我的代码：

queryUpdate="UPDATE cctvcamera SET police_station_name='"
            +list.get(0)+"', url='"+pojo.getUrl()+"',latitude="
            +pojo.getLatitude()+",longitude="
            +pojo.getLongitude()+", junction_name='"
            +pojo.getJunctionName()+"', police_station_id="
            +pojo.getPoliceStationName()
            +" WHERE cameraid="+pojo.getCameraid()+"";

        try {
            list1=getHibernateTemplateDCRMS().executeFind(new HibernateCallback() {

                @Override
                public Object doInHibernate(Session session)
                        throws HibernateException, SQLException {
                    Query q=session.createSQLQuery(queryUpdate);
                    return q.list();

                }


            });

使用Micro soft SQL Server 2008

Answer 1

请使用executeUpdate方法而不是使用executeQuery来执行更新操作;

com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.

Answer 2

在您的代码中，您正在调用query.list()，如果您想在数据库上运行select查询，此方法很有用。

将其替换为executeUpdate，如下所示：

@Override
public Object doInHibernate(Session session) throws HibernateException, SQLException {

    Query q=session.createSQLQuery(queryUpdate);
    return q.executeUpdate();
}

Answer 3

感谢您的回复。

我得到了解决方案，我已经用代码

替换了我的旧代码。

getHibernateTemplateDCRMS（）bulkUpdate（queryUpdate）;

//其中queryUpdate是查询字符串

更新表后无法理解异常
