Application Express :: Using Variables In PL/SQL Function Body Returning SQL Query?
Nov 20, 2012
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.
ORA-00936: missing expressionh4.
h4. btw I'm using Oracle 11g release 11.2.0.3.0 and Apex version 4.1.1.00.23
DECLARE
l_lat NUMBER;
l_lng NUMBER;
l_SDO_GEOMETRY SDO_GEOMETRY;
[code]...

Application Express 4.1.1.00.23 ( plus all earlier versions that I've ever used)
When using the wizard to create a Validation of type "PLSQL Function returning Boolean", why is it mandatory to enter a value in the text field "Error Message" on the screen that follows? This message is never used as the message actually displayed comes from a PLSQL return statement.

I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.

Apex Version: 4.2.0.00.27Theme: 25 I have a page that I need to divide by 8 segments, rather than 12 ( I will need to place items and buttons in one of the 8 columns). To begin, I have made a copy of the One Level Tabs - No Sidebar page template. I have tried to edit this template, and played with multiple combinations changing the Grid Layout and Display Points settings, but instead of creating a page that has 8 columns, that span the width of the page, I am just left with blank space. See attached:.[URL] And these are the Page Template Settings:[URL] Is it possible to change the body section of the page template to have 8 columns span the entire width, without the dead space?

I have made Horizontal Wizard Progress List over 3 pages.I also made those 3 pages with some simple text fields, checkboxes and so on.On the last page I did the INSERT Process (session variables P100_Date ect).It worked fine! But now I tried a different approach
On each of the 3 pages I made a "Form on a Table or View" and on each pageI hide some of the form. (the advantage of this situation is, that apex gives you a visaul hint about the null fields and so on).But on the last page I cant do the INSERT with the session variables.(I can do the INSERT without session variable, with static values)...

I need to include the above function in a plsql package. How I can declare a object type and table type in a pks file? the syntax to include the above code in a .pks and .pkb file?
I got this code snippet online when I was looking for function that returns a table type. what exactly that Exception block does? delete the table when there is an exception, otherwise return the table type?

how to write a function that returns top value if not exists then next top for combination of customer_id and hierarchy.For instance :
If I've got table
customer_id ,hierarchy, function_code
123 |1 | Z1
123 |2 |67
123 |3 |5B
678 |10 |S2
678 |11 |Z2
345 |2 |11
For the customer ID 123 I want to return Z1, for customer 678 I want to return S2 and for customer ID 345 I want 11
Problem is that I'm new to the concept of looping. I know how to write a function that accepts customer_id as a value write a cursor and then check IF hierarchy = 1 the return FUNCTION_CODE IF hierarchy - 2 THEN ...
but I need something more universal as some of the customers may have hierarchy function 1 and that would be the top one for him but others might have function of hierarchy 10 as top and checking all of the possibilities using if would be just stupid. So how to write something universal ? And of course if function did not find any customer_id then return null.

I have the following function that I am using as a template for any function that executes a select statement and return a single value as an output.
The function is working but I wanted to take an expert opinion if it can be optimized.
CREATE OR REPLACE FUNCTION AFESD.F_AGR_GET_AGREEMENT_SERIAL
(I_NUMBER0 IN NUMBER, S_SUB_NUMBER VARCHAR2 DEFAULT NULL, I_TYPE_ID NUMBER)
[Code]....
In addition I want to use the parameter S_SUB_NUMBER that can be NULL and add it to the select statement of the cursor, but I dont know how to do that in one statement.
CURSOR C_AGREEMENT
IS
SELECT AGREEMENT_SERIAL
FROM VW_AGR_AGREEMENT
WHERE NUMBER0 = I_NUMBER0
AND TYPE_ID = I_TYPE_ID
-->and sub_number is null;
-->and sumb_number = s_sub_number

I've seen several code samples that show how to return a REFCURSOR from a Stored Function, but when I try it with C# it gives me allways WRONG NUMBER OF ARGUMENTS or somehing like that.
I presently don't have my code in here, but it is something like this:
cmd.Parameters.add ("parRefCursor", dbresult.RefCursor, direction.Result);
I'm being able to use it as a OUT parameter, but I would like to have it as a RETURN value from a Function.

