共享来自SQL存储过程的自动增量值

Question

I have a stored procedure that inserts data on a table with an auto-increment id (name of 'requestid'). As I insert data into it using the procedure, I want to take the value of the auto-increment field and use it on another query to the same stored procedure. How do I do that? Thank you in advance for your time.

CREATE PROCEDURE [dbo].[sp_Create_new_request]
       @employeeid                     INT                    , 
       @requestdate                    DATETIME               , 
       @deliverdate                    DATETIME               , 
       @totalcost                      MONEY                 

AS 
BEGIN 


     INSERT INTO dbo.Requests
          ( 
            EmployeeID                    ,
            RequestDate                   ,
            DeliverDate                   ,
            TotalCost                     

          ) 
     VALUES 
          ( 
            @employeeid                   ,
            @requestdate                  ,
            @deliverdate                  ,
            @totalcost                    

          ) 



END 

Answer 1

Try

CREATE PROCEDURE [dbo].[sp_Create_new_request]
   @employeeid                     INT                    , 
   @requestdate                    DATETIME               , 
   @deliverdate                    DATETIME               , 
   @totalcost                      MONEY,
requestid               INT             = NULL OUT                 

AS 
BEGIN 


 INSERT INTO dbo.Requests
      ( 
        EmployeeID                    ,
        RequestDate                   ,
        DeliverDate                   ,
        TotalCost                     

      ) 
 VALUES 
      ( 
        @employeeid                   ,
        @requestdate                  ,
        @deliverdate                  ,
        @totalcost                    

      ) 

 SET @requestid = SCOPE_IDENTITY();

END

您不应使用自动增量，而应使用序列来增量，然后可以在任何地方重用该值。

You can use also :

IDENT_CURRENT ('dbo.Requests')
