to make sure that when your application requests a connection to your server, it actually works. In detail, we want to know:
FreeTDS can find and read freetds.confservername exists in freetds.confa host property exists for servernamehost can be resolved to a network addressthe server is listening to the port or named instancethe user can log in to the server Each of the above can be confirmed independently with tsql. Once you're sure you can connect and log in, you can run the unit tests to see if the software works as promised.tsqlThe tsql utility is provided as part of FreeTDS expressly for troubleshooting. tsql is superficially similar to an isql, but uses libtds directly, bypassing the client libraries (e.g., DB-Library). It can also report where it looks for freetds.conf and other compile-time settings (with tsql -C).Example 3-2.
