Re: longraw in a trigger HOWTO ?

Since :NEW cannot be used with long(raw), you can use the same method of how to deal with mutating problem, that is using a package including global array, a after insert each row trigger to catch pk, and after insert table trigger to do population. But this method can only handle the data <32000, otherwise you have to use blob, which is recommended.
