i have a table where column 1 is the starttime and column 2 the stoptime. Now i want to insert in column 3 the delta time.
DataBaseA.Starttime = ["28-Jun-2021 05:05:38"]
DataBaseA.Stoptime = ["28-Jun-2021 05:15:38"]
Where each row has different datetimes.
Need a result like
DataBaseA.Deltatime = ["600"]

SaT = datetime(DataaBaseA.Starttime, 'InputFormat', 'dd-MMM-yyyy HH:mm:ss');
StT = datetime(DataaBaseA.Stoptime, 'InputFormat', 'dd-MMM-yyyy HH:mm:ss');
dt = StT - Sat;
DataBaseA.Deltatime = string( seconds(dt) );

Starttime = "28-Jun-2021 05:05:38";
Stoptime = "28-Jun-2021 05:15:38";
Deltatime = compose("%d", seconds(datetime(Stoptime) - datetime(Starttime)))
Deltatime = "600"
