Application Express :: Performance Depending On Condition Expression Type
May 24, 2013
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.

APEX 4.1
11g db
Internet explorer 8
I have a region with 4 fields - ID, name, address, telephone. A user can search on any one of theses fields, depending on which field they search on the query is different e.g. Searching on telephone is a different query to searching on address. The query will bring back the same columns, so I just need one report.
How do I create a report where depending on the field the user searches on, it uses the same report but different query.

However our requirement is that in sub region we have a LOV to chose the service, and each service has a price. How can we populate the Price column based on the selection of the Service? There are some similar posts but we cannot apply to our form.

Apex 4.2I currently have a report column in a classic report that has a Column Formatting Attribute as below. This works fine it shows a map icon that when you click on it goes off to google maps and put 2 geo points on a map. However I need to change this report column so that the HTML expression will be different dependent on the value returned so if the column returns 1 then the HTML Expression will be slightly different.
HTML EXPRESSION <span class="map_#BROKE_GEO#_#VALID_GEO_CODES#"><a target=_blank href="f?p=&APP_ID.:323:&SESSION.::::P323_PARCEL_ID,P323_SCAN_ID,P323_PROP_ADDR1,P323_PROP_POSTCODE,P323_PROP_LAT,P323_PROP_LONG,P323_SCAN_LAT,P323_SCAN_LONG:&P341_PARCEL_ID.,#SCAN_ID#,#LINE_1#,#POST_CODE#,#PROPERTY_GEO_LAT#,#PROPERTY_GEO_LONG#,#SCAN_GEO_LAT#,#SCAN_GEO_LONG#"><img src="#WORKSPACE_IMAGES#&P341_IMG_MAP_#BROKE_GEO#." alt="Google Maps" title="Google Maps"></a></span>
I think I can do this in the report source directly with a case statement and include the HTML in that for the column but how do you handle all the quotes within the SQL statement. e.g.
Original Query SELECT parcel_id ,status ,LOCATION ,scan_date ,scan_id ,driver_comments ,card_id ,valid_geo_codes -- this is my html column ,property_geo_lat ,property_geo_long ,scan_geo_lat ,scan_geo_long ,broke_geo ,line_1 ,post_code FROM vw_parcel_history_details WHERE parcel_id = :p341_parcel_id ORDER BY scan_date New Query SELECT parcel_id ,status ,LOCATION
[code].....
various iterations of that large html string but I do not know how to format it because off all the quotes?

My question is, if I define an object type (create type ... as object ...) is it possible to hold a variable of this type as the session level? For example, if I am creating an order using multiple web pages, it would be much easier (and intuitive) to create and manipulate an order object than to hold the data in generic collections.
If that is not possible, is there some way to make a generic Apex collection appear more application specific? By this I mean some way to map the columns C001, C002, ... to more intuitive names such as CUST_NO and ORDER_DATE. I had considered possibly creating a view of the APEX_COLLECTIONS view which would rename the columns but then I would also have to create a bunch of instead of triggers if I wanted to update it as well.

I am using pipelined functions. I've written a few with no problem this one seems to be giving an error when I am using techniques that appear very similar to ones that work.
I am doing this all in a package;
The type definition is;
TYPE SUSPECT_LINKAGES_FAC_RECORD IS RECORD
(
PATIENT_ID TUMOR.TUMOR_PATIENT_ID%TYPE,
CENTRAL_SEQ TUMOR.TUMOR_CENTRAL_SEQ%TYPE,
MP_REVIEW_FLAG NUMBER(1),
FACILITY_FLAG NUMBER
);
The variable definition is;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
The line with the error is;
PIPE ROW(OUT_REC);
This is the entire function;
FUNCTION GET_SUSPECT_LINKAGE_FAC_FLAGS RETURN SUSPECT_LINKAGES_TABLE PIPELINED AS
CURSOR CURS_SUSPECT_LINKAGES IS
SELECT * FROM TABLE(TUMOR_UTILITIES.GET_SUSPECT_LINKAGE_FLAGS())
order by 1,2,3 DESC;
TEMP_REC SUSPECT_LINKAGES_RECORD;
MATCH_COUNT NUMBER;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
[code].....
I get "PL-00382 expression is of wrong type" on both pipe row (out_rec); lines.

I´m newbie as Apex developer using Apex 4.0 with OracleXE 11.2, and now my problem is:
I have a tabular form where one of the columns, when calling the form, is a Display Item, so that you cannot change existing values.
I want, when adding a new row, that column become a Select List (named LOV) based on a query that exclude existing values in other rows already inserted.
Can I change that Display Item to Select List (named LOV) programmatically at runtime? If not, what other options do I have?

I have been searching the forum (and Google) looking for tips on how to ensure users can only upload files of specific formats (Word, PDF, etc) for specific document types as defined within the application (e.g. Curriculum Vitae (Word), Copy of Transcripts (PDF)).
While I have used this research to start work on a server-side solution, I would like to know if there is an apex-friendly way to "validate" a file-browse item based on mime-type.

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?

my sql query has three tables in from clause so it has two join conditions and one where condition.
account_no is number data type and v_account_no is varchar2() data type
The where clause is :
"where account_no=to_number(v_account_no)" with this condition in my sql query has the cost 392
we just modify the where clause as where v_account_no=to_char(account_no) with this condition in the sql query has the cost 11.
what is impact of this data type conversion and difference between these two "to_number() and to_char()" in performance wise to reduce the cost of query?
