one) I ran SQL Tuning Advisor on a selected question as well as optimizer arrived up with the better execution plan for that query. The proposed program from the optimizer was with parallel execution, and when this parallel execution strategy was enabled for that query the optimizer calculated the DOP really significant and the query ran with higher parallelism, then the accessible cores over the method. In this type of scenario how to embed the hints manually to make sure that we can easily move the hints with fewer DOP.

7.Saved course of action returns generally integer benefit by default zero. wherever as purpose return type may very well be scalar or desk or desk values
