使用联接进行查询调优

如何解决使用联接进行查询调优

我不熟悉查询调优。 无论如何，我可以使用联接调整此查询吗？我正在使用Percona MySQL 5.6。请建议

 SELECT
  COUNT(1) actionLogs
FROM
  (
    SELECT
      uid,`datetime`,subscriber,log
    FROM
      bcmServer.ACTIONLOG
    WHERE
      action_date = DATE(NOW())
  ) d,bcmServer.NETWORKELEMENT ne,bcmServer.SUBSCRIBER sub
  LEFT JOIN bcmServer.SUBDATA sd
    ON sd.macaddress = REPLACE(sub.name,'-','')
WHERE    
  sub.name = d.subscriber
  AND ne.uid = sub.neid
  AND ne.name = 'test'
  AND sd.effectiveend IS NULL

我还提供了查询的表结构和EXPLAIN PLAN

 CREATE TABLE `ACTIONLOG` (
  `uid` bigint(20) NOT NULL AUTO_INCREMENT,`datetime` datetime NOT NULL,`subscriber` varchar(255) NOT NULL,`log` text,`action_date` date DEFAULT NULL,PRIMARY KEY (`uid`),KEY `actionlog_idx_subscriber` (`subscriber`),KEY `action_date_idx` (`action_date`)
) ENGINE=InnoDB AUTO_INCREMENT=58749391 DEFAULT CHARSET=latin1 

这是第二张桌子

CREATE TABLE `NETWORKELEMENT` (
  `uid` bigint(20) NOT NULL AUTO_INCREMENT,`name` varchar(255) NOT NULL,`ipv4Address` int(10) unsigned DEFAULT NULL,`deviceCnt` int(10) unsigned DEFAULT NULL,`emtaCnt` int(10) unsigned DEFAULT NULL,`currentUtilization` bigint(20) unsigned DEFAULT NULL,`lastSysUpTime` int(10) unsigned DEFAULT NULL,`lastCollectionTime` bigint(20) unsigned DEFAULT NULL,UNIQUE KEY `name` (`name`),KEY `name_2` (`name`),KEY `networkelement_idx_name` (`name`)
) ENGINE=InnoDB AUTO_INCREMENT=4994673 DEFAULT CHARSET=latin1

这是第三个表格结构->

CREATE TABLE `SUBSCRIBER` (
  `uid` bigint(20) NOT NULL AUTO_INCREMENT,`acctId` bigint(20) NOT NULL,`neId` bigint(20) NOT NULL,`neUpIfId` bigint(20) NOT NULL,`neDnIfId` bigint(20) NOT NULL,`cpeIpv4Address` int(10) unsigned DEFAULT '0',`docsisMode` int(10) unsigned NOT NULL,`name` varchar(255) DEFAULT NULL,`description` varchar(255) DEFAULT NULL,`service` varchar(255) DEFAULT NULL,UNIQUE KEY `acctId` (`acctId`),KEY `neId_idx` (`neId`),KEY `acctId_2` (`acctId`),KEY `name_idx` (`name`),KEY `subscriber_idx_neid` (`neId`)
) ENGINE=InnoDB AUTO_INCREMENT=17568842 DEFAULT CHARSET=latin1

这是第四个表格结构->

CREATE TABLE `SUBDATA` (
  `CustomerID` varchar(255) DEFAULT NULL,`CompanyName` varchar(255) DEFAULT NULL,`FirstName` varchar(255) DEFAULT NULL,`LastName` varchar(255) DEFAULT NULL,`Address1` varchar(255) DEFAULT NULL,`Address2` varchar(255) DEFAULT NULL,`City` varchar(255) DEFAULT NULL,`State` varchar(255) DEFAULT NULL,`Zip` varchar(255) DEFAULT NULL,`Phone1` varchar(255) DEFAULT NULL,`Email` varchar(255) DEFAULT NULL,`BillingDate` varchar(64) DEFAULT NULL,`BillingAccount` varchar(255) DEFAULT NULL,`AccountStartDate` varchar(255) DEFAULT NULL,`AccountStatus` varchar(255) DEFAULT NULL,`CustomField1` varchar(255) DEFAULT NULL,`CustomField2` varchar(255) DEFAULT NULL,`System` varchar(255) DEFAULT NULL,`PackageName` varchar(255) DEFAULT NULL,`DownloadSpeed` varchar(64) DEFAULT NULL,`UploadSpeed` varchar(64) DEFAULT NULL,`ProvDownloadSpeed` int(11) DEFAULT NULL,`ProvUploadSpeed` int(11) DEFAULT NULL,`RateCode` varchar(255) DEFAULT NULL,`ModemStatus` varchar(255) DEFAULT NULL,`MacAddress` varchar(64) DEFAULT NULL,`accountId` varchar(64) DEFAULT NULL,`serviceCode` varchar(255) DEFAULT NULL,`serviceDesc` varchar(255) DEFAULT NULL,`serviceStatus` varchar(255) DEFAULT NULL,`devAddr` varchar(64) DEFAULT NULL,`locHeadend` varchar(255) DEFAULT NULL,`locLine` varchar(255) DEFAULT NULL,`locNode` varchar(255) DEFAULT NULL,`effectiveStart` date DEFAULT NULL,`effectiveEnd` date DEFAULT NULL,`Exclude` bit(1) DEFAULT NULL,KEY `name_idx` (`MacAddress`),KEY `subdata_idx_effectiveend` (`effectiveEnd`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

然后是查询的解释
