Oracle 10g Unloading BFILE datatypes

8 RETURN BFILENAME(dir,file);
9 END IF;
10 END;
11 /
Function created.

  1. The get_bfile function can now be used to populate a new table containing a BFILE column.

SQL> CREATE TABLE print_media_int AS
2 SELECT product_id, ad_id,
3 get_bfile (ad_graphic_dir, ad_graphic_file) ad_graphic
4 FROM print_media_xt;
Table created.

  1. If we have done our homework properly, the data in the columns of the newly loaded table should match the data in the columns of the original print_media table.

SQL> SELECT product_id, ad_id,
2 get_dir_name(ad_graphic),
3 get_file_name(ad_graphic)
4 FROM print_media_int
5 MINUS
6 SELECT product_id, ad_id,
7 get_dir_name(ad_graphic),
8 get_file_name(ad_graphic)
9 FROM print_media;
no rows selected
