Queue item fields are not exposed this way …you need to use it like this
dt1 = dt1.AsEnumerable.Where(function(p) dt2.AsEnumerable.Any(function(y) y("ColName1").ToString.Equals(p("Colname2").ToString))).CopyToDataTable
dt1 is your first table and dt2 is second
cheers
you can use a linq Expression in an assign activity:
dtUniqueData = DataTable1.AsEnumerable().Where(function(row) Not DataTable2.AsEnumerable().Select(function (r) r.Field(Of String)(“ColumnName”)).Any(function(x) x = row.Field(Of String)(“ColumnName”))).CopyToDataTable()
The brackets could be here and there but this should work.
Please replace ColumnName with your column name.
Thanks
Follow the below workflow to delete the common columns in the datatable1.
- Assign -> Column1 = Datatable1.Columns.Cast(Of DataColumn)().Select(Function(c) c.ColumnName).ToList()
- Assign -> Column2 = Datatable2.Columns.Cast(Of DataColumn)().Select(Function(c) c.ColumnName).ToList()
- Assign -> CommonColumns = Column1.Intersect(Column2).ToList()
Note - Column1,Column2,Common Column variables are in List variable type
Use for each activity to iterate the common columns variable to get the each column which is column.
Use this column names in the delete column activity.
Check the below workflow for better understanding.
