row. I get ORA-01427: single-row subquery returns more than one row.
I need to set the careof column in owner table to hold the name (NAM) from the alt table if the alttype from alt is ATT. We could have more than one id and the careof names can be different.
This is my query:
UPDATE owner s
SET s.careof = (SELECT a.NAM
FROM alt a
WHERE a.taxyr = '2011'
AND a.alttype = 'ATT'
AND a.card in ('0')
[code]....

I have a table where i need to update one field values based on another field of the same table , simply as it is.I have done this using one select all check box , on clicking that all check boxes of item_trans table will get selected , then i will un select some of check box and then using one button, i will update the value of the fields which are checked only.
I have put the sample code but when i am updating its taking long time and hanging.I am also attaching the form based on the test case provided.
--tables with insert statement
create table item_trans (trans_item varchar2(12),trans_qty number,trans_act_qty number)
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE1',40,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE2',20,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE3',20,NULL);
--i want to set the value of trans_Act_qty as trans_qty
--i create one dummy or test block to keep the select all check box. for that table test script is
CREATE TABLE TEST
(
C VARCHAR2(2000 BYTE),
B NUMBER,
A NUMBER
);
insert into test (C,B,A) values ('A',1,1);
--code written in select all check box which is created on test.block.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
:M_END_YN := :M_END_ALL;
[code].......
--code written in M_END_YN ( actual check boxes where i will uncheck).
IF :M_END_YN = 'N' THEN
:M_END_ALL := 'N';
END IF;
--code written on button to update those values which are checked.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
IF :M_END_YN = 'Y' THEN
[code]......

I am encountering an error message while updating a xmltype column using dynamic sql statement. I am using dynamic sql here as the table is not placed in the same schema from where the plsql procedure is invoked. The schema name is passed to the procedure as an argument. I am using below pseudo code for this purpose.
Create procedure myproc(p_schemaname varchar2, p_id number)
is
p_clob clob;
p_str varchar2(2000);
begin
[code]...
This is throwing an error 'missing expression' at the line of 'exeute immediate'.
But it works if I run a static sql update by hard coding the schema name in the statement.

Trying my best to follow the posting guidelines.
There are two tables.
orderheader and orderdetails. orderheader is a master table and orderdetails is a detail table. So for every one record in orderheader table, there are many records in orderdetails table. I want to update a field in orderdetails table from a orderheader table using inner join.
update orderdetails
set orderdetails.conversion_dt =
(select orderheader.conversion_dt
from orderheader, orderdetails
where orderheader.number= orderdetails.number )
I get the following error:
Error report: SQL Error: ORA-01427: single-row subquery returns more than one row 01427. 00000 - "single-row subquery returns more than one row"
*Cause:
*Action:
What mistake am I doing here?

I'm editing, say, list of my employees in a tabular form opened in Skillbuilders Modal Page. I have to execute same javascript code after the changes in the tabular form have been submitted.
I've tried using a Dynamic Action fired on Page Load, but that gets executed before the update is completed.

I have seen in probably VB or Dot net software being used at some premises that there "formula computation is live and interactive".
What i means that suppose a cashier has made invoice having total of 83$. Mow in the text box for entering amount received, the cashier is about to enter 100 but surprisingly the returned value/remaining value (total invoice - amount received) is being computer LIVE.
This is what happens.
1) The cashier entered 1 and the remaining value instantly showed 82 (83-1)
2) then on other key stroke of 0 by cashier and then then the remaining value instantly showed 73 (83-10)
3) then on other key stroke of 0 by cashier and then then the remaining value instantly showed 17 (83-100)
Hence a continuous updation/changing of the remaining value on every key stroke is observed.

