DB2 Limit update access to one column in table

Question

I have a DB2 table with column "comments" that I would like to allow a user to have update access to, without giving them update access to the whole table.

I suspect that the answer will involve a view. However, in order to make the view relevant, won't I need to expose the primary key to the view? Won't the user then be able to update the primary key, as well as the "comments" column?

Answer 1

You can limit the scope of UPDATE access by specifying a list of columns.

GRANT UPDATE(comments)
ON TABLE my_table
TO USER some_user;

Grant table, view, or nickname privileges statement
