Oracle >> How to count the no of lines entered in a cell in table, because i want to restrict maximum line for a customer. friends kindly give some suggestions to execute this command with SQL and PL/SQL..
Create a validation on that page that runs when query exists.
Add this query changing P1_item with the name of your page item:
SELECT 1 from dual where length(:P1_item) - length(REPLACE(:P1_item, chr(10), ''))>10
Using this when you submit the page if there are more than 10 new lines in your page item the validation will popup an error.

I am using Apex 18.2. I created an interactive report which has 10 records. I try to add a logic that user can only be able to edit those records which recently created. User cannot do an edit to an old records. Means when user try to edit old records, it show as 'Display only' or not editable. Is there any way I can do that? Your help is really appreciated. Thanks
One option is to create your own link (icon, if you wish), just like another column in report's query.
As you're in SQL now, use any condition you want. Obviously, you have to be able to distinguish "old" from "new" rows. If we suppose that it is some DATE datatype column, so whatever is "yesterday" or older is considered to be "old", you'd
select case when datum < trunc(sysdate) then null
else 'Click here'
end as link,
empno,
ename
from emp
LINK column's type would be "link" (of course) and you'd make it navigate to another page in this application, pass values from here to there, etc.
I am trying to make an application completely manually without using any interactive reports or generated PL/SQL. Everything is working at the moment but I am stumped when it comes to the search bar and I can't find anything online to help me.
I have a classic report called 'Browse Job Vacancies' and a 'Search' button; I also have the 'C1_JOB_TITLE_ITEM' search bar and a page process called 'Search'.
In the process I have this code:
SELECT
JOB_CODE,
JOB_TITLE,
JOB_DESCRIPTION,
SITE_NAME,
EMAIL_ADDRESS,
TELEPHONE_NUMBER,
SALARY,
START_OF_PLACEMENT,
APPLICATION_METHOD,
APPLICATION_CLOSING_DATE
FROM JOB
WHERE upper(job_title) = upper(:C1_JOB_TITLE_ITEM);
I am getting this error:
ORA-06550: line 1, column 64: PLS-00428: an INTO clause is expected in this SELECT statement
So I created this code:
DECLARE temp_row char;
BEGIN
SELECT
JOB_CODE,
JOB_TITLE,
JOB_DESCRIPTION,
SITE_NAME,
EMAIL_ADDRESS,
TELEPHONE_NUMBER,
SALARY,
START_OF_PLACEMENT,
APPLICATION_METHOD,
APPLICATION_CLOSING_DATE
INTO temp_row
FROM JOB
WHERE job_title = :C1_JOB_TITLE_ITEM;
END;
Here I am getting this error:
ORA-06550: line 13, column 16: PL/SQL: ORA-00947: not enough values
I am completely stumped on what to do at this point so any help at all is greatly appreciated. Sorry if I'm not being detailed enough this is my first time writing in Stack Overflow.
(Editing because someone didn't think this was an answer.)
You say you have a page process. You don't need any sort of process for this. You should have a Region with the following properties (assuming 18.x):
Type = Classic Report
Source > Location = Local Database
Source > Type = SQL Query
Source > SQL Query > your query from your first block above
Apex will run the query and create a report based on it. Processes are for PL/SQL blocks that do something like populating data or manipulating the database in some way.
When you enter a keyword in your item and click your button (the button action should be Submit Page), Apex will populate C1_JOB_TITLE_ITEM in session state with the user's value, then use that in the bind variable when it re-generates the page.
1) Create a classic report with that SQL as the source code.
2) Set C1_JOB_TITLE_ITEM in Page Items To Submit attribute, just under region source.
3) Create the page item C1_JOB_TITLE_ITEM, as your search field.
4) Create a Dynamic Action on Change of that item, and refresh your classic report region. The timing of this refresh is up to you. Step 2 ensures the value you've typed in the browser is sent to the database for the purpose of re-running that query.
Do you have a function based index on upper(job_title)? Otherwise you may experience performance issues.
I'm trying to fill out various text fields on an apex application when I select a Reference Number in a select list.
When the page loads I'd like the text fields to be filled with the information from the database related to the reference number from the select list, however, I don't know how to do so. Any suggestions or help would be most appreciated!
As far as I understood the question:
user opens a page
there's a Select List item
user picks a value
you want to populate certain items on that page, based on a value user previously selected
If that's so, you'd use a dynamic action - create it on the Select List item, pick set value type.
[EDIT: How to do that?]
Scott's schema, DEPT table. Suppose that the select list item is P15_DEPTNO, while two other items are P15_LOC and P15_DNAME.
create a dynamic action on P15_DEPTNO
event: change
item: P15_DEPTNO
create its True action:
action: set value
type: SQL statement
select loc, dname
from dept
where deptno = :P15_DEPTNO
items to submit: P15_DEPTNO
affected elements: items P15_LOC, P15_DNAME
That's all.
I have a drop down select list (P2_ROLE). I want to generate the interactive grid based on the value that I select from the drop down.
I am trying to do that but the query is not returning any result in the grid. However, if I query it in the database, it returns me the result.
It looks like that it is not substituting the value from the dropdown into the IG query. But If I hard code the value, it gives me the results.
dropdown_IG issue
I also tried returning the value selected from the dropdown in the item : P2_SELECT_LIST_VALUE and then using it in the query. But it also doesn't work.
The query that I have used for my Interactive grid is :
Select USER_NAME
From WF_USER_ROLES
Where ROLE_NAME = :P2_SELECT_LIST_VALUE ; --using the value from new item
or
Select USER_NAME
From WF_USER_ROLES
Where ROLE_NAME = :P2_ROLE; -- using the value directly from Dropdown
After selecting the value in the dropdown, I am refreshing the IG region using dynamic action on change select list. But that also doesn't help. How can I do that ?
Select list returns two values: display and return. Its form is, for example,
select dname disp_val,
deptno ret_val
from dept;
Its return value is then used in interactive grid's query.
Also, in order to be able to use select list's value, it has to be stored in session state; if it is not, query won't work. The simplest option is to submit the page, and you can do that by setting that item's Page action on selection property to "Submit page". Doing so, your IG query:
Select USER_NAME
From WF_USER_ROLES
Where ROLE_NAME = :P2_ROLE
should work OK. If it still does not, create an example on apex.oracle.com, provide credentials so that we could have a look at what you did.
I am developping a web application in Oracle Application Express (Apex) technology.
I have a page where I can add a new record to a table called 'tz_tab'. That table has a column 'pos' which is one letter (single char) - 'Y' or 'N'. Now, i'd like to do something like this:
When post processing (== updating/inserting 'tz_tab') form on the page - check if 'pos' value is 'Y'
If so - update the rest of records in 'tz_tab' values to 'N'
I tried creating triggers on 'tz_table' but with no success.
Summing up, I need to have only one record with 'pos' value == 'T' in 'tz_tab'.
Is there any method to do this by APEX or should it be done with oracle triggers?
Thanks!
It sounds like you can achieve this by creating a PL/SQL process in your APEX page that will fire after submit. You should be able to check page items and perform an UPDATE statement as required.
You don't say how you're doing your processing in Apex, but you can create a page process that fires after your insert/update step with something like.
UPDATE tz_table SET pos = 'N' WHERE id != :ID_OF_THE_ITEM_JUST_UPDATED
