Blank data

evansabres — Fri, 01 Jun 2018 18:43:20 GMT

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?

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/ScriptRegularStatements/NullAsValu…

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
