Answer 1

during my tries to adapt this code to my needs, following error occured during compilation of the procedure:
PLS-00201: identifier 'IMAGES.MIME_TYPE' must be declared
here is my procedure:
CREATE OR REPLACE PROCEDURE load_file( file_name VARCHAR2 )
AS file_lob BFILE;
binary_lob BLOB;
mime_type images.mime_type%TYPE;
extension_pos NUMBER;
BEGIN
--Use the extension of the file name to determing the MIME-type 
--The MIME-type for a .pdf file will be application/pdf
extension_pos := INSTR( file_name, '.' );
mime_type := 'application/' || SUBSTR( file_name,extension_pos + 1,LENGTH( file_name ) );
-- Insert a new row into the images table. Get the LOB locator
-- for the newly inserted row
-- we will be using that to insert
-- the content from the file.
INSERT INTO TESTBLOB( blobid, filename, mime_type, content )
VALUES( 1, file_name, mime_type, EMPTY_BLOB() )
RETURNING content INTO binary_lob;
-- Open up the file in the IMAGES directory named file_name,
-- load that file into the newly created LOB locator, and
-- close the file
file_lob := BFILENAME( 'TESTDIRECTORY', file_name );
dbms_lob.fileOpen ( file_lob, dbms_lob.file_readOnly );
dbms_lob.loadFromFile( binary_lob,file_lob,dbms_lob.getLength( file_lob ) );
dbms_lob.fileClose ( file_lob );
END;
how do I have to adjust the declaration of the mime_type variable respectively what does images.mime_type%TYPE mean?
