Oracle Application Express (Oracle APEX) is a rapid web application development tool which uses the Oracle Database. This article summarises the resources you need to use it effectively.
Application Express includes a list of built-in substitution strings. These can be used in HTML regions or blocks of PLSQL code. This article lists all the substitution strings.
This query will give you a basic report on the bytes used and bytes available in the Tablespaces within a particular schema. I have used it within Oracle APEX but it can be used elsewhere.
In APEX it is nice to disable a button once it has been clicked. This can help prevent users clicking the button twice. You have to paste a simple piece of JavaScript into the Button's properties.
Many standard APEX themes and templates contain a region where process success or failure messages are displayed. You can provide custom messages in this area using the apex_application package.
The Interactive Reports in Oracle Application Express (APEX) are extremely useful. If you need to tweak their styling but there are limited ways to do that from the interface. So how can it be done?
Within the APEX APEX_UTIL package there are a couple of useful procedures for setting and resetting Interactive Report filters. This allows you to manipulate IR filters programmatically within PLSQL.
When you delete records from a record set in Oracle Application Express using a Delete button it is best to give the user a chance to cancel. This can be easily achieved using a JavaScript popup box.
