试试这个。

select cast(sub.timestring as time) as timeval
,extract(hours from  cast(sub.timestring as time)) as hours
,extract(minutes from  cast(sub.timestring as time)) as minutes
,extract(seconds from  cast(sub.timestring as time)) as seconds
,extract(epoch from  cast(sub.timestring as time)) as totalTimeValueInSeconds
from (select '02:31:12' as timestring) sub
