Hi
I have to filter the data>120 from excel. I have used attached logic but it gives following error as the source contains no data row.

Dt. AsEnumerable. Where(function(x) cint(“column name”)) >120). CopyToDatable. Rows. Count.

Please help on this. Hw to resolve this issue.if the data count is 0 I have to print 0.

Thanks in advance

Hey @sayalib

You can use Dt. AsEnumerable. Where(function(x) cint(“column name”)) >120). CopyToDatable this and store to datatable variable new_DT
After that do the if check new_DT.rows.count =0 then there is no data else vice versa.

Cheers @sayalib , let me know if this will work for you.

Hi @shreyash_shirbhate
I have tried that but same error occurred. I have tried in another way and solved that issue.
Create variable(row) as ienuberable datarow collection
Row=Dt. AsEnumerable. Where(function(x) cint(“column name”)) >120)

Then if (row.any)
Then find the counts.

But thanks for the response.

CopyToDataTable Method throws this exception in case of an emtpy filter result and when no rows are returned. We can handle this defensively with an approach described here:

Hi @sayalib

Please try,

Dt.AsEnumerable.Where(function(x) cint(x(“column name”))>120).count

Thanks

Or…
Go more lowcode. Loads if not most of RPA developers are not proficient is using .net expressions in that fashion. (Though it is very powerfull of course)

A simple filter datatable activity will achieve exactly te same.
