I need to implement a fairly fine grained security model. Probably a bit finer that I can do with the standard ownership functionality. My thinking on this is to create a table that contains the users, and a "permission bit" for each function that they may want to do, vis a vi altering an existing row,or rows, or inserting new rows. Looks relatively straight forward, if fairly time consuming to do. But I would need to know which column(s) a given query would add..alter from the function to implement this via a trigger. looks like I see most of what I need t do this in the docs, but I can't quite figure out if I can get this down to what column(s) a given trigger will modify. Is this possible? -- "They that would give up essential liberty for temporary safety deserve neither liberty nor safety." -- Benjamin Franklin
