Inline View Subquery
 
08:31
Inline View Subquery merupakan jenis dari subquery yang menempatkan subquery sebagai atribut atau objek dalam sebuah query. Misalkan diketahui sebuah query yang memiliki klausa JOIN sebagai berikut: SELECT m.nim, nama, COUNT(kodemk) jmlmk FROM mahasiswa m LEFT JOIN nilai n ON m.nim=n.nim GROUP BY m.nim, nama; dengan menggunakan subquery maka JOIN bisa dihilangkan, querynya sebagai berikut: SELECT nim, nama, (SELECT COUNT(kodemk) FROM nilai n WHERE m.nim=n.nim) jmlmk FROM mahasiswa m;

Analytical Functions in oracle explained with real examples
 
25:24
This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

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?
