To avoid errors, the inner join or left join is utilised for self join. 2. Cross Join: With a cross join, we may join every row of both tables. It works in the same way as the cartesian product, which combines all the rows.
The CARTESIAN JOIN or CROSS JOIN returns the Cartesian product of two or more connected tables' sets of records. As a result, it translates to an inner join in which the join-condition evaluates to either True or False or when the join-condition is not included in the statement.
The cartesian product in SQL Server is actually a cross-join that returns all the data from all the tables given in the query: each row from the first table is coupled with all the rows from the second table. When there is no relationship defined between the two tables, this occurs.
ANSI-standard INNER, LEFT OUTER, RIGHT OUTER, FULL OUTER, and CROSS are the five forms of JOIN defined by SQL.
Inner Join / Simple Join.
Left Outer Join / Left Join.
Right Outer Join / Right Join.
Full Outer Join.
Very Good trainer

Not too much interactive
Well Explained in Every Chapters..
GAJANAN DIGAMBAR MODE
very easy to understand SQL its was dream to learn SQL. Thanx for Learnvern
Why you didn't teach/learn how to write select query, even you shared 15 question for practice :(
I have found the course to be interesting with plenty of valuable information provided as part of the course and through interaction with fellow teachers and trainers from a wide range of disciplines
