java - DB2 中的 JDBC 和 Hibernate 错误 : Connection authorization failure occurred | SQL Error: -99999, SQLState: 42505

Question

大家好，我尝试更新 DB2 表中的一行，但出现错误

java.sql.SQLException: Connection authorization failure occurred.

在 hibernate 状态下我有这个:

    StringBuilder sb = new StringBuilder();

    sb.append("UPDATE Scsret set pollife = 'x' ");
    sb.append("WHERE id = 68197");// test dummy update

    Query query = getCurrentSession().createQuery(sb.toString());

    int update = query.executeUpdate();

并收到此错误

我也尝试使用 Pure Jdbc，但我得到了相同的结果

    StringBuilder sb = new StringBuilder();

    sb.append("UPDATE LSMODDTA.SCSRET SET FEMI  = 20140102 WHERE ID = ");
    sb.append("68196"); //test dummy update

    try {
        PreparedStatement  preparedStatement = conn.prepareStatement(sb.toString());

        int update = preparedStatement.executeUpdate();

        System.out.println(update);



        //System.out.println(update);
    } catch (SQLException e) {
        e.printStackTrace();
    }

并产生此错误

在 SQL 编辑器中运行生成 Hibernate 的查询，并且工作完美

update
        LSMODDTA.SCSRET 
set
        pollife='x' 
where
        id=68196

两个连接具有相同的用户

发生什么事了？

Answer 1

当已建立的连接设置为“readOnly”时，可能会导致此问题(了解更多信息:http://www-01.ibm.com/support/docview.wss?uid=nas8N1016865)。

您可以通过将连接的 readOnly 标志显式设置为 FALSE 来解决此问题:

connection.setReadOnly(false);
