C#调用SQL Server参数过程传参

-SQL SERVER生成测试环境:

Create database Test;
go
USE [Test]
GO
if OBJECT_ID(‘Tab2‘,‘U‘) is not null
	drop table Tab2
go
CREATE TABLE [dbo].[Tab2](
	[ID] [int] IDENTITY(1,1) NOT NULL,
	[TabID] [int] NOT NULL,
	[Name2] [nvarchar](50) NULL
)
GO
SET IDENTITY_INSERT [dbo].[Tab2] ON
GO
INSERT [dbo].[Tab2] ([ID], [TabID], [Name2]) VALUES (1, 245575913, N‘ID‘)
GO
INSERT [dbo].[Tab2] ([ID], [TabID], [Name2]) VALUES (2, 245575913, N‘name‘)
GO
INSERT [dbo].[Tab2] ([ID], [TabID], [Name2]) VALUES (3, 277576027, N‘ID‘)
GO
INSERT [dbo].[Tab2] ([ID], [TabID], [Name2]) VALUES (4, 277576027, N‘Name2‘)
GO
INSERT [dbo].[Tab2] ([ID], [TabID], [Name2]) VALUES (5, 277576027, N‘TabID‘)
GO
SET IDENTITY_INSERT [dbo].[Tab2] OFF
GO
if OBJECT_ID(‘P2‘,‘P‘) is not null
	drop procedure P2
go
Create procedure P2
(
@StartID int,
@EndID int,
@Rowcount int output
)
as
select * from Tab2 where ID between @StartID and @EndID
set @[email protected]@ROWCOUNT
