How to define and retrieve sequences for SQL Server 2005

[Victor Manuel Rojo Nava]

Hi all,

I'm figuring out how to define a sequence with this amazing framework and
then retrieve its values.
I tried inserting a sequence name in table sequences and after that invoke
the getNextSequenceValue methods for DataBase or DBDatabaseDriverMSSQL but I
always get a null value. Am I doing something wrong? 

Regards,
