Here's the question. As a warning, I'm a database newbie just trying to verify claims from others on the project, since there's a bit of uncertainty. I'm sure I'm using the wrong words to describe what I mean.
We've got a database with a number of tables in it, somewhere around 60 or so. There's about, oh, 8 fields on average in a table. It's unknown at present how many records might be stored in any given table, as an upper limit estimate. There's all different value types, the standard ones anyway, being stored.
We're tasked with building a system that propagates change events. That is, whenever any value anywhere changes, we're supposed to generate a message (through our messaging system) to that effect. So, for example, one such message might say that in the MOVEMENT_COMMAND table, in the x_position column, the value changed in the record identified by unique_id 237. So basically the change events have to indicate a particular field, in a particular record, in a particular table (though not necessarily the particular value it changed from or to).
Is this possible to do with triggers, in some feasible manner? The word I've gotten from the developers is 'not really'.

We have a similar requirement where we need to capture the column name and changed value of the table when there is a update on it.
Can you please tell us how we can do this using triggers?
Thanks

I'm just writing to say, I don't really understand your question. I mean, could you word it any less vague? I am currently a computer science major at the University of Vancouver, and maybe I'm dumb, I mean, I feel like an invisible person have the time. Maybe it's because I'm a girl, a young girl at that. Whatever. Just try not to be so wordy next time! All your talk of triggers got me really hot, by the way.
