休眠（HQL）

[英]Hibernate (HQL)

I am working with NetBeans and when I write an HQL query I see some weird results, when I make a query, at the HQL Editor, like this from User , it returns what I expect, but If I write: select a.name from User a , it returns nothing, just types names at the column name query(Char Char Byte Byte) , although it says the number of records. 我正在使用NetBeans，当我编写HQL查询时，在HQL编辑器中进行查询时，我会看到一些奇怪的结果，就像from User ，它返回我期望的结果，但是如果我写了： select a.name from User a ，它什么也不会返回，只是在列名query(Char Char Byte Byte)键入名称，尽管它说记录数。 Anyone has seen this before? 有人看过吗？

When you use HQL as select a.name from User a , it should return String[] assuming a.name is String type. 当您使用HQL作为select a.name from User a ，假设a.name是String类型，它应该返回String[] 。 Please update the result retrieval/iteration accordingly and print the output. 请相应地更新结果检索/迭代并打印输出。 It should be working. 它应该正在工作。
