Question

BLOB
suppose i want to insert image into SQL server table.....what would be table design ?
should i write
IMAGE   varchar(50);  // its wrong ..so whats right to put a blob in a column ?

Answer 1

Blobs are a pain. First off there's nothing about
them in the SQL99 standard, so every database handles
them differently.
Worse, whoever wrote JDBC specification doesn't seem
to have understood how they work.
A BLOB/CLOB is functionally very different from a
varable text/binary field, because all that goes into
the database record itself is some kind of reference
number. BLOBs are stored outside the tables
structure, and not normally through SQL. There can be
several references to the same BLOB from different
records and databases don't seem to keep track of use
counts, so you have to delete them explicitly.
For example in the database I'm using at the moment,
Postgresql, The reference is declared as an "OID" and
it's set in a preparedStatement with a setBlob
method. Saddly there's no legitimate way to create a
new Blob object. I've known people create an record
with an empty blob first, then read and update it in
order to get a Blob object.
Some JDBC drivers, you can use a setOutputStream
method, but the specification is pretty vague.Sir,
While an excellent rant I'm not sure what this has to do with the topic at hand which is how to create a table with a BLOB like column in it in MS-SQL. The OP question really has nothing to with Java at all but we try not let such trivialities stop us.
Good rant though. Have thought the same things myself many a time.
Sincerely,
Slappy
