Thanks for your reply but... I have to change ZSQLMethod's connection_id according to a variable in session (so every user has its own database) while your method (if I understand it) is static. Isn't it?

No its not. Thats whe whole point. You can always look up context.somewhere[variable].yourzsqlmethods.yourzsqlmethod(params...) where variable holds the name of the connection folder. However, your approach isnt recommended even with small number of users your connections to the database will explode to zopethreads x users There was a thread about "per user connection" on this list. Maybe you can join the group of promoters and help the people? Regards Tino
