Update array value into database

Hi, I would like to enquire if there is any way to update an array in the database.
As an example, i have an array which contain the value of the operating hour. I am able to insert the array value successfully into the database. Now i have problem to update the database, for these arrays.
Any suggestion will be very much appreciated.
Thank you in advance.

fizRiani wrote:
the field type is a string arrayReally? Have never seen that before in databases. Aren't you confusing database field type with Java object type?
the actual data represent the different operating hour that has to be inserted and updated to the database.I would rather use a chain table. Read on about database normalization.

Please show me where to put my codes to edit(edit directly on table control fields) and update my table control(using the 'save' button)?

Hi,
You have to put the following code in the PBO of screen 1000.This code would make the fields editable to make changes in the table control fields directly.
Here there are 3 transactions.For create and change transactions, the fields will be in editable mode and for display transaction,they will be non editable mode.
DESCRIBE TABLE tb_line LINES lin.    " tb_line is the name of the internal table for the table control
tcl_item-lines = lin.                             '' lin hold the number of lines of the internal table
CASE sy-tcode.
    WHEN 'ZCREATE09' OR 'ZCHANGE09'.
***Checking if the table control is empty or not***
      IF lin NE 0.
        LOOP AT SCREEN.
***To make the screen editable****
          screen-input = 1.
        ENDLOOP.
      ELSE.
        LOOP AT SCREEN.
          IF screen-name CS 'TB_LINE'.
****To make the screen non-editable if no values are present in the
***table control****
            screen-input = 0.
            MODIFY SCREEN.
          ENDIF.
        ENDLOOP.
      ENDIF.
Once the fields are edited and the save button is pressed,the entered values have to be populated into the Z tables.The code has to written in the PAI of the screen 1000.Here the values from the work area of the internal table are moved into the Z Table. The code will be.
LOOP AT tb_line.
    ztm09_ekpo-ebeln = ztm09_ekko-ebeln. "ztm09_ekko and ztm09_ekpo are the names of the Z Tables.
    ztm09_ekpo-ebelp = tb_line-ebelp.
    ztm09_ekpo-matnr = tb_line-matnr.
    ztm09_ekpo-menge = tb_line-menge.
    ztm09_ekpo-meins = tb_line-meins.
    ztm09_ekpo-netpr = tb_line-netpr.
    ztm09_ekpo-waers = tb_line-waers.
*****Update the entries into item table*****
    MODIFY ztm09_ekpo.

Updating tableview back into database table

I am trying to display a recordset from mysql database table into a tableview in javafx. Maybe let's say get all records where invoice number is 101 i n the master table from the child records in the child table.(This is a typical master detail scenario.) After this I update the tableview add, delete, edit some records AND then I want to save this Tableview or rather update it back, synchronise into the database table.
I request you to kindly help with sample code or any guidelines that will help me in this objective.

Here is the tutorial of tableView : http://docs.oracle.com/javafx/2/ui_controls/table-view.htm
You can use the Java Class that mapped the database for ObservableList. Get all the record in the database and cover it to the java object. Then add them to the ObservableList to show on TableView. After add, update, edit,... Get the item in the ObservableList and update back to your database.
I can't tell in detail. You should try this tutorial and if there are any more Specific Issue you can post another question here.

How to Insert check box value into database column

Hi All,
I had checkbox group in a region which is using an LOV......and having 18 items in that lov.
i.e. Total 18 checkboxes in Total. User has to select only 2 checkboxes from that 18.
I created two columns for storing two values of checkboxes. How to insert two selectives in two columns.........Moreover, How to give the query i.e. how to know which values are selected.
Please Help me in achieving this. apart from the two columns (Focus1,Focus2) .......One more column(l_spo_val) is there which is a foreign key.
My Insert Statement is like this:
INSERT INTO SPO_RESEARCH_FOCUS VALUES(l_spo_val
,:P4_RESEARCH_LIST_1
,:P4_RESEARCH_LIST_2);
Please narrate the code if possible.
Thanks,
Sekhar.

Hi Denes,
I saw the example in your workspace and it is the same what exactly i want and instead of storing in one column i want to store the two selected values into two different columns. Also i need to restrict the selection of checkboxes upto 2 only. So If the user tries to select the third check box it doesnt have to accept.
Even I am ready to change my table as according to your example i.e. creating only one column. Store the values of selection into that column.
I was unable to see how u wrote the logic (Code) for your example in your workspace. It helps alot if you provide me the code for that example(Multi Checkbox One Column).
I was facinated after watching your examples in your workspace and am very much interested to know more about Apex.
Please help me insolving this as it is long pending issue for my requirement.
Thanks a lot again,
Sekhar.

