date problems and arithmetic values

josephinetedesc — Tue, 17 Nov 2015 23:41:17 GMT

Hi my problem is that I have date 0 in Crystal reports coming in as 01/01/1800

Qlikview is recognising the date:

so in Qlikview the dates look like this:

my formula is:

if(time4-time3 <0, 0, time4-time3)

if I do not use an if statment I get this: the same result

I end up with problems when tryting to add the column Time4-time3 in qlikview but not in Excel

Patient	location	time4-time3	Timestamp(time4)	timestamp(time3)
1	AREA a	0.0	11/11/2015 4:45:02 PM	11/11/2015 4:44:04 PM
2	AREA a	1.9	12/11/2015 9:27:54 AM	10/11/2015 11:24:14 AM

My other problem is that when I remove the Patient dimension - I get no data? I do not understand why. I am sure there is a reason ...

What do I need to do in Qlikview to get the aritmetic values?

What is your data source you are using in QV? I think it would be best to already correct the data when reading in.

Could you post some sample data records? And the expected result?

would like something like this: those rows with all hash not to be counted .. They are not counted because either timestamp 3 or timestamp 4 has a value of -35617 - ie nothing has been done yet.

Patient	location	time4-time3	Timestamp(time4)	timestamp(time3)

Ok, but these are not your input records, right? How do these look like?

Maybe it's enough to do something like

LOAD

Patient,

location,

if(time3 >0, time3, NULL() ) as time3,

if(time4 >0, time4, NULL() ) as time4,

...

FROM ...;

This should only take time stamps after Dec 30 1899 into acount.

so would i do a resident load for this? I would still like to see ALL patients.

I will see what I can do at work tomorrow.

Thank you will let you know
