CREATE OR REPLACE  PROCEDURE blob_to_file (      p_blob     IN OUT nocopy BLOB,      p_dir      IN VARCHAR2,      p_filename IN VARCHAR2)  AS    l_file utl_file.file_type;    l_buffer RAW(32767);    l_amount binary_integer := 32767;    l_pos      INTEGER           := 1;    l_blob_len INTEGER;  BEGIN    l_blob_len := dbms_lob.getlength(p_blob);    -- Open the destination file.    l_file := utl_file.fopen(p_dir, p_filename,'wb', 32767);    -- Read chunks of the BLOB and write them to the file until complete.    WHILE l_pos <= l_blob_len    LOOP      dbms_lob.READ(p_blob, l_amount, l_pos, l_buffer);      ...
