Question

我正在尝试在存储过程中使用OUTPUT语句，以便返回新插入行的ID。存储过程是：

CREATE PROCEDURE PROC_RESTORE_REQUEST_TO_QUEUE
    @cs_uri_stem varchar(900),
    @cs_uri_query varchar(2500),
    @date datetime,
    @time datetime,
    @queue_state smallint,
    @process_id int,
    @simulation_start_time bigint,
    @num_failures smallint

AS

SET NOCOUNT ON

INSERT INTO [DD#WORK].[dbo].[ebhFifoQueue] ([cs-uri-stem],[cs-uri-query],[date],[time],[queue_state],[process_id],[simulation_start_time],[num_failures]) 
VALUES (@cs_uri_stem,@cs_uri_query,@date,@time,@queue_state,@process_id,@simulation_start_time,@num_failures) 

OUTPUT INSERTED.id

当我尝试编译此存储过程时，收到错误消息：

'OUTPUT'附近的语法不正确。

我尝试了几种这种代码的排列无效（相同的错误消息），包括将OUTPUT语句移动到与INSERT语句相同的行。你知道我的语法有什么问题吗？在此先感谢您的帮助，

Answer 1

它的顺序。 The OUTPUT clause应该在INSERT和VALUES行之间。

移动你的，就像这样：

INSERT INTO [DD#WORK].[dbo].[ebhFifoQueue] ([cs-uri-stem],[cs-uri-query],[date],[time],[queue_state],[process_id],[simulation_start_time],[num_failures]) 
OUTPUT INSERTED.id
VALUES (@cs_uri_stem,@cs_uri_query,@date,@time,@queue_state,@process_id,@simulation_start_time,@num_failures)

Answer 2

我认为应该是这样的：

INSERT INTO [DD#WORK].[dbo].[ebhFifoQueue] ([cs-uri-stem],[cs-uri-query],[date],[time],[queue_state],[process_id],[simulation_start_time],[num_failures])

OUTPUT INSERTED.id 

VALUES 
(@cs_uri_stem,@cs_uri_query,@date,@time,@queue_state,@process_id,@simulation_start_time,@num_failures)

您还可以在OUPUT语句后添加“INTO @MyVariable”或“INTO MyTable”

Answer 3

来自MSDN

DECLARE @MyTableVar table( NewScrapReasonID smallint,
                           Name varchar(50),
                           ModifiedDate datetime);

INSERT Production.ScrapReason
    OUTPUT INSERTED.ScrapReasonID, INSERTED.Name, INSERTED.ModifiedDate
        INTO @MyTableVar
VALUES (N'Operator error', GETDATE());

Answer 4

应该是这样的：

CREATE PROCEDURE PROC_RESTORE_REQUEST_TO_QUEUE 
    @cs_uri_stem varchar(900), 
    @cs_uri_query varchar(2500), 
    @date datetime, 
    @time datetime, 
    @queue_state smallint, 
    @process_id int, 
    @simulation_start_time bigint, 
    @num_failures smallint,
    @new_id int OUTPUT

AS 

SET NOCOUNT ON 

INSERT INTO [DD#WORK].[dbo].[ebhFifoQueue] ([cs-uri-stem],[cs-uri-query],[date],[time],[queue_state],[process_id],[simulation_start_time],[num_failures])  
VALUES (@cs_uri_stem,@cs_uri_query,@date,@time,@queue_state,@process_id,@simulation_start_time,@num_failures)  

SET @new_id = SCOPE_IDENTITY()

这个OUTPUT语句（SQL Server 2005）的语法有什么问题？
