    I'm working since 3 years as a developer and i thought I'm a Superman in development. But going through this video i can say that i got very much & best technical knowledge... We implements thousands of things from theory but doesn't know their technical definitions and basic. Thank you Manish Sir for this best content.
    I still remember my struggling days in Mumbai before 4 years ago and at that time too I was referring your videos on C#. At that time I even don't have a money to spend on the courses. But I took benifits from your RUclips channel. Today there are many channels on YT but at that time you was only one who were helping us... I must say that for all developers who come from middle & low class, you are super hero for all of us .... Thank You Sir!!

    end try
    begin catch
    rollback
    end catch
    Inner join = Matching records from both tables
    Left join = All records from table on left side of join and only matching records from right side table of join.
    Right join = All records from table on right side of join and only matching records from left side table of join.
    full outer join = all records from both tables are extracted and in case of non matching null is shown
    cross join = cartesian product, every record of left table is multiplied with right table

    Hello Sir, Thank you for the great video . its really helpful for Developers like me. I have a question? On Q13, you mentioned like Non-clustered index depends on Clustered index to locate the data. What if a table has No Clustered index (Or a primary key) ? I think in that case , data is stored in an unordered structure called heap and Non clustered index stores a pointer which refers to the heap storage. Please correct if i am wrong..
