MySQL Query Cache

#query_cache_value # can be any of the following,

query_cache_type = 0 => Caching is disabled 

query_cache_type = 1 => Caching is enabled for all queries 

query_cache_type = 2 => this requires adding the keyword SQL_CACHE to the queries that are to be cached 

If defined “query_cache_type = 2”, then caching will be enabled for the queries which is mentioned SQL_CACHE in it.

Example

SELECT SQL_CACHE column1, column2 FROM table_name;

SELECT SQL_CACHE name, age FROM employees;
