Written by SQL Any, All
In SQL, the keywords ANY and ALL are used in combination with comparison operators to perform comparisons against multiple values within a subquery or a set of values.The ANY keyword is used to check if a value matches at least one value in a set or a subquery. It returns true if any of the comparisons within the set or subquery evaluates to true. Here’s an example:
sql
SELECT column_name FROM table_name WHERE column_name = ANY (SELECT value FROM another_table); ALL keyword is used to check if a value matches all values in a set or a subquery. It returns true if all the comparisons within the set or subquery evaluate to true. Here’s an example:sql
SELECT column_name FROM table_name WHERE column_name > ALL (SELECT value FROM another_table); In this example, the query selects all rows from "table_name" where the value in the "column_name" is greater than all the values returned by the subquery.Both ANY and ALL are often used with comparison operators such as =, >, <, <>, <=, >=, etc., to perform conditional filtering based on multiple values or a set of values.
