Hi @anishakotian400

There are multiple ways in which it can be done a couple of them are

DT1.Select("[EmpID]=1").CopyToDataTable

or

DT1.AsEnumerable().Where(function(r) r("EmpID").Equals("1")).CopyToDataTable

or

(From p In DT1.AsEnumerable()
Where
p("EmpID").Equals("1")
Select p
).CopyToDataTable

or you can simply use filter datatable activity

Thanks,
Prankur

Hi,

DT1.AsEnumerable().Where(function(r) r("EmpID").Equals("1")).CopyToDataTable().First().Item("Age").ToString

dtData.AsEnumerable().Where(function(x) x("EmpID").toString.Trim.Equals("12345")).Select(Function (x) x("Age").FirstOrDefault

handling not found case

We do not use CoptToDataTable when we can expect also an empty filter result. In such case CopyToDataTable will throw an exception. FirstOrDefault will return null in the case no matching row was found

@anishakotian400 Try this

Assign Str_Variable = DT2.AsEnumerable().Where(function(r) r(“ID”).Equals(“768341”)).CopyToDataTable.Rows(0)(1).ToString

This will give required Age value 45
