Mysql SQL在多个表上选择一个值

我使用6个表来测量传感器

DEVICES
id imei        name
1  123456789   device1

BMP085
id deviceId date        time     pressure altitude tempC tempF
1  1        2014-02-21  20:01:02 000.00   000.00   00.00 00.00

GPS

HIH6130

MINIMU9V2

RASPI

我想选择表BMP085、GPS、HIH6130、MINIMU9V2和RASPI中设备ID=1的所有匹配数据集。应该只显示此设备的数据集。 此外，我想选择表BMP085、GPS、HIH6130、MINIMU9V2和RASPI的所有匹配数据集，这些数据集的日期=2014-02-21，时间>=20:01:00和='20:01:00'

和t2.time您确定您的数据集结果是错误的吗？当您连接许多表时，很可能会在表中重复结果，这会使您的行显示不止一次

检查时：

SELECT t1.imei, t1.name, 
       t2.date, t2.time, t2.pressure, t2.altitude, t2.tempC, t2.tempF
FROM hab_DEVICES t1
LEFT JOIN hab_BMP085 t2 ON ( t1.id = t2.deviceId AND t1.id = 1 )
WHERE   t2.date = '2014-02-21'
    AND t2.time >= '20:01:00'
    AND t2.time <= '20:01:30'

检查这把小提琴：

我假设表2中的时间是“主时间”，但您可以使用对您更有意义的任何时间。

您能用一些数据和表的描述编写一个SQLFIDLE（）吗？找到解决方案会有很大帮助这是我的小提琴，已经包括了Chococroc建议的内部连接：日期是否应该以某种方式相互关联？我每15秒同时记录一次所有传感器的传感器数据，因此我想获得在特定时间点为所有传感器设置的数据集。好的，我做到了，问题是连接键：你还需要包括时间。检查答案中的更新，XDI正在使用内部联接。给定的语句提供了63个数据集。添加GPS表可提供8064个数据集。添加HIH6130表可提供1032192个数据集。除了DEVICES表之外，所有表都有一个关于id、deviceId、日期和时间的索引，其中id是主键。
