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

问题

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?

回答1:

You can use SYS_GUID() to generate a GUID, and use it as DEFAULT value of a column:

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

EDIT: See answers to this question for more details.

回答2:

Make char or varchar2 column data type overwise raw to pass future troubles.
