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.

Oracle ADD_MONTHS Function
 
03:15
https://www.databasestar.com/oracle-add_months/ The Oracle ADD_MONTHS allows you to add a specified number of months to a date value, and return the new date value. It’s great for performing calculations on dates, or date arithmetic, which can be hard in many different programming languages. The syntax of the ADD_MONTHS function is: ADD_MONTHS ( input_date, number_months ) The function returns a DATE value. The parameters of this function are: - input_date (mandatory): This is the starting date, or the date that you will add a number of months to. - number_months (mandatory): This is an integer value that represents the number of months to add to input_date. The input_date can be any datetime value, or even a character value that can be converted to a date. Also, the number_months can be any number value, or a character value that can be converted to a number. What if the number of days in the two months are different? For example, adding a month to Jan 31 could result in Feb 31, which does not exist. Well, in this case, Oracle would work out that the date does not exist, and use the last date of the month (e.g. Feb 28). You can also provide a negative value for ADD_MONTHS to subtract months from the specified date. For more information about the Oracle ADD_MONTHS function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-add_months/

09 of 15 SQL Basics with Oracle - Using IN, NOT IN, NULL and NOT NULL
 
05:02
This video shows how to use the IN clause as an alternative to using the OR operators. The IN clause is more compact--it's easier to type and read than multiple OR criteria. Examples of checking for NULL and NOT NUL are also given. (9 of 15) There is also an "Advanced SQL" series. (Search for "databasemec" for tutorials using SQL Server.)

Основы SQL. SQL подзапросы SELECT и связанные подзапросы в базах данных SQLite. SQL оператор EXISTS
 
11:44
Ранее мы рассмотрели оператор IN и тогда мы сказали, что данный оператор может быть использован для написания подзапросов. Также для подзапросов очень часто используется SQL оператор EXISTS. Оператор EXISTS переводится на русский язык как "существует". Когда мы работали с объектами базы данных, то очень часто использовали конструкции: IF EXISTS и IF NOT EXISTS. Когда оператор EXISTS используется вместе с SQL командой SELECT, то выполняется "проверка на существование" и СУБД определяет: выводить результаты нам на экран или нет. Вообще, подзапросы в SQL можно использовать с любыми операторами и даже использовать подзапрос вместо имени таблицы или имени столбца, так как SELECT всегда нам в качестве результата возвращает таблицу.

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?

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

SQL Server except operator
 
05:14
sql except example sql except operator example sql server except example sql server except order by sql server except clause SQL Server except operator In this video we will discuss SQL Server except operator with examples. EXCEPT operator returns unique rows from the left query that aren’t in the right query’s results. Introduced in SQL Server 2005 The number and the order of the columns must be the same in all queries The data types must be same or compatible This is similar to minus operator in oracle Let us understand this with an example. SQL Script to create the tables Create Table TableA ( Id int primary key, Name nvarchar(50), Gender nvarchar(10) ) Go Insert into TableA values (1, 'Mark', 'Male') Insert into TableA values (2, 'Mary', 'Female') Insert into TableA values (3, 'Steve', 'Male') Insert into TableA values (4, 'John', 'Male') Insert into TableA values (5, 'Sara', 'Female') Go Create Table TableB ( Id int primary key, Name nvarchar(50), Gender nvarchar(10) ) Go Insert into TableB values (4, 'John', 'Male') Insert into TableB values (5, 'Sara', 'Female') Insert into TableB values (6, 'Pam', 'Female') Insert into TableB values (7, 'Rebeka', 'Female') Insert into TableB values (8, 'Jordan', 'Male') Go Notice that the following query returns the unique rows from the left query that aren’t in the right query’s results.

Oracle SQL Tutorial 15 - How to Add Primary Key Constraints
 
02:54
The goal of this video is to take the CREATE TABLE statement we have and walk through the different ways to create primary keys. This and foreign keys are the most common constraints, so we need to make sure that you have this one down. Once we have a more complex database design with multiple tables, we will learn the proper way to create foreign keys. For now, I am going to keep all of our constraints at the column level, unnamed. The only exception is the primary key, because that is what we are focusing on in this video. The first way to create the primary key is at the column level, unnamed. The primary key is very important because it what we use to distinguish rows from one another. Every table you create is going to need a primary key, and I suggest putting a lot of effort into making sure your keys are set up correctly and organized. --Delete the table if needed: DROP TABLE users; CREATE TABLE users( user_id NUMBER PRIMARY KEY, username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) The next way is at the column level, but named: --Delete the table: DROP TABLE users; CREATE TABLE users( user_id NUMBER CONSTRAINT users_pk PRIMARY KEY, username VARCHAR2(50 CHAR)NOT NULL UNIQUE ) The general naming convention here is the table name followed by an underscore, followed by pk for primary key. Finally, the third way, which is at the table level, is the way we are going to create our primary key: --Delete the table: DROP TABLE users; CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) NOT NULL UNIQUE, CONSTRAINT users_pk PRIMARY KEY (user_id) ) Now, once you've created these constraints, you can use Oracle SQL Developer to find these constraints. Open your databases in the connections tab and find the table in the Tables folder. Double click your table and travel to the Constraints tab. You can tell here that the UNIQUE constraint still exists in this table, but it has a pretty disgusting name. It kind of wants to make me puke. Referencing that constraint in the future with that wacky name would be a burden. Engrave these three options in your head so that you can use any of them whenever you need and can read other peoples' code. Thank you for sticking with the series thus far. In the next video, we will be…doing something. See you then! :) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Part 12   Can we join two tables without primary foreign key relation
 
