sql - Extract Table's Data(including BLOB and CLOB Field's Data) from Source Database and import data to Destination Database -

-

regularly extracted (source database) table’s data flat file (.dat) via spooling in sql*plus tool in oracle database , import extracted data destination database (client database , importing client work).

here problem of tables (more 20 tables) having blob , clob fields

example table name: test_blob_clob

id      name    address    blob_col     clob_col ------------------------------------------------------------- 1001   sanjay   chennai   audio file    more 32k text values 1002   ragav    mumbai    pdf file      more 32k text values 1003   vijay    delhi     word file     less 32k text values 1004   sam      nagpur    txt file      more 32k text values

note:

  • in blob_col files loaded in database , files locally kept in server computer (only path has been indicated)
  • i have googled , searched here everywhere seeing single image or audio or pdf file extc has been extracted blob field "select blob l_blob test_blob_clob id = 1005;" in plsql procedure.
  • i dont need single blob/clob data.
  • i need extract blob/clob data related rest of filed combined data

import data in destination database not job, job extract table's data flat file (.dat)

here table created both blob , clob in single table , blob alone in table , clob alone in other table.

please 1 me how need extract table's data blob , clob fields’ has mentioned in example table , need give extracted data client.

thanks sanjay r
