If I'm right then is there any way I can find out the diferrence between Query I wrote and Query sql executed!!No, it's not converting it to an inner join, it's already an inner join, just a different way of writing it. They're harder to read, easier to make mistakes with and impossible to convert to outer joins, but if you wish you can use themIn addition to these points, the type of join used in a query implies intent

SQL Server follows ANSI Entry SQL with regard to referential integrity between PrimaryKey and ForeignKey columns which requires the inserting, updating, and deleting of data in related tables to be restricted to values that preserve the integrity.

The second form of the query happens to find a plan using only nested loops outer joins early in the search process, and again the optimizer decides that plan is good enough. All three also happen to produce the same physical execution plan with the data set provided: As I mentioned in my answer to your previous question, queries that express exactly the same logical requirement will not always produce the same execution plan