DECLARE
cnt number(10);
BEGIN
SELECT COUNT(*) INTO CNT FROM TBL_ADDRESS WHERE ADDRESS_ZIP
IN (SELECT * FROM TABLE(MY_PACK.STR2TBL('46227')));
DBMS_OUTPUT.PUT_LINE (cnt);
END;
MY_PACK.STR2TBL() is a function which takes '|' delimited string, extracts values and returns a table of zipcodes. The function works fine and returns 46227 but the count returned is 0 instead of 280(count returned by replacing inner select with '46227').

I have a requirement to be coded like this:
A function to return pl/sql table(cant use ref cursor) whose columns varies every time it runs i.e,
means
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000))
type pl_tab is table of pl_tab_type
func f return pl_tab
as
...
end;
note : pl_tab_type will vary for each run of function f
i.e.,for example, pl_tab_type can be changed to as follows:
type pl_tab_type is object(col1 varchar2(1000), col2 varchar2(1000),col3 varchar2(1000))
how to return pl/sql table of dynamic type from func,

I have a problem when trying to create a PLSQL function based on an XML extraction query.
I have three dummy tables:
SQL> get create_address
1 create table ADDRESS
2 (
3 id NUMBER not null,
4 house_number NUMBER,
5 house_name VARCHAR2(20),
6 street_name VARCHAR2(30),
[code]....
And the following dummy data for these:
1 insert all
2 into ADDRESS (ID, HOUSE_NUMBER, HOUSE_NAME, STREET_NAME, CITY, COUNTY, POSTAREA, POSTSTREET)
3 values (1, 1, '', 'Tube Street', 'Norwich', 'Norfolk', 'NF12', '2DF')
4 into ADDRESS (ID, HOUSE_NUMBER, HOUSE_NAME, STREET_NAME, CITY, COUNTY, POSTAREA, POSTSTREET)
5 values (2, 5, '', 'Dave Street', 'Edlington', 'Kent', 'CT34', '8GH')
6 into ADDRESS (ID, HOUSE_NUMBER, HOUSE_NAME, STREET_NAME, CITY, COUNTY, POSTAREA, POSTSTREET)
[code]....
So far so good then. But, what I want to create is a function where I can pass in an id value and return the corresponding XML CLOB.
So I try, very simply, this:
SQL> get get_xml_data
1 create or replace function get_xml_data(p_id in number) return clob is
2 Result clob;
3 begin
4 select xmlroot(xmlelement("HomeData",
[code]....
And, alas, i'm greeted by this:
SQL> /
Warning: Function created with compilation errors.
SQL> sho err
Errors for FUNCTION GET_XML_DATA:
LINE/COL ERROR
-------- -----------------------------------------------------------------
4/5 PL/SQL: SQL Statement ignored
24/63 PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got -

I've tried to redo the query in several different ways but so far nothing.

I want to build a custom authentication scheme which combines the funcionality of of SSO and a custom authentication function.
1. If the HTTP Header Variable REMOTE_USER is set, this user should be a valid logged on user. (Single Sign On functionality)
2. If the HTTP Header Variable is not set, the LOGIN-Page should appear. (local user Administration)
3. The user/password combination from the login page should be validated by my own authentication function I think I have to create a sentry-Function, which is a combination of the sentry-functions which are used in the schemes "custom" and "HTTP Header Variable". I tried to find an implementation of these functions in the APEX_040200 database scheme, but without success.

I have a tabular form with a few columns. THey are ID, date1, date2 and task_name. The task_name is a drop down list of tasks. Upon selecting a specific task, I want the date1 and/or date2 columns to become read only (voided out) so users cannot enter in data. I am working with a tabular form, so I figured I need a javascript function to handle the logic and to call the function in the html elements of the column in the apex environment. This will need to happen dynamically (on click) before the page is submitted. I am more lost/confused on syntax. I know I will need to know the actual column name (coo1, coo2, something like that) of my columns that I will be refering to when I use javascript.

