SQL Tutorial : Difference Between Count(1) and Count(*) in SQL Oracle SQL Tutorial SQL Tutorial for beginners PLSQL Tutorial PLSQL Tutorial for beginners PL/SQL Tutorial PL SQL Tutorial PL SQL Tutorial for beginners PL/SQL Tutorial for beginners Oracle SQL Tutorial

https://www.databasestar.com/oracle-count/ The Oracle COUNT function is used to count the number of rows from the column, or number of values, provided to it. It’s commonly used to find the number of rows returned by a SELECT query. The syntax of the COUNT function is: COUNT ( [ * | [ DISTINCT | ALL ] expression) [ over (analytic_clause) ] There’s a lot of square brackets here, indicating optional parameters and choices. This just means you can use the COUNT function in a few different ways: COUNT(*) COUNT(DISTINCT expression) COUNT(ALL expression) COUNT(*) OVER (analytic_clause) COUNT(DISTINCT expression) OVER (analytic_clause) COUNT(ALL expression) OVER (analytic_clause) It can be used as an aggregate or analytic function. The parameters of the COUNT function are: - expression: The expression to count the values of. This can be a column or a set of values, for example. - analytic_clause: This is used to specify the criteria for an analytic query. COUNT(*) is the most common way to use this function, I’ve found. As COUNT(*) is an aggregate function, like all aggregate functions the columns mentioned in the SELECT clause need to exist in the GROUP BY clause. NULL values are ignored by COUNT(expression), but they are counted when using COUNT(*). COUNT(*) has the exact same calculation and performance as COUNT(1). For more information about the Oracle COUNT function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-count/

In this video I use the COUNT and SUM functions available to the SQL language. I used the COUNT function to add up the number of records in my query. This function works well with all data types and will just count the number or records that result from the conditions of your query. The SUM function will add up the numeric values and produce a total amount of a column. When using a function be sure to use parenthesis around the column you are performing the function on. This video is part of a series of videos with the purpose of learning the SQL language. For more information visit Lecture Snippets at http://lecturesnippets.com.

Dates in Oracle PL SQL is definitely the most powerful among all other databases. It gives us full flexibility to manipulate it of our choice, whether you are calculating days, months or year, printing date and time in various format. Useful date functions add_months, months_between, last_day, next_day and to_char helps us a lot in handling date time in our pl sql programming.

Recursive CTE - http://www.youtube.com/watch?v=GGoV0wTMCg0 Here is the problem definition: 1. Employees table contains the following columns a) EmployeeId, b) EmployeeName c) ManagerId 2. If an EmployeeId is passed, the query should list down the entire organization hierarchy i.e who is the manager of the EmployeeId passed and who is managers manager and so on till full hierarchy is listed. For example, Scenario 1: If we pass David's EmployeeId to the query, then it should display the organization hierarchy starting from David. Scenario 2: If we pass Lara's EmployeeId to the query, then it should display the organization hierarchy starting from Lara. We will be Employees table for this demo. SQL to create and populate Employees table with test data Create table Employees ( EmployeeID int primary key identity, EmployeeName nvarchar(50), ManagerID int foreign key references Employees(EmployeeID) ) GO Insert into Employees values ('John', NULL) Insert into Employees values ('Mark', NULL) Insert into Employees values ('Steve', NULL) Insert into Employees values ('Tom', NULL) Insert into Employees values ('Lara', NULL) Insert into Employees values ('Simon', NULL) Insert into Employees values ('David', NULL) Insert into Employees values ('Ben', NULL) Insert into Employees values ('Stacy', NULL) Insert into Employees values ('Sam', NULL) GO Update Employees Set ManagerID = 8 Where EmployeeName IN ('Mark', 'Steve', 'Lara') Update Employees Set ManagerID = 2 Where EmployeeName IN ('Stacy', 'Simon') Update Employees Set ManagerID = 3 Where EmployeeName IN ('Tom') Update Employees Set ManagerID = 5 Where EmployeeName IN ('John', 'Sam') Update Employees Set ManagerID = 4 Where EmployeeName IN ('David') GO Here is the SQL that does the job Declare @ID int ; Set @ID = 7; WITH EmployeeCTE AS ( Select EmployeeId, EmployeeName, ManagerID From Employees Where EmployeeId = @ID UNION ALL Select Employees.EmployeeId , Employees.EmployeeName, Employees.ManagerID From Employees JOIN EmployeeCTE ON Employees.EmployeeId = EmployeeCTE.ManagerID ) Select E1.EmployeeName, ISNULL(E2.EmployeeName, 'No Boss') as ManagerName From EmployeeCTE E1 LEFT Join EmployeeCTE E2 ON E1.ManagerID = E2.EmployeeId
