VBA to read data from Access Database

Here’s an example of VBA code that reads data from an Access database file (.mdb or .accdb) using ADO (ActiveX Data Objects):

Sub ReadDataFromAccess()
    Dim conn As Object ' ADODB.Connection
    Dim rs As Object ' ADODB.Recordset
    Dim strSQL As String
    
    ' Specify the path and filename of the Access database file
    Dim dbPath As String
    dbPath = "C:\Path\to\your\Database.accdb"
    
    ' Specify the SQL query to retrieve data from the Access database
    strSQL = "SELECT * FROM TableName" ' Replace TableName with the actual table name or query
    
    ' Create a Connection object
    Set conn = CreateObject("ADODB.Connection")
    
    ' Open the Connection to the Access database
    conn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbPath
    
    ' Create a Recordset object and execute the SQL query
    Set rs = CreateObject("ADODB.Recordset")
    rs.Open strSQL, conn
    
    ' Loop through the recordset and read the data
    If Not rs.EOF Then
        rs.MoveFirst
        Do Until rs.EOF
            ' Read data from the recordset and do something with it
            Dim fieldValue As Variant
            fieldValue = rs.Fields("FieldName").Value ' Replace FieldName with the actual field name in the table
            MsgBox fieldValue
            
            rs.MoveNext
        Loop
    End If
    
    ' Close the recordset and the connection
    rs.Close
    conn.Close
    
    ' Clean up the objects
    Set rs = Nothing
    Set conn = Nothing
End Sub

In this code, you need to modify the dbPath variable to the actual path and filename of your Access database file. Also, replace "TableName" with the actual name of the table or query you want to retrieve data from. Inside the loop, you can access specific field values by replacing "FieldName" with the actual field name in the table.

When you run this code, it will connect to the Access database using ADO, execute the SQL query, loop through the recordset, read the data from the specified field, and display it in a message box.
