Usage of RDB-List method for querying Internal Class Instances
I was going through the Online Help System and under Working with PegaRULES Database, I came across the following:
"You can also use Connect SQL rules to search the database, but this is not recommended except in unusual situations."
I am trying to understand why usage of RDB-List is not recommended over Obj-Browse for filtering out Internal Class Instances. Is it only because Obj-Browse will generate a well-structured query internally or is there some other technical reason? Also can you cite one 'unusual situation' where Obj-Browse method is not usable but RDB-List is? A simple comparison over RDB-List and Obj-Browse methods is appreciated.
