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 ...

Its 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
