我们都知道在Hibernate中使用createQuery和createSQLQuery的最大区别就是前者是使用hql语句，后者使用的是sql语句 之前在使用createSQLQuery进行select...可能是使用createQuery习惯了，一直没找到错误的原因 原本的代码是这样写的： long count = (Long) getSessionFactory().getCurrentSession().createSQLQuery...debug以下，发现返回值就是BigDecimal类型，无奈只能这么写就没问题了 Query query = getSessionFactory().getCurrentSession() .createSQLQuery
查询标量（简单类型） var db = this.ObjectContainer.Resolve(); var sqlQuery = db.Session.CreateSQLQuery...int>(); 查询单表实体类 var db = this.ObjectContainer.Resolve(); var sqlQuery = db.Session.CreateSQLQuery...*} from products {p} join categories {c} on p.CategoryID = c.CategoryID"; var sqlQuery = db.Session.CreateSQLQuery
Session session = this.getSession(); Query query = null; if("SQL".equals(sqlType)){ query = session.createSQLQuery...public Map getObject(String sql){ Map map = null; try { List object = super.getSession(true).createSQLQuery...getString(String field,String sql){ String val = ""; try { val = (String)super.getSession(true).createSQLQuery...session = this.getSession(); if("SQL".equals(sqlType)){ count = Integer.parseInt((String) session.createSQLQuery...0; try { Session session = this.getSession(); if("SQL".equals(sqlType)){ count = session.createSQLQuery
String sqlOther="select p.id,p.email from profile p,user u where p.user_id=u.id"; sqlQuery=session.createSQLQuery...; sqlQuery=session.createSQLQuery(sqlwenhao); sqlQuery.setInteger(0, new Integer(3)); sqlQuery.addScalar... String sqlquanbu="select {p.*} from profile p,user u where p.user_id=u.id"; sqlQuery=session.createSQLQuery...; sqlQuery=session.createSQLQuery(sqlUpdate); sqlQuery.setString(0, "功夫熊猫2"); sqlQuery.setInteger...; sqlQuery=session.createSQLQuery(sqlDelete); sqlQuery.setInteger(0, new Integer(1)); int rowCountDelete
executeUpdate(); // 推荐 getHibernateTemplate().bulkUpdate(hql, param1, param2); 执行SQL // 不推荐 getSession().createSQLQuery...public Void doInHibernate(Session session) throws HibernateException, SQLException { session.createSQLQuery...doInHibernate(Session session) throws HibernateException, SQLException { Query query = session.createSQLQuery
您可以使用createQuery方法执行HQL查询，使用createSQLQuery方法执行原生SQL查询，并使用createCriteria方法创建Criteria查询。...query.setParameter("price", 100.0);List products = query.list();// 原生SQL查询SQLQuery sqlQuery = session.createSQLQuery
session=HibernateSessionFactory.getSession(); try{ SQLQuery S=session.createSQLQuery...ArrayList(); try { String sql="select * from emp"; SQLQuery q=session.createSQLQuery
void testFindAll(){ String sql="select * from t_book"; List list =session.createSQLQuery...public void testObject(){ String sql="select * from t_book"; List list = session.createSQLQuery...; List list = session.createSQLQuery(sql).addEntity(Book.class)...(){ String sql="select * from t_book where price>:price"; List list = session.createSQLQuery...public void testPage(){ String sql="select * from t_book"; List list = session.createSQLQuery
session.beginTransaction(); //SQL语句 String sql = "SELECT * FROM person"; //获取SQLQuery对象 SQLQuery sqlQuery = session.createSQLQuery...; //获取SQLQuery对象 SQLQuery sqlQuery = session.createSQLQuery(sql); //添加占位符 sqlQuery.setParameter(0, 3)
Criteria query = session.createCriteria(Note.class); NativeSQL查询 原生的sql语句 SQLQuery query = session.createSQLQuery
废话不多说，直接上代码： 查询所有： SQL： String sql = "select * from t_student"; List list =session.createSQLQuery...list) { System.out.println(student); } //sql语句和我们原生的sql语句一样，查询后的 //createSQLQuery...sql = "select * from t_student order by t_age desc"; //降序，升序为asc List list =session.createSQLQuery
; Query query = session().createSQLQuery(sql.toString()); select 后的字段没有加别名......
sql查询，缺点，不能跨越数据库，一般不适用，除非遇到复杂的sql语句才使用： 核心代码： //sql语句 //SQLQuery sql= session.createSQLQuery...("select * from user "); SQLQuery sql=session.createSQLQuery("select * from user where id...40 //sql语句 41 //把每一行记录封装为对象数组，再添加到list集合中 42 //SQLQuery sql= session.createSQLQuery...("select * from user "); 43 //把每一行记录封装为指定的对象类型 44 SQLQuery sql=session.createSQLQuery
executeNativeUpdate用来执行SQL的更新或者删除语句 session.createQuery(hql) session.createSqlQuery(sql) 最终都是通过
本地SQL查询与HQL查询的用法基本相似，不同的是SQL查询需要使用Session的createSQLQuery(String sql)方法，返回的查询对象为SQLQuery类型。...from Movie m inner join Category c on m.CategoryId=c.Id where c.name=:cname"; SQLQuery query = sess.createSQLQuery...from Movie m inner join Category c on m.CategoryId=c.Id where c.name=:cname"; SQLQuery query = sess.createSQLQuery
StringBuilder sql = new StringBuilder(); //这里开始拼装sql语句 //创建SQLQuery对象 SQLQuery sqlQuery = getSession().createSQLQuery
`county_code` = '").append(countyCode).append("' "); } SQLQuery q = getSession().createSQLQuery(sb.toString
/ public List> findToMapList(String sql) { Query query = getSession().createSQLQuery...find(String sql,Class clazz, Object... param){ Query query = null; query = getSession().createSQLQuery
stu.getName()+"\t"+stu.getAge()+"\t"+stu.getSex()+"\t"+stu.getTelephone()); } View Code SQL语句查询 使用createSQLQuery...Session session=HibernateSessionFactory.getSession(); SQLQuery sqlquery=session.createSQLQuery
u.name,c.contact_name from user u,contract c where u.id = c.id" Query query = session.createSQLQuery
