The same user should be able to read and write in all columns excepted in one (e.g. colums X) of a table in a DB2 data base.
How can I restraint its access rights for the column X, so that it may only read data from X and not write in X anymore? It may further write and read in all other columns of the table.
Is it possible to restraint the access rights starting from a certain date (e.g. from 01st July)?
Many thanks in adavance and have a nice day!
