Don't really see the issue here.
What is stopping you changing the datatype?

You can not do it in a single statement, you need to run multiple statements...

ALTER TABLE <TableName> ALTER COLUMN <ColumnName> <Datatype>

I didn't see anything in the Q that says this must be done in code - is that what you meant drtopserv?
To me, it just looked like  case of opening the table in design view and doing the changes.

To expand a bit on what jaiminpsoni wrote:

You'd have to issue individaul commands for EACH DDL query. You can't lump them together the way you can with other databses:

CurrentProject.Connection.Execute "ALTER TABLE <TableName1> ALTER COLUMN <ColumnName1> <Datatype> "
CurrentProject.Connection.Execute "ALTER TABLE <TableName2> ALTER COLUMN <ColumnName2> <Datatype> "
CurrentProject.Connection.Execute  "ALTER TABLE <TableName3> ALTER COLUMN <ColumnName3> <Datatype> "
