group by子句中如果带有having子句的话,那having子句中的内容相当于where子句里的内容;简单地可以having子句里的内容是查询条件。追问having count (*) 怎么解释呢?
追答这里其实应该是说要每个分组都要符合以下条件
( count(*) between 100 and 150)
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
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();
