I don't think this is LINQ. If you are using SQL Server try escaping the column name using square brackets: sum([myColumnName]).

If you want to use Linq, please use sentence similar to this one:

C#

var qry = myTable.AsEnumerable().Sum(a=>a.Field< data_type>("FieldName"));

Note, that you need to replace:
data_type with proper data type[^]
and
FieldName with proper field name.

By The Way, you need to know that string is immutable. I'd suggest to use String.Concat[^] method:

C#

mytable.Compute(string.Concat("Sum(", myColumnName , ")"), ""));

Note: if your column name contains space, i'd suggest to use [] around column name to workaround it.
