Author mydejamail
When I try to grant rights to roles in Firebird, nothing happens.

In some cases the SQL statement to grant the right seems to execute

In some cases I get an error stating that the role does not exist.

In others I get the error that the action is not permissible on
system tables.

Using the WITH GRANT OPTION also gives a syntax error.

Can anyone show me a working example or is my version of Firebird, Win32 simply buggy?
