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

Sequence object Introduced in SQL Server 2012 Generates sequence of numeric values in an ascending or descending order Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/sequence-object-in-sql-server-2012.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/sequence-object-in-sql-server-2012_26.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists Creating the Incrementing Sequence : The following code create a Sequence object that starts with 1 and increments by 1 CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 1 INCREMENT BY 1 Generating the Next Sequence Value : Now we have a sequence object created. To generate the sequence value use NEXT VALUE FOR clause SELECT NEXT VALUE FOR [dbo].[SequenceObject] Output : 1 Every time you execute the above query the sequence value will be incremented by 1. I executed the above query 5 times, so the current sequence value is 5. Retrieving the current sequence value : If you want to see what the current Sequence value before generating the next, use sys.sequences SELECT * FROM sys.sequences WHERE name = 'SequenceObject' Alter the Sequence object to reset the sequence value : ALTER SEQUENCE [SequenceObject] RESTART WITH 1 Select the next sequence value to make sure the value starts from 1 SELECT NEXT VALUE FOR [dbo].[SequenceObject] Using sequence value in an INSERT query : CREATE TABLE Employees ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) -- Generate and insert Sequence values INSERT INTO Employees VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Ben', 'Male') INSERT INTO Employees VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Sara', 'Female') -- Select the data from the table SELECT * FROM Employees Creating the decrementing Sequence : The following code create a Sequence object that starts with 100 and decrements by 1 CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 100 INCREMENT BY -1 Specifying MIN and MAX values for the sequence : Use the MINVALUE and MAXVALUE arguments to specify the MIN and MAX values respectively. Step 1 : Create the Sequence object CREATE SEQUENCE [dbo].[SequenceObject] START WITH 100 INCREMENT BY 10 MINVALUE 100 MAXVALUE 150 Step 2 : Retrieve the next sequence value. The sequence value starts at 100. Every time we call NEXT VALUE, the value will be incremented by 10. SELECT NEXT VALUE FOR [dbo].[SequenceObject] If you call NEXT VALUE, when the value reaches 150 (MAXVALUE), you will get the following error The sequence object 'SequenceObject' has reached its minimum or maximum value. Restart the sequence object to allow new values to be generated. Recycling Sequence values : When the sequence object has reached it's maximum value, and if you want to restart from the minimum value, set CYCLE option ALTER SEQUENCE [dbo].[SequenceObject] INCREMENT BY 10 MINVALUE 100 MAXVALUE 150 CYCLE At this point, whe the sequence object has reached it's maximum value, and if you ask for the NEXT VALUE, sequence object starts from the minimum value again which in this case is 100. To improve performance, the Sequence object values can be cached using the CACHE option. When the values are cached they are read from the memory instead of from the disk, which improves the performance. When the cache option is specified you can also specify the size of th cache , that is the number of values to cache. The following example, creates the sequence object with 10 values cached. When the 11th value is requested, the next 10 values will be cached again. CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 CACHE 10 Using SQL Server Graphical User Interface (GUI) to create the sequence object : 1. Expand the database folder 2. Expand Programmability folder 3. Right click on Sequences folder 4. Select New Sequence Next video : Difference between SEQUENCE and IDENTITY in SQL Server

