Time difference in hours

[android1]

Hi,

I'm trying to calculate the diiference in hours between two date/time columns. When I use DateDiff I am not able to use the two columns below.

Also can use a measure, i feel little faster loading time with this 

TimeDiff = CONVERT(SELECTEDVALUE(Table[Date1],0)-SELECTEDVALUE(Table[Date2],0),DATETIME)

and then change the format to time hh:mm:ss
Cheers

DATEDIFF(TablaHoras[TimeFrom];TablaHoras[TimeTo];HOUR)

[android1]

Thanks for both answers. I'm getting the below error for both;

DateDiff_Big...In PowerBI this function doesnt work.

Your Measure should be look like this:

MeasureName=DateDiff(xxxxxx,xxxxxx,Hour)

[android1]

I'm confused. When I type DateDiff( I don't get the TimeFrom or TimeTo columns for selection in the measure.

If I use a calculated column I do but get the above error.

Hi @android1,

In your scenario, please take a look at @Sean's first reply. You need to create a calculated column instead of measure by clicking "New Column" button. As you mentioned the error occurs when you create a calculated column, would you please share a screenshot about the DAX expression for this column? And which visual do you use to display this calculated column values?

Hi Qiuyun_Yu,

I am using a Table visualisation. Here is the custom column  ->

Hi @android1,

From the image, the custom column DAX expression is correct. And I havn't seen the table visual displays the error you mentioned. Would you mind sharing the .pbix file for us to analyze closely?

Best regrdas,

@android1 You have to create a COLUMN - NOT a Measure!

Look at the picture in my post above - you can't do this as a Measure - that's why the columns are not showing up when you type!

click New Column - then you'll see the columns will show up after you type DATEDIFF

@android1 the error above is datediffBig function change to datediff

[Sean]

@android1 You are creating a Column right? And the function is DATEDIFF

[Sean]

@android1 So you've verified both columns are date/time.

Then maybe you have some start (FROM) times that are after the corresponding end (TO) times.

See if this works - but don't forget that this means some of your data is not in the right order...

Hours = SWITCH( 
            TRUE(), 
               'Table'[TimeFrom]<'Table'[TimeTo], DATEDIFF('Table'[TimeFrom], 'Table'[TimeTo], HOUR),
               'Table'[TimeFrom]>'Table'[TimeTo], DATEDIFF('Table'[TimeTo], 'Table'[TimeFrom], HOUR),
               0 )
