SqlServer获取存储过程返回值的实例，需要的朋友可以参考一下
1.OUPUT参数返回值
复制代码代码如下:
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：
复制代码代码如下:
DECLARE @o_buyerid int
DECLARE @o_id bigint
EXEC [nb_order_insert] @o_buyerid,@o_id output
2.RETURN过程返回值
复制代码代码如下:
@o_id bigint OUTPUT
)
AS
BEGIN
SET NOCOUNT ON;
IF(EXISTS(SELECT * FROM [Shop] WHERE [s_id] = @o_buyerid ))
BEGIN
?INSERT INTO [Order](o_buyerid ) VALUES (@o_buyerid )?
?SET @o_id = @@IDENTITY?
?RETURN 1 — 插入成功返回1?
END?
ELSE?
?RETURN 0 — 插入失败返回0 END
存储过程中的获取方法
复制代码代码如下:
DECLARE @o_buyerid int
DECLARE @o_id bigint
DECLARE @result bit
EXEC @result = [nb_order_insert] @o_buyerid,o_id output
3.SELECT 数据集返回值
复制代码代码如下:
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
（1）、使用临时表的方法
复制代码代码如下:
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
1.获取Return返回值
复制代码代码如下:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnStr"].ToString());
conn.Open();
SqlCommand MyCommand = new SqlCommand("nb_order",conn);? //存储过程名字
MyCommand.CommandType = CommandType.StoredProcedure; //指定类型为存储过程
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();??????????????? //执行存储过程
Response.Write(MyCommand.Parameters["@return"].Value.ToString()); //取得return的返回值
2.获取Output输出参数值
复制代码代码如下:
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()); //指定取得存储过程的返回值
C#接收存储过程返回值:
复制代码代码如下:
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;?? //指定存储过程? AddWithValue可以指定名称和值，而Add需要指定名称，类型，再给value
???????? 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;?? //指定输出参数是返回值????
???????? try
???????? {
???????????? conn.Open();
???????????? cmd.ExecuteNonQuery(); //执行存储过程
???????????? iRet = (int)cmd.Parameters["@RETURN_VALUE"].Value;??? //取得return的值
???????? }
???????? catch (SqlException ex)
???????? {
???????????? throw ex;
???????? }
???????? finally
???????? {
???????????? conn.Close();
???????? }
???????? return iRet;
???? }
C#接收存储过程的输出参数:
复制代码代码如下:
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;? //利用Add方法为其添加名称，类型和输出参数
??????? try
??????? {
??????????? conn.Open();
??????????? cmd.ExecuteNonQuery();
??????????? iRet = (decimal)cmd.Parameters["@Amount"].Value;? //取得存储过程中的输出参数
??????? }
??????? catch (SqlException ex)
??????? {
??????????? throw ex;
??????? }
??????? finally
??????? {
??????????? conn.Close();
??????? }
??????? return iRet;
??? }
C#取得结果集：
复制代码代码如下:
string sqlw = string.Format("exec sp_UserInfo {0}",uid);
??????????? DataTable dsuser = SqlConn.GetDataSet(sqlw).Tables[0];
?public static DataSet GetDataSet(string sql) ??????? { ??????????? string connStr = System.Configuration.ConfigurationManager.ConnectionStrings["ConnStr"].ToString(); ??????????? SqlConnection conn = new SqlConnection(connStr); ??????????? SqlCommand cmd = new SqlCommand(sql,conn); ??????????? SqlDataAdapter da = new SqlDataAdapter(cmd);? //直接用SqlDataAdapter将结果集取出来放入dataset中 ??????????? DataSet ds = new DataSet(); ??????????? da.Fill(ds); ??????????? conn.Close(); ??????????? cmd.Dispose(); ??????????? return ds; ??????? }
