Each updated column name in trigger

[sunil divyeshvar]

Hi,

I know by applying new.value <> old.value ,

we can know which column got update bt i hv number of columns in my table so it is not possible to write new.value <> old.value for all columns with IF-ELSE statements.

I need to create log table for my master table , so log table contains only field name(i.e. column name) and old and new value.

Is that possible except new.value <> old.value clause ?

Please reply
Thanks.
