如何使用Oracle的BFILE
1.创建相应的directory
使用具有足够权限的用处创建directory,具体参考:Using Create directory & UTL_FILE in Oracle

create or replace directory BDUMP_DIR as 
'/opt/oracle/admin/conner/bdump';

2.给相应的用户授权



grant read on directory BDUMP_DIR  to eygle;

3.检查相应的文件是否存在



host ls -l /opt/oracle/admin/conner/bdump/alert_conner.log

4.数据操作



connect eygle/eygle
create table eygle_test (id number, bfiles bfile ); 

insert into eygle_test values ( 1, bfilename ( 'BDUMP_DIR', 'alert_conner.log' ) );

BFILENAME函数用法参考:
