MySQL Tutorial
In MySQL, the ANY and ALL operators are used in combination with subqueries to perform comparisons. They allow you to compare a value to a set of values returned by a subquery.
ANY → Returns TRUE if any one value from the subquery satisfies the condition.ALL → Returns TRUE if all values from the subquery satisfy the condition.SELECT column_name FROM table_name WHERE column_name operator ANY ( SELECT column_name FROM another_table WHERE condition );
SELECT column_name FROM table_name WHERE column_name operator ALL ( SELECT column_name FROM another_table WHERE condition );
operator → Can be =, !=, >, <, >=, <=.ANY → Condition is true if at least one value matches the comparison.ALL → Condition is true if all values match the comparison.We have two tables:
