Обсуждение: Table (or Column?) level permissions

We have some JSP code that accesses a table.  The problem is that some fields will not return results when selected for, nor will they throw exceptions.

My question is: Can certain columns of a table be restricted in terms of who can access them?

The queries are of the form:

SELECT * FROM myTbl WHERE col_A="someValue";

col_A works, but col_B, col_C, etc. don't.

I'm echoing the queries on the webpage, and these queries will work when manually copied into the pgAdmin.

thanks,
jhmast

No, can't be restricted like this.

I can think of views as a solution, just don't include the columns which
you don't want to share. You will have to issue same number of commands
as you would have issued to revoke permissions from certain users.
