本文章简单的介绍了一篇关于oracle中格式化SYS_GUID()成为标准格式 用法,有需要学习的同事可以看看哦。Oracle里面用RAW(16)保存SYS_GUID()的结果,不过字节顺序(byte order)和标准的GUID不同。如下
标准GUID: 265B113F-0E9D-F44D-A9D4-18BC4D3E836C
RAW(16) : 3F115B26 9D0E 4DF4 A9D4 18BC4D3E836C (实际没有空格,这里是为了显示方便)
为了方便查看,可以用进行简单的转换。
代码如下 | 复制代码 |
create table t(x raw(16)); select x, |
