How To Create Workspace User in Oracle APEX

Leave a Comment

This article will describe about How To Create Workspace User in Oracle APEX. You will get one workspace when you are successfully register on Oracle APEX website ( On Oracle Application Express, all of your applications and data will be combined on 1 application workspace. This workspace will have a correlation with your database schema. One workspace will be mapped into one schema, but one schema might be used by several workspace.

Workspace can be analogically as a garage. On a garage there will be stored some tools, a vehicle or some furniture (chair, desk, etc.) or anything you want to place in it. Garage will be secured with a special door with a key. To enter the garage you must open the door with a correct key, without a correct key you will not be able to enter the garage. You may allow another person to enter the garage by giving the duplicate of the key.

Okay let we start to create a workspace user on Oracle APEX, here are the steps:
1.       Sign In into your existing workspace with your username and password

2.       Click on Manage Users and Groups option, it located on the right top of your Oracle APEX dashboard. Click on the head with dropdown menus (3rd from the right) and you will get the menu.

3.       Now you will be at “Manage Users and Groups” page. You will find existing users there. Click on Create User button (blue button) on the top right to start the process.

4.       Next on User Identification section you need to fill some information. Fill the desired username and your valid email address, these fields are mandatory. Next Click on Account Privileges tab.

5.       On Account Privileges section, you must choose some options. Choose the default Database Schema, decide whether the user is workspace administrator or not. The one thing for sure is you must choose the user as a developer to give the user access to be able to create some applications. Next click on the Password tab.

6.       On the Password tab, set your desired password. It must be unique password, consist of 8 character with combination of uppercase, lowercase, number and special character (e.g. *). Click on Create User blue button to complete the process.

7.       Now you will find new user you just created. To create another user, you can repeat the process by clicking the Create User Button.

8.       It’s time to check your new user. Sign out from existing user by clicking on Sign Out button under currently connected user (top right corner). Sign In with your new user on the Oracle Application Express Sign In form.

9.       If you are entering the correct username and password combinations you should be able to enter the Oracle Application Express dashboard as a developer.

That’s all for the process of HowTo Create Workspace User in Oracle APEX. Hope it’s clear enough for you to manage your workspace users.

 SQL Plus used for managing database Object on Oracle Database. For accessing SQL Plus you can use command prompt on Windows Operating System. Open CMD from command prompt then type:


You can login using your own defined username by following instructions on . Form example if you create user with name mi123 with user mi123 you can type the following syntax:

SQLPLUS mi123/mi123;

The INSERT command has a rule value (must be the value) must have the same number, data type and sequence with the attribute (column name) of the table to which it belongs. If the structure of the destination table is known for certain amount, data type and sequence then the column name / attribute can be excluded.

INSERT INTO <tabel_name> (<attribut(es)>)
VALUES (<value(s)>);

INSERT INTO tstudent (sid, name, phone) VALUES (101, ’One’, 111111);

Explanations :
INSERT INTO tstudent -> Perform the insert command into the tstudent table.

(sidm name, phone) -> Target attributes to do the addition of data, the order of attributes really need to be considered.

VALUES (101, ‘One’, 111111) -> The value 101 is inputted into the SID attribute, the value 'One' is inputted into the name attribute, the value '111111' is inputted into the phone attribute. These three values generate a new row of data in the table.

; (titik koma) -> Denotes the end of a SQL command.

Now please fill in the following data into the TSTUDENT table by using the INSERT command like the example above:


Thus one uses the INSERT command on DML. Explanation of other INSERT commands and other DML commands will be discussed in the next article.

Thank You, Bobsis.

Advanced Form Development (Nested Form with Tabs) on Oracle APEX

Leave a Comment

This article will discuss about advanced form development (nested form with tabs) on Oracle APEX. Here we’re going to create a process of submission that involves three forms where each form in on different tab. The goal is we will fill some data into form1 on tab1, after completed then we will fill some data into form2 on tab2 and then we will fill some data into form3 on tab3. Data will be correlated among all of those three  forms.
The development phases will be divided into three, that are ER Diagram creation, Mockup Diagram creation and then following with coding phase.
1.       ER Diagram Creation
This article will use following ER Diagram that has 3 Entity Sets (Mahasiswa, DetilMahasiswa and UKM).

