小编raj*_*har的帖子

我在postgres中有一个表格,结构如下

CREATE TABLE rpaul."HK_LOGIN_DETAILS"
(
  "HK_LOGIN_DETAILS_ID" bigint NOT NULL,
  "HK_LOGIN_DETAILS_USERNAME" character varying(10) NOT NULL,
  "HK_LOGIN_DETAILS_PASSWORD" character varying(50) NOT NULL,
  CONSTRAINT "HK_LOGIN_DETAILS_PK" PRIMARY KEY ("HK_LOGIN_DETAILS_ID" ),
  CONSTRAINT "HK_LOGIN_DETAILS_UK" UNIQUE ("HK_LOGIN_DETAILS_USERNAME" )
)

此表的hibernate映射如下所述

<hibernate-mapping package="net.rpaul.projects.homekeeping.domain.login">
    <class name="LoginDetails" table="`HK_LOGIN_DETAILS`">
        <id name="id" column="`HK_LOGIN_DETAILS_ID`" type="long">
            <generator class="assigned" />
        </id>
        <property name="userName" type="string" column="`HK_LOGIN_DETAILS_USERNAME`" not-null="true" />
        <property name="password" type="string" column="`HK_LOGIN_DETAILS_PASSWORD`" not-null="true" />
    </class>
</hibernate-mapping>

在LoginDetails.java中,我将id字段声明为long,userName和password字段声明为String.还是当我尝试执行以下操作时

List list =  getHibernateTemplate().find("from LoginDetails ld where ld.userName = ?", userName);

我明白了

错误:运算符不存在:字符变化= bytea

我没有得到出错的地方.任何帮助,将不胜感激.

我是一名Java开发人员.但是,出于某种原因,我必须借助C#来完成我的任务.我有下面提到的用于创建DLL的C#代码.必须在我的Java程序中使用该DLL来完成所需的操作.
