Undocumented option for Static List of Values

Posted on by

Did you know that the STATIC and STATIC2 keyword used to define Static List of Values for Oracle Application Express (APEX) contains an undocumented option?

The online help documents the usage with 

STATIC[2]:Display Value[;Return Value],Display Value[;Return Value]

But what to do if one of your values contains the semi colon or the comma in the text? You will get a problem with the predefined separators!

In such a case you can use

STATIC[2](lov-entries-sep,display-return-sep) :D isplay Value[<display-return-sep>Return Value]
<lov-entries-sep>Display Value[<display-return-sep>Return Value]

For example: 

STATIC2(~,*):Cat, Dog*1~Nemo, Shark*2

Update: In Oracle APEX 3.1.1 there will be a new debug mode called REMOTE to enable remove debugging in Oracle APEX without having to modify the application. See the related posting on the OTN Forum.
