8.10.3.2 Query Cache SELECT Options

Note

The query cache is deprecated as of MySQL 5.7.20, and is removed in MySQL 8.0.

Two query cache-related options may be specified inSELECT statements:

• SQL_CACHE
  The query result is cached if it is cacheable and the value of thequery_cache_type system variable is ON orDEMAND.
• SQL_NO_CACHE
  The server does not use the query cache. It neither checks the query cache to see whether the result is already cached, nor does it cache the query result.

Examples:

SELECT SQL_CACHE id, name FROM customer;
SELECT SQL_NO_CACHE id, name FROM customer;
