Hi,

Could anyone please explain me the execution plan operators.
nested loop, merge loop and hash join

Out of this which one is best and worst and in what scenario these operators are used when execution plans are analysed for better performance. How to overcome explictly when there is performance bottlenecks if any.

Requesting for a detailed explanation on this topic.
