How to get NEXTVAL of a sequence without seq_name.nextval?

Hi, I have a table with clients and a sequid, in this sequid I will put the id of the sequence that corresponds to the client: CREATE TABLE client( name CHAR(20), sequid INT REFERECES syssequences(sequid) ) Every time there is an insert on this table I will create a sequence with the same name as client.name and put the sequence sequid in client.sequid. My question is: In a SQL procedure, how can I obtain the NEXT VALUE for each sequence? Something like this would be perfect: SELECT NEXTVAL INTO m_nextval FROM syssequences WHERE sequid=3 but this doesn't work. Is there any way to call the nextval function other than with sequence_name.nextval? Thanks, Gonzalo
