IN v/s EXISTS v/s JOIN, which one will give better performance under what condition?
 
04:56
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.

This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'

Creating a database, table, and inserting - SQLite3 with Python 3 part 1
 
10:59
Welcome to an SQLite mini-series! SQLite, as the name suggests, is a lite version of an SQL database. SQLite3 comes as a part of the Python 3 standard library. Databases offer, typically, a superior method of high-volume data input and output over a typical file such as a text file. SQLite is a "light" version that works based on SQL syntax. SQL is a programming language in itself, but is a very popular database language. Many websites use MySQL, for example. SQLite truly shines because it is extremely lightweight. Setting up an SQLite database is nearly instant, there is no server to set up, no users to define, and no permissions to concern yourself with. For this reason, it is often used as a developmental and protyping database, but it can and is used in production. The main issue with SQLite is that it winds up being much like any other flat-file, so high volume input/output, especially with simultaneous queries, can be problematic and slow. You may then ask, what really is the difference between a typical file and sqlite. First, SQLite will let you structure your data as a database, which can easily be queried, so you get that functionality both with adding new content and calling upon it later. Each table would likely need its own file if you were doing plain files, and SQLite is all in one. SQLite is also going to be buffering your data. A flat file will require a full load before you can start querying the full dataset, SQLite files don't work that way. Finally, edits do not require the entire file to be re-saved, it's just that part of the file. This improves performance significantly. Alright great, let's dive into some SQLite. https://pythonprogramming.net/sql-database-python-part-1-inserting-database/ Playlist: https://www.youtube.com/playlist?list=PLQVvvaa0QuDezJh0sC5CqXLKZTSKU1YNo https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

Part 11   Real time example for right join
 
07:17
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-11-real-time-example-for-right-join.html In my opinion this is a very good sql server interview question. Here are the sequence of questions, one of our Youtube channel subscribers faced in a sql server interview. Question 1: Can you list different types of JOINS available in SQL Server Answer: Inner Join, Left Join, Right Join, Full Join and Cross Join Question 2: Can you tell me the purpose of Right Join? Answer: Right Join returns all rows from the Right Table irrespective of whether a match exists in the left table or not. Question 3: Can you give me an example? Answer: Consider Departments and Employees tables. In this case we use RIGHT JOIN To retrieve all Department and Employee names, irrespective of whether a Department has Employees or not. Select DepartmentName, EmployeeName From Employees Right Join Departments On Employees.DepartmentID = Departments.DepartmentID Question 4: I accept you have understood the purpose of Right Join. Based on the above 2 tables, can you give me any other business case for using Right Join. At this point the candidate being interviewed, had no other answer and he simply told the interviewer he can't think of anything else. The good news is that, inspite of not answering the last question, the candidate got this Job. The candidate then emailed me and asked, what do you think that interviewer might be looking for here? Here is what I think the interviewer is looking for. I may be wrong. If you can think of anything else, please feel free to leave a comment so it could help someone else. Another business case for using RIGHT JOIN on the above 2 tables is to retrieve all the Department Names and the total number of Employees with in each department. SQL Query with Right Join Select DepartmentName, Count(Employees.DepartmentID) as TotalEmployees From Employees Right Join Departments ON Departments.DepartmentID = Employees.DepartmentID Group By DepartmentName Order By TotalEmployees

JDBC Tutorials - 5 - Java Program to "Select Rows from Table"
 
08:52
From the above video you can understand how to write java code to select rows from table using SQL Select statement. Steps to Write Code. 1. The very first step is to Load the JDBC-MySQL Driver. try { Class.forName("com.mysql.jdbc.Driver"); }catch(Exception e){ } The above java code will load the driver using try-catch statement, because the Class.forName() method will throw class not found Exception. 2. Second Step is to Establish the Connection try{ Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/simpledb", "root", "123"); }catch(Exception e){ } The above java code will establish the connection to the database "simpledb" using its user: root and password: 123 3. Third step is to create an SQL statement and pass to "simpledb" try{ String sql = "select * from emp"; Statement stmt = conn.createStatement(); ResultSet res = stmt.executeQuery(sql); }catch(Exception e){ } The above code snippet will pass SQL statement to the database and obtain rows of "emp" table. The rows obtained will be stored in the ResultSet object. 4. Fourth step is to query the ResultSet object. and to print output. For more tutorials visit: http://www.step2know.com

SQL для начинающих. Пересечение строк в базах данных SQLite. SQL запрос SELECT INTERSECT
 
04:02
Рассмотрим более подробно операцию пересечения строк, которая выполняется при помощи SQL запроса SELECT INTERSECT. Напомню, что операция SELECT INTERSECT симметрична, а этом означает, что не имеет значения какая таблица будет слева от ключевого слова, а какая справа - результат будет одинаковым. Также нам стоит заметить, что при выполнении запроса INTERSECT SQlite будет сравнивать строки из первой промежуточной таблицы со строками второй таблицы, поэтому операция SELECT INTERSECT довольно-таки дорогая. Стоит обратить внимание на то, что в сравниваемых запросах мы можем использовать любые уточняющие фразы: HAVING, WHERE, ORDER BY, LIMIT, GROUP BY и другие.
