If you are more familiar with ADO or DDL, this comparison of field names may help. All versions have this library set by default, except Access 20, so make sure you have the DAO library reference set if you use those versions.ДЇor more information on why you need to use DAO, see Michael Kaplan's blog posting of July 13 2007: What does DAO have that ADO/ADOx/JRO do not?ДЇor an introduction to DAO, see DAO Object Model. This page is a reference for developers, demonstrating how to use the DAO library to programmatically create, delete, modify, and list the objects in Access - the tables, fields, indexes, and relations, queries, and databases - and read or set their properties.ДAO (Data Access Objects) is the native library Microsoft designed to expose the object in Access.
