1、在 Postman 中，打开网址：http://api.pcs-api.localhost/v1/plan-config-column-users?login_id=2e368664c41b8bf511bcc9c65d86dbc3&login_tid=685f805f71faedfe215f55bbb01b50c6&filter[config_column_id]=1 ，仅支持字段：config_column_id 的查询，响应如下：

},
...
],
"_links": {
"self": {
"href": "http://api.pcs-api.localhost/v1/plan-config-column-users?login_id=2e368664c41b8bf511bcc9c65d86dbc3&login_tid=685f805f71faedfe215f55bbb01b50c6&filter%5Bconfig_column_id%5D=1&per-page=1023&page=1"
}
},
"_meta": {
"totalCount": 1023,
"pageCount": 1,
"currentPage": 1,
"perPage": 1023
}
}
}
2、SQL 语句如下：
SELECT * FROM `pa_config_column_user` WHERE (`config_column_id` IN (SELECT `pa_config_column`.`id` FROM `pa_config_column` LEFT JOIN `pa_config_column_user` ON `pa_config_column`.`id` = `pa_config_column_user`.`config_column_id` AND `pa_config_column_user`.`user_id` = '8' WHERE (`pa_config_column`.`is_deleted`=0) AND (`pa_config_column`.`status`=1) AND (`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1) AND (`pa_config_column_user`.`user_id`='8') ORDER BY `pa_config_column`.`id` DESC)) AND ((`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1)) AND (`config_column_id`='1') LIMIT 1023
3、现有新的需求，需要支持字段：user_nick 的模糊查询，但是字段：user_nick 不存在于 MySQL ActiveRecord 中，而是存在于 Redis ActiveRecord 中。且 Redis ActiveRecord 不支持 like 操作符。如图1
4、虽然 Redis ActiveRecord 不支持 like 操作符，但是其支持 in 操作符，因此，决定先支持字段：config_column_id 的查询，在此查询结果中，获取所有用户的 user_id(MySQL)，然后基于 in 操作符获取到 Redis ActiveRecord 的所有用户的 user_nick(Redis)。
// 判断用户昵称是否为空，如果不为空，则查询当前分页的框架服务控制台用户列表，然后基于用户昵称模糊搜索
if (!$filterUserNickIsEmpty) {
$likeQuery = clone $query;
$configColumnUserUserIds = $likeQuery->select(['user_id'])->asArray()->column();
print_r($configColumnUserUserIds);
/* 查询当前分页的框架服务控制台用户列表 */ $redisCmcConsoleUserItems = RedisCmcConsoleUser::find()->where(['in', 'id', $configColumnUserUserIds])->indexBy('id')->asArray()->all();
$redisCmcConsoleUserUserNicks = ArrayHelper::getColumn($redisCmcConsoleUserItems, 'user_nick');
print_r($redisCmcConsoleUserUserNicks);
exit;
}
Array
(
[0] => 8
[1] => 29
...
)
Array
(
[8] => 13281105967_nick
[29] => cgl_nick
...
)
5、使用 PHP 过滤类似于 SQL LIKE’％search％’ 的数组中的值，参考问答：filter values from an array similar to SQL LIKE ‘%search%’ using PHP，网址：https://stackoverflow.com/questions/5808923/filter-values-from-an-array-similar-to-sql-like-search-using-php ，如图2
// 判断用户昵称是否为空，如果不为空，则查询当前分页的框架服务控制台用户列表，然后基于用户昵称模糊搜索
if (!$filterUserNickIsEmpty) {
$likeQuery = clone $query;
$configColumnUserUserIds = $likeQuery->select(['user_id'])->asArray()->column();
/* 查询当前分页的框架服务控制台用户列表 */ $redisCmcConsoleUserItems = RedisCmcConsoleUser::find()->where(['in', 'id', $configColumnUserUserIds])->indexBy('id')->asArray()->all();
$redisCmcConsoleUserUserNicks = ArrayHelper::getColumn($redisCmcConsoleUserItems, 'user_nick');
// 使用 PHP 过滤类似于 SQL LIKE'％search％' 的数组中的值
$input = preg_quote($filterUserNick, '~'); // don't forget to quote input string!
$redisCmcConsoleUserLikeUserNicks = preg_grep('~' . $input . '~', $redisCmcConsoleUserUserNicks);
print_r($redisCmcConsoleUserLikeUserNicks);
exit;
}
Array
(
[8] => 13281105967_nick
)
6、在 Postman 中，打开网址：http://api.pcs-api.localhost/v1/plan-config-column-users?login_id=2e368664c41b8bf511bcc9c65d86dbc3&login_tid=685f805f71faedfe215f55bbb01b50c6&filter[config_column_id]=1&filter[user_nick][like]=test ，基于用户昵称模糊搜索获取到：$redisCmcConsoleUserLikeUserNicks，再获取其数组键，作为新的搜索条件，最终生成的 SQL 如下：符合预期，如图3
// 判断用户昵称是否为空，如果不为空，则查询当前分页的框架服务控制台用户列表，然后基于用户昵称模糊搜索
if (!$filterUserNickIsEmpty) {
$likeQuery = clone $query;
$configColumnUserUserIds = $likeQuery->select(['user_id'])->asArray()->column();
/* 查询当前分页的框架服务控制台用户列表 */ $redisCmcConsoleUserItems = RedisCmcConsoleUser::find()->where(['in', 'id', $configColumnUserUserIds])->indexBy('id')->asArray()->all();
$redisCmcConsoleUserUserNicks = ArrayHelper::getColumn($redisCmcConsoleUserItems, 'user_nick');
// 使用 PHP 过滤类似于 SQL LIKE'％search％' 的数组中的值
$input = preg_quote($filterUserNick, '~'); // don't forget to quote input string!
$redisCmcConsoleUserLikeUserNicks = preg_grep('~' . $input . '~', $redisCmcConsoleUserUserNicks);
$query->andWhere(['in', 'user_id', array_keys($redisCmcConsoleUserLikeUserNicks)]);
}
SELECT * FROM `pa_config_column_user` WHERE (`config_column_id` IN (SELECT `pa_config_column`.`id` FROM `pa_config_column` LEFT JOIN `pa_config_column_user` ON `pa_config_column`.`id` = `pa_config_column_user`.`config_column_id` AND `pa_config_column_user`.`user_id` = '8' WHERE (`pa_config_column`.`is_deleted`=0) AND (`pa_config_column`.`status`=1) AND (`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1) AND (`pa_config_column_user`.`user_id`='8') ORDER BY `pa_config_column`.`id` DESC)) AND ((`pa_config_column_user`.`group_id`='015ce30b116ce86058fa6ab4fea4ac63') AND (`pa_config_column_user`.`is_deleted`=0) AND (`pa_config_column_user`.`status`=1)) AND (`config_column_id`='1') AND (`user_id` IN (185, 186, 187, 191, 194, 204, 205, 206, 207, 208, 1051, 1177, 1178, 1180, 1220, 1339)) LIMIT 16
