[Bioperl-l] biosql primary key generation

[Hilmar Lapp]

I do have triggers in Oracle on primary key fields, that's not the 
problem. The problem is controlling the primary key value from the 
/application/ (or library for that matter) such that you can return 
it to the caller who requested the insert.
