Consider a database containing a table called Employee with the following records:

• To fetch all records from Employee table where Salary starts with 3 and ends with 0, the query is:

  SELECT * FROM Employee
  WHERE Salary LIKE '3%0';
  

  
  

  This will produce the result as shown below:

  EmpID	Name	City	Age	Salary
  1	John	London	25	3000
  4	Kim	Amsterdam	30	3100
  5	Ramesh	New Delhi	28	3000

• Similarly, to fetch all records from Employee table where Name of the employee starts with 'Jo', the query is:

  SELECT * FROM Employee
  WHERE Name LIKE 'Jo%';
  

  
  

  This will produce the result as shown below:

  EmpID	Name	City	Age	Salary
  1	John	London	25	3000
  3	Jo	Paris	27	2800

• Using NOT LIKE keyword: NOT LIKE keyword is used as the negation of LIKE keyword. For example, to select all records of the Employee table with Name not starting with 'Jo', the following query can be used:

  SELECT * FROM Employee
  WHERE Name NOT LIKE 'Jo%';
  

  
  

  This will produce the result as shown below:

  EmpID	Name	City	Age	Salary
  2	Marry	New York	24	2750

  5	Ramesh	New Delhi	28	3000