10:38
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/2014/09/part-12-can-we-join-two-tables-without.html Can we join two tables without primary foreign key relation Yes, we can join two tables without primary foreign key relation as long as the column values involved in the join can be converted to one type. ID column in Departments table is not the primary Key and DepartmentId column in Employees table is not the foreign key. But we can still join these tables using ID column from Departments table and DepartmentId column from Employees table, as both the columns involved in the join have same data type i.e int. Select Employees.Name as EmployeeName, Departments.Name as DepartmentName from Employees join Departments on Departments.ID = Employees.DepartmentId The obious next question is, if primary foreign key relation is not mandatory for 2 tables to be joined then what is the use of these keys? Primary key enforces uniqueness of values over one or more columns. Since ID is not a primary key in Departments table, 2 or more departments may end up having same ID value, which makes it impossible to distinguish between them based on the ID column value. Foreign key enforces referential integrity. Without foreign key constraint on DepartmentId column in Employees table, it is possible to insert a row into Employees table with a value for DepartmentId column that does not exist in Departments table. The following insert statement, successfully inserts a new Employee into Employees table whose DepartmentId is 100. But we don't have a department with ID = 100 in Departments table. This means this employee row is an orphan row, and the referential integrity is lost as result Insert into Employees values (8, 'Mary', 'Female', 80000, 100) If we have had a foreign key constraint on DepartmentId column in Employees table, the following insert statement would have failed with the following error. Msg 547, Level 16, State 0, Line 1 The INSERT statement conflicted with the FOREIGN KEY constraint. The conflict occurred in database "Sample", table "dbo.Departments", column 'ID'.

SQL SERVER PART-12: Oracle Linked Database Server
 
03:46
HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO. SQL server 2017 makes it easy to configure linked server. You can use open-query to get or manipulate data of linked server database. CONFIGURATION SUMMARY: PROVIDER : oracle provider for oledb. DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name. e.g. 192.168.1.10:5121/orcl OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ') Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages: • The ability to access data from outside of SQL Server. • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise. • The ability to address diverse data sources similarly. An oracle linked server require OLE DB provider. An OLE DB provider is a DLL that manages and interacts with a specific data source. If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers. An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

Part 11   Real time example for right join

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

Oracle SQL Tutorial 16 - Parent Child Relationships
 
06:09
So far in this series we have discussed database design, creating tables, and constraints. We've brought up the concept of foreign keys, but we have not explained how to create them. That is the goal of this video and the upcoming videos. We want to study those foreign keys! Let's make them not so foreign. Let's learn the proper way to define a foreign key. As a reminder, a foreign key is a column that references a column of another table. The column it references must either be a primary key, or have the UNIQUE constraint. This means that every value inside of the column that is labeled as a foreign key, there must be that value in some row of the referenced column. As an example, imagine that we have the users table, and we have a table service_requests. We could have a column in the service_request that references a column in the users table. Usually this would be the primary key that is referenced, but there is nothing stopping you from referencing a unique column. Just for fun, let's go through an example using the username column. If we have a service_requests table, every single row within the table is going to be what some would consider an instance of a service_request. This means that the table columns are like the blueprint for what a service request looks like and then each row is an individual service request. If we have one of the columns labeled as a foreign key to the username of the users table, what does that mean practically? It means that for a single row, the value for that column must be a value that exists in the users table. We could have a service_request submitted by a user with the username of Yoloswagman. This means that there must be a row inside of the users table that has the value Yoloswagman for the username column. This brings up the concept of parent and child relationships. Yoloswagman in this situation is the parent, and his service request is the child. When we draw it out, it makes sense why a primary key must be UNIQUE. If we had two Yoloswagmans, the child would not know which column is the parent. The same applies if we were using IDs and we had So remember, always reference a primary key or a column with the UNIQUE constraint. Now, I have a question for you. Do foreign keys automatically have the UNIQUE constraint, just like primary keys? The answer is no. A parent row can have many child rows. It makes sense because the user could submit multiple service requests. Can we force the column to be unique? Absolutely. If that was the case, the user could only make one service request. Another question. Do foreign keys automatically have the NOT NULL constraint, just like primary keys? The answer is no. Essentially what this means is that a child could be created with no parent. Can we force the column to be NOT NULL? Absolutely. It is ok in some situations to allow the row to be null, but in this situation it makes no sense. It would be wise for us to add that constraint ourselves. So now that you understand some more differences between primary and foreign keys and parent child relationships, take all of these questions into consideration when you are creating foreign keys. In the next video, we are going to start a small project that is going to require multiple tables. We'll take a video to design our structure and then we'll get to creating those foreign keys in Oracle SQL Developer.
