12 of 15 SQL Basics with Oracle - Aggregate (grouping) functions and the GROUP BY clause
 
09:33
This video explains the GROUP BY clause and some of the aggregate functions: sum, count, average, maximum, minimum, count(distinct ...), etc. An example of using an aggregate function would be to group students by major and only show the number of students in each major, not individual student information. (12 of 15) There is also an "Advanced SQL" series. (Search for "databasemec" for tutorials using SQL Server.)

Grouping function in SQL Server
 
12:49
sql server rollup grouping sql server rollup replace null sql server rollup grouping replace null In this video we will discuss the use of Grouping function in SQL Server. This is continuation to Part 104. Please watch Part 104 from SQL Server tutorial before proceeding. What is Grouping function Grouping(Column) indicates whether the column in a GROUP BY list is aggregated or not. Grouping returns 1 for aggregated or 0 for not aggregated in the result set. The following query returns 1 for aggregated or 0 for not aggregated in the result set SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING(Continent) AS GP_Continent, GROUPING(Country) AS GP_Country, GROUPING(City) AS GP_City FROM Sales GROUP BY ROLLUP(Continent, Country, City) What is the use of Grouping function in real world When a column is aggregated in the result set, the column will have a NULL value. If you want to replace NULL with All then this GROUPING function is very handy. SELECT CASE WHEN GROUPING(Continent) = 1 THEN 'All' ELSE ISNULL(Continent, 'Unknown') END AS Continent, CASE WHEN GROUPING(Country) = 1 THEN 'All' ELSE ISNULL(Country, 'Unknown') END AS Country, CASE WHEN GROUPING(City) = 1 THEN 'All' ELSE ISNULL(City, 'Unknown') END AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Can't I use ISNULL function instead as shown below SELECT ISNULL(Continent, 'All') AS Continent, ISNULL(Country, 'All') AS Country, ISNULL(City, 'All') AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Well, you can, but only if your data does not contain NULL values. Let me explain what I mean. At the moment the raw data in our Sales has no NULL values. Let's introduce a NULL value in the City column of the row where Id = 1 Update Sales Set City = NULL where Id = 1 Now execute the following query with ISNULL function SELECT ISNULL(Continent, 'All') AS Continent, ISNULL(Country, 'All') AS Country, ISNULL(City, 'All') AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Notice that the actuall NULL value in the raw data is also replaced with the word 'All', which is incorrect. Hence the need for Grouping function. Please note : Grouping function can be used with Rollup, Cube and Grouping Sets Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/grouping-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/grouping-function-in-sql-server_25.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

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

How to Code Oracle Analytic Functions
 
52:40
Many more free Oracle Database and SQL tutorials at http://skillbuilders.com/free-oracle-tutorials. SQL is a language that allows you to perform queries to answer a wide range of questions about your data. While standard SQL is quite powerful, there are many questions that it cannot answer at all or that it can only answer with complex and inefficient SQL workarounds. Questions about running totals, percent of total, and ranking within a group fall into this area. Also, more complex issues such as Top-N within a group and aggregates over a range also fall in this arena. These questions can be easily answered via a new class of SQL statements called Analytic Functions. This presentation will show you how to use Oracle's Analytic Function extensions to SQL to answer these questions simply and efficiently.

In this video we begin to explore Window Functions and their purpose within SQL Server. Window Functions are used for performing data analysis calculations and address an important need compared to the GROUP BY clause that we are able to return the underlying data in the same query. This video shows an example of the differences between the GROUP BY clause and Window Functions. Window Functions were first introduced in SQL Server 2005 but further enhancements and support was added in SQL Server 2012. We look at the OVER clause and PARTITION BY. Window Functions can only be included within SELECT or ORDER BY clauses. Functions Available: Aggregate - COUNT, SUM, MIN, MAX, AVG Offset - FIRST_VALUE, LAST_VALUE, LEAD, LAG Statistical - PERCENT_RANK, CUME_DIST, PERCENTILE_CONT, PERCENTILE_DIST Windows Functions also have FRAMES ROWS RANGE Window Functions are a powerful tool within SQL Server and I am excited to bring more videos and tutorials working with Window Functions in the future. Code: WITH CTE AS ( SELECT Sales_Id , SUM(Line_Total) AS Total FROM Sales_Details GROUP BY Sales_Id ) SELECT * FROM CTE AS A INNER JOIN Sales_Details AS B ON A.Sales_Id = B.Sales_Id SELECT Sales_Id , Sales_Date , Item , Price , Quantity , Line_Total , COUNT(Line_Total) OVER(PARTITION BY Sales_Id) AS Line_Count , SUM(Line_Total) OVER(PARTITION BY Sales_Id) AS Sales_Total , SUM(Line_Total) OVER(PARTITION BY Sales_Date) AS Daily_Total , SUM(Line_Total) OVER() AS Total FROM Sales_Details ORDER BY Sales_Total

