Hi,
   Please explain me is there any difference if i load my files(like gif or any images files) into the data base as text format?
Bcoz,I have loaded my image files in a text format into the database and when i exported it into my local file system the content of the original file(i.e. imported file into DB) and the exported file from the DB are different.
What is the wrong i did?In which format i have to load my file.Is it only for image files or for all types of files(like js,asp,htm etc)
 
Please help me in resolving this issue.
Thanks in advance
Regards,
Sandhya

I would think a data type with the likes of “binary” (bytea?) would be more appropriate.  It’s like trying to upload an image via FTP in ASCII format – it never comes out the same the other end.

hi ...
It’s like trying to upload an image via FTP in ASCII format – it never comes out the same the other end.
Which one you are referring ?You mean
If i load files using lo_import into DB and when i export it and see  the content is different right!!!
But i read in postgres document as bytea is only for small files and not ot store large contents.Am i right?
 
I have already a table which stores all my image files as OID format?Is there any alternative to do?
Whether i need to store only image files in bytea format or all files like(js,asp,htm etc) also....
Please explain me..It is very much needed for me..
Thank you,
sandhya
