MySQL创建视图和Union all的使用案例



CREATE VIEW netcheck.cpu_mp AS

(SELECT

 cpu.ID AS id,

 cpu.chanel_name AS chanel_name,

 cpu.first_channel AS first_channel,

 cpu.IMG_Url AS IMG_Url,

 cpu.lastModifyTime AS lastModifyTime,

 cpu.SHOW_TIME AS SHOW_TIME,

 cpu.TASK_Id AS TASK_Id,

 cpu.TITLE AS TITLE,

 cpu.URL AS URL,

 cpu.checkSysTaskId AS checkSysTaskId,

 cpu.innerUUID AS innerUUID,

 cpu.isReject AS isReject,

 cpu.scanTime AS scanTime

FROM channel_page_update_result cpu

)

 UNION ALL

(SELECT

  mp.id AS id,

  '' AS chanel_name,

  '' AS first_channel,

  '' AS TITLE,

  mp.imgUrl AS IMG_Url

  ,mp.lastModifyTime AS lastModifyTime,
