Hello,

          Blobs stores
large amount can you please tell me what is the limit i.e hw many kb of
data can it store ? say 4000k like that.

         For suppose if a
4000kb data can be stored using blob and the data stored in blob is
3600k what about the remaining data? will it allocates all the 4000kb
data or will it allocates only 3600kb data? Like char(100) it will
allocates all 100 bytes in memory and  varchar(100) which is
variable memory?
