Mysql 组合两个SQL结果以在具有不同列名的行中形成一个结果集

因为我需要组合两个SQL结果，在结果集中形成一行

我尝试使用

联合

函数。但结果集有两行，其中

opont.*

列完全离开

opanter.*

列。但它应该在结果集中同时包含这两个列。下面是一段代码

SELECT DISTINCT
  `team_member`.`Team_ID` AS oponent_Team_ID,
  `team`.`Founder_ID` AS oponent_Founder_ID,
  `team`.`Team_Logo` AS oponent_Team_Logo,
  `team`.`team_Name` AS oponent_Founder_ID,
  `teams_game_match`.`team_1_id` AS oponent_team_1_id,
  `teams_game_match`.`team_2_id` AS oponent_team_2_id,
  `teams_game_match`.`game_time` AS oponent_game_time,
  `teams_game_match`.`game_date` AS oponent_game_date,
  `teams_game_match`.`game_name` AS oponent_game_name,
  `teams_game_match`.`accept` AS oponent_accept
FROM
  `team_member`
  JOIN `team`
    ON `team_member`.`Team_ID` = `team`.`Team_ID`
  JOIN `teams_game_match`
    ON `teams_game_match`.`team_2_id` = `team`.`Team_ID`
WHERE `teams_game_match`.`team_1_id` = '11'

UNION

SELECT DISTINCT
  `team_member`.`Team_ID` AS opposer_Team_ID,
  `team`.`Founder_ID` AS opposer_Founder_ID,
  `team`.`Team_Logo` AS opposer_Team_Logo,
  `team`.`team_Name` AS opposer_Founder_ID,
  `teams_game_match`.`team_1_id` AS opposer_team_1_id,
  `teams_game_match`.`team_2_id` AS opposer_team_2_id,
  `teams_game_match`.`game_time` AS opposer_game_time,
  `teams_game_match`.`game_date` AS opposer_game_date,
  `teams_game_match`.`game_name` AS opposer_game_name,
  `teams_game_match`.`accept` AS opposer_accept
FROM
  `team_member`
  JOIN `team`
    ON `team_member`.`Team_ID` = `team`.`Team_ID`
  JOIN `teams_game_match`
    ON `teams_game_match`.`team_1_id` = `team`.`Team_ID`
WHERE `teams_game_match`.`team_2_id` = '11'

实际结果：

需要获得结果集中一行与不同列名组合的结果。让我知道除此之外还有其他功能吗。

您可以在

select max(case when flag=1 then   oponent_Team_ID end) as oponent_Team_ID,
max(case when flag=0 then   oponent_Team_ID end) as opposer_Team_ID

from
(
SELECT DISTINCT
  `team_member`.`Team_ID` AS oponent_Team_ID,
  `team`.`Founder_ID` AS oponent_Founder_ID,
  `team`.`Team_Logo` AS oponent_Team_Logo,
  `team`.`team_Name` AS oponent_Founder_Name,
  `teams_game_match`.`team_1_id` AS oponent_team_1_id,
  `teams_game_match`.`team_2_id` AS oponent_team_2_id,
  `teams_game_match`.`game_time` AS oponent_game_time,
  `teams_game_match`.`game_date` AS oponent_game_date,
  `teams_game_match`.`game_name` AS oponent_game_name,
  `teams_game_match`.`accept` AS oponent_accept, 1 as flag
FROM
  `team_member`
  JOIN `team`
    ON `team_member`.`Team_ID` = `team`.`Team_ID`
  JOIN `teams_game_match`
    ON `teams_game_match`.`team_2_id` = `team`.`Team_ID`
WHERE `teams_game_match`.`team_1_id` = '11'

UNION

SELECT DISTINCT
  `team_member`.`Team_ID` AS opposer_Team_ID,

  `teams_game_match`.`game_name` AS opposer_game_name,
  `teams_game_match`.`accept` AS opposer_accept,0
FROM
  `team_member`
  JOIN `team`
    ON `team_member`.`Team_ID` = `team`.`Team_ID`

@尼桑斯ॐ, 在“字段列表”中的未知列“反对者团队1\u id”中选择此处获取错误作为

。

@Nishanthॐ, chk now-当您执行union时，就不需要为第二个查询定义列名，所以这就是为什么它最终给出了错误！
