How to read file to blob variable

Question

I Write so:
fil BFILE;
lobd BLOB;
filename VARCHAR2(255);
filename:='1.doc';
fil:=BFILENAME('DOCS_IN',filename);
dbms_lob.CREATETEMPORARY(lobd,true);
dbms_lob.fileopen(fil, dbms_lob.lob_readonly);
dbms_lob.LOADFROMFILE( lobd,fil,dbms_lob.getlength(fil), 1, 1);
Ошибка:
ORA-22285: non-existent directory or file for GETLENGTH operation
But file was successfully open by dbms_lob.fileopen.

Answer 1

create table temp
key INTEGER,
trash BLOB
create directory hdoc as '/tmp';
--For this example, /tmp is the directory and test.bin is the filename.
--You must ensure that a file exist at that location (/tmp/test.bin) for
--this sample to work. The file and location referenced should be that which
--is on the server.
DECLARE
lobd BLOB;
fils BFILE := BFILENAME('HDOC', 'test.bin');
amt INTEGER;
BEGIN
DBMS_LOB.FILEOPEN(fils, dbms_lob.file_readonly);
amt:=DBMS_LOB.getlength(fils);
insert into temp values (1, empty_blob()) returning trash into lobd;
DBMS_LOB.LOADFROMFILE(lobd, fils, amt);
COMMIT;
DBMS_LOB.FILECLOSE(fils);
END;
