In your case there is no advantage to using the -connectionstring()- option.
You don't really need to use the -connetionstring()- option for most -odbc-
commands because -odbc- builds the connection string for you. It is not
"obsolete" to use Stata's -odbc- command in the way you are using it.
There are certain cases where a user may want to use certain options/features
of a driver for a connection which are not available through the -odbc-
command's other options, and this is where you use the -connectstring()-
option.
An example of the -connectionstring()- option would be
. odbc query, connectionstring(`"Driver=Microsoft Access Driver (*.mdb, *.accdb)
> ;DBQ=C:\Users\khc\Documents\Northwind.accdb"')
DataSource: ConnectionString
Path : C:\Users\khc\Documents\Northwind.accdb
