Example:

Consider a database tables called Employee with the following records:

EmpIDNameCityAgeSalary
1JohnLondon253000
2MarryNew York242750
3JoParis272800
4KimAmsterdam303100
5RameshNew Delhi283000
6HuangBeijing282800

  • To delete the records of an employee whose EmpID is 5, the SQL query is:

    DELETE Employee
    WHERE EmpID = 5;
    

    Now the Employee table will contain following records:

    EmpIDNameCityAgeSalary
    1JohnLondon253000
