respected sir/madam,

    i had to recently encounter of entering the movie
files in a database using the blob datatype.


the problems i faced are:

  1) while creating the table how do i mention the size
of the blob field.  say..

         create table test (name varchar(8),movie
blob());
   how to mention its size....

2) i used the following command to insert a file
,though the query said ok but the select statement
showed a null value.

the command i used is...
   update test set
movie=LOAD_FILE("/home/Hitesh/hitesh.txt") where
name="hitesh";

  3)what exactly is the max_allowed_packet and how to
increase or decrease it.

   4) how to retrive the file from the database.



i did go thru the entire manual but the specific query
eluded me...like i got to know that a file locator is
stored in the database which indirectly connects to
that file and so on.

  i would be glad if my query is quickly answered upon..
thanking you in advance.
hitesh
