From b339801963572c66be886079c222b7fbee5e7334 Mon Sep 17 00:00:00 2001 From: alwayssuper <191763414@qq.com> Date: Mon, 23 Jun 2025 08:38:59 +0800 Subject: [PATCH] fix:iot首页统计中存在的TDengine中的SQL特异性问题：在TDengine中，GROUP BY子句不能直接使用别名。在你的SQL中，你先使用TIMETRUNCATE(ts, 1h) AS time定义了一个别名time，然后在GROUP BY time中使用了这个别名，这在TDengine中是不允许的。 --- yudao-module-iot/yudao-module-iot-biz/src/main/resources/mapper/device/IotDeviceMessageMapper.xml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/yudao-module-iot/yudao-module-iot-biz/src/main/resources/mapper/device/IotDeviceMessageMapper.xml b/yudao-module-iot/yudao-module-iot-biz/src/main/resources/mapper/device/IotDeviceMessageMapper.xml index bc9da9e..deef23b 100644 --- a/yudao-module-iot/yudao-module-iot-biz/src/main/resources/mapper/device/IotDeviceMessageMapper.xml +++ b/yudao-module-iot/yudao-module-iot-biz/src/main/resources/mapper/device/IotDeviceMessageMapper.xml @@ -103,7 +103,7 @@ AND ts <= #{endTime} - GROUP BY time + GROUP BY TIMETRUNCATE(ts, 1h) \ No newline at end of file -- libgit2 0.21.4
