i have used radio button under dynamic conditions for an interactive report.eg: radio button values are like a) front end b)middlware c)back end.so based on the selected value of the radio button, interactive report appears. and each fields in radio button have separate set of users. now my issue is,based on the user logging in, the default value should set up while the page is loaded...[i.e... if a front end user logs in, the default value of tat radio button shd be front end...]

I was just wondering what people's thoughts and experiences are regarding performance of conditional expressions.
Tony blogs about it here
[URL}.........
And gives the example
1) Value of item/column in Expression 1 = Expression 2Expression 1: P1_JOB
Expression 2: SALESMAN
2) PL/SQL Expression
Expression 1: :P1_JOB = ‘SALESMAN’>
Recently I've been trying to eke every shortcut I can with an application and noticed this can be a contributing factor when done dozens of times within a page render.

Is it possible to define a cursor using dynamic sql. Reason being is, I want to fetch data from 4 diffrent tables but dont want 4 diffrent cursors for this purpose.
I have a procedure that takes an in parameter . Cursor is declared in this procedure. Again is there a way to use dynamic sql so that this cursor declared in procedure uses all 4 table one at a time i.e cursor c1 is select * from table_name(I want this table name to be updated every time with new table name).

There are several stages for sql processing in 10g2 database concept document.The following stages are necessary for each type of statement processing:
■ Stage 1: Create a Cursor
■ Stage 2: Parse the Statement
■ Stage 5: Bind Any Variables
■ Stage 7: Run the Statement
■ Stage 9: Close the Cursor
Optionally, you can include another stage:
■ Stage 6: Parallelize the Statement
Queries (SELECTs) require several additional stages, as shown in Figure 241:
■ Stage 3: Describe Results of a Query
■ Stage 4: Define Output of a Query
■ Stage 8: Fetch Rows of a Query
Stage 3: Describe Results of a Query The describe stage is necessary only if the characteristics of a query's result are not known; for example, when a query is entered interactively by a user. In this case, the describe stage determines the characteristics (datatypes, lengths, and names) of a query's result.
Stage 4: Define Output of a Query In the define stage for queries, you specify the location, size, and datatype of variables defined to receive each fetched value. These variables are called define variables. Oracle performs datatype conversion if necessary.
I still don't understand what's Stage 3: Describe Results of a Query and Stage 4: Define Output of a Query.

When using this awesome plugin, I have a dynamic action on my calling page that deals with the selection from the dialog.
It uses
Select type:DOM Object
DOM Object: document
Condition: javascript expression
($v('P110_PROD_SEARCH') == 'BLAH')
where the js expression is making sure I run the correct dynamic action, particularly when I have a few buttons on the page invoking different variations of the modal dialog.
My first action is some javascript that interrogates the value of this.data.modalPageCloseValue this facilitates me make decisions in later actions on whether to run some pl/sql, for instance.
potential APEX bug (Display item with HTML affected by dynamic action and since we can't put conditions on actions - I was wondering if I could incorporate something into my dynamic action condition to stop the entire dynamic action from executing if modalPageCloseValue is null - but it seems to be out of scope?

I have used a decode statement in my query instead of using select * from <table_name> where value in <>
Instead I have used decode(value,<value1>, <value2>)
Which would be a better performance code?

small piece of PL SQL code. how to make this query.Requirement is that a concurrent program is run with parameters and one of them i_num_org_id is non mandatory so it can come as NULL...Now in an existing code which i have to change, it uses a query as
SELECT xyz
FROM abc_table
WHERE <various conditions>
AND DECODE(i_num_org_id,NULL,1,table.organization_id) = NVL(i_num_org_id,1);
Now with the above way, if the program is run with some value for i_num_org_id or run as normal query (with NULL as the value) inside a PLSQL procedure/package then it runs fine.This query if you run in Toad etc then too it will work fine but if it is made a dynamic SQL and then used as either EXECUTE IMMEDIATE or opened as a cursor then we get a "Missing expression". I created this small anonymous block to test this and this will go into missing expression error
declare
l_num_org_id NUMBER := NULL;
l_temp VARCHAR2(100);
l_sql varchar2(1000);
begin
l_sql := 'SELECT '||''''||'abcd'||''''||'
[code].....
how i can reformat this query so that even if NULL value comes for i_num_org_id then it is handled.I am aware about CASE but that cannot be used in WHERE clause i guess.

