Subject: Using DD to Read Data
from Oracle Datafiles

Hi,

I am using dd to read data out of oracle datafiles from an oracle 9i database
on solaris. I am using the following command:

dd if=/location_to_oracle_datafile_and_file_name.DBF bs=8192 skip=11764 count=8
| strings

I have a table called DEPT, querying dba_extents, I see that its block_id is
11764. It also have 8 blocks assigned to it. Now using the above, I get the
following output:

OPERATIONS

 BOSTON ,

SALES

 CHICAGO ,

RESEARCH

 DALLAS ,

ACCOUNTING

 NEW YORK

Whats missing from here is numeric values. Since I am piping the output to
strings , strings will not print out numerics. Does anyone know how i can use
the method above to successfully read an entire table and print out all its
comments.

Thanks.
