I have been working on SQL Server databases for more than 5 years and I was not aware of the difference between the On clause and Where clause when used with left join. Once I asked this question to our DBA (who has 10+ years of experience) and he said that there is some difference but he was not be able to explain the difference. Then I started exploring this topic myself and got some interesting observations of these two clauses when used with left join. So today I decided to share my knowledge so that everyone could benefit from my work.
