excel_file bytea
}
example
insert into excel_file_upload values(1,file1)
file1 can be any file *.doc,*.xls
How i can do this(with out using java or any other language)
using query?
If you are restricted to psql then I gues the only way is the solution show by Albe - but I guess that only works if the file is on the server.
Some of the GUI SQL tools can handle blob "uploads" from the client. So if you are willing to switch to a different SQL client, this could be done without programming.
My own tool available at http://www.sql-workbench.net can either do that through a GUI dialog or as part of an extended SQL syntax that is of course specific to that application.
