我们正在尝试将JSON字符串保存到定义为CLOB的数据库列中。我们收到以下错误：

Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-02290: check constraint (MYSCHEMA.MY_JSON_CHK) violated

版本： Weblogic 12.2.1.2

在应用程序ORM层为该列尝试了两种数据类型
java.sql.Clob和oracle.jbo.domain.ClobDomain
通过SQL直接更新效果很好

wrapping of datatype

Answer 1

我尝试将我的EO（ORM）属性从oracle.jbo.ClobDomain切换回纯字符串，并且可以正常工作。
