Hi Experts,
As we have various types of RI in teradata like Soft RI,application RI ,Batch RI,Explicit RI, Standard RI..
I know that Soft RI allows the Optimizer to utilize join elimination in the generated
plan with out enforcement performed implicitly during the execution of the insert, delete, or update..
On the other hand ,other RI's allows the Optimzer to utilize the Join elimination with enforcemenit performed explicilty during Insert/Update & Deletes.
I am not sure what are the difference between Application RI,Batch RI,explicit & standard RI as they all fall in the same category.
Can any one please elaborate more on this?
Cheers!
Nishant
