多结果集的存储过程
再来创建一个多结果集的存储过程：
|
create proc [dbo].[sp_multiresultset]
as
set nocount on
select * from customers
select * from employees
|
找到生成的存储过程方法：
|
[Function(Name="dbo.sp_multiresultset")]
public ISingleResult<sp_multiresultsetResult> sp_multiresultset()
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())));
return ((ISingleResult<sp_multiresultsetResult>)(result.ReturnValue));
}
|
由于现在的VS2008会把多结果集存储过程识别为单结果集存储过程（只认识第一个结果集），
我们只能对存储过程方法多小动手术，修改为：
|
[Function(Name="dbo.sp_multiresultset")]
[ResultType(typeof(Customer))]
[ResultType(typeof(Employee))]
public IMultipleResults sp_multiresultset()
{
IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())));
return (IMultipleResults)(result.ReturnValue);
}
|
然后使用下面的代码测试：
|
var 多结果集存储过程 = ctx.sp_multiresultset();
var Customers = 多结果集存储过程.GetResult<Customer>();
var Employees = 多结果集存储过程.GetResult<Employee>();
GridView1.DataSource = from emp in Employees where emp.FirstName.Contains("A") select emp;
GridView1.DataBind();
GridView2.DataSource = from c in Customers where c.CustomerID.StartsWith("A") select c;
GridView2.DataBind()
