MySQL ANY and ALL Operators
MySQL ANY and ALL Operators
The ANY and ALL operators in MySQL are used with subqueries to compare a value to one or more values returned by the subquery. They are often used with comparison operators like =, >, <, >=, <=, and !=.
🔹 ANY Operator
-
ANY compares a value to each value in a list or subquery.
-
Returns TRUE if the comparison is TRUE for at least one value.
Syntax:
Example: Find students with marks greater than any student in HR department.
-
✅ Returns students whose marks are greater than at least one student in HR.
🔹 ALL Operator
-
ALL compares a value to all values in a list or subquery.
-
Returns TRUE only if the comparison is TRUE for every value.
Syntax:
Example: Find students with marks greater than all students in IT department.
-
✅ Returns students whose marks are higher than every student in IT.
🔹 Example Table: students
| id | name | dept | marks |
|---|---|---|---|

| 3 | Raj | IT | 76 |
| 4 | Sara | Finance | 92 |
| 5 | Aman | HR | 88 |
