SQL View
SQL is a standard Structured query language for storing, manipulating and retrieving data in databases. View 1) What is a View? A view is a saved SQL query. A view can also be considered as a virtual table. actually retrieves the data from the underlying base tables. vtblEmployee, vtblDepartment Create View vWName as sql query Views can be used to reduce the complexity of the database schema, for non IT users. Views can be used as a mechanism to implement row and column level security. Row Level Security where tblDepartment.DeptName = 'IT' To look at view definition - sp_helptext vWName ; To modify a view - ALTER VIEW statement ; To Drop a view - DROP VIEW vWName. 2) Updateable Views Is it possible to Insert, Update and delete rows, from the underlying tblEmployees table, using view vWEmployeesDataExceptSalary? Yes, SQL server views are updateable. Update vWEmployeesDataExceptSalary Set Name = 'Mikey' Where Id = 2 3) Indexed views when you create an index, on a view, the view gets materialized. This means, the view is now, capable of storing data. In SQL server, we call them Indexed views and in Oracle, Materialized views. vtblProduct , vtblProductSales If you want to create an Index, on a view, the following rules should be followed by the view. For the complete list of all rules, please check MSDN. 1. The view should be created with SchemaBinding option 2. If an Aggregate function in the SELECT LIST, references an expression, and if there is a possibility for that expression to become NULL, then, a replacement value should be specified. In this example, we are using, ISNULL() function, to replace NULL values with ZERO. 3. If GROUP BY is specified, the view select list must contain a COUNT_BIG(*) expression 4. The base tables in the view, should be referenced with 2 part name. In this example, tblProduct and tblProductSales are referenced using dbo.tblProduct and dbo.tblProductSales respectively. Limitation : 1. You cannot pass parameters to a view. Table Valued functions are an excellent replacement for parameterized views. 2.Rules and Defaults cannot be associated with views. 3.The ORDER BY clause is invalid in views unless TOP or FOR XML is also specified. 4.Views cannot be based on temporary tables.

Part 1   How to find nth highest salary in sql
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/2014/05/part-1-how-to-find-nth-highest-salary_17.html This is a very common SQL Server Interview Question. 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

Create a chart using SharePoint list data
This video tutorial shows how to create a chart in SharePoint from list data. http://www.collabion.com/ Collabion Charts for SharePoint provides a quick and easy way to create insightful dashboards in SharePoint®, without the need for MOSS or Excel Services. It works with WSS 3.0, MOSS 2007 and all editions of SharePoint® Server 2010, including Foundation server. Collabion Charts for SharePoint can be installed and used to create your first dashboard in less than 15 minutes. It has a wizard-based installation and chart creation process, which means you never need to write a line of code. The charts are animated, interactive and are sure to "wow" your users. Even if you are already using the default Charts Web Part in SharePoint®, Collabion Charts for SharePoint offers you more chart types, stunning animations, high level of interactivity and support for drill-downs. Collabion Charts for SharePoint lets you create charts from data stored in SharePoint Lists, Views, CSV string or files, MS SQL, Oracle, Excel and BDC. In addition, you can visually specify the data filters using logical and date filters, group them into different data series and define drill-downs to any level. For example, if you wish to plot a sales chart for last 3 years using data stored in SharePoint lists or database, and enable drill-down on this chart, you can use a combination of date-filter (show data for last 3 years), grouping (group data by years) and then enable drill-down to show data first by year, then quarter, month and finally individual days.

SQL Tutorial 11:  Create Views
View is another object that you could store in database. As pre-cursor in preparing reports, view is an effective simplified table from SELECT JOINed query. You don’t need to re-execute a SELECT JOIN that you have defined in the past. Once you have set the correct join, save it on a view. This video tutorial shows on how to create views from given SELECT LEFT JOINs. You may see the structure of a view as if you are describing a table. You can distinguish view from other objects inside a database as you list it with tables. It also shows the work around on how to sort in a specified ORDER BY clause and save it on a view. Normally, view does not accept script with an order by. It includes on how to join table with itself by simply setting up a different alias name.

