Subject USERS and ROLES
Author Anthonie
Good morning,

Another what may seem a silly question regarding roles and users but
a topic that I am unable to resolve. My query regarding Firebird
2.0.1 is this, also giving an example of the current database
(migrating from Paradox to Firebird).

CREATE ROLE SupplierAdmin;
CREATE ROLE CustomerAdmin;

CREATE TABLE suppliers(
supplier_code CHAR(10) NOT NULL,
supplier_name VARCHAR(50) NOT NULL,
...
PRIMARY KEY(supplier_code)
);

CREATE TABLE customers(
customer_code CHAR(10) NOT NULL,
customer_name VARCHAR(50) NOT NULL,
...
PRIMARY KEY(customer_code)
);


GRANT insert, select, update, references ON TABLE suppliers TO ROLE
SupplierAdmin;

GRANT insert, select, update, references ON TABLE customers TO ROLE
CustomerAdmin;

This is easy and within the security database the following users
are defined:

SYSADMIN (the creator of the database)
SYSDBA (administrator installed with Firebird)
IISABO Anthony Booth
IISNLO Naomi Louze
IISMPR Marthin Prentz
IISGBR Graham Bransby

All is well and each person can log onto the database. What I
understand is that the ROLES are specific to the database where they
are created (which makes sense) and also the options as given by the
GRANT command.

Is is possible to assign a role to the user when the user logs onto
the database, meaning, when IISABO logs onto the database he is
immedialted assigned the role of SupplierAdmin instead of SYSADMIN
connecting to the database and once connected assigns each user
their roles with GRANT SupplierAdmin TO IISABO and so forth?

Thank you in advance.
Anhonie.
