We can create authorization schemes to control access to a page in Oracle Apex. Below are more details:
Page Access Control in Oracle Apex Using Authorization Scheme
To control access over a page, you need a table where you can store the data for the users having access to specific pages. For this, I have written a detailed post User Access Control in Oracle Apex, you can check this for a better understanding.
Create a Table to Store User Acess Information
Here, I am giving below a simple table structure for this example:
Create Table user_access (record_id number primary key, user_id number, page_id number);
Insert Records into user_access Table
We will insert a record to specify that the user (with user_id 1) having the access to page number 5:
Insert into user_access (record_id, user_id, page_id) values (1001, 1, 5); Commit;
Create an Authorization Scheme
As of now, we have created the table and inserted a record. And now we can create an authorization scheme to control access to page number 5 in Oracle Apex. Below are the steps:
- Click on the Shared Components > Authorization Schemes then click on the Create button.
- Then in the next step, choose From Scratch radio button and click on the Next button.
- In the next step, specify the name for the scheme, for example, page_5_access.
- Select scheme type as Exists SQL query.
- And for SQL query, specify the following query:
Select null from user_access where user_id = :yourAppUserId and page_id = 5;
- Then specify the error message for the error message field as "You have no access to this page!".
- Then click on the Create Authorization Scheme button.
- Now go to page number 5 and in the property palette > Security, select the Authorization scheme page_5_access.
- Save the changes.
And it is done. Now you can run the page to test for the user with user_id 1 and for the other users as well.
