############################################################################### # # Basic test to confirm the correct behavior when executing SAVEPOINT, # ROLLBACK TO and RELEASE SAVEPOINT commands # # The execution of SELECT guarantee the correct values on TABLE after process # SAVEPOINT commands # # Test: # 0. Create a table to insert data # 1. Create a transaction and insert values and savepoints (S1, S2, S3, S4) # 2. Release savepoint S4 # 4. Rollback to a savepoint S2 and verify that savepoint S3 disappeared # 5. Insert more values and rollback to S2 to verify that rollback don't # remove savepoint # 6. Check the multitable update on 'rollback to savepoint' is proper. # 7.