We are using APEX 4.2, 10GR2, RedHat5.
I have a report that comes from SQL Query (updateable report). I'm using the apex_item.text and apex_item.hidden on fields. I'm using a button to submit and after submit process to add some logic that I need.
There could be 1 - 10 records in the report. There is only 1 field that is needed to enter a value, but the value of this field determines the value of another field. I think that I can do this with a submit button and an after submit process where I loop through all the records. I think I have this handled.
This is the question
When the value of that field is changed then the value of another field in the same row changes immediately. All the examples I've seen so far are for a single record and that doesn't work for us.
I guess this is a MRU process but I haven't seen an example where a dynamic action is possible on a Multi Row Update.

Let's say that we have an order entry app and the price and quantity items are already populated. We now want to show the user the extended price (the product of the first two items). the extended price would automatically display after both the quantity and price items are entered. I'm assuming that would require some kind of client-side processing. I imagine server-side processing is simpler, so I'll lean in that direction. I'm sure we've all seen web sites that require you to click a button for the order totals to be updated. I'm okay with that approach, but I haven't quite put all of the pieces together. Here's what I came up with.
A region button was added to trigger the updating of the extended price. The button's "Action When Button Clicked" is to submit the page. Under "Page Processing", a process was created to do the calculation with the recipient of the product being a page item. From debug code in the procedure, I can see that the item containing the extended price was, indeed, modified. But the new value doesn't display in the field and the Session window shows that the value of the item didn't change.
I must be missing something. The debug code says the item value was updated. The Session window says it wasn't updated. What gives? What did I do wrong and what needs to be done to correct this?

Environment:
Apex 4.2
DB 11gR2
I've started using Apex 4.2(new to Apex). I have built a form based on a table with a date column on it. The form allows update on all fields/columns of the base table. For the date field/column, the goal is to present the user with sysdate on load and update the date with sysdate if the record is changed any of the fields. How can I accomplish this?

I'm trying to update a number field on an apex page by summing up the values of multiple page items. I've tried to follow this tutorial
[URL]........
especially the "Create a Set Value Dynamic Action Using PL/SQL" part.
In the tutorial example they return an page item value P3_SAL multiplied by a multiplier they've determined by another page item's case. What I want to do is much simpler in that I just want to add up multiple page item values and then display them in a number field at the bottom of the page.
so the code I tried to use based on the tutorial is in the tab: Home >Application Builder>Application 103>Page 3>Edit Dynamic Action>Create / Edit Action
Set Type: PL/SQL Function Body
PL/SQL Function Body:
BEGIN
return :P3_ITEM1+P3_ITEM2+P3_ITEM3;
END;
Page Items to Submit: P3_ITEM1,P3_ITEM2,P3_ITEM3
But it gives me an error that I need to declare the identifiers, yet it works if I only use one item and I can perform any arithmetic.
i.e.
BEGIN
return :P3_ITEM1+1000;
END;

I'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS
(SELECT ph.* FROM po_header ph WHERE 1 = 2),
pf AS
(SELECT DISTINCT pf.order_id, pf.fund
FROM po_fau pf, ph
WHERE 1 = 1
AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746
po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor;
dbms_sql.parse(nDDL_Cursor, sSQLStr, 2);
FOR x IN 1 .. nCols LOOP
sCols(x) := '';
dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100);
END LOOP;
nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.

I am New to Apex. Im using Apex Version 4.2.
I have a tab named APPROPRIATIONS it has 10 fields. Among which is PROJECT NUMBER, AUTHORIZAION DATE (CALENDER TYPE POPUP), And FUNDS CHECK FLAG.
The Scenario is depending upon PROJECT NUMBER the Fields are Populated including FUNDS CHECK FLAG .
But the AUTHORIZAION DATE is a MANDATORY field has to be filled by User
The Requirement is to make AUTHORIZAION DATE as MANDATORY only when the FUNDS CHECK FLAG is *"BLANK "* or *“Y”*
If the FUNDS CHECK FLAG is *“N”* then the AUTHORIZAION DATE to be made OPTIONAL.

I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?

This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.

*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
