Hi, I didnot try it that way, since my application was using java and postgresql , i used blob type. But the way you
arelooking is definitely a betteridea to solve the problem for all other database .In SQLServer we use type text for
largedata.
 
If you arrive at solution i would also like knowabout it.

Thanks 
manika
