Dapper.NET 基本多个结果示例
示例
要在单个查询中获取多个网格，请使用该QueryMultiple方法。然后，您可以通过对返回的连续调用顺序检索每个网格GridReader。
var sql = @"select * from Customers where CustomerId = @id
select * from Orders where CustomerId = @id
select * from Returns where CustomerId = @id";
using (var multi = connection.QueryMultiple(sql, new {id=selectedId}))
{
var customer = multi.Read<Customer>().Single();
var orders = multi.Read<Order>().ToList();
var returns = multi.Read<Return>().ToList();
}
