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/

What is a VIEW in Oracle? An Oracle VIEW, in essence, is a virtual table that does not physically exist. Rather, it is created by a query joining one or more tables. Create VIEW Syntax The syntax for the CREATE VIEW Statement in Oracle/PLSQL is: CREATE VIEW view_name AS SELECT columns FROM tables [WHERE conditions]; view_name The name of the Oracle VIEW that you wish to create. WHERE conditions Optional. The conditions that must be met for the records to be included in the VIEW. Example Here is an example of how to use the Oracle CREATE VIEW: CREATE VIEW sup_orders AS SELECT suppliers.supplier_id, orders.quantity, orders.price FROM suppliers INNER JOIN orders ON suppliers.supplier_id = orders.supplier_id WHERE suppliers.supplier_name = 'Microsoft'; This Oracle CREATE VIEW example would create a virtual table based on the result set of the SELECT statement. You can now query the Oracle VIEW as follows: SELECT * FROM sup_orders; Update VIEW You can modify the definition of an Oracle VIEW without dropping it by using the Oracle CREATE OR REPLACE VIEW Statement. Syntax The syntax for the CREATE OR REPLACE VIEW Statement in Oracle/PLSQL is: CREATE OR REPLACE VIEW view_name AS SELECT columns FROM table WHERE conditions; view_name The name of the Oracle VIEW that you wish to create or replace. Example Here is an example of how you would use the Oracle CREATE OR REPLACE VIEW Statement: CREATE or REPLACE VIEW sup_orders AS SELECT suppliers.supplier_id, orders.quantity, orders.price FROM suppliers INNER JOIN orders ON suppliers.supplier_id = orders.supplier_id WHERE suppliers.supplier_name = 'Apple'; This Oracle CREATE OR REPLACE VIEW example would update the definition of the Oracle VIEW called sup_orders without dropping it. If the Oracle VIEW did not yet exist, the VIEW would merely be created for the first time. Drop VIEW Once an Oracle VIEW has been created, you can drop it with the Oracle DROP VIEW Statement. Syntax The syntax for the DROP VIEW Statement in Oracle/PLSQL is: DROP VIEW view_name; view_name The name of the view that you wish to drop. Example Here is an example of how to use the Oracle DROP VIEW Statement: DROP VIEW sup_orders; This Oracle DROP VIEW example would drop/delete the Oracle VIEW called sup_orders. Frequently Asked Questions Question: Can you update the data in an Oracle VIEW? Answer: A VIEW in Oracle is created by joining one or more tables. When you update record(s) in a VIEW, it updates the records in the underlying tables that make up the View. So, yes, you can update the data in an Oracle VIEW providing you have the proper privileges to the underlying Oracle tables. Question: Does the Oracle View exist if the table is dropped from the database? Answer: Yes, in Oracle, the VIEW continues to exist even after one of the tables (that the Oracle VIEW is based on) is dropped from the database. However, if you try to query the Oracle VIEW after the table has been dropped, you will receive a message indicating that the Oracle VIEW has errors. If you recreate the table (the table that you had dropped), the Oracle VIEW will again be fine.

There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

Connecting SQL Tables and data in Excel spreadsheets
 
03:08
For more videos on technology, visit http://www.Techytube.com By [email protected] SQL server is a powerful database platform, this means that it can also be complex to understand and work with. However the major users of the data in the database are still a non-technical business user. A key problem that most business users face when it comes to working with SQL Server is the dependency on an IT professional to query and return the data in a CSV format or Excel sheet. With the ability of MS Excel to be able to connect to SQL Server via the ODBC Drivers allows users to work with SQL tables within the familiar Excel User interface. This approach allows users to be productive with SQL Server without having to know Transact SQL. The feature set provided with MS Excel and newer versions of SQL allow business users to do much more than just query the database. These include the ability to query and view data in pivot format for large data sets using power pivot. Perform ad hoc calculations to underlying data and create models that are specific to their business case using the powerful DAX language. Embedding reports in SharePoint services using PowerPivot. Working with Excel is one of the most powerful ways that end users can work with MS SQL Server to deliver results faster and improve productivity.
