Calculate the difference in seconds between two time stamps.

I have used a resident load group by with in my code and I cannot calculate the correct duration in seconds between the start timestamp and end time stamp

Current_Data:

Load

datStart,

datEnd,

""Looking for a line to calculate the difference between datStart & datEnd ******

MachineName as L_Machine_Name

RESIDENT Data

Group by MachineName;

There is no aggregate here, Not sure why you required Group By? Perhaps this.

Current_Data:

Load

datStart,

datEnd,

Interval(datStart-dayEnd,'hh:mm:ss') as NewField,

MachineName as L_Machine_Name

RESIDENT Data

Best Anil, When applicable please mark the correct/appropriate replies as "solution" (you can mark up to 3 "solutions". Please LIKE threads if the provided solution is helpful

Can you tell us the date format your fields has.

Assuming datEnd and datStart are timestamps, the differences in seconds would be:

num(interval(datEnd-datStart, 's'))

You may perhaps not want the actual seconds, but rather keep the standard duration (1 = 1 day) and instead just display the value as seconds.

interval(datEnd-datStart, 's')

Thanks  for the comments.

I created a group by because I wanted a small table by machine... the main table 'data' has 800k rows.

I just wanted to show the last datstart and datend by machine in a small table.

Thanks for the comments.

The num(interval(datEnd-datStart, 's')) works and displays a number but I wanted seconds.


And the interval(datEnd-datStart, 's') doesnt work.


tried multiple things and still cannot get this into seconds.

I typed too fast.

interval(datEnd-datStart, 's')


should display the value in seconds. What does it display for you?

May be:

=sum(datEnd-datStart) * 24 * 60 * 60