I have a report which comes from a table-function. This produces hundreds of lines of output which the user would like to be able to select and then export just the subset of lines.Looking at the Forum's (this article and this one) this seems possible if you are working with a table where you can re-query the original dataset with just a specific rowset required however as the table-function is generating output on the fly it is hard to rerun the query to reselect the same output for redisplay. Also most of the reports are working with interactive reports - whilst this is just static output. Is there a way to redisplay the information which has already been shown in an filtered way with check boxes?Is there then a way to have hidden fields which are not shown when the check boxes are selected but which can be shown in the "filtered" view? I am using Apex 4.0 at the moment on an Oracle 10g instance.

I am not familiar with form with report in APEX. I have a lot of forms with reports that was created before, but they have only create buttons. Now I need to add edit and delete buttons. I wish I do not have to recreate forms with reports. But when I tried to add delete function by comparing a form with delete button created by APEX, but it does not work. the delete button does not react at all.
setting is as follows:
button style: template based button
button template: Button
button type: normal
action: redirect to URL
execute validation: NO
URL target: javascript:apex.confirm(htmldb_delete_message,'DELETE');
database action: SQL delete action
condition type: value of item / column in expression1 is not null
expression1: P2172_ALIAS_ID
I also enable the delete in the process of :"Process Row of SOR_ALIAS"
If I set action of delete button as submit page, I can delete the row, but no standard popup warning,

I have just created the basic employee information form in which i upload the photograph of the employee. The photograph gets uploaded but it does not display properly. I have already referred the sample database application to display the image. Moreover, i have followed the same steps as it is used to display the product image in that application. Still i am unable to get result. I am getting following output:
<img src="apex_util.get_blob_file?a=35682&s=101496289174102&p=15&d=10639237623242912156&i=10639236703270912154&p_pk1=21&p_pk2=&p_ck=FCA12832591A1C706D76FDD589E551A2" />

1 - i want to ask few things as i m new to apex, i am using apex 4.1, and created 3 select list and a button in selecting of parameter,
1 select list : select area
2 select list: select product
3- select list - size of the product
i want to generate Ids for the following. for that i created query for INSERTING RECORD FROM ONE TABLE TO ANOTHER , generation the ids when button pressed "Generate" after selecting parameters,
Now where i call that QUERY on button ? because when i create button its gives me option to submit, defined dynamic action, etc, where i call the function name id_generation when button pressed?
2- second thing i created tabular " select user_id, product_name, product_type from product".
By default check box list are create delete submit button are created, first when i insert record it saves that was fine, e.g i entered 50 records and afterward i want to update only one record, e.g there is a record product name = box, if i change it to box small and click submit then it saves all the page means all 50 records,
I want to submit only that record that i changed, for that i use the logic that only those records should be updated which are checked but the user. how will i do this ?

I am currently using APEX 4.1 on oracle 11g XE.
By now I only know one way to delete text messages (globalization) and that is click them one-by-one and hitting the delete button.
To delete 100 messages this is really a pain, so I thought, there must be a way to multi-delete them, or just flush them out!
I searched all over the internet but I can't seem to find a way.
Is there a way to delete all text messages? For example by using wwv_flow_api or any other way?

On a tabular form I have 50 columns each an input box , (basically 50 weeks of the year)
in these boxes I want to make them numbers only and max length 2
currently I have in the ELEMENT ATTRIBUTES for each column
OnFocus="javascript:this.maxLength=2"; onKeyPress="return numbersonly(this,event)";
( I have a function called numbers only in page 0 )
what I would like to do , to make it more maintainable is to remove all the calls in the element attributes of each column
and put it in 2 dynamic actions how would I go about this ?
I have tried using jquery selector of input:text to call javascript code on both events , Get focus and Key Press for every text box but its not working .

from TA_FEATURES t2
where t2.FCODE = t1.FCODE
)
It returns Error report:
