[GRASS-user] How to JOIN a table to vector layer using MySQL

Hi, I'm using Grass 6.0 (I will use 6.2 soon, but I need to go further 
with 6.0 version until one month).
I would like to join a vector table with external attribute table using 
MySQL.
I created the MySQL Database, and did the v.dbconnect with MySQL drivers.
I did the Join operation with Mysql and it works perfectly. But, when I 
come back in Grass, it is not possible to see the result within the 
attribute table... Joined attributes are not in the table. It seems that 
grass is not able to see results of the joined operation made in Mysql.

Does some body has any suggestion ?

To resume my problem, I can say that I just try to do a join operation 
on vector attribute table, and that this operation seems to be a little 
bit difficult with Grass.

Thanks
