使用 UPDATE、SUM 和 EXTRACT 函数从计算字段更新列

Question

I want to update the 'duration_s' column (numeric), so I can obtain the duration in minutes & hours and also obtain velocity, using the given distance traveled.

but first I need to transform ride_length (schema - time) into an integer

so I tried, but I am stuck. this is the query I tried to write:

WITH calc AS (
      SELECT 
      SUM((EXTRACT(HOUR FROM ride_length)*3600)+(EXTRACT(MINUTE FROM ride_length)*60)+EXTRACT(SECOND FROM ride_length)) AS seconds
      FROM `fresh-ocean-357202.Cyclistic.Cyclistic_yearly`
)
UPDATE `fresh-ocean-357202.Cyclistic.Cyclistic_yearly`
SET duration_s = calc.seconds
WHERE TRUE

these field names have NULL are set as NUMERIC as its data type

Answer 1

I already got it. Instead of doing this:

UPDATE `fresh-ocean-357202.Cyclistic.Cyclistic_yearly` 
SET duration_s = SUM((EXTRACT(HOUR FROM ride_length)*3600)+(EXTRACT(MINUTE FROM ride_length)*60)+EXTRACT(SECOND FROM ride_length))
WHERE TRUE

I did this:

UPDATE `fresh-ocean-357202.Cyclistic.Cyclistic_yearly` 
SET duration_s = (EXTRACT(HOUR FROM ride_length)*3600)+(EXTRACT(MINUTE FROM ride_length)*60)+EXTRACT(SECOND FROM ride_length)
WHERE TRUE

I just removed the SUM function into the SET function
