end

Product.where(id: 1).to_sql
# => SELECT `products`.`*` FROM `products` WHERE `id` = 1;

Product.where(id: 1).sql_cache.to_sql
# => SELECT SQL_CACHE `products`.`*` FROM `products` WHERE `id` = 1;

# => SELECT SQL_NO_CACHE `products`.`*` FROM `products` WHERE `id` = 1;

#sql_cache accepts a boolean argument:

# => SELECT SQL_CACHE `products`.`*` FROM `products` WHERE `id` = 1;

Product.where(id: 1).sql_cache(false).to_sql
# => SELECT SQL_NO_CACHE `products`.`*` FROM `products` WHERE `id` = 1;

Product.where(id: 1).sql_cache(nil).to_sql
# => SELECT `products`.`*` FROM `products` WHERE `id` = 1;
