Answer 1

您在MODIFIED_ON之后错过了一个逗号，但如果没有SQL代码缩进，很难看到它：
您不能将列选择与查询结果混合使用。如果第二个查询返回多行，该怎么办？
您只使用两个参数USER_CODE和USER_NAME，但您的第二个子选择会再添加一个（DESIGNATION_CODE）并且您永远不会提供其值。

由于这两个查询之间没有关联，我认为这是你必须拥有的：

Query mcMasterQuery = session
    .createSQLQuery(
    "SELECT "+
    "   USER_CODE, "+
    "   USER_NAME, "+
    "   USER_SHORT_NAME, "+
    "   PRINT_NAME, "+
    "   USER_PASSWORD, "+
    "   REMARKS, "+
    "   RECORD_ACTIVE, "+
    "   INACTIVE_WEF, "+
    "   CREATED_BY, "+
    "   CREATED_ON, "+
    "   MODIFIED_BY, "+
    "   MODIFIED_ON "+
    "FROM MCUSERMASTER "+
    "WHERE "+
    "   USER_CODE LIKE NVL(:USER_CODE,'%') AND "+
    "   USER_NAME LIKE NVL(:USER_NAME,'%')"
    )
    .addEntity(UserMasterModel.class)
    .setParameter("USER_CODE", roleMasterModel.getUserCode())
    .setParameter("USER_NAME", roleMasterModel.getUserName());

Query mcDesignationQuery = session
    .createSQLQuery(
    "SELECT " +
    "   DESGN_NAME " +
    "FROM MCDESIGNATIONMASTER " +
    "WHERE " +
    "   DESGN_CODE = :DESIGNATION_CODE" 
    )
    .addEntity(UserMasterModel.class)
    .setParameter("DESIGNATION_CODE", designationCode);

当我尝试执行createSQLQuery（）时出现此异常引起：java.sql.SQLException：列名无效
