Two query cache-related options may be specified in SELECT
statements:
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:
SELECT SQL_CACHE id, name FROM customer;SELECT SQL_NO_CACHE id, name FROM customer;
