Thread: Image insertion by using BLOB

Hi ALL,
I am trying to insert the image from the client to database by
spicifying the Windows NT machine filepath.
The server(postgresql 7.0)  is situated at the linux.
If filepath is linux m/c's then i can ...
If filepath is winNT then i have Exception saying :

ERROR: lo_import : ca't open unix file "/jigsaw/jigsaw/www/som.gif "
No such file or directory

Query is as follows::
insert into tablename values('som', lo_import('PATH'));

If possible , how ?


-som

lo_import only works on the servers filesystem.

You need to use the fastpath/largeobject api's to send the image over the 
network connection.

There's 2 C & 1 Java examples included in the source showing this.
