How Do I Insert a Null Value in an Access Database?

When you need to insert a null value into a column in an Access database, you could use "" to indicate a zero-length string. However, a zero-length string is not the same as Null. To insert a Null value, simple pass the keyword Null for the column, as shown in the code example.

  Dim MyConnection
  Dim MyConnectionString
  Dim MySQLStatement

  MyConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
    "Data Source=C:\Databases\WebSite.mdb;User Id=admin;Password="
  MySQLStatement = "INSERT INTO MyTable " & _
      "(Column1, Column2) Values('A Value', null)"
			
  Set MyConnection = Server.CreateObject("ADODB.Connection")
  MyConnection.Open MyConnectionString
  MyConnection.Execute(MySQLStatement)

  MyConnection.Close()
  Set MyConnection = Nothing
  Response.Write("Record inserted successfully")

%>
</body>
