Write the same expression separately for selecting each individual column to convert to array.
Create a variable of type System.Collections.Generic.IEnumerable<system.string>
Write an assign to append each array to the Collection e.g. Collection.Append(Array1)
This will provide you a list of string arrays e.g. {[A,B,C],[D,E,F],[G,H,I].
Alternatively if you want to have a single list of individual elements e.g. {A, B, C, D, E, F, G, H, I} then each time you create an individual array from a column use a ForEach Loop through that array and append it to the collection one by one (make sure to change the collection type to string rather than string).
There is no doubt a more elegant way to do this but it will get you there.
Hi @arivu96,
I have tried this code that you give:
DataTableName=DataTableName.Rows.Cast(Of DataRow)().Where(Function(row) Not row.ItemArray.All(Function(field) field Is DBNull.Value Or field.Equals(“”))).CopyToDataTable()
However, I encounter this error:
cast is not a member of system.data.rowcollection
@arivu96 Can you please provide me query to Remove Duplicate record from the Data Table based on 2 Column Names?
With below query I can remove duplicate rows based on 1 column name.
dt.AsEnumerable().GroupBy(Function(i) i.Field(Of String)(“ColumnName”)).Select(Function(g) g.First).CopyToDataTable()
but actually I want to remove duplicate records from the dataTable based on 2 column values so don’t know how to add another column in above query or if you can provide me the query to achieve this would be great.
In this example I want to remove duplicate records based on Column1 and Column3:
Hello Thanks a lot , so helpful ,just like
(From p in dt.Select() where( From q in dt.Select() where q(“name”).Equals(p(“name”)) Select q).ToArray.Count>1 Select p).ToArray.CopyToDataTable()
can i get a code that select where (“name”) is not equal to (“name”)
Remove rows based on particular column is empty.** DataTableName.Select("Convert(column3, System.String)< >''").CopyToDataTable()
or DataTableName.Select("column3< >''").CopyToDataTable()
Here can we use column number in the query instead of column mane
Hi @winnie_toh ,Use Filter data table activity to filter the data table.
Else try below syntax FinalDT1.Select("[Received Date]<='"+LastRunDateDate.ToString("M/dd/yyyy")+"' ").CopyToDataTable()
Thank you so much. I tried different solutions but this one worked: Duplicate records from the same data table if you want the specific column alone. This provides both duplicates. If I only want to show the one duplicate and not both, can your code be modified vs adding another assign activity? Thanks again
(From p in dt.Select() where( From q in dt.Select() where q("ColumnName").Equals(p("ColumnName")) Select q).ToArray.Count>1 Select p).ToArray.CopyToDataTable()
