The video demonstrates what are the different types of joins and who they work in SQL. The tutorial is a little elaborate to make sure that you understand different kind of joins and where you should use which kind of join. The 5 Kind of joins explained are. 1. Inner join (Join or simple join) :- Rows that are common to both tables are returned as the output. 2. Left Outer join (Left join):- Returns all rows from the left table along with matching rows from the right table 3.Right Outer join (Right join):- Returns all rows from the right table along with matching rows from the left table 4.Full outer join (Full join) :- Returns all the records when there is a match in either left or right table. 5. Cartesian Join : (Join with no where condition)also known as a Cartesian product, is a join of every row of one table to every row of another table.

Subqueries in sql   Part 59
 
14:34
In this video we will discuss about subqueries in sql server. Let us understand subqueris with an example. Please create the required tables and insert sample data using the script below. Create Table tblProducts ( [Id] int identity primary key, [Name] nvarchar(50), [Description] nvarchar(250) ) Create Table tblProductSales ( Id int primary key identity, ProductId int foreign key references tblProducts(Id), UnitPrice int, QuantitySold int ) Insert into tblProducts values ('TV', '52 inch black color LCD TV') Insert into tblProducts values ('Laptop', 'Very thin black color acer laptop') Insert into tblProducts values ('Desktop', 'HP high performance desktop') Insert into tblProductSales values(3, 450, 5) Insert into tblProductSales values(2, 250, 7) Insert into tblProductSales values(3, 450, 4) Insert into tblProductSales values(3, 450, 9) Write a query to retrieve products that are not at all sold? This can be very easily achieved using subquery as shown below. Select [Id], [Name], [Description] from tblProducts where Id not in (Select Distinct ProductId from tblProductSales) Most of the times subqueries can be very easily replaced with joins. The above query is rewritten using joins and produces the same results. Select tblProducts.[Id], [Name], [Description] from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId where tblProductSales.ProductId IS NULL In this example, we have seen how to use a subquery in the where clause. Let us now discuss about using a sub query in the SELECT clause. Write a query to retrieve the NAME and TOTALQUANTITY sold, using a subquery. Select [Name], (Select SUM(QuantitySold) from tblProductSales where ProductId = tblProducts.Id) as TotalQuantity from tblProducts order by Name Query with an equivalent join that produces the same result. Select [Name], SUM(QuantitySold) as TotalQuantity from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId group by [Name] order by Name From these examples, it should be very clear that, a subquery is simply a select statement, that returns a single value and can be nested inside a SELECT, UPDATE, INSERT, or DELETE statement. It is also possible to nest a subquery inside another subquery. According to MSDN, subqueries can be nested upto 32 levels. Subqueries are always encolsed in paranthesis and are also called as inner queries, and the query containing the subquery is called as outer query. The columns from a table that is present only inside a subquery, cannot be used in the SELECT list of the outer query. Next Video: What to choose for performance?

Part 13 Sub Query in Sql in Hindi
 
03:15
What is subquery in SQL Server with examples? You can define a T-SQL subquery wherever an expression is permitted in a statement. For example, you can embed a subquery in the SELECT list of a SELECT statement, or include one in the search condition of the WHERE clause. ... NOTE: A subquery is sometimes referred to as an inner select or inner query. What is the use of subquery? A Subquery or Inner query or a Nested query is a query within another SQL query and embedded within the WHERE clause. A subquery is used to return data that will be used in the main query as a condition to further restrict the data to be retrieved. ... A subquery cannot be immediately enclosed in a set function. Which is better join or subquery? The good thing in sub-queries is that they are more readable than JOIN s: that's why most new SQL people prefer them; it is the easy way; but when it comes to performance, JOINS are better in most cases even though they are not hard to read too. ... a class of subqueries that can not be rewritten using joins.

IN VS EXISTS VS JOIN, performance
 
05:04
This video demonstrates the performance effects of using an exists clause instead of an IN clause, also it shows how we can update a simple sub query having an IN clause with an EXISTS or JOIN statement. It also shows that joining would consider the null data, where as an IN clause would neglect null values.

SQL для начинающих (DML): Объединение таблиц INNER JOIN / JOIN (MySql), Урок 13!
 
