sql - Is there a way to create an auto-incrementing Guid Primary Key in an Oracle database?

Question

I mostly work with sql-server (when I do work with databases) and I am trying to learn pl-sql.

Is there any equivalent to sql-server's auto-generated Guid as primary keys in Oracle?

Answer 1

您可以使用SYS_GUID()生成 GUID，并将其用作列的 DEFAULT 值：

CREATE TABLE test_table (
  uid_col RAW(32) DEFAULT SYS_GUID(),
  some_val VARCHAR2(10)
);

Answer 2

使 char 或 varchar2 列数据类型过度原始以传递未来的麻烦。
