异常sql
SELECT
SUM(CASE WHEN cpu_num=0 THEN 0 when(loadavg/cpu_num)<=1 THEN 1 ELSE 0 END) AS load_low
,SUM(CASE WHEN cpu_num=0 THEN 0 when (loadavg/cpu_num)>1 THEN 1 ELSE 0 END) AS load_high
FROM agent_monitor_db.agent_monitor
报除0异常。
单独剩下 load_low 或者 load_high 都不报错
已解决
SELECT
SUM(CASE WHEN cpu_num > 0 and (loadavg/cpu_num)<=1 THEN 1 ELSE 0 END) AS load_low
,SUM(CASE WHEN cpu_num > 0 and (loadavg/cpu_num)>1 THEN 1 ELSE 0 END) AS load_high
FROM agent_monitor_db.agent_monitor。
但是 还是不明白为啥上面的语句会报错