Part 2   SQL query to get organization hierarchy
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/2014/05/part-2-sql-query-to-get-organization.html To get the best out of this video, the following concepts need to be understood first. These are already discussed in SQL Server Tutorial. 1. Self-Join - http://www.youtube.com/watch?v=qnYSN_7qwgg 2. CTE - http://www.youtube.com/watch?v=ZXB5b-7HJHk 3. Recursive CTE - http://www.youtube.com/watch?v=GGoV0wTMCg0 Here is the problem definition: 1. Employees table contains the following columns a) EmployeeId, b) EmployeeName c) ManagerId 2. If an EmployeeId is passed, the query should list down the entire organization hierarchy i.e who is the manager of the EmployeeId passed and who is managers manager and so on till full hierarchy is listed. For example, Scenario 1: If we pass David's EmployeeId to the query, then it should display the organization hierarchy starting from David. Scenario 2: If we pass Lara's EmployeeId to the query, then it should display the organization hierarchy starting from Lara. We will be Employees table for this demo. SQL to create and populate Employees table with test data Create table Employees ( EmployeeID int primary key identity, EmployeeName nvarchar(50), ManagerID int foreign key references Employees(EmployeeID) ) GO Insert into Employees values ('John', NULL) Insert into Employees values ('Mark', NULL) Insert into Employees values ('Steve', NULL) Insert into Employees values ('Tom', NULL) Insert into Employees values ('Lara', NULL) Insert into Employees values ('Simon', NULL) Insert into Employees values ('David', NULL) Insert into Employees values ('Ben', NULL) Insert into Employees values ('Stacy', NULL) Insert into Employees values ('Sam', NULL) GO Update Employees Set ManagerID = 8 Where EmployeeName IN ('Mark', 'Steve', 'Lara') Update Employees Set ManagerID = 2 Where EmployeeName IN ('Stacy', 'Simon') Update Employees Set ManagerID = 3 Where EmployeeName IN ('Tom') Update Employees Set ManagerID = 5 Where EmployeeName IN ('John', 'Sam') Update Employees Set ManagerID = 4 Where EmployeeName IN ('David') GO Here is the SQL that does the job Declare @ID int ; Set @ID = 7; WITH EmployeeCTE AS ( Select EmployeeId, EmployeeName, ManagerID From Employees Where EmployeeId = @ID UNION ALL Select Employees.EmployeeId , Employees.EmployeeName, Employees.ManagerID From Employees JOIN EmployeeCTE ON Employees.EmployeeId = EmployeeCTE.ManagerID ) Select E1.EmployeeName, ISNULL(E2.EmployeeName, 'No Boss') as ManagerName From EmployeeCTE E1 LEFT Join EmployeeCTE E2 ON E1.ManagerID = E2.EmployeeId

R tutorial: connecting to a database
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

The view then renders the data. Model can be entities or business objects. In part 7, we have built Employee entity. public class Employee { public int EmployeeId { get; set; } public string Name { get; set; } public string Gender { get; set; } public string City { get; set; } } In this video, we will discuss, retrieving data from a database table tblEmployee using entity framework. In a later video, we will discuss using business objects as our model. Step 1: Install entity framework, if you don't have it installed already on your computer. At the time of this recording the latest version is Using nuget package manager, is the easiest way to install. A reference to EntityFramework.dll is automatically added. Open visual studio - Tools - Library Package Manager - Manage NuGet Packages for Solution Step 2: Add EmployeeContext.cs class file to the Models folder. Add the following "using" declaration. using System.Data.Entity; Copy & paste the following code in EmployeeContext.cs public class EmployeeContext : DbContext { // Replace square brackets, with angular brackets public DbSet[Employee] Employees {get; set;} } EmployeeContext class derives from DbContext class, and is responsible for establishing a connection to the database. So the next step, is to include connection string in web.config file. Step 3: Add a connection string, to the web.config file, in the root directory. Step 4: Map "Employee" model class to the database table, tblEmployee using "Table" attribute as shown below. [Table("tblEmployee")] public class Employee { public int EmployeeId { get; set; } public string Name { get; set; } public string Gender { get; set; } public string City { get; set; } } Note: "Table" attribute is present in "System.ComponentModel.DataAnnotations.Schema" namespace. Step 5: Make the changes to "Details()" action method in "EmployeeController" as shown below. public ActionResult Details(int id) { EmployeeContext employeeContext = new EmployeeContext(); Employee employee = employeeContext.Employees.Single(x =] x.EmployeeId == id); return View(employee); } Step 6: Finally, copy and paste the following code in Application_Start() function, in Global.asax file. Database class is present "in System.Data.Entity" namespace. Existing databases do not need, database initializer so it can be turned off. Database.SetInitializer[MVCDemo.Models.EmployeeContext](null); That's it, run the application and notice that the relevant employee details are displayed as expected.