GROUPING ID function in SQL Server
 
12:38
grouping_id function in sql server 2008 grouping_id in sql server 2008 example sql server grouping level In this video we will discuss 1. GROUPING_ID function in SQL Server 2. Difference between GROUPING and GROUPING_ID functions 3. Use of GROUPING_ID function GROUPING_ID function computes the level of grouping. Difference between GROUPING and GROUPING_ID Syntax : GROUPING function is used on single column, where as the column list for GROUPING_ID function must match with GROUP BY column list. GROUPING(Col1) GROUPING_ID(Col1, Col2, Col3,...) GROUPING indicates whether the column in a GROUP BY list is aggregated or not. Grouping returns 1 for aggregated or 0 for not aggregated in the result set. GROUPING_ID() function concatenates all the GOUPING() functions, perform the binary to decimal conversion, and returns the equivalent integer. In short GROUPING_ID (A, B, C) = GROUPING(A) + GROUPING(B) + GROUPING(C) Let us understand this with an example. SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, CAST(GROUPING(Continent) AS NVARCHAR(1)) + CAST(GROUPING(Country) AS NVARCHAR(1)) + CAST(GROUPING(City) AS NVARCHAR(1)) AS Groupings, GROUPING_ID(Continent, Country, City) AS GPID FROM Sales GROUP BY ROLLUP(Continent, Country, City) Row Number 1 : Since the data is not aggregated by any column GROUPING(Continent), GROUPING(Country) and GROUPING(City) return 0 and as result we get a binar string with all ZEROS (000). When this converted to decimal we get 0 which is displayed in GPID column. Row Number 7 : The data is aggregated for Country and City columns, so GROUPING(Country) and GROUPING(City) return 1 where as GROUPING(Continent) return 0. As result we get a binar string (011). When this converted to decimal we get 10 which is displayed in GPID column. Row Number 15 : This is the Grand total row. Notice in this row the data is aggregated by all the 3 columns. Hence all the 3 GROUPING functions return 1. So we get a binary string with all ONES (111). When this converted to decimal we get 7 which is displayed in GPID column. Use of GROUPING_ID function : GROUPING_ID function is very handy if you want to sort and filter by level of grouping. Sorting by level of grouping : SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING_ID(Continent, Country, City) AS GPID FROM Sales GROUP BY ROLLUP(Continent, Country, City) ORDER BY GPID Filter by level of grouping : The following query retrieves only continent level aggregated data SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING_ID(Continent, Country, City) AS GPID FROM Sales GROUP BY ROLLUP(Continent, Country, City) HAVING GROUPING_ID(Continent, Country, City) = 3 Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/groupingid-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/groupingid-function-in-sql-server_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

Oracle NVL Function Explained with Examples
 
09:25
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL function allows you to check a value and return a different value if that value is NULL. It’s great for using another value if the first one is NULL or an optional value, for example people’s phone numbers. It’s also good alongside aggregate functions and grouping so you can see what the difference is between a subtotal row and an actual NULL value. The syntax of the Oracle NVL function is: NVL( check_value, replace_value ) The parameters are: - check_value (mandatory): This is the value that is displayed to the user. It is also the value that is checked for NULL. - replace_value (mandatory): This is the value that appears if the check_value is NULL. The function can use many different data types as parameters: string, date, or numeric. However, both parameters need to be the same type. For more information about the Oracle NVL function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/

If the WHERE condition is not specified, then the query returns the total number of rows in the table. For Example: If you want the number of emps in a particular department, the query would be: SELECT COUNT (*) FROM emp WHERE deptno = 10; If you want the total number of emps in all the department, the query would take the form: SELECT COUNT (*) FROM emp; SQL DISTINCT(): This function is used to select the distinct rows. For Example: If you want to select all distinct department names from emp table, the query would be: SELECT DISTINCT deptno FROM emp; To get the count of emps with unique name, the query would be: SELECT COUNT (DISTINCT name) FROM emp; SQL MAX(): This function is used to get the maximum value from a column. To get the maximum salary drawn by an emp, the query would be: SELECT MAX (salary) FROM emp; SQL MIN(): This function is used to get the minimum value from a column. To get the minimum salary drawn by an emp, he query would be: SELECT MIN (salary) FROM emp; SQL AVG(): This function is used to get the average value of a numeric column. To get the average salary, the query would be SELECT AVG (salary) FROM emp; SQL SUM(): This function is used to get the sum of a numeric column To get the total salary given out to the emps, SELECT SUM (salary) FROM emp;
