It appears that all ways to directly access an SQL Server database from a VBA project have been deprecated:
What did I miss?
Plain old ODBC. In VBA projects for Office applications other than Access, ODBC via ADO is the most straightforward:
Sub AdoOdbcExample()
Dim con As Object
Set con = CreateObject("ADODB.Connection")
con.Open _
"Driver={SQL Server Native Client 11.0};" & _
"Server=.\SQLEXPRESS;" & _
"Database=myDb;" & _
"Trusted_Connection=yes;"
con.Execute "UPDATE Clients SET FirstName='Gord' WHERE ID=5;"
con.Close
Set con = Nothing
End Sub
For VBA projects in Access, we also have the option to use ODBC linked tables and pass-through queries via ACE DAO like we always have
Sub DaoOdbcExample()
Dim cdb As DAO.Database, qdf As DAO.QueryDef
Set cdb = CurrentDb
Set qdf = cdb.CreateQueryDef("")
qdf.Connect = "ODBC;" & _
"Driver={SQL Server Native Client 11.0};" & _
"Server=.\SQLEXPRESS;" & _
"Database=myDb;" & _
"Trusted_Connection=yes;"
qdf.sql = "UPDATE Clients SET FirstName='Gord' WHERE ID=5;"
qdf.ReturnsRecords = False
qdf.Execute dbFailOnError
Set qdf = Nothing
Set cdb = Nothing
End Sub
Notes:
SQL Server Native Client 11.0 is the version that ships with SQL Server 2014 (ref: here).
The cited list of Obsolete Data Access Technologies says "DAO 3.6 is the final version of this technology. It will not be available on the 64-bit Windows operating system.". That refers to Jet DAO ("Microsoft DAO 3.6 Object Library"). ACE DAO ("Microsoft Office 14.0 Access database engine Object Library") is indeed available to 64-bit applications if the 64-bit version of the Access Database Engine is installed.
