we have an esql-C code which establishes Database connectivity using a structure
EXEC SQL connect to : <database ID>
database ID is in the format Database_Name@Host_name
i wish to know how it is able to establish without us providing username and password. We are currently running this code on a HP-Unix system. Is there some sort of mapping in some system file on our UNIX box, which helps us do this. can some1 elaborate on this?
