我有以下查询:
mysql> select id_sucursal from dw_sucursallookup where sucursal = "Centro"
UNION ALL
select id_sexo from dw_sexolookup where sexo = "Hombre"
UNION ALL
select id_tiempo from dw_tiempolookup where fecha = "2018-06-27" and hora = "noche"
UNION ALL
select id_edad from dw_edadlookup where edad = "41-55"
UNION ALL
select id_tipo_comida from dw_tipo_comidalookup where tipo_de_comida = 'dulce';
其输出如下:
+-------------+
| id_sucursal |
+-------------+
| 2014820869 |
| 2127812561 |
| 2020742459 |
| 49527792 |
| 95944605 |
+-------------+
我想要实现的是将结果转置为:
+-------------+-------------+-------------+-------------+----------------+
| id_sucursal | id_sexo | id_tiempo | id_edad | id_tipo_comida |
+-------------+-------------+-------------+-------------+----------------+
| 2014820869 | 2127812561 | 2020742459 | 49527792 | 95944605 |
+-------------+-------------+-------------+-------------+----------------+
如何在 mysql 中做到这一点?我尝试搜索并找到了一些解决方案,但没有一个像我想要的那样工作。
提前致谢
最佳答案
您可以将 select
与标量子查询结合使用:
select (select id_sucursal from dw_sucursallookup where sucursal = 'Centro') as id_sucursal,
(select id_sexo from dw_sexolookup where sexo = 'Hombre') as id_sexo,
(select id_tiempo from dw_tiempolookup where fecha = '2018-06-27' and hora = 'noche') as id_tiempo
(select id_edad from dw_edadlookup where edad = '41-55') as id_edad,
(select id_tipo_comida from dw_tipo_comidalookup where tipo_de_comida = 'dulce') as tipo_de_comida
