return a value from an INSERT statement

I am trying to return the value of the item that was just inserted using a stored procedure.  I have 2 stored procedures, GET_ID, and NEW_ID.  When I call NEW_ID, I want it to create a new ID in the table (based on a formula) and return the value of the new id.  I cannot use identity as the value is not autogenerated, it is calculated. EX:

Create Procedure test
(
    @in varchar(50)
)
As
    declare @NewID varchar(50)
    set @NewID = CONVERT(varchar(50), NEWID())
   
    insert into table1 (newid)
    values (@NewID)

-- All I want is the value of @NewID returned after this executes.  Any help would be great.

Here is an example

CREATE PROCEDURE titles_sum @@TITLE varchar(40) = '%', @@SUM money OUTPUT
AS
SELECT 'Title Name' = title
FROM titles
WHERE title LIKE @@TITLE
SELECT @@SUM = SUM(price)
FROM titles
WHERE title LIKE @@TITLE
GO

While using execute you will have to declare this parameter (@@SUM) as output.

Create Procedure test
(
    @in varchar(50)
)
As
Set NoCount On
    declare @NewID varchar(50)
    set @NewID = CONVERT(varchar(50), NEWID())
     
    insert into table1 (newid)
    values (@NewID)

    Select  NewID
    From    table1
    Where   NewID = @NewID

This shoud see your pocedure return a recordset with one column, NewID, and it's value, the same value you have just put in to it. I noticed that you have a variable @in varchar(50) passed in to the stored procedure, but your code doesn't seem to use it, I assume you meant to use it with your Convert(varchar(50),NewID()) bit?

Sorry the last statement is required only if it is a local variable.

DawsonB... that was the first thing I tried.  When I execute the procedure, it does not return any records.  It completely ignores the SELECT statement.

I even tried creating a simpe select procedure GETID and adding

EXEC sp_GETID @input

with the same results.  When I execute the GETID procedure, it works fine and returns records.  when I do the NEWID it does not return any records.

Is this Microsoft SQL Server?

If so what version?

If it is Version 7 did you note the "Set NoCount On" in the example from DawsonB?

It is MSDE. Which is shrunken SQL 7

When I put in SET NOCOUNT ON, it returns empty recordsets. Without it, it returns no data.

Not having used that particular product... Does it have the equivalent of Query analyser or can you execute sql in an interactive environment?

If so note the output:

In SQL Server 7 it is possible (when using certain odbc drivers) to have two values returned as record sets. The first is the values expected the second is the output "n rows affected".

If you don't set nocount on then your subsequent operations will be using the last record set returned and everything gets confused.

Happened to me several times before I found out.

Actually, you can use Access 2000 to interface with MSDE and do all your work from there.  Since I am only trying to retrieve one value, can I just return the NEW_ID value that is generated instead of a recordset with a single piece of data in it?

Ok, this is actually more efficient, but is this bit:
    set @NewID = CONVERT(varchar(50), NEWID())
 supposed to look something like
    set @NewID = CONVERT(varchar(50), @in())
???

As far as I can tell, the sp as it is written wont do anything with @in.
Your Convert is on NewID?




Create Procedure test
(
    @in varchar(50)
)
As
Set NoCount On
    declare @NewID varchar(50)
    set @NewID = CONVERT(varchar(50), @in())
     
    insert into table1 (newid)
    values (@NewID)

    Select  @NewID as NewID

Try that,

DawsonBCommented:
Sorry, I didn't explain

Select @NewID as NewID will return a recordset of one field named NewID, with the value of the Variable @NewID, and as there is no reading of a table, it is both more efficient, and more correct in this case.
The problem I think though is as I mentioned in my previous message regarding the convert of @in & newid.
