Oracle APEX Tips & Techniques

In Oracle APEX, validating Interactive Grid (IG) data at row level, is easy and straight forward. You just need to select "Editable Region" for the validation and then you can use IG column values using :COLUMN_NAME syntax in SQL and PL/SQL code. However, if you want to create a validation at table level or validation which uses multiple rows data, then it becomes tricky. Let's consider a simple example of budget planning, where you can allocate percentage for each category, like 10% for healthcare, 10% for education etc. Here, we need to implement a simple table level validation to ensure total allocation % does not exceed 100. Please refer  Interactive Grid - Client Side Aggregate Validations  for implementing this validation entirely on client side. You can use technique explained below for more complex validations that can't be done on client side (checking data from multiple tables, number of rows in IG are more than 50) Before jumping into the implemen

Friendly URLs! It's been one of the most wanted feature in APEX from very initial days. It's one of the main complaints we hear from customers, especially for websites which are open for public. There are several benefits of having a friendly URL besides better user experience. Finally, the wait is over! APEX team has implemented this feature, probably in the most simplest way possible (for APEX developers). Big Kudos to the APEX Team. All you need to do is, just turn on a flag in application properties. Yes, you read it right.. Now, after enabling this flag, all APEX URLs will switch to new friendly URLs New URL Format: Example link - https://apex.oracle.com/pls/apex/hari/r/demo_app/home?session=714815362925554 Part-1:  https://apex.oracle.com/pls/apex/ - Host details, there is no change here Part-2: /hari/r -  Here hari  is work-space path prefix and  r  stands for router. You can modify "Path Prefix" at "Workspace Administration
