错误原因分析：

-->信息: could not read column value from result set: PTID; 列名无效
说明查询出来的结果集中不包含ptid的值。
原来的代码：

String sql = "select disc from CSM_MID.CFG_PTTYPE where ptid='"+ptId+"'";

List list = this.getSession().createSQLQuery(sql).addEntity(CfgPttype.class).list();
CfgPttype cfgPttypeObj = (CfgPttype)list.get(0);

修改后正确的代码：

String sql = "select * from CSM_MID.CFG_PTTYPE where ptid='"+ptId+"'";

List list = this.getSession().createSQLQuery(sql).addEntity(CfgPttype.class).list();
CfgPttype cfgPttypeObj = (CfgPttype)list.get(0);

这样便运行正常了！
由以上写法可以看出，我们需要在查询的结果集中包含查询条件ptid的值。