Send Email and automatically save new value into database

Hi,
I think this is a very unique problem, hope that anyone could help me. I tried to send email notification using pl/sql block (check_delay) as below. Please focus to this section first, from the pl/sql:
Problem 1
--> if emp_rec.OVERDUE_AMOUNT_PAID is not null then
dbms_output.put_line('emp_rec.payment_progress_id ' || emp_rec.payment_progress_id || crlf);
select c.PAYMENT_PROGRESS into payment_progress from credit_sales c where c.PAYMENT_PROGRESS_ID = emp_rec.payment_progress_id;
payment_ratio := (payment_progress/emp_rec.invoice_amount);
dbms_output.put_line('count ratio progress payment to invoice amount ' || payment_ratio || crlf);
dbms_output.put_line('payment progress ' || payment_progress || crlf);
Here, sql checks whether overdue amount is being paid in progress from payment_overdue table..then creates variables for ratio(payment_ratio) and progress payment amount(payment_progress). After that if payment_ratio < 0.1 it must sends email notification to customer_id and customer_representative_id. However, it does NOT send notification to
customer_id! How do I amend the code so that customer_id will get the notification too?
Problem 2
In problem 2, please focus to :
-->if emp_rec.OVERDUE_AMOUNT_PAID is null then
If customer does not pay any amount, sql will first checks whether delay between scheduled payment date and current system is more than 3 days..
dbms_output.put_line('count days delay ' || round(sysdate - to_date(emp_rec.scheduled_payment_date)) || crlf || crlf);
if round(sysdate - to_date(emp_rec.scheduled_payment_date)) >3 then
After that, sql will counts how many times customer delays. If first time, the notification will count notification as number 1..and update remark column with the message and count value as below..
select count(a.payment_overdue_id) as count into count from payment_overdue a where a.customer_id = emp_rec.CUSTOMER_ID and a.invoice_no = emp_rec.invoice_no;
     dbms_output.put_line('update remark : '||emp_rec.remark);
update PAYMENT_OVERDUE set remark='Reminder notice no '||count where payment_overdue_id=emp_rec.payment_overdue_id;
Finally, notification to be sent to customer with the message format as below..
email_to:=emp_rec.customer_id||default_email;
select b.INVOICE_NO into invoice_no from INVOICE b where b.INVOICE_ID = emp_rec.INVOICE_ID;
subj:='Reminder to make payment for Invoice No '||invoice_no;
mesg:='Kindly make payment for your amount outstanding as per Invoice No '||invoice_no||'. Reminder notice no '||count;
dbms_output.put_line('Sending email to ' || email_to || ' subject: ' || subj);
e_mail_message(email_to,email_to,subj,mesg);
Unfortunately, no email notification being sent to customer with this message format.. Please help me to make customer to receive the notification with this format.
Kindly, thank you so much for you guys to help me solve these two problems, Problem 1 and Problem 2....
Thank you.

Hi BownieCross;
If you are using a local database file in your project the following may be the cause.
From Microsoft Documentation:
Issue:
"Every time I test my application and modify data, my changes are gone the next time I run my application."
Explanation:
The value of the Copy
to Output Directory property is Copy
if newer or Copy
always. The database in your output folder (the database that’s being modified when you test your application) is overwritten every
time that you build your project. For more information, see How
to: Manage Local Data Files in Your Project.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects
and unknown namespaces.

PreparedStatement.setFloat does not enter precise values into database

Hi
I have written a program where I am entering a record in to the
database using a prepared statement. The problem is for float datatypes, the
values being entered into the database are not rounded off. e.g. 1.65 is
being entered as 1.64999999
I am using the Sybase database and the driver is
com.sybase.jdbc2.jdbc.SybDriver.
If I replace PreparedStatement with Statement I am getting the precise values

to a stored procedure is not such a good idea and in fact it'is very
error prone.I meant passing parameters to an SP the way you do.

Problem in storing float value into database form C++ thru OCCI

Hi,
We are working on a project where numerical accuracy is crucial. As per our client required float data like 23.12345678 should be stoted and retrieved back accurately from C++ application.
We are using OCCI interface in C++ application. At the time of executing the query, we are moving the float value to host variable using setFloat() function. But oracle storing truncated or rounded value. Not exactly what we are proving.
Even we are not able store 22.22 also properly. In oracle column is defined as NUMERIC.
Its working fine, when we insert data from sql command promt by running a query. I guess we are missing some this in this process.
Please provide us any suggestions on this. It would be great if you can provide some sample code.
Regards,
Newbe

Updating array data in sql database

HI,
Im facing problems in updating array data in SQL database.
As of now, i am able to write an "insert" query and insert array data in an image datatype field. Im using image datatype because the array size is very big(around 80,000 x and y values).
Althoug inserting data is easy im unable to write a query to update this data.
Referring to the help of SQL server and Labview database connectivity toolkit, i came across a method of accessing image datatype....using textpointers, which are 16 bit binary values and using the WRITETEXT function instead of the UPDATE function.
but the problem im facing is that ive to pass the array as a 2d string array in the query as a result the updated array is retrieved in the form of a string a
nd not as an array. how do I get over this problem?

Hi Pavitra,
I'm not very clear on how you have inserted the data into your application, but I do know that when you call the UPDATETEXT or WRITETEXT function you use the TEXTPOINTERS to point to the first location of a 1d array. So, depending on how you've stored the data, you may have problems updating your data if you're looking at it as a 1d array instead of how you originally formatted it. If you are able to successfully access the data as a 1d array, you can use the database variant to data type vi and pass in a string array constant for the data type. This will convert the variant datatype into whatever you specify. You may have to index the row and column of the variant (you receive a 2d array of variant) first before you convert. If possible, can yo
u provide some more detail and maybe some example code of how you perform the insert and plan to do the update? I can probably give you a better solution if I know how you are formatting the data. Thanks!
