后台获取存储过程返回的数据(转) - Spider024

公告

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 bigint

2.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

//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

{