2.       Mockup Diagram Creation
Here are the three mockup diagrams that we will create (Form1, Form2, Form3):

3.       Coding Phase
After we design an ER Diagram, now we are ready for entering the coding phase. Here are the steps:
1.       Create 3 tables based on ER Diagram
a.       Tabel TMAHASISWA {#nim,nama,jk}
b.       Tabel TDETILMAHASISWA {alamat1,alamat2,telp,email,@nim}
c.       Tabel TMHS_UKM {tahun,jabatan,@idukm,@nim}

2.       Create new Database Application with a blank page

3.       Edit Page 1, Add HTML region namely form1
a.       Add following items (P1_JK static select list)

b.       Add a Next button, action when clicked is Submit.
c.       Fill this code on PL/SQL Process name it as simpan_form1:
                INSERT INTO tmahasiswa(nim,nama,jk) VALUES(:P1_NIM,:P1_NAMA,:P1_JK);
                apex_application.g_print_success_message := 'Berhasil';

d.       Run the page, it should be look like this:

4.       Add new Blank Page
a.       Name it as Form2, Breadcrumb is enabled

b.       Choose Tab option enabled

c.       Finish the creation process the edit it. Add a HTML Region.
d.       Add following items on Form 2:

e.       Set P2_NAMA item with following descriptions:

f.        Add a button name it P2_PREV. Set the properties as follows:

g.       Add a button name it P2_NEXT, action when button clicked = Submit. Set the grid layout properties as follows:

h.       Create a PL/SQL Process name it as simpan_form2, assign it to P2_PREV button. Fill this code into source:
                INSERT INTO tdetilmahasiswa(alamat1,alamat2,telp,email,nim) VALUES(:P2_ALAMAT1,:P2_ALAMAT2,:P2_TELP,:P2_EMAIL,:P2_NIM);
i.         Run the Page, it should be look like this:

5.       On SQL Command, create stored function name it as cek_ukm
create or replace function cek_ukm(p1 in varchar2, p2 in number, p3 in number) return varchar2
                vukm VARCHAR2(8);
                hasil varchar2(128);
                select idukm into vukm from tmhs_ukm where idukm=p1 and nim=p2 and tahun=p3;
                select nama_ukm into hasil from tukm where id=vukm;
                return hasil;

6.       Create stored function name it as cek_jabatan
create or replace function cek_jabatan(p1 in varchar2, p2 in number, p3 in number) return varchar2
                hasil varchar2(128);
                select jabatan into hasil from tmhs_ukm where idukm=p1 and nim=p2 and tahun=p3;
                return hasil;

7.       Create new Blank Page
a.       Name it as Form3, Breadcrumb is activated

b.       Activate the Tab set

c.        Finish the page creation the edit it. Add new HTML region.
d.       Add following items:

e.       Set P3_NAMA item properties as follows:

f.         Add a report region, fill this SQL into the source:
select NVL(cek_ukm(id,nim,tahun),APEX_ITEM.SELECT_LIST_FROM_QUERY(1,NULL,'SELECT NAMA_UKM,ID FROM TUKM')) as ORG, NVL(cek_jabatan(id,nim,tahun),APEX_ITEM.TEXT(2)) as JBT
from tukm a
left outer join (select * from tmhs_ukm where nim=:P3_NIM and tahun= :P3_TAHUN) b on

Edit that region, go to Report Attributes

Edit column ORG and JBT, make sure the Column Attributes set to Display As Standard Report Column. Apply Changes.
g.       Add new button (P3_SIMPAN), action when button clicked=submit
h.       Create new PL/SQL Process name it as simpan_form3, assign to P3_SIMPAN button. Fill this code into the Source area:
 for i in 1..apex_application.g_f01.count loop
  IF apex_application.g_f01(i) <> '%null%' THEN
  insert into TMHS_UKM (tahun,jabatan,idukm,nim)
                values (:P3_TAHUN,apex_application.g_f02(i),apex_application.g_f01(i),:P3_NIM);
 end loop;
i.         Run the Page, it should be look like this:

The creation process has completed, now we’re going to try it.
1.       Check the TUKM table data

2.       Run the application, fill data on Form1 then click Next button

3.       Form2 will automatically shows along with Nama (Boby Siswanto). Fill data on Form2 then click on Next button

a.       Form3 will automatically shows, fill the text fields. Choose select list options on bellow area (Organisasi) and fill the Jabatan’s values. Click Simpan button.

b.       When the process is successful, success message will be shown:

c.       Check the TMAHASISWA table, new record with Boby Siswanto values will be inserted.
d.       Check the TMHS_UKM table, it should be contains some values:

That’s all for advanced form development (nested form with tabs) on Oracle APEX tutorial. You should be able to create one process divided into several forms.
