Blank data

[evansabres]

I have a table called

'FBData', which is from a data source called FBData.csv

The columns in the table include 'Likes' Shares' Comments'

I have an expression in a table that is =sum(likes + shares + comments)

Sometimes, these fields are blank in the data, causing the expression to return a value of 0 (zero). For example, likes=100, shares are blank and comments =50, the expression returns 0 due to the blank.

How can this be fixed?

Had marked this as correct as I thought I had a solution, I was wrong

Hi Evan,

You can use the NullAsValue function when loading the data to replace all your Null values with 0. This shows you how: https://help.qlik.com/en-US/qlikview/November2017/Subsystems/Client/Content/Scripting/ScriptRegularS...

I hope that helps!

In script before you load the table copy following two lines:

NullAsValue *;

SET NullValue = 0;

Load

share,

likes,

comments

From Yourtable

hope this helps

Serina -

Where does this go in my script? I tried loading directly before my load statement and did not correct the situation.

Thanks,

Evan

Maybe you could try

Sum(RangeSum(likes, shares, comments))

hope this helps