SQL Tutorial - Sequence Objects
 
22:06
This video will teach you how to create sequence objects with working examples, within SQL Server, we also look at the benefits of sequence objects and some of the differences between a sequence object and identity. CREATE SEQUENCE 'name' AS 'data type' START WITH 'value' INCREMENT BY 'value' MINVALUE 'value' (optional – will default to data type range) MAXVALUE 'value' (optional – will default to data type range) CYCLE? (optional – will default to NO CYCLE) How to find details of sequence objects within the database: sys.sequences – will show all information regarding sequence objects including current value How to restart the value of a sequence object: ALTER SEQUENCE 'name' RESTART WITH 'value' How to drop a sequence: DROP SEQUENCE 'name' (cannot drop a sequence if it is in use!) How to generate the next value for a sequence: SELECT NEXT VALUE FOR 'name' Sequences are covered in the Microsoft Exam – Querying SQL Server (70-461) 2012 / 2014. SQL Statements used below: CREATE SEQUENCE seq_test AS TINYINT START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 100 CYCLE CREATE TABLE Food_Orders ( Id TINYINT DEFAULT NEXT VALUE FOR seq_test , [Date] DATETIME2 , Summary VARCHAR(100) ) CREATE TABLE Food_Orders_2 ( Id TINYINT DEFAULT NEXT VALUE FOR seq_test , [Date] DATETIME2 , Summary VARCHAR(100) ) -- loop to insert data to test sequence DECLARE @N TINYINT = 1 WHILE @N 'less than' 110 BEGIN INSERT INTO Food_Orders([Date], Summary) VALUES (CURRENT_TIMESTAMP, 'Burger and Chips') INSERT INTO Food_Orders_2([Date], Summary) VALUES (CURRENT_TIMESTAMP, 'Burger and Chips') SET @N = @N + 1 END SELECT NEXT VALUE FOR seq_test ALTER SEQUENCE seq_test RESTART WITH 1 DROP SEQUENCE seq_test CREATE SEQUENCE seq_new AS INT START WITH 1 INCREMENT BY -1 SELECT NEXT VALUE FOR seq_new SQL errors covered: The sequence object 'name' has reached its minimum or maximum value. Restart the sequence object to allow new values to be generated Cannot DROP SEQUENCE 'name' because it is being referenced by object 'name'

Difference between sequence and identity in SQL Server
 
05:29
sql server identity vs sequence In this video we will discuss the difference between SEQUENCE and IDENTITY in SQL Server This is continuation to Part 134. Please watch Part 134 from SQL Server tutorial before proceeding. Sequence object is similar to the Identity property, in the sense that it generates sequence of numeric values in an ascending order just like the identity property. However there are several differences between the 2 which we will discuss in this video. Identity property is a table column property meaning it is tied to the table, where as the sequence is a user-defined database object and is not tied to any specific table meaning it's value can be shared by multiple tables. Example : Identity property tied to the Id column of the Employees table. CREATE TABLE Employees ( Id INT PRIMARY KEY IDENTITY(1,1), Name NVARCHAR(50), Gender NVARCHAR(10) ) Example : Sequence object not tied to any specific table CREATE SEQUENCE [dbo].[SequenceObject] AS INT START WITH 1 INCREMENT BY 1 This means the above sequence object can be used with any table. Example : Sharing sequence object value with multiple tables. Step 1 : Create Customers and Users tables CREATE TABLE Customers ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) GO CREATE TABLE Users ( Id INT PRIMARY KEY, Name NVARCHAR(50), Gender NVARCHAR(10) ) GO Step 2 : Insert 2 rows into Customers table and 3 rows into Users table. Notice the same sequence object is generating the ID values for both the tables. INSERT INTO Customers VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Ben', 'Male') INSERT INTO Customers VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Sara', 'Female') INSERT INTO Users VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Tom', 'Male') INSERT INTO Users VALUES (NEXT VALUE for [dbo].[SequenceObject], 'Pam', 'Female') INSERT INTO Users VALUES (NEXT VALUE for [dbo].[SequenceObject], 'David', 'Male') GO Step 3 : Query the tables SELECT * FROM Customers SELECT * FROM Users GO Output : Notice the same sequence object has generated the values for ID columns in both the tables To generate the next identity value, a row has to be inserted into the table, where as with sequence object there is no need to insert a row into the table to generate the next sequence value. You can use NEXT VALUE FOR clause to generate the next sequence value. Example : Generating Identity value by inserting a row into the table INSERT INTO Employees VALUES ('Todd', 'Male') Example : Generating the next sequence value using NEXT VALUE FOR clause. SELECT NEXT VALUE FOR [dbo].[SequenceObject] Maximum value for the identity property cannot be specified. The maximum value will be the maximum value of the correspoding column data type. With the sequence object you can use the MAXVALUE option to specify the maximum value. If the MAXVALUE option is not specified for the sequence object, then the maximum value will be the maximum value of it's data type. Example : Specifying maximum value for the sequence object using the MAXVALUE option CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 MAXVALUE 5 CYCLE option of the Sequence object can be used to specify whether the sequence should restart automatically when the max value (for incrementing sequence object) or min value (for decrementing sequence object) is reached, where as with the Identity property we don't have any such option to automatically restart the identity values. Example : Specifying the CYCLE option of the Sequence object, so the sequence will restart automatically when the max value is exceeded CREATE SEQUENCE [dbo].[SequenceObject] START WITH 1 INCREMENT BY 1 MINVALUE 1 MAXVALUE 5 CYCLE Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-sequence-and.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-sequence-and_27.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Kerberos (protocol)
 
