Обсуждение: lo_import doesn't works through ODBC !

  I am successful by trying the following SQL statement in the psql prompt.
  INSERT INTO image (name, raster)
  VALUES ('myimg', lo_import('/var/lib/pgsql/CmpJpg.jpg'));

  Through the psql interface this works properly and i have tried the
  same using the UnixODBC's isql interface as well which again works
  perfectly.

  The problem is, the same SQL statement doesn't works through ODBC, I have
  no clues why it doesn't ?  And when i tried to debug the application
  at some point of time i can notice that "Error while executing the Query
  (non-fatal)" and the return value is STMT_INFO_ONLY

  Any inputs on this problem would be hightly appreciated..

You seem to be using a pretty old driver.

I am running
    PostgreSQL => 7.2.1 on RedHat 7.3
    unixODBC   => 2.2.4
    And I beleive the psqlodbc driver that 'm using is part of the
      default drivers included by unixODBC...

   Should i download and compile a newer version of unixODBC or
   the psqlodbc driver from the postgresql.org ?

   I am stuck coz of this ! Otherwise is it possible to store binary
   data straight in to the database without lo_import/lo_export ?
   I couldn't find any proper literature yet to achieve this. Seems
   bytea does this and i should filter some escape sequences to
   achieve binary data storage.....

   It wld be great if i can get some help here !
