how to save a dataset back to the database

[Asha]

greetings,

i've manually created a dataset which contains data input from users. i
validate the dataset against the business logic and once everything is done,
i would like to save the values in the dataset into the database. the
database has 5 columns and so does my dataset. my dataset has all the same
name field name and datatype as the database. is there a possibility to merge
the dataset in to the database?

i was hoping there would be a way so that i can avoid loop insert. insert
row by row into the database. thanks for help me out..

Use the Update method on the DataAdapter:

Dim conn As New OleDbConnection(strConn)
Try
conn.Open()
' fill dataset from the database
Dim da As New OleDbDataAdapter(strSQL,conn)
Dim ds As New DataSet()
da.Fill(ds)

' do your stuff with the DataSet here

Dim cb As New OleDbCommandBuilder(da)
' update the database with the dataset
da.Update(ds)
Catch ex As Exception
lblError.Text=ex.Message
Finally
conn.Close()
End Try
