Question

我写了一个查询，它给出了这个错误：

ResultTransformer is not allowed for 'select new' queries

不确定为什么会这样。

StringBuilder q = new StringBuilder();
q.append(" SELECT  DISTINCT new map(p as plan, pei.stateCodeId as state)  ");
q.append(" FROM  PlanEligibilityIndex pei ");

上面的查询是我写新选择的地方，它给出了此错误跟踪。

Answer 1

从选择查询中删除DISTINCT对我有用。

在自定义查询中获取错误““选择新”查询不允许使用ResultTransformer”
