sqlserver获取存储过程返回值

1.OUPUT参数返回值

CREATE PROCEDURE [dbo].[nb_order_insert](
@o_buyerid int ,
@o_id bigint OUTPUT
)
AS
BEGIN
SET NOCOUNT ON;
BEGIN
INSERT INTO [Order](o_buyerid )
VALUES (@o_buyerid )
SET @o_id = @@IDENTITY
END
END

存储过程中获得方法：

DECLARE @o_buyerid int

DECLARE @o_id bigint

EXEC [nb_order_insert] @o_buyerid,@o_id output

[b]2.RETURN过程返回值

[/b]



CREATE PROCEDURE [dbo].[nb_order_insert](


@o_buyerid int ,


@o_id bigint OUTPUT


)


AS



BEGIN



SET NOCOUNT ON;


IF(EXISTS(SELECT * FROM [Shop] WHERE [s_id] = @o_shopid))


BEGIN



INSERT INTO [Order](o_buyerid )


VALUES (@o_buyerid )


SET @o_id = [b]@@IDENTITY[/b]



RETURN [b]1 — 插入成功返回1


END[/b]



ELSE



RETURN [b]0 — 插入失败返回0


END[/b]

存储过程中的获取方法


DECLARE @o_buyerid int


DECLARE @o_id bigint


DECLARE @result bit


EXEC @result = [nb_order_insert] @o_buyerid ,o_id bigint

3.SELECT 数据集返回值





CREATE PROCEDURE [dbo].[nb_order_select](


@o_id int



)


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


CREATE TABLE [dbo].[Temp](


[o_id] [bigint] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,


[o_buyerid] [int] NOT NULL


)


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 * from openrowset(’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

//存储过程

//Create PROCEDURE MYSQL

// @a int,

// @b int,

// @c int output

//AS

// Set @c = @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 = 20;

MyCommand.Parameters.Add(new SqlParameter("@b", SqlDbType.Int));

MyCommand.Parameters["@b"].Value = 20;

MyCommand.Parameters.Add(new SqlParameter("@c", SqlDbType.Int));

MyCommand.Parameters["@c"].Direction = ParameterDirection.Output;

MyCommand.ExecuteNonQuery();

Response.Write(MyCommand.Parameters["@c"].Value.ToString());

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;
