文档解释

ORA-02431: cannot disable constraint (string) – no such constraint

Cause: the named constraint does not exist for this table.

Action: Obvious

此错误表明系统没有指定的约束，而 Oracle 无法为不存在的约束禁用它。

官方解释

本错误消息发生在您尝试禁用不存在的约束时。将错误显示出来：

和 ORA-02431：

ORA-02431：无法禁用约束-没有这样的约束

常见原因：

1. 用户拼写错误，导致输入错误的约束名称。

2. 用户使用已经从数据库中删除的约束。

正常处理方法及步骤

1. 确认您输入的约束名称是否正确。

2. 验证约束是否存在，可执行下面的查询：

SELECT * FROM dba_constraints WHERE constraint_name = ‘[Your Constraint Name]’

3. 如果查询不返回任何数据，则表示约束已被删除。在这种情况下，检查日志以了解约束删除的原因。
