Oracle ORDER BY Clause
In Oracle, ORDER BY Clause is used to sort or re-arrange the records in the result set. The ORDER BY clause is only used with SELECT statement.

Syntax:-
  

    SELECT expressions  FROM tables   WHERE conditions   ORDER BY expression [ ASC | DESC ];   



Example:- We create table named with Employee and insert some records as shown in below:
  
   CREATE TABLE Employee  
    (
    Empcode varchar2(30) primary key,
    Name varchar2(100),
    Age number(5),   
    Salary numeric(10,2),
    Email varchar2(200),   
    State varchar2(100)  
    CONSTRAINT Employee_pk PRIMARY KEY (Empcode)  
    );  


    //Insert some records as shown below:-

Insert into Employee(Empcode,Name,Age,Salary,Email,State) values('Emp1001','Santosh Kumar Singh',22,12000,'s@gmail.com','Bihar')
Insert into Employee(Empcode,Name,Age,Salary,Email,State) values('Emp1002','Reena kumari',25,15000,'r@gmail.com','Bihar')
Insert into Employee(Empcode,Name,Age,Salary,Email,State) values('Emp1003','Anu Singh',21,14000,'a@gmail.com','UP')
Insert into Employee(Empcode,Name,Age,Salary,Email,State) values('Emp1004','Gagan Agrawal',24,11000,'g@gmail.com','Haryana')
Insert into Employee(Empcode,Name,Age,Salary,Email,State) values('Emp1005','Suraj',21,13000,'su@gmail.com','Bihar')
Insert into Employee(Empcode,Name,Age,Salary,Email,State) values('Emp1006','Pramod kumar sah',27,14000,'pk@gmail.com','New Delhi')



Execute the ORDER BY Clause:-
  

select * from Employee order by Name  ASC

select * from Employee order by Name  DESC




Out Put: Accourding to 'ASC'


Out Put: Accourding to 'DESC'
