----------------------------------------------------------
The SQL ANY Operator
The ANY operator:

returns a boolean value as a result

returns TRUE if ANY of the subquery values meet the condition

ANY means that the condition will be true if the operation is true for any of the values in the range.


ANY Syntax
SELECT column_name(s)
FROM table_name
WHERE column_name operator ANY
  (SELECT column_name
  FROM table_name
  WHERE condition);
-----------
The SQL ALL Operator
The ALL operator:

returns a boolean value as a result
returns TRUE if ALL of the subquery values meet the condition
is used with SELECT, WHERE and HAVING statements
ALL means that the condition will be true only if the operation is true for all values in the range. 

ALL Syntax With SELECT

SELECT ALL column_name(s)
FROM table_name
WHERE condition;


ALL Syntax With WHERE or HAVING

SELECT column_name(s)
FROM table_name
WHERE column_name operator ALL
  (SELECT column_name
  FROM table_name
  WHERE condition);


create table student( sname varchar(20), sage int);
