Re: Updating PLSQL Table

It's an array variable in PL/SQL, not a database table. Although it can be cast to appear as a relational table for querying, you use the PL/SQL assignment, bulk collect etc syntax to set values.

btw you don't need the explicit CAST in recent Oracle versions - TABLE(collection_name) will generally do it.
