sqlserver获取存储过程返回值 1.OUPUT参数返回值
[sql] view plaincopyprint?
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??
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
2.RETURN过程返回值
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?=?@@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
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
