ORA-02456: The HASH IS column specification must be NUMBER(*,0) ORACLE 报错 故障修复 远程处理

文档解释

ORA-02456: The HASH IS column specification must be NUMBER(*,0)

Cause: The column specification must specify an integer.

Action: Specify the column definition as type NUMBER(precision, 0).

ORA-02456:HASH IS列规范必须是NUMBER( * , 0 )。

官方解释

ORA-02456:HASH IS 列规范必须是 NUMBER( * , 0 ) 。这提醒用户他尝试另外初始化表的HASHIS列的规范不正确。

常见案例

当你查询一个表的数据并试图设置HASH IS列规范时,这是很有可能报这样的错误消息。例如,当你尝试使用CREATE TABLE AS SELECT:

CREATE TABLE NEW_TABLE AS

(SELECT *

FROM MAIN_TABLE

HASHIS 9999);

正常处理方法及步骤

当你收到此错误消息时,你需要重新设置HASHIS表的规范,只接受NUMBER( * , 0 )的规范,将你的查询更正如下:

CREATE TABLE NEW_TABLE AS

(SELECT *

FROM MAIN_TABLE

HASHIS NUMBER (20,0));
