10 – Recordsets

In this post, we will be taking a look at Recordsets.

Strictly speaking a Recordset is an object available to VBA and Access that encapsulates the functionality and code necessary to interact with the Jet Database Engine and any other data source available via ODBC.  In simple terms it lets you play with data held in tables in Access.

You already know there are tables that contain data in Access, but did you know that VBA cannot directly access these tables? Tables are stored in an arcane fashion quite unlike anything in VBA and we need assistance from the Recordsets object to gloss over the issues surrounding accessing the data.
