How to remove data separated by a "," and put them in a new table or column in the same table?

Hello,
I have a table with the following data (Using ACCESS and VB.NET)
ROW1: M1, M2, M3
ROW2: MY, MU, MU
ROW3: VF, NH, YH
Is there a way to loop through each row, extract data separated by a "," and put them in another table or a column in that same table?
ROW1: M1
ROW2: M2
ROW3: M3
ROW4: MY
etc..
Thanks,
Victor

In VB.Net retrieve the records from access table and store in DataSet say OldDS.

Split the DataSet each row with ',' separation and iterate for each row and add in a new DataSet NewDS.

Then save this NewDS to new table in access.

you can use recordsets to do that
dim rs as dao.recordset, rsNew as dao.recordset, j, rowArr

set rsNew=currentdb.openrecordset("NewTable")

set rs=currentdb.openrecordset("Table")

rs.movefirst
do until rs.eof

 rowArr=split(rs!fieldName,",")
 for j=0 to ubound(rowarr)
      rsNew.addnew

      rsNew!fieldName=rowArr(j)

      rsNew.update
rs.movenext
loop

rs.close
rsNew.close

forgot the "next"

rs.movenext
loop

rs.close

Thanks for the code. What do I import in my project to use dao? I normally use system.data.oledb with thye followingf code to connect to my database.
Module:
Public ConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\AOPT2002org.mdb;Persist Security Info=True;Jet OLEDB:Database Password=test"
Public objConnection As New OleDb.OleDbConnection(ConnectionString)
Public objDataSet As New DataSet

Form Load:
 Dim objDataAdapter As New OleDb.OleDbDataAdapter("select * from chapter order by chpt", objConnection) 'where country in(SELECT COUNTRY FROM AOP5 WHERE SN like " & "'" & result & "'" & ")order by country", objConnection)
Dim objDataAdapter1 As New OleDb.OleDbDataAdapter("select Country_NAME as NATIONS, country from country ORDER BY country_name", objConnection) 'where country in(SELECT COUNTRY FROM AOP5 WHERE SN like " & "'" & result & "'" & ")order by country", objConnection)
Dim objDataSet As New DataSet
        'fill dataset
        objConnection.Open()
        objDataAdapter.Fill(objDataSet, "Chapter")

You do not need to revert back to DAO to achieve this.

Do you want to store these in separate table? Do you want to avoid duplication?

Yes, I would like to include them in a separate table without duplicates. Thx.

Is it the list of countries or something else?

vcharlesAuthor Commented:
It's a different column, for example:
ROW1: M1, M2, M3
ROW2: MY, MU, MU
ROW3: VF, NH, YH

To do it with .NET code, try this

I am assuming that dTable is already populated with the comma separated values from DB.
Also, dResult is the datatable with 1 column which will store the separated values

Dim CSVs as String
For i As Integer = 0 to dTable.Rows.Count - 1
    CSVs = dTable.Rows(i).Item(0)
    For each value in CSVs.Split(",")
         Dim drow as DataRow = dResult.NewRow()
         drow(0)=value
         dResult.Rows.Add(drow)
    Next
Next


you can then save dResult to DB.

Hi,

I'm not getting an error but the there's no data in the ITEMA column of AOP6C. Goal is to loop through AOP6B string values separated by a "," and poulate ITEMA of AOP6C. Any idea what is wrong with thye code?

Dim ConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\aopt2002org.mdb;Persist Security Info=True;Jet OLEDB:Database Password=testaopupdate"
        Dim da As New OleDb.OleDbDataAdapter("Select ITEMA from AOP6B", ConnectionString)
        Dim da2 As New OleDb.OleDbDataAdapter("Select ITEMA from AOP6C", ConnectionString)

        ' objConnection.Open()
        Dim dTable As New DataTable
        Dim dResult As New DataTable
        Dim CSVs As String
        For i As Integer = 0 To dTable.Rows.Count - 1
            CSVs = dTable.Rows(i).Item(0)
            For Each value In CSVs.Split(",")
                Dim drow As DataRow = dResult.NewRow()
                drow(0) = value
                dResult.Rows.Add(drow)
            Next
        Next
        da2.Fill(dResult)
        da2.Update(dResult)

Thanks,

Victor
