Input / Output data from BLOB column

edited Dec 21, 2010 1:41AM in PL/SQL (MOSC) 2 commentsAnswered
Hi geeks,

I need a help.
 
I have to do 2 Tasks to perform on BLOB:
 
Scenario Brief : We have a table T_Input with a field input_data with BLOB datatype. In that we insert some .xml files through some JAVA interface.Now we want to save this(ese) file(s) on a specified path of our machine through a pl/sql procedure.
 
1.  How to insert into a BLOB field. i.e. how to upload any .xml or .txt file into a BLOB field of some table ??
2.  How to write some file (already there in the BLOB field) on some specified path of our client machine ?? (I will select some BLOB Fields through a SQL query as per the requirement & those files should go & get saved on my hard disk)

Howdy, Stranger!
