SQL Filter criteria in join criteria or where clause which is more efficient

Question

I have a relatively simple query joining two tables. The \"Where\" criteria can be expressed either in the join criteria or as a where clause. I\'m wondering which is more

Answer 1

One thing I want to say finally as I notified, before that.. Both ways may give the same performance or using the criteria at Where clause may be little faster as found in some answers..

But I identified one difference, you can use for your logical needs..

1. Using the criteria at ON clause will not filter/skip the rows to select instead the join columns would be null based on the conditions

2. Using the criteria at Where clause may filter/skip the rows at the entire results
