VB6 / Access DAO Add Field to Existing Table/Query I have a VB6 application that uses DAO to read and write MS Access files. Since the program uses Access files exclusives, it was written in DAO instead of ADO. The recordsets within the program are based on queries in the database. I need to add a field to the table and query. I'm sure I can figure out testing for the existence of the field in. My question: How can I add a new field to the table AND query?

Ok, I figured out how to add a field to an existing table with DAO
Now the question is, how do I add the new field "Address2" to existing queries in the database? The database contains a query call "Agency Query." I need to add Address2 to this query.
Thanks for any help.
Set dbsAccess = DBEngine.Workspaces(0).OpenDatabase(dbFile$, False, False)
'Agencies is a table in the Access database
Set td = dbsAccess.TableDefs("Agencies")
'Address2 is the field to be added
Set fd = td.CreateField("Address2", dbText, 50)
td.Fields.Append fd
dbsAccess.CloseNow the question is, how do I add the new field "Address2" to existing queries in the database? The database contains a query call "Agency Query." I need to add Address2 to this query.
Thanks for any help.

Re: VB6 / Access DAO Add Field to Existing Table/Query Nevermind... I figured it out. Using SQL of the QueryDefs overwrites the original query in the database with the new one. This thread can be closed.
Set dbsAccess = DBEngine.Workspaces(0).OpenDatabase(dbFile$, False, False)
Set qd = dbsAccess.QueryDefs("Agency Query")
qd.SQL = "SELECT...
dbsAccess.Close •
