However, it is well known the SQL is a powerful query language with the capability to formulate very complex queries. The straight forward syntax of the SQL SELECT command is often misleading, and generates an impression of simplicity in students’ minds. Students have well verse knowledge of Primary key, Unique key, Foreign key and relationship between them. Through simple SQL statement commands such as CREATE, ALTER, UPDATE, INSERT, DELETE, COMMIT, ROLLBACK, ALTER SESSION and many more, we can modify the database table easily.
