Connect MySQL databse to debian

Hello,
I wont to connect a MySQL database to debian:
I have installed libmyodbc package and after i have configured /etc/odbcinst.ini:

[MySQL] 
Description = MySQL driver 
Driver      = /usr/lib/odbc/libmyodbc.so 
Setup       = /usr/lib/odbc/libodbcmyS.so 

and /etc/odbc.ini :

[MySQL-gestion] 
Description  = MySQL database gestion 
Driver       = MySQL 
Server       = localhost 
Database     = test 
Port         = 3306 
Socket       = 
Option       = 3 
ReadOnly     = N

But after there is two erros when i try the connection whit the command:echo "select 1" | isql -v root-connector

The errors:

[IM002][unixODBC][Driver Manager] Data source not found, and no default driver specfied.
[ISQL]ERROR: Could not SQLConnect

What's the problem?
Thank's for your help
