lambda表达式中如何在group by 后将查询出的字段象sql一样使用as定义一个名 比如select a as C from b

Posted 2023-03-17

参考技术A 直接Select( new 匿名对象 )就行了，比如你想只要Name ， 就Select( new Name = 数据字段)

Lambda表达式 group by having问题

SELECT code,COUNT(*) FROM Account GROUP BY Code having COUNT(*) > 1

我想转换成
list = session.QueryOver<T>()
.Where(expressionWhere)
.OrderBy(expressionOrderBy).Desc
.Skip(skipCount)
.Take(pageSize)
.List();
这种格式的，求大神帮忙

参考技术A 你试试这样写：
var list = (from t in Account //
group t by t.code
into g
select new

code = g.Key,
count = g.Count()
into c
where c.count > 2
select c).ToList();
