A_ODBC_LOGIN indicates the user name under which you want to connect to the database system. Not all data sources require a user login name. Those that do may have case requirements. Check your data source documentation to determine if login is case-sensitive.
To connect to the database with the user name MYNAME, specify one of these in the run time configuration file.
There is no default value for this variable. If no login is specified, none is used.
