Or does the row have a pointer to an offset in a different chunk? I mean this may be a totally brain dead question, but, how does Informix store a blob in "table" space? Also, what happens when the data grows? What happens to the organization of extents? It's been a while since I have looked at blobs so my alzhimers is kicking in. -Mikey -- #include <std_disclaimer.h> /* Mike Segel (MS385) */ #include <No_Spam.h> #ifdef OFFENDED_BY_CONTENT The author takes no responsibility for this post.
