Herewith I am giving solutions to few questions ( you can write these
programs using different ways); similarly you can try for remaining
solutions by your own.
Note: - If you need any other solution, contact me personally.
1) I) Create the following Employee table & insert into it 5 Records EMPLOYEE (NAME, SSN, ADDRESS, SALARY, DOJ, DEPT NAME) Write SQL Queries to a) Delete a record with some DOJ.
b) Update salary of employee who is earning less than 10,000 by 10%.
Ans :- UPDATE EMPLOYEE SET SALARY = SALARY * 1.10 WHERE SALARY<10000
c) Display Name (Capitals), Address (Capitalization) & Dept name (Capitalization) Employee records according to their salary (Less Salary first).
Ans :- SELECT UPPER(NAME), INITCAP(ADDRESS), INITCAP(DEPT_NAME) FROM EMPLOYEE ORDER BY SALARY
II) Write PL/SQL Program to find whether the given number is Palindrome number or not?
2) I) Create the following Employee table & insert into it 5 Records
