milliseconds

[Anonymous]

Dear all,

is there a function in Qlikview to calculate milliseconds, like the function below:

sum(DATEDIFF (MILLISECOND , isnull(START_DATE,0) , isnull(END_DATE,0))) TIMEDURATION

Help please !!

Thanks in advance

Sorry, I don't get what you want.

Time calculations are just floating point operations, like

Time1 - Time2 as TimeDiff

in a load script to get the difference of field values (assuming Time1 and Time2 are correctly interpreted as time values).

You can format the Result using

Interval(TimeDiff,'hh:mm:ss.fff')

[where fff denotes the milliseconds]

First of all, thanks for your replay.

I need to calculate the milliseconds.

I do this:

ceil(num#(text(Interval(TIMEDIFF, 'hh')))*3600 + minute(TIMEDIFF)*60 + second(TIMEDIFF)) as SECONDS

but I don't know how to calculate milliseconds

I hope I explained a bit better

[MarcoWedel · Accepted solution]

multiplying an interval with 86400 (number of seconds per day) should suffice to get the intervall in seconds.

So your expression

ceil(num#(text(Interval(TIMEDIFF, 'hh')))*3600 + minute(TIMEDIFF)*60 + second(TIMEDIFF)) as SECONDS

simply becomes

TIMEDIFF * 86400 as SECONDS

To get the milliseconds, it would be just

TIMEDIFF * 86400000 as SECONDS

like swuehl already said:

always remember that timestamps and intervals are just floating point numbers with the integer part being full days and the fraction being the hours, minutes and seconds.
