oracle中utl_raw

4、位操作函数
  FUNCTION bit_and(r1 IN RAW,
                   r2 IN RAW) RETURN RAW;
  FUNCTION bit_or(r1 IN RAW,
                  r2 IN RAW) RETURN RAW;
  FUNCTION bit_xor(r1 IN RAW,
                   r2 IN RAW) RETURN RAW;
如：
select utl_raw.bit_and(‘12344321‘,‘0f‘) from dual;
select utl_raw.bit_or(‘12344321‘,‘0f‘) from dual;
select utl_raw.bit_xor(‘12344321‘,‘0f‘) from dual;
结果分别为：
02344321、1F344321、1D344321
