to make sure that when your application requests a connection to your server, it actually works. In detail, we want to know:

http://www.freetds.org/userguide/confirminstall.htm >FreeTDS can find and read freetds.conf

servernamehttp://askubuntu.com/questions/167491/connecting-ms-sql-using-freetds-and-unixodbc-isql-no-default-driver-specified > exists in freetds.conf

a host property exists for servername

host can be resolved to a network address

the server is listening to the port or named instance

the 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 adaptive server connection 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. Show compile-time settings with tsql

$ tsql -C Password: Compile-time settings (established with the "configure" script) Version: freetds v0.1.0 freetds.conf directory: /usr/local/etc MS db-lib source compatibility: no Sybase binary compatibility: no Thread safety: yes iconv library: no TDS version: 7.0 iODBC: no unixodbc: no SSPI "trusted" logins: no Keberos: no
For details on the use of tsql, consult its man page.

servername LookupIf all goes well, the first time you fire up tsql it connects and you can issue your first query. More often, though, the result is less joyous. Listed below for your troubleshooting pleasur
