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 in SELECT statements:

• SQL_CACHE

  The query result is cached if it is cacheable and the value of the query_cache_type system variable is ON or DEMAND.

• 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:

Press CTRL+C to copy
 
SELECT SQL_CACHE id, name FROM customer;
SELECT SQL_NO_CACHE id, name FROM customer;
