Hi,

I'm using FireBird 1.0, I've created a new user "FDMMASTER" and granted him
privileges like the way below for all tables in my project:

GRANT SELECT, UPDATE, DELETE, INSERT, REFERENCES ON GLOB TO FDMMASTER WITH
GRANT OPTION;

Now, when user FDMMASTER tries to execute a Alter Table SQL, he gets the
following ERROR:

EIB_ISCError: ISC ERROR CODE:335544351
ISC ERROR MESSAGE:
unsuccessful metadata update
STORE RDB$RELATION_FIELDS failed
no permission for control access to TABLE GLOB

How can I grant a user the right to Alter Tables??
My SQL.Text:
'Alter Table GLOB ADD BOOL_23 CHAR (1) character set ISO8859_1 DEFAULT ''F''
collate ISO8859_1'

Thanks in advance
