后台获取存储过程返回的数据(转)

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        

{            

conn.Open();            

cmd.ExecuteNonQuery();            

iRet = (decimal)cmd.Parameters["@Amount"].Value;        

}        

catch (SqlException ex)        

{           

  throw ex;        

}        

finally        

{            

conn.Close();        

}        

return iRet;    

}
