Hi
The following are preventing parallel execution as far as I know:
Scalar parameters or variables used within procedure
SQL not assigned to variable
Has imperative and loop logic
Has DDL operations
operations that serialize (CASE )
In the following example temp1 and temp 2 can run parallel with Intra-Query Parallelism as well? temp3 will need the result of temp1 and temp2 so I quess no Inter-query Parallelism but what about Intra-Query Parallelism,in this point does HANA drop from the parallelization phase or temp 3 will be also run parallel just had to wait the result of temp1 and temp2?
What about itab_all_bp this will not run Intra-Query Parallelismbecause of the Case?
What are the other commands which serialize other than the Case?
Waiting for your valuable input.
