The TO Clause
The list of one or more users or roles that follows the TO keyword identifies the grantees. You can specify the PUBLIC keyword to grant the specified fragment-level privileges to all users.
You cannot use GRANT FRAGMENT to grant fragment-level privileges to yourself, either directly or through roles.
If you enclose user or role in quotation marks, the name is case sensitive and is stored exactly as you typed it. In an ANSI-compliant database, if you do not use quotation marks around user or around role, the name is stored in uppercase letters.
GRANT FRAGMENT ALL ON customer (part1) TO larry;
GRANT FRAGMENT ALL ON customer (part1, part2) TO millie;
To grant privileges on all fragments of a table to the same user or users, you can use the GRANT statement instead of the GRANT FRAGMENT statement. You can also use the GRANT FRAGMENT statement for this purpose.
GRANT FRAGMENT INSERT ON customer (part1, part2, part3) TO helen; GRANT INSERT ON customer TO helen;
