Hi,
there is a question which bother me a lot,can anybody help me?thanks in advance.
i want to know the Production time of the first product on the production line,but how can i calculate it,examples are as follows:
date product working_procedure begintime endtime code
7/8 A 1 7:00:35 7:01:45 1
7/8 A 2 7:01:45 7:03:23 1
7/8 A 3 7:03:23 7:04:35 1
7/8 B 1 7:04:23 7:05:04 2
7/8 A 1 7:05:34 7:06:12 3
7/8 B 2 7:05:05 7:07:23 2
7/8 A 2 7:06:45 7:07:34 3
7/8 A 3 7:08:56 7:09:23 3
7/8 B 3 7:09:34 7:10:23 2
every product has 3 procedures,code means the order of production,i want to get a table like this:
date product timecount(s)
7/8 A 240
7/8 B 360
timecount = endtime - begintime,only need to calculate the first one of every product
Hi, if you want to calculate this in script level, you could try approach like this:
NoConcatenate
timecount:
LOAD
date,
product,
sum(endtime - begintime) *24*60*60 as timecount
RESIDENT your_main_table
WHERE code='1'
GROUP BY date, product;
