復制代碼 代碼如下:

create proc Employee
@Rowcount int=0 output
as
begin
SELECT * FROM [Northwind].[dbo].[Employees]
set @Rowcount=@@ROWCOUNT
end

復制代碼 代碼如下:

USE [Northwind]
GO
DECLARE @return_value int,
@MyOutput int
EXEC @return_value = [dbo].[Employee]
@Rowcount = @MyOutput OUTPUT
SELECT @MyOutput as N'輸出參數的值'
SELECT 'Return返回的值' = @return_value
GO

復制代碼 代碼如下:

protected void Page_Load(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("server=.;database=Northwind;uid=sa;pwd=1;");
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandText="Employee";
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter para = new SqlParameter("@Rowcount", SqlDbType.Int, 4);
para.Direction = ParameterDirection.Output;
cmd.Parameters.Add(para);
cmd.Parameters.Add("@return_value", SqlDbType.Int, 4);
cmd.Parameters["@return_value"].Direction = ParameterDirection.ReturnValue;
con.Open();
cmd.ExecuteNonQuery();
Response.Write(cmd.Parameters["@Rowcount"].Value.ToString()+"<br/>");
Response.Write(cmd.Parameters["@return_value"].Value.ToString());
}
