Answer / Rajendra Kumar Bhilware

1. Atomicity: A transaction is all-or-nothing, meaning that if any part of the transaction fails, the entire transaction fails and the database is left unchanged.
2. Consistency: A transaction ensures that the database remains in a valid state after the transaction completes.
3. Isolation: Concurrent transactions do not interfere with each other. Each transaction is isolated from others.
4. Durability: Once a transaction is committed, the changes made are permanent and will remain even if there is a system failure.

Differentiate between % rowtype and type record.

how to check the 3rd max salary from an employee table? One of the queries used is as follows: select sal from emp a where 3=(select count(distinct(sal)) from emp b where a.sal<=b.sal). Here in the sub query "select count(distinct(sal)) from emp b where a.sal<=b.sal" or "select count(distinct(sal)) from emp b where a.sal=b.sal" should reveal the same number of rows is in't it? Can any one here please explain me how is this query working perfectly. However, there is another query to get the 3rd highest of salaries of employees that logic I can understand. Pls find the query below. "select min(salary) from emp where salary in(select distinct top 3 salary from emp order by salary desc)" Please explain me how "select sal from emp a where 3=(select count(distinct(sal)) from emp b where a.sal<=b.sal)" works source:http://www.allinterview.com/showanswers/33264.html.
