Yes, you can create databases with it: select a provider and then the CREATE_DB operation, click on "test", fill in the values and click on "Perform". I agree that the code is not easily understandable. I've now integrated an example in the gnome-db-demo program. > The documentatino for the prepare_create_database() function needs to > give an example of what you might do next.

Use gda_server_operation_get_value_at() and gda_server_operation_set_value_at() to get and set values for any node path. > perform_create_database().

The process to put this into the documentation should be automated from the files in each provider, and would not work all the time because each provider may alter the parameters in a GdaServerOperation it creates to take into account the database specificities of the database to which it's connected (for example, the choices of tables storage engines in MySQL depends on the database to which one is connected). What's in the documentation is the list of "normalized" named parameters which one may find in a GdaServerOperation; for example the "/DB_DEF_P/DB_NAME", will always be present in a GdaServerOperation for the CREATE DATABASE operation, and corresponds to the name of the database to create. > > Some test code that does something similar is not enough.
