i am using the following code to create to save my DataTable content to and empty mdb database, so first i create the datata table and when i try to insert data i get the following error: no value given for one or more parameter, now i think this error is caused by the use of Text as mentioned in this link
but i am not sure how to fix it, here is the code and i get the exception in the commented line
Dim cmd = cnn.CreateCommand
cmd.CommandText = "CREATE TABLE productstable(supplierid Integer ,catalogid Integer ,ccode Text ,cname Text,pother2 Text, pother3 Double, cprice Double, rank Integer, rankchange Integer , PD Double, PDP Double , TPD Double, TPDP Double, sprice Double, msprice Double, minprice Double, sopriceDB Double, pother4 Long, usedsuppliermargin Double, cimageurl Text, ccategory Integer, pricetaggroup Byte , spricemargingroup Byte)"
cmd.ExecuteNonQuery()
Dim ocmd As New OleDbCommand("INSERT INTO productstable(supplierid , catalogid, ccode,cname,pother2,pother3,cprice,rank,rankchange,PD,PDP,TPD,TPDP,sprice,msprice,minprice,sopriceDB,pother4,usedsuppliermargin,cimageurl,ccategory,pricetaggroup,spricemargingroup) VALUES (@supplierid , @catalogid, @ccode, @cname, @pother2, @pother3, @cprice, @rank, @rankchange, @PD, @PDP, @TPD, @TPDP, @sprice, @msprice, @minprice, @sopriceDB, @pother4, @usedsuppliermargin,@cimageurl,@ccategory,@pricetaggroup,@spricemargingroup)", cnn)
For i = 0 To mainDatatable.Rows.Count - 1
ocmd.Parameters.Add(New OleDbParameter("@supplierid", mainDatatable.Rows(i)("supplierid")))
ocmd.Parameters.Add(New OleDbParameter("@catalogid", mainDatatable.Rows(i)("catalogid")))
ocmd.Parameters.Add(New OleDbParameter("@ccode", mainDatatable.Rows(i)("ccode")))
ocmd.Parameters.Add(New OleDbParameter("@cname", mainDatatable.Rows(i)("cname")))
ocmd.Parameters.Add(New OleDbParameter("@pother2", mainDatatable.Rows(i)("pother2")))
ocmd.Parameters.Add(New OleDbParameter("@pother3", mainDatatable.Rows(i)("pother3")))
ocmd.Parameters.Add(New OleDbParameter("@cprice", mainDatatable.Rows(i)("cprice")))
ocmd.Parameters.Add(New OleDbParameter("@rank", mainDatatable.Rows(i)("rank")))
ocmd.Parameters.Add(New OleDbParameter("@rankchange", mainDatatable.Rows(i)("rankchange")))
ocmd.Parameters.Add(New OleDbParameter("@PD", mainDatatable.Rows(i)("PD")))
ocmd.Parameters.Add(New OleDbParameter("@PDP", mainDatatable.Rows(i)("PDP")))
ocmd.Parameters.Add(New OleDbParameter("@TPD", mainDatatable.Rows(i)("TPD")))
ocmd.Parameters.Add(New OleDbParameter("@TPDP", mainDatatable.Rows(i)("TPDP")))
ocmd.Parameters.Add(New OleDbParameter("@sprice", mainDatatable.Rows(i)("sprice")))

I don't know how that is working if you left it like in the question , Look at this line
cmd.Parameters.Add(New OleDbParameter("@sopriceDP", mainDatatable.Rows(i)("sopriceDP")))
and compare to Command
..@msprice, @minprice, @sopriceDB, @pother4,..
@sopriceDP
on one and @sopriceDB
on the other

It should be the ocmd
that you have to add parameters and not the cmd
.
ocmd.Parameters.Add(New OleDbParameter("@s....
and one more thing, you have to clear the parameters after the ExecuteNonQuery
For i = 0 To mainDatatable.Rows.Count - 1
ocmd.Parameters.Add(New OleDbParameter("@s....
....
ocmd.ExecuteNonQuery()
ocmd.Parameters.Clear()
Next
