Filter data table-error multiple columns

Learn

Hi
I have used Filter data table activity.
Column1=“Standard” or Column1=“Classic” and
Column2=“Image” or Column2=“Gif”

But this will filter only column2 and not column1. If I remove column2 then it will filter column1

Kindly suggest

Hi,

Do you mean as the following?

(Column1=“Standard” or Column1=“Classic”) and (Column2=“Image” or Column2=“Gif”)

If so, I suppose perhaps you should use 2 Filter Datatable activties.

1st Filter Datatable activty is for Column1=“Standard” or Column1=“Classic”
2nd Filter Datatable activty is for Column2=“Image” or Column2=“Gif” and input should be the output of 1st datatable activity.

Hi,

It’s difficult for single filter datatable activity to handle complex logical expression.
We need to use multiple filter datatable activities, loop like For Each or LINQ.
If we want to use Loop and LINQ , it needs to set filter conditions to collection and/or dictionary in advance.

Ok Thank u. One more help. I need to filter the date to previous two days
Now.Adddays(-2).toString(M/dd/yyyy) and format in CSV is *3/14/2000
I am getting zero rows. Anything wrong in my expression

Hi,

Does the data in the csv start with *?
Do you use Contains or EndsWith operation inf the activity?

8

Not * format which I saw in excel.
If i print dt.Row(0).Item(“columnname”).type it will print string

Hi,

We often face data type problem in datatable filtering.
So I recommend to use LINQ in such case as the following.

dt = dt.AsEnumerable.Where(function(r) DateTime.ParseExact(r("column1").toString,"M/dd/yyyy",nothing)=now.AddDays(-2)).CopyToDataTable()

Can you try above?

Hi,

It works good in my environment UiPath 2018.4.7 and 20.4.1CE.
Can you identify which string is invalid?

dt.AsEnumerable.Where(function(r) DateTime.ParseExact(r(“Start Date”).ToString,“M/dd/yyyy”,nothing)=dateToday ).ToArray()

Here I am geeting exception.
