Hibernate createSQLquery()

addScalar 对带小数点的字段名好像不支持

strQuery=queryString.substring("select".length(),iPos);
StringBuffer fieldStr=new StringBuffer();
for(String s :strQuery.split(",")){
String s_s=s.trim().replace(".","_");
fieldStr.append(" ").append(s).append(" as ").append(s_s).append(" ,");
}
fieldStr.delete(fieldStr.length()-1,fieldStr.length());

session.createSQLQuery("select ns.uuid as ns_uuid from Md_Namespace ns ").addScalar("ns_uuid", Hibernate.STRING).list()

带参数查询count

strQuery = "select count(*) " + queryString.substring(iPos);

SQLQuery queryCount = session.createSQLQuery( strQuery); if (parameters != null) { for (int i = 0; i < parameters.length; i++) { queryCount.setParameter(i, parameters[i]); } } queryCount.addScalar("count(*)",Hibernate.INTEGER); totalCount=(Integer)queryCount.uniqueResult();
