DB2中的JDBC和休眠错误：发生连接授权失败| SQL错误：-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.

在休眠状态下，我有以下内容：

    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();

并得到这个错误

WARN : org.hibernate.engine.jdbc.spi.SqlExceptionHelper - SQL Error: -99999, SQLState: 42505

而且我也尝试使用Pure Jdbc，但是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();
    }

并产生这个错误

 java.sql.SQLException: Connection authorization failure occurred.

在SQL编辑器中运行生成Hibernate的查询，并完美运行

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

两个连接具有相同的用户

这是怎么回事？

Answer 1

当已建立的连接设置为“ readOnly”时，可能会导致此问题（有关更多信息，请访问： 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);
