What is the difference between IN
and ANY
operators in SQL?
IN - Equals to Anything in the List
ANY - Compares Value to Each Value Returned by the Sub Query.
ALL - Compares Value To Every Value Returned by the Sub Query.
For Example:
IN:
Display the Details of all the Employees Whose Salaries are Matching with the Least Investments of Departments?
Select Ename, Sal, Deptno
from Emp
Where Sal IN (Select Min(Sal)
From Emp
Group By Deptno);
ANY:
< ANY Means Less Than The Maximum Value in the List.
Get The Details of All Employees Who are Earning Less Than The Highest Earning Employee Controlling Other Emp?
Select Empno, Ename, Job, Sal
From Emp
Where Sal < Any (Select Distinct MGR
From Emp);
> ANY Means More Than The Minimum Value in the List.
Get The Details Of All Emps Who are Earning more than the least paid of Department 10?
Select Empno, Ename, Job, Sal
From Emp
Where Sal > Any (Select Min(Sal)
From Emp
Where Deptno 10);
=ANY is Equivalent to In Operator.
Note: SOME is also used instead of ANY.
SQL>
SQL> -- Use the ANY operator in a WHERE clause to compare a value with any of the values in a list.
SQL>
SQL> -- You must place an =, <>, <, >, <=, or >= operator before ANY.
SQL> SELECT *
2 FROM employee
3 WHERE salary > ANY (2000, 3000, 4000);
For In Operator
SQL> -- Use the IN operator in a WHERE clause to compare a value with any of the values in a list.
SQL> SELECT *
2 FROM employee
3 WHERE salary IN (2000, 3000, 4000);
But with the IN operator you cannot use =, <>, <, >, <=, or >=
IN - It is easy to understand. The query should select only those values which are specified in 'IN' clause. Now, let us understand 'ANY' with a query. ANY means it should be greater or less than any of the values in the list.
Assume a Orders table which has OrderID from 1 to 10
Observer the below query:
select OrderID from Orders
where OrderID < ANY (3,5,7)
The answer to above query is :
OrderID
1,2,3,4,5,6
Explanation :The query says find OrderIDs which are less than ANY of the specified values. So the database searches and includes OrderID as follows:
Is 1<3- Yes hence OrderID 1 is included
Is 2<3- Yes hence OrderID 2 is included
Is 3<3- No, is 3<5 -Yes (as 5 is specified value), hence OrderID 3 is included
Is 4<3- No, is 4<5 -Yes, hence OrderID 4 is included
Is 5<3- No, is 5<5 -No, is 5<7(as 5 is specified value)-Yes hence OrderID 5 is included
Is 6<3- No, is 6<5 -No, is 6<7-Yes hence OrderID 6 is included
Is 7<3- No, is 7<5 -No, is 7<7-No hence OrderID 7 is NOT included as no more values in specified list to compare
Is 8<3- No, is 8<5 -No, is 8<7-No hence OrderID 8 is NOT included as no more values in specified list to compare
Is 9<3- No, is 9<5 -No, is 9<7-No hence OrderID 9 is NOT included as no more values in specified list to compare
Is 9<3- No, is 9<5 -No, is 9<7-No hence OrderID 9 is NOT included as no more values in specified list to compare
Apply the same logic for greater than
select OrderID from Orders
where OrderID > ANY (3,5,7)
The answer to above query is :
OrderID
4,5,6,7,8,9,10
While using all
SELECT empno, sal FROM emp WHERE sal > ALL (2000, 3000, 4000);
EMPNO SAL
7839 5000
It will return result equivalent to query:
SELECT empno, sal FROM emp WHERE sal > 2000 AND sal > 3000 AND sal > 4000;
While using any
SELECT empno, sal FROM emp WHERE sal > ANY (2000, 3000, 4000);
EMPNO SAL
7566 2975
7698 2850
7782 2450
7788 3000
7839 5000
7902 3000
Returns a result same as
SELECT empno, sal FROM emp WHERE sal > 2000 OR sal > 3000 OR sal > 4000;
ANY and ALL OPERATOR IN SQL SERVER 2008R2.
Using the > comparison operator as an example, >ALL means greater than every value--in other words, greater than the maximum value. For example, >ALL (1, 2, 3) means greater than 3. >ANY means greater than at least one value, that is, greater than the minimum. So >ANY (1, 2, 3) means greater than 1.
Similarly, >ANY means that for a row to satisfy the condition specified in the outer query, the value in the column that introduces the subquery must be greater than at least one of the values in the list of values returned by the subquery.
With ANY, you need an operator:
WHERE X > ANY (SELECT Y FROM Z)
With IN, you can't. It's always testing for equality.
