添加索引

ALTER TABLE temp1 ADD INDEX  id_userId(`userId`);

使用

DROP TABLE IF EXISTS temp1;  
CREATE TEMPORARY TABLE temp1
SELECT A.id,IF(A.status=3,1,0) '实名',IF(A.authStatus=3,1,0) '身份',IF(D.truckId IS NULL,0,1) '车辆',A.createTime,
-- B.`recommendMobile`,C.`mobile`,
CASE WHEN B.recommendMobile IS NULL THEN '无推荐人' 
WHEN B.recommendMobile IS NOT NULL AND C.mobile IS NULL THEN '非地推推荐'
ELSE '地推推荐' END AS recomType  
FROM TopJet560.`user` A
LEFT JOIN TopJet560.recommendRelationship B ON A.id= B.`recommendedUserId`
LEFT JOIN test.`mobile0815` C ON B.`recommendMobile` = C.`mobile`
LEFT JOIN TopJet560.`driverTruckInfo` D ON A.id = D.driverId AND D.auditStatus =2
WHERE A.createTime >= '2017-06-01' AND A.createTime <'2017-07-01' AND A.type =1

ALTER TABLE temp1 ADD INDEX id_userId(`id`);

SELECT * FROM temp1;
