Get name of column in a trigger

Within a trigger, is it possible to get the name of the column where data was changed? For example, if a table has columns A, B, C, and D, I want to be able to write a trigger that can determine which column A, B, C, or D the user changed data in and perform some action specific to the column in which the data was changed. I know I can do a row level trigger and select which columns will fire the trigger, but my table is actually quite a bit larger than 4 columns and I would prefer not to have individual update triggers for each column in the table. I am also under the assumption that there is a limit to the number of triggers that can be placed on one table, so, with a rather large table, I won't be able to have a separate trigger for each column.

Thanks,
Mike
