文档解释

ORA-02252: check constraint condition not properly ended

Cause: The specified search condition for the check constraint is not properly ended.

Action: End the condition properly.

这是一个由Oracle数据库触发的错误,用户尝试为表创建或修改一个检查约束,但在语句结尾处丢失了结束运算符(例如括号)。

官方解释

常见案例

SQL> ALTER TABLE customers

2 ADD CONSTRAINT customers_city_ck CHECK(city = ‘New York’

正常处理方法及步骤

SQL> ALTER TABLE customers

2 ADD CONSTRAINT customers_city_ck CHECK (city = ‘New York’);

建议修改后,确保已使用正确的语法指定检查约束的完整语句:

SQL> ALTER TABLE customers

2 ADD CONSTRAINT customers_city_ck CHECK(city = ‘New York’);
