1.OUPUT参数返回值 例： 向Order表插入一条记录,返回其标识
CREATEPROCEDURE[dbo].[nb_order_insert]( @o_buyeridint , @o_idbigint OUTPUT ) AS BEGIN SET NOCOUNT ON; BEGIN INSERTINTO[Order](o_buyerid ) VALUES (@o_buyerid ) SET@o_id=@@IDENTITY END END存储过程中获得方法：
DECLARE@o_buyeridint DECLARE@o_idbigint EXEC[nb_order_insert]@o_buyerid ,o_id bigint2.RETURN过程返回值
CREATEPROCEDURE[dbo].[nb_order_insert]( @o_buyeridint , @o_idbigint OUTPUT ) AS BEGIN SET NOCOUNT ON; IF(EXISTS(SELECT*FROM[Shop]WHERE[s_id]=@o_shopid)) BEGIN INSERTINTO[Order](o_buyerid ) VALUES (@o_buyerid ) SET@o_id=@@IDENTITY RETURN1 — 插入成功返回1 END ELSE RETURN0 — 插入失败返回0 END存储过程中的获取方法
DECLARE@o_buyeridint DECLARE@o_idbigint DECLARE@resultbit EXEC@result=[nb_order_insert]@o_buyerid ,o_id bigint
3.SELECT 数据集返回值
CREATEPROCEDURE[dbo].[nb_order_select]( @o_idint ) AS BEGIN SET NOCOUNT ON; SELECT o_id,o_buyerid FROM[Order] WHERE o_id =@o_id GO存储过程中的获取方法 （1）、使用临时表的方法
CREATETABLE[dbo].[Temp]( [o_id][bigint]IDENTITY(1,1) NOTFORREPLICATIONNOTNULL, [o_buyerid][int]NOTNULL ) INSERT[Temp]EXEC[nb_order_select]@o_id – 这时 Temp 就是EXEC执行SELECT 后的结果集 SELECT*FROM[Temp] DROP[Temp] — 删除临时表（2）、速度不怎么样.（不推荐）
SELECT*fromopenrowset(’provider_name','Trusted_Connection=yes’,'exec nb_order_select’)1.获取Return返回值
//存储过程
//Create PROCEDURE MYSQL
// @a int,
// @b int
//AS /
/ return @a + @b
//GO
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["LocalSqlServer"].ToString());
conn.Open();
SqlCommand MyCommand = new SqlCommand("MYSQL", conn);
MyCommand.CommandType = CommandType.StoredProcedure;
MyCommand.Parameters.Add(new SqlParameter("@a", SqlDbType.Int));
MyCommand.Parameters["@a"].Value = 10;
MyCommand.Parameters.Add(new SqlParameter("@b", SqlDbType.Int));
MyCommand.Parameters["@b"].Value = 20;
MyCommand.Parameters.Add(new SqlParameter("@return", SqlDbType.Int));
MyCommand.Parameters["@return"].Direction = ParameterDirection.ReturnValue;
MyCommand.ExecuteNonQuery();
Response.Write(MyCommand.Parameters["@return"].Value.ToString());
2.获取Output输出参数值
C#接收存储过程返回值:
public static int User_Add(User us)
{
int iRet;
SqlConnection conn = new SqlConnection(Conn_Str);
SqlCommand cmd = new SqlCommand("User_Add", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@UName", us.UName);
cmd.Parameters.AddWithValue("@UPass", us.UPass);
cmd.Parameters.AddWithValue("@PassQuestion", us.PassQuestion);
cmd.Parameters.AddWithValue("@PassKey", us.PassKey);
cmd.Parameters.AddWithValue("@Email", us.Email);
cmd.Parameters.AddWithValue("@RName", us.RName);
cmd.Parameters.AddWithValue("@Area", us.Area);
cmd.Parameters.AddWithValue("@Address", us.Address);
cmd.Parameters.AddWithValue("@ZipCodes", us.ZipCodes);
cmd.Parameters.AddWithValue("@Phone", us.Phone);
cmd.Parameters.AddWithValue("@QQ", us.QQ);
cmd.Parameters.Add("@RETURN_VALUE", "").Direction = ParameterDirection.ReturnValue;
try
{
conn.Open();
cmd.ExecuteNonQuery();
iRet = (int)cmd.Parameters["@RETURN_VALUE"].Value;
}
catch (SqlException ex)
{
throw ex;
}
finally
{
conn.Close();
}
return iRet;
}
C#接收存储过程输出参数:
public static decimal Cart_UserAmount(int UID)
{
decimal iRet;
SqlConnection conn = new SqlConnection(Conn_Str);
SqlCommand cmd = new SqlCommand("Cart_UserAmount", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@UID", UID);
cmd.Parameters.Add("@Amount", SqlDbType.Decimal).Direction=ParameterDirection.Output;
try
{
conn.Open();
cmd.ExecuteNonQuery();
iRet = (decimal)cmd.Parameters["@Amount"].Value;
}
catch (SqlException ex)
{
throw ex;
}
finally
{
conn.Close();
}
return iRet;
}
