Un módulo de clase de Microsoft Excel que le permite conectarse y manipular las bases de datos de Microsoft Access.

Puede interactuar con una base de datos de MS Access sin ningún conocimiento de MS SQL. La clase de base de datos genera SQL dentro de él y la ejecuta por usted.

Ejemplo de selección de datos de la base de datos:

 ' Let's say you have a MS Access database which has a table called "TestTable":

' ID  text_field  binary_field  number_field
' 1   text-1      Yes           10
' 2   text-2      No            20
' 3   text-3      Yes           30
' 4   text-4      No            40
' 5   text-5      Yes           50


Dim db As New DatabaseUtility
Dim criteriaFields As New Collection, criteriaValues As New Collection, _
        selectionFields As New Collection
Dim results As New ADODB.Recordset
Dim dbName as String, dbPath as String

dbName = "NameOfTheMsAccessDatabase.accdb"
dbPath = "/Path/to/MS/Access/Database/"

' Establish connection with database
Call db.ConnectToDB(dbName, dbPath)

' Enter the fields you want to select in a collection
selectionFields.Add "text_field"
selectionFields.Add "binary_field"
selectionFields.Add "number_field"

' Enter criterias for your query in a collection
criteriaFields.Add "binary_field"
operators.Add "="
criteriaValues.Add "No"
    
criteriaFields.Add "number_field"
operators.Add ">"
criteriaValues.Add "20"

' Get the results in a ADODB.Recordset object
Set results = db.SelectRecords("TestTable", selectionFields, operators, criteriaFields, criteriaValues)

Call db.disconnectFromDB
Set db = Nothing

' results will have
' ID  text_field  binary_field  number_field
' 3   text-3      Yes           30
' 5   text-5      Yes           50

También puede ejecutar su propia consulta
