我有这样的代码...
Query query = em.createQuery("select CM.salesAreaId, SM.salesAreaDesc, count(CM.salesAreaId), sum(CM.openBal), " +
"sum(CM.netSales) from CustomerMaster CM, SalesAreaMaster SM where CM.salesAreaId=SM.salesAreaCode and CM.companyId=SM.companyId" +
" and CM.companyId=:companyId group by CM.salesAreaId, SM.salesAreaDesc");
query.setParameter("companyId", companyId);
List list = query.getResultList();
从上面的代码我怎样才能得到列表值？(list.get()值打印对象)
最佳答案
试试这个
Query query = em.createQuery("select CM.salesAreaId, SM.salesAreaDesc, count(CM.salesAreaId), sum(CM.openBal), " +
"sum(CM.netSales) from CustomerMaster CM, SalesAreaMaster SM where CM.salesAreaId=SM.salesAreaCode and CM.companyId=SM.companyId" +
" and CM.companyId=:companyId group by CM.salesAreaId, SM.salesAreaDesc");
query.setParameter("companyId", companyId);
List list = query.getResultList();
for(Object o : list) {
Object[] obj = (Object[])o;
}
CM.salesAreaId的值应该在obj[0]
关于java - 从列表对象中获取值，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15158765/
