Submission of a form creating multiple rows in DB table

idm731Apr 11 2014 — edited Apr 13 2014

Hi All

I have created a new Apex application and have created a table with columns - USER_ID, ADDRESS, PHONE, CREATEDON etc

I want to read the USER_ID of the logged in user and populate this field on the form and populate the CREATEDON field with the system date. These two fields are hidden on the form.

Now when the user fills his address and phone on the form and clicks submit, 3 identical rows are inserted in the DB table. The values of logged in user and system date are successfully set.

To set the USER_ID field, I have inserted $APP_USER. in the default value section of the form. I am not able to understand, why Apex is inserting multiple rows even when the submit button is clicked once.

Please help.

it means ords can't establish connections to the database for the connection pool
is that ip address reachable from the machine ords is running on? Can it get to port 1521 on that machine? If not, this won't work

thanks jeff.
tnsping is ok, connect using sqlplus username/password@listener_name is ok.
sqlplus usename/passwod@ipaddress:1521/listener_name is ok
but,
ORDS seems like using jdbc:oracle:thin:@//ipaddress:1521/listener_name.
so i tryed that Sqlplus username/password@jdbc:oracle:thin:@//ipaddress:1521/listener_name. but. it is not working..
and i tried using Sqldeveloper 19.4 and 21.1 . ip and TNS both not working.
DB Server Version for above test for ORDS install is 19c.
but. case of 12C DB Server IS NO PROBLEM.

i don't know why??
please guide me.

SK.

You could add the following to your sqldeveloper.conf to change the language to English temporarily:

AddVMOption  -Duser.language=en

That would make your screenshots better readable to an international audience.

i tried ORDS install with English Windows.
before running ords install, i checked java version and sqlplus connection.

another install test.
SQLDeveloper 19.2 can connect to remote 19c DB as previous shown image.
