Question

I want to insert a new row into an Access database. I’m looking at doing something like:

oConnection = new Connection('connectionstring') oTable = oCennection.table('Orders') oRow = oTable.NewRow oRow.field('OrderNo')=21 oRow.field('Customer') = 'ABC001' oTable.insert 

Which seems to be a sensible way of doing things to me.

However, All examples I look for on the net seem to insert data by building SQL statements, or by creating a ‘SELECT * From …’, and then using this to create a multitude of objects, one of which appears to allow you to …
– populate an array with the current contents of the table.
– insert a new row into this array.
– update the database with the changes to the array.

What’s the easiest way of using vb.net to insert data into an Access database?
Is there a method I can use that is similar to my pCode above?

Answer 1

This is one way:

cn = New OleDbConnection('Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\emp.mdb;') cn.Open() str = 'insert into table1 values(21,'ABC001')' cmd = New OleDbCommand(str, cn) cmd.ExecuteNonQuery 

I would make a dataset, add a tableadapter connected to the Access database, then let the tableadapter create update/delete/modify for me. Then you just could do like this (assuming your database has a usertable and you mapped that up in the dataset):

    Dim UserDS As New UserDS     Dim UserDA As New UserDSTableAdapters.UsersTableAdapter     Dim NewUser As UserDS.UsersRow = UserDS.Users.NewUsersRow      NewUser.UserName = 'Stefan'     NewUser.LastName = 'Karlsson'      UserDS.User.AddUserRow(NewUser)      UserDA.Update(UserDS.Users)
