 As SQL is quite vast so I will post interview questions on SQL query in three sets, below is the set-10:

1.     Write An SQL Query To Print Details Of The EMPLOYEEs Whose FIRST_NAME Ends With ‘A’.

Select * from EMPLOYEE where FIRST_NAME like '%a';
2.     Write An SQL Query To Print Details Of The EMPLOYEEs Whose FIRST_NAME Ends With ‘H’ And Contains Six Alphabets.

Select * from EMPLOYEE where FIRST_NAME like '_____h';
3.     Write An SQL Query To Print Details Of The EMPLOYEEs Whose SALARY Lies Between 100000 And 500000.

Select * from EMPLOYEE where SALARY between 100000 and 500000;
4.     Write An SQL Query To Print Details Of The EMPLOYEEs Who Have Joined In Feb’2014.

Select * from EMPLOYEE where year(JOINING_DATE) = 2014 and month(JOINING_DATE) = 2

5.     Write An SQL Query To Fetch EMPLOYEE Names With Salaries >= 50000 And <= 100000.

Select FIRST_NAME, SALARY from EMPLOYEE where SALARY between 50000 And  100000.
