using COLUMNS_UPDATED, you can't, i guess you'd have to write your trigger to do each column individually, if that's what you wanted to do:
IF (UPDATE(DESCRIP) )
BEGIN
[same code example]
END
IF (UPDATE(COLUMN2) )
BEGIN
[same code example, just change the column names]
END
IF (UPDATE(COLUMN3) )
BEGIN
[same code example, just change the column names]
END
IF (UPDATE(COLUMN4) )
BEGIN
[same code example, just change the column names]
END
i would think it is easier to simply capture all the changes,and compare on demand for specific queiitons.
