I am using oracle forms 10g.
I have used key-enter trigger.
I have created 3 text fields in which 2 are for inputs and 1 for result.
i want show addition of 2 i/p in result field.
I have used key-trigger for addition but when i pressed Enter key it doesn't works.
If you want a calculation to be done whenever either of your two input fields are changed, I suggest you put your code in WHEN-VALIDATE-ITEM triggers, one on each input field.

I have a report that requires 3 parameters, all 3 has q query to pre populate them using a dataset for each, so the under their properties the available values is selected with the query. Default were also set to use the same query. This work fine.
My problem is when the user of the report wanted to enter the values themselves rather than going into the list populated by the query. Users know the value that they wanted to enter so it's faster for them to enter rather than select. SSRS report seems not to give you the ability to enter if you have set the available values and default values for some reason. Is their a way to go around this please?
Many thanks.
There is one straight forward way to use comma separated multi value parameter rather than list where user enters input.
Below link explains in detail, but I am quite sure you do not want to stick to below solution.
https://www.mssqltips.com/sqlservertip/3479/how-to-use-a-multi-valued-comma-delimited-input-parameter-for-an-ssrs-report/
Another thing you could do is keep your multi value parameter as list as it is and create a text input parameter.
Now if user want to simply choose from list fair enough you will have to handle second parameter as null because user chose from list.
Then on your dataset check and apply filter as 2nd parameter value as not null.
Same goes if user does text input then multi value parameter as not null.
I want to access the contents of an Interactive grid with PLSQL. The only thing similiar is the
"Save Interactive Grid Data / Interactive Grid Automatic Row Processing (DML)" process that works on a per row basis.
I would like access the grid with PLSQL in a dynamic action, set a value X e.g. in row 1 column A and use this value X
to complete row 1 column B with a value that I get from the database using value X as input.
Is this possible or is the grid only accessible in javascript?
Yes, you can create a dynamic action that does an Ajax call to run some PL/SQL. You just need the correct triggering element and return conditions.
I'm not quite sure what you're trying to do. This is based off a user's action? Otherwise, why not just use the PL/SQL before you generate the grid?
So I'm somewhat new to access 2013, anyways, I've created a form in access 2013 based directly off a table, so no queries involved if that matters, and what I'm trying to do is just have a text box that updates the total value of 3 different fields as they're entered.
right now it's just a plain-text box, the control source is "=[Search Cost]+[Update Cost]+[Copy Cost]", and if I close the form entirely and reopen the record it updates the text box with the total for all three, but the customer wants it to update in real time. Any suggestions?
I just tried your scenario in Access 2013 on a simple form and it updated for me in real time as I entered values. However, that was because each of the three fields values had a Default Value of 0 in my test table.
So I suspect this is not updating for you in real time because one or more of those values is null while you are entering data in the form. Access doesn't know what [Some field value]+Null should be (it's an unknown thing) so it won't display a calculated value in real time on your form until you provide a value for each of the three fields.
So how can you get around this?
You can add a Default Value of 0 or some other value to each of the three fields at the table level.
Or you could modify your form expression to use the NZ function which will convert any null values to zero. So use this expression:
=Nz([Search Cost])+Nz([Update Cost])+Nz([Copy Cost])
Either of those options should achieve your end goal I believe. They did in my quick tests.
I have a report that is listing students and I want a column to edit a student. I've done so by following this answer:
How do you add an edit button to each row in a report in Oracle APEX?
However, I can only seem to pass 3 items and there's no option to add more. I took a screenshot to explain more:
I need to pass 8 values, how can I do that?
Thanks!
Normally, for this you would only pass the Primary Key columns (here looks like #RECORD_NUMBER# only). The page that you send the person to would then load the form based on the primary key lookup only. If multiple users were using this application, you would want the edit form to always retrieve the current values of the database, not what happened to be on the screen when a particular person ran a certain report.
Change the Target type to URL.
Apex will format what to already have into a URL text field which magically appears between Tem3 and Page Checksum.
All you need to do is to add your new items and values in the appropriate places in the URL.
I found a workaround, at least it was useful to my scenario.
I have an IR page, query returns 4 columns, lets say: ID, DESCRIPTION, SOME_NUMBER,SOME_NUMBER2.
ID NUMBER(9), DESCRIPTION VARCHAR2(30), SOME_NUMBER NUMBER(1), SOME_NUMBER2 NUMBER(3).
What I did was, to setup items this way:
P11_ITEM1-->#ID#
P11_ITEM2-->#DESCRIPTION#
P11_ITEM3-->#SOME_NUMBER##SOME_NUMBER2#
Previous data have been sent to page 11.
In page 11, all items are display only items.
And P11_ITEM3 actually received two concatenated values.
For example, the calling page has columns SOME_NUMER=4 and SOME_NUMBER2=150
so, in pag1 11, P11_ITEM3 shows 4150
In page 11 I created a Before Footer process (pl/sql expression)
to set up new items, for example P11_N1 as source SUBSTR(P11_ITEM3,1,1)
and item P11_N2 as source SUBSTR(P11_ITEM3,2,3)
So, I had those items with corresponding values from the calling IR page.
The reason I did not pass the primary key only for new lookup access, is because i do not want to stress database performing new queries since all data are already loaded into page items. I've been an oracle DBA for twenty years and I know there is no need to re execute queries if you already have the information somewhere else.
These workarounds are not very useful for a product that bills itself as a RAD tool.
Just include a single quoted word in the select statement (Select col1, 'Randomword', col2 from table 1;)
Then define that column as a link and bingo! More items than 3 to select.
I have to create a birt report with user input parameters. It is something like when the para
meter is left blank it should fetch all values from a table otherwise when the user inputs the students roll no.,the corresponding data should be fetched. Can this be done through Birt report? If yes, then please suggest a way.
Thanks!
Yes, you can do that. If the parameter is optional you can't use the Dataset Parameter (with a ? in your query), because it will be null. Instead you have to modify your query using JavaScript.
Create a Report Parameter like usual, in this case 'stud_no'. Then add a comment in your SQL that you are reasonably sure is unique, I use something like --$stud_no$, wherever you want your clause inserted.
Then add a script like this to your Data Set, in beforeOpen:
if (params["stud_no"].value){
this.queryText = this.queryText.replace("--$stud_no$", "and stud_no = " + params["stud_no"]);
}
This replaces the comment with the clause when the parameter has a value. You can use regex in the search string, and then you can also insert it multiple places if you want.
Create your paremater using a like statement
where students_roll_no like ?
Create your report paramater using as a text box, with a defualt value of %
Because the percent '%' is the SQL wildcard, it returns all values. If the user enters a Student Roll number, it returns only that record. Additionally the user can enter 0500% and get all the records that begin 0500.
