我正在尝试使用现有的 DDL 文件创建一个表,该语句非常像这样
CREATE TABLE SYSTEM.LS_Ss_VERSION
(
ID NUMBER (20) NOT NULL ,
SSID NUMBER (20) ,
CONTENT VARCHAR2 (4000 BYTE) ,
CREATEDBY NUMBER (20) ,
CREATED_ON DATE DEFAULT 'NULL'
)
我得到的错误是
SQL Error: ORA-01858: a non-numeric character was found where a numeric was expected
01858. 00000 - "a non-numeric character was found where a numeric was expected"
*Cause: The input data to be converted using a date format model was
incorrect. The input data did not contain a number where a number was
required by the format model.
我已经搜索了谷歌,但无法得到正确的解决方案。请在这里给我建议一个解决方案。
