Oracle SQL: UNION vs UNION ALL
 
04:45
https://www.databasestar.com/union-vs-union-all/ In this video, we’ll learn what the UNION and UNION ALL keywords are, and see what the differences between them are. The UNION and UNION ALL keywords are both set operators, meaning they work with sets of data. They are used to combine two result sets into one. They are very similar, unlike the INTERSECT and MINUS keywords which reduce the data that is shown in the result set. But other than a slight difference in their name, how can we compare Oracle SQL UNION vs UNION ALL? The main difference is how duplicates are treated, which I explain in this video. I also cover the performance differences of these two keywords, and which one is recommended. For more information on UNION and UNION ALL, including the code from these examples, refer to the related article here: https://www.databasestar.com/union-vs-union-all/

difference between union and union all difference between intersect and union difference between intersect and except in sql server union vs union all sql server union vs intersect sql server intersect vs except In this video we will discuss the difference between union intersect and except in sql server with examples. UNION operator returns all the unique rows from both the left and the right query. UNION ALL included the duplicates as well. INTERSECT operator retrieves the common unique rows from both the left and the right query. EXCEPT operator returns unique rows from the left query that aren’t in the right query’s results. UNION operator returns all the unique rows from both the queries. Notice the duplicates are removed. Select Id, Name, Gender from TableA UNION Select Id, Name, Gender from TableB UNION ALL operator returns all the rows from both the queries, including the duplicates. Select Id, Name, Gender from TableA UNION ALL Select Id, Name, Gender from TableB INTERSECT operator retrieves the common unique rows from both the left and the right query. Notice the duplicates are removed. Select Id, Name, Gender from TableA INTERSECT Select Id, Name, Gender from TableB EXCEPT operator returns unique rows from the left query that aren’t in the right query’s results. Select Id, Name, Gender from TableA EXCEPT Select Id, Name, Gender from TableB If you wnat the rows that are present in Table B but not in Table A, reverse the queries. Select Id, Name, Gender from TableB EXCEPT Select Id, Name, Gender from TableA For all these 3 operators to work the following 2 conditions must be met The number and the order of the columns must be same in both the queries The data types must be same or at least compatible For example, if the number of columns are different, you will get the following error Msg 205, Level 16, State 1, Line 1 All queries combined using a UNION, INTERSECT or EXCEPT operator must have an equal number of expressions in their target lists.

Grouping Sets in SQL Server
 
09:36
grouping sets examples in sql server sql server grouping sets order by grouping sql server 2008 grouping sets example sql server group by union all Grouping sets is a new feature introduced in SQL Server 2008. Let us understand Grouping sets with an example. We want to calculate Sum of Salary by Country and Gender. We can very easily achieve this using a Group By query as shown below Select Country, Gender, Sum(Salary) as TotalSalary From Employees Group By Country, Gender Within the same result set we also want Sum of Salary just by Country. To achieve the above result we could combine 2 Group By queries using UNION ALL as shown below. Select Country, Gender, Sum(Salary) as TotalSalary From Employees Group By Country, Gender UNION ALL Select Country, NULL, Sum(Salary) as TotalSalary From Employees Group By Country Within the same result set we also want Sum of Salary just by Gender. We can achieve this by combining 3 Group By queries using UNION ALL as shown below Select Country, Gender, Sum(Salary) as TotalSalary From Employees Group By Country, Gender UNION ALL Select Country, NULL, Sum(Salary) as TotalSalary From Employees Group By Country UNION ALL Select NULL, Gender, Sum(Salary) as TotalSalary From Employees Group By Gender Finally we also want the grand total of Salary. In this case we are not grouping on any particular column. So both Country and Gender columns will be NULL in the resultset. To achieve this we will have to combine the fourth query using UNION ALL as shown below. Select Country, Gender, Sum(Salary) as TotalSalary From Employees Group By Country, Gender UNION ALL Select Country, NULL, Sum(Salary) as TotalSalary From Employees Group By Country UNION ALL Select NULL, Gender, Sum(Salary) as TotalSalary From Employees Group By Gender UNION ALL Select NULL, NULL, Sum(Salary) as TotalSalary From Employees There are 2 problems with the above approach. The query is huge as we have combined different Group By queries using UNION ALL operator. This can grow even more if we start to add more groups The Employees table has to be accessed 4 times, once for every query. If we use Grouping Sets feature introduced in SQL Server 2008, the amount of T-SQL code that you have to write will be greatly reduced. The following Grouping Sets query produce the same result as the above UNION ALL query. Select Country, Gender, Sum(Salary) TotalSalary From Employees Group BY GROUPING SETS ( (Country, Gender), -- Sum of Salary by Country and Gender (Country), -- Sum of Salary by Country (Gender) , -- Sum of Salary by Gender () -- Grand Total ) The order of the rows in the result set is not the same as in the case of UNION ALL query. To control the order use order by as shown below. Select Country, Gender, Sum(Salary) TotalSalary From Employees Group BY GROUPING SETS ( (Country, Gender), -- Sum of Salary by Country and Gender (Country), -- Sum of Salary by Country (Gender) , -- Sum of Salary by Gender () -- Grand Total ) Order By Grouping(Country), Grouping(Gender), Gender Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/grouping-sets-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/grouping-sets-in-sql-server_19.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

