ORM的WhereHas 实际执行Sql语句

 * select * from `test_users` where exists
 *   (
 *     select * from `test_user_profiles` 
 *     where `test_users`.`id` = `test_user_profiles`.`user_id`
 *  ) 

优化版

 * select * from `test_users` where `test_users`.`id` in 
 *   (
 *     select `test_user_profiles`.`user_id` from `test_user_profiles` 
 *     where `test_users`.`id` = `test_user_profiles`.`user_id`
 *   )
