Setting a User Name and Password

Go Up to Using Environment Variables

To set up a default user name and password for use on a PC client, create two environment variables, ISC_USER, and ­ISC_PASSWORD.

Even if ISC_USER and ISC_PASSWORD are set, a different user name and password may be specified in a DPB used as an argument to isc_attach_database(). A user name or password specified in a database parameter buffer overrides the OS environment variables.

Note: Using environment variables in this manner is not secure, and therefore not recommended.
