标题: 创建私有临时表报错ORA-14451: unsupported feature with temporar...
说明
私有临时表是18c中新引入的特性，但是在实验时无法正常创建私有临时表，报错

SQL> CREATE PRIVATE TEMPORARY TABLE ora$ptt_my_temp_table (
  id          NUMBER,
  description  VARCHAR2(20)
)
ON COMMIT DROP DEFINITION;
CREATE PRIVATE TEMPORARY TABLE ora$ptt_my_temp_table (
*
ERROR at line 1:

原因
经过不断测试终于找到了原因，就是不要使用sys用户来创建.

1.使用非sys用户

SQL> show pdbs
SP2-0382: The SHOW PDBS command is not available
SQL> show con_name

CON_NAME
------------------------------
LEIPDB
SQL> create private temporary table ora$ptt_a
(
n number
) on commit preserve definition;

Table created.

2.使用system用户

SQL> conn system/oracle
Connected.
SQL> CREATE PRIVATE TEMPORARY TABLE ORA$PTT_sales_ptt_transaction
(time_id    DATE,
   amount_sold  NUMBER(10,2))
   ON COMMIT DROP DEFINITION;

Table created.

3.使用SYS用户
SQL> conn sys/oracle as sysdba
Connected.
SQL> CREATE PRIVATE TEMPORARY TABLE ORA\$PTT_sales_ptt_transaction
(time_id    DATE,
   amount_sold  NUMBER(10,2))
ON COMMIT DROP DEFINITION;
CREATE PRIVATE TEMPORARY TABLE ORA$PTT_sales_ptt_transaction
*
ERROR at line 1:
ORA-14451: unsupported feature with temporary table

4.使用具有sysdba权限的用户
SQL> grant sysdba to lei;

Grant succeeded.

SQL> conn lei/oracle@leipdb
Connected.
SQL> CREATE PRIVATE TEMPORARY TABLE ORA$PTT_test
(time_id    DATE,
   amount_sold  NUMBER(10,2))
   ON COMMIT DROP DEFINITION;

Table created.
