I need an example of showing how to use OSQL' s -D parameter.

I have defined a system DSN (DCA_Test) using the SQL Server driver. It "tests" successfully.

When I try something like this at the command line, it still asks for user info

osql -D DCA_Test -Q "exec getVM_HostName 'lod123' " -n

Shouldn't it pick up the SQL server, database, user and pswd from the DSN ?...
