can we write stored function in out parameters? how to call
through select statement? how to RETURN more than one
value plz give the exmple?
------
We can write stored function with both IN and OUT parameters.
We can call from select statement only if there is no OUT parameter in it, and that too the called function should not modify the table data what is referred in Select statement.
And other condition it should not return multiple values when it is referred in Select statement
In order to return more then one value you have to use OT parameters or return the value as record and loop through the returned values.

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.