36:14
Декартовое произведение - это есть отношение двух и более отношений, таких что, каждый кортеж одного отношения сопоставляется с каждым кортежем другого отношения. Пусть будет две таблицы таблица ролей. 1, admin 2, user таблица юзеров 1, Ivan 2, Andrey 3, Nikita Тогда декартовое произведение этих двух отношений будет следующим: 1, Ivan, 1, admin 1, Ivan, 2, user 2, Andrey, 1, admin 2, Andrey, 2, user 3, Nikita, 1, admin 3, Nikita, 1, user Таким образом можно найти декартовое произведения трех и более отношений, где каждый кортеж сопоставляется с каждым кортежем остальных отношений. Добавим таблицу стран. 1, Украина 2, США 3, Германия 4, Россия 5, Китай И напишем декартовое произведение трех таблиц, роли, юзеры и страны. Т.к. у нас уже выше написано декартовое произведение юзеров и ролей, следовательно осталось сопоставить это отношение что получилось от юзеров и ролей с отношением стран: 1, Ivan, 1, admin, 1, Украина 1, Ivan, 1, admin, 2, США 1, Ivan, 1, admin, 3, Германия 1, Ivan, 1, admin, 4, Россия 1, Ivan, 1, admin, 5, Китай 1, Ivan, 2, user, 1, Украина 1, Ivan, 2, user, 2, США 1, Ivan, 2, user, 3, Германия 1, Ivan, 2, user, 4, Россия 1, Ivan, 2, user, 5, Китай 2, Andrey, 1, admin, 1, Украина 2, Andrey, 1, admin, 2, США 2, Andrey, 1, admin, 3, Германия 2, Andrey, 1, admin, 4, Россия 2, Andrey, 1, admin, 5, Китай 2, Andrey, 2, user, 1, Украина 2, Andrey, 2, user, 2, США 2, Andrey, 2, user, 3, Германия 2, Andrey, 2, user, 4, Россия 2, Andrey, 2, user, 5, Китай 3, Nikita, 1, admin, 1, Украина 3, Nikita, 1, admin, 2, США 3, Nikita, 1, admin, 3, Германия 3, Nikita, 1, admin, 4, Россия 3, Nikita, 1, admin, 5, Китай 3, Nikita, 1, user, 1, Украина 3, Nikita, 1, user, 2, США 3, Nikita, 1, user, 3, Германия 3, Nikita, 1, user, 4, Россия 3, Nikita, 1, user, 5, Китай В данном случае в таблицах нет никакой связи между друг другом, которые должны быть, именно по этим связям, а точнее когда отталкиваемся от них и приходим к так называемым ключам, в таком случае сразу становится понятным каким образом связаны сущьности друг с другом и как отобрать именно корректные записи с помощью SQL конструкции ON.

Part 9   Difference between inner join and left join
 
09:16
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/06/part-9-difference-between-inner-join.html This is one of the very common sql server interview question. Different JOINS in SQL Server are discussed in detail in Part 12 of SQL Server tutorial for beginners video series. Let's understand the difference with an example. INNER JOIN returns only the matching rows between the tables involved in the JOIN. Notice that, Pam employee record which does not have a matching DepartmentId in departments table is eliminated from the result-set. SELECT EmployeeName, DepartmentName FROM Employees INNER JOIN Departments ON Employees.DepartmentID = Departments.DepartmentID LEFT JOIN returns all rows from left table including non-matching rows. Notice that, Pam employee record which does not have a matching DepartmentId in departments table is also included in the result-set. SELECT EmployeeName, DepartmentName FROM Employees LEFT JOIN Departments ON Employees.DepartmentID = Departments.DepartmentID In general there could be several questions on JOINS in a sql server interview. If we understand the basics of JOINS properly, then answering any JOINS related questions should be a cakewalk. What is the difference between INNER JOIN and RIGHT JOIN INNER JOIN returns only the matching rows between the tables involved in the JOIN, where as RIGHT JOIN returns all the rows from the right table including the NON-MATCHING rows. What is the difference between INNER JOIN and FULL JOIN FULL JOIN returns all the rows from both the left and right tables including the NON-MATCHING rows. What is the Difference between INNER JOIN and JOIN There is no difference they are exactly the same. Similarly there is also no difference between LEFT JOIN and LEFT OUTER JOIN RIGHT JOIN and RIGHT OUTER JOIN FULL JOIN and FULL OUTER JOIN
