C#调用自己定义表类型參数

-SQL SERVER生成測试环境:

--创建測试DB
CREATE database Sales;
go
USE Sales
GO
--创建表类型
IF TYPE_ID(‘LocalDT‘) IS NOT NULL
	DROP TYPE LocalDT
GO 
CREATE TYPE LocalDT AS TABLE
(
	ID INT NOT NULL,
	Name NVARCHAR(50)
)
GO
--创建存储过程
IF OBJECT_ID(‘P_DataTable‘,‘P‘) IS NOT NULL
	DROP PROC P_DataTable;
GO

CREATE PROCEDURE P_DataTable
(
	@LocalDT LocalDT READONLY
)
AS
SELECT * FROM @LocalDT
GO

            dr[1] = "Roy";
            dt.Rows.Add(dr);
            SqlConnection thisConnection = new SqlConnection(@"Server=实例名;Database=Sales;User ID=sa;Password=1");
            thisConnection.Open();