Chapter 9 : SQL Set Operators
 
12:30
Set operators are used to join the results of two (or more) SELECT statements.The SET operators available in Oracle 11g are UNION,UNION ALL,INTERSECT,and MINUS. Same number of columns must be selected by all participating SELECT statements.Column names used in the display are taken from the first query. Data types of the column list must be compatible/implicitly convertible by oracle. Oracle will not perform implicit type conversion if corresponding columns in the component queries belong to different data type groups.For example, if a column in the first component query is of data type DATE, and the corresponding column in the second component query is of data type CHAR,Oracle will not perform implicit conversion, but raise ORA-01790 error. Positional ordering must be used to sort the result set. Individual result set ordering is not allowed with Set operators. ORDER BY can appear once at the end of the query. For example, UNION and INTERSECT operators are commutative, i.e. the order of queries is not important; it doesn't change the final result. Performance wise, UNION ALL shows better performance as compared to UNION because resources are not wasted in filtering duplicates and sorting the result set. Set operators can be the part of sub queries. Set operators can't be used in SELECT statements containing TABLE collection expressions. The LONG, BLOB, CLOB, BFILE, VARRAY,or nested table are not permitted for use in Set operators.For update clause is not allowed with the set operators.

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

sql server group by rollup sql server 2008 group by rollup group by with rollup example sql rollup example sql server rollup example sql server 2008 rollup examples rollup clause in sql server rollup function in sql server ROLLUP in SQL Server is used to do aggregate operation on multiple levels in hierarchy. Let us understand Rollup in SQL Server with examples. We will use the following Employees table for the examples in this video. Retrieve Salary by country along with grand total There are several ways to achieve this. The easiest way is by using Rollup with GroupBy. SELECT Country, SUM(Salary) AS TotalSalary FROM Employees GROUP BY ROLLUP(Country) The above query can also be rewritten as shown below SELECT Country, SUM(Salary) AS TotalSalary FROM Employees GROUP BY Country WITH ROLLUP We can also use UNION ALL operator along with GROUP BY SELECT Country, SUM(Salary) AS TotalSalary FROM Employees GROUP BY Country UNION ALL SELECT NULL, SUM(Salary) AS TotalSalary FROM Employees We can also use Grouping Sets to achieve the same result SELECT Country, SUM(Salary) AS TotalSalary FROM Employees GROUP BY GROUPING SETS ( (Country), () ) Let's look at another example. Group Salary by Country and Gender. Also compute the Subtotal for Country level and Grand Total as shown below. Using ROLLUP with GROUP BY SELECT Country, Gender, SUM(Salary) AS TotalSalary FROM Employees GROUP BY ROLLUP(Country, Gender) OR SELECT Country, Gender, SUM(Salary) AS TotalSalary FROM Employees GROUP BY Country, Gender WITH ROLLUP Using UNION ALL with GROUP BY SELECT Country, Gender, SUM(Salary) AS TotalSalary FROM Employees GROUP BY Country, Gender UNION ALL SELECT Country, NULL, SUM(Salary) AS TotalSalary FROM Employees GROUP BY Country UNION ALL SELECT NULL, NULL, SUM(Salary) AS TotalSalary FROM Employees Using GROUPING SETS SELECT Country, Gender, SUM(Salary) AS TotalSalary FROM Employees GROUP BY GROUPING SETS ( (Country, Gender), (Country), () ) Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/rollup-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/rollup-in-sql-server_20.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