Declare nextID NUMBER(22);BEGINselect lag(ref_contact_id, 1,0) OVER (ORDER BY ref_contact_id)into nextID from (select ref_contact_id,lead(ref_contact_id, 1,0) OVER (order BY ref_contact_id) as "NextNbr", lag(ref_contact_id, 1,0) OVER (order BY ref_contact_id) as "LastNbr"from (select rc.ref_contact_id from REF_CONTACT rc order by FIRST_NAME ))where ref_contact_id = 793 ;END; The returned value is 0.
I understand why but not how to pull the next value base on a particular ref_contact_id.

The SQL Query portion of Authorization Schemes are deleted or set to NULL after editing. Re-entering the SQL Query will not save the SQL, so the SQL Query is lost.
I had to update WWV_FLOW_SECURITY_SCHEMES.ATTRIBUTE_01 via sql to restore and modify the SQL Query portion of the Authorization Schemes.

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.

I have stacked into something: if there is a way to define a single row form page based on table in which I could query and update without using a tabular page (to call the single row form). I want only to use only one page. Does APEX has this functionality?

I am using Apex 4.1 and have a requirement to create an interactive report based on a dynamic query. This option is available in Classic report but in Interactive this feature is not there. Tried using collections or just a view (thought of changing the view definition during "On load", but structure of the report is already defined based on the definition of the view at design time).
Is there any way of achieving this?

I am having a problem with a popup lov. When I click on the "popup icon" I can select a supplier and it is stored in the field. But when I leave the form and return later, it shows the return value instead of the display value. For example: you select "supplier A" from the popup list with ID 12. "Supplier A" is shown in the text field, when you save the form, it stores ID 12 in it. But when you return to the form, it fetches ID 12 and shows "12" in the text field instead of "Supplier A".
I tried setting the "source" of the popup lov field as an SQL query, but that didn't work for me.

I am trying to create a tabular form based on a SQL query, that has a query-based select list with a where clause that references a column in the originating SQL query.
The situation is, I have a table that stores client_id, source_id and build_id, lets call it client_source. I have a second table, build_source, that contains source_id and build_id, with a one to many relationship between the two (source_id of 1 could have build_id of 1-7).
Using a tabular form, I want to select the corresponding build_id to be used in client_source, but the select list must only contain the build_id's for that rows particular source_id.
Here is an example of the SQL source of my tabular form;
select
s.ROWID,
s.CLIENT_ID,
s.SOURCE_ID,
APEX_ITEM.SELECT_LIST_FROM_QUERY(1, s.BUILD_ID,
'select b.build_id display, b.build_id return from
build_source b where b.source_id = s.SOURCE_ID ') lst
from client_source s
... what I am trying to achieve is that the source_id fields in bold match. When the query is built this way I get an 'invalid identifier' Oracle error on s.SOURCE_ID at runtime.
Is there some special tags that need to be used to reference the outside column?I am running on Application Express 4.1.0.00.32, on a Oracle 10g release 10.2.0.4.0 database.

I have this procedure
POSTCODE_TO_LAT_LNG_GM_API(postcode IN VARCHAR2, lat OUT NUMBER, p_long OUT NUMBER)
to convert a postcode into lat/long values. I then need to add them to the returned SQL statement so I used the string concat operator || with to_char but it comes up with this error when I try to apply the changes: Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic column'' checkbox below the region source to proceed without parsing.