15:22
Kerberos /ˈkɛərbərəs/ is a computer network authentication protocol which works on the basis of 'tickets' to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Its designers aimed it primarily at a client–server model and it provides mutual authentication—both the user and the server verify each other's identity. Kerberos protocol messages are protected against eavesdropping and replay attacks. Kerberos builds on symmetric key cryptography and requires a trusted third party, and optionally may use public-key cryptography during certain phases of authentication. Kerberos uses UDP port 88 by default. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video

Difference between rows and range
 
05:52
range vs rows in sql server difference between rows clause and range clause in sql server range clause vs rows clause in sql server sql server running total query running total example in sql server In this video we will discuss the difference between rows and range in SQL Server. This is continuation to Part 116. Please watch Part 116 from SQL Server tutorial before proceeding. Let us understand the difference with an example. We will use the following Employees table in this demo. SQL Script to create the Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Salary int ) Go Insert Into Employees Values (1, 'Mark', 1000) Insert Into Employees Values (2, 'John', 2000) Insert Into Employees Values (3, 'Pam', 3000) Insert Into Employees Values (4, 'Sara', 4000) Insert Into Employees Values (5, 'Todd', 5000) Go Calculate the running total of Salary and display it against every employee row The following query calculates the running total. We have not specified an explicit value for ROWS or RANGE clause. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary) AS RunningTotal FROM Employees So the above query is using the default value which is RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW This means the above query can be re-written using an explicit value for ROWS or RANGE clause as shown below. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees We can also achieve the same result, by replacing RANGE with ROWS SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees What is the difference between ROWS and RANGE To understand the difference we need some duplicate values for the Salary column in the Employees table. Execute the following UPDATE script to introduce duplicate values in the Salary column Update Employees set Salary = 1000 where Id = 2 Update Employees set Salary = 3000 where Id = 4 Go Now execute the following query. Notice that we get the running total as expected. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees The following query uses RANGE instead of ROWS SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees Notice we don't get the running total as expected. So, the main difference between ROWS and RANGE is in the way duplicate rows are treated. ROWS treat duplicates as distinct values, where as RANGE treats them as a single entity. All together side by side. The following query shows how running total changes 1. When no value is specified for ROWS or RANGE clause 2. When RANGE clause is used explicitly with it's default value 3. When ROWS clause is used instead of RANGE clause SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary) AS [Default], SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS [Range], SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS [Rows] FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-rows-and-range.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-rows-and-range_8.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Simple job using remove duplicate stage in DataStage
 
06:18
The Remove Duplicates stage is a processing stage. It can have a single input link and a single output link. The Remove Duplicates stage takes a single sorted data set as input, removes all duplicate rows, and writes the results to an output data set. Removing duplicate records is a common way of cleansing a data set before you perform further processing. Two rows are considered duplicates if they are adjacent in the input data set and have identical values for the key column(s). A key column is any column you designate to be used in determining whether two rows are identical. The data set input to the Remove Duplicates stage must be sorted so that all records with identical key values are adjacent. You can either achieve this using the in-stage sort facilities available on the Input page Partitioning tab, or have an explicit Sort stage feeding the Remove Duplicates stage.
