Hi guys,

Is it possible to have in an INSERT statement, an extra field which is something like this:

'Material:'+@UID_OF_THIS_RECORD

So basically, mixing text, with the INT, UID of the record being Inserted, or would I need to do it in an UPDATE after the INSERT? If so, how would I know what the UID of the Inserted record is?

Cheers guys!

you need to update the fields after insert.
when you insert the records then you can get the unique value which is inserted.

and then you can update this value in the record which is inserted.

OK, and what code is used to get the unique value of the Inserted Record?

will the value ever change once the record is created?
-> if no, make this a computed field and not a "true" field.

-> yes
  is it identity or uniqueidentified?

The value will never change, it is done once, and that is it. :)

Would something like this work?


INSERT INTO dbo.tblModule
(
      DeviceID,
      ModuleCatID,
      SlotID,
      [Serial Number],
      Module_FL,
      SAP_EQ
) VALUES (
      @DeviceUID,
      @ModuleCatUID,
      @SlotUID,
      @serial,
      @data,
      @equipment
)
UPDATE dbo.tblModule
SET NodeName = 'Module:'+@@IDENTITY
WHERE UID = @@IDENTITY

Change your Update to:
UPDATE dbo.tblModule
SET NodeName = 'Module:'+CAST(SCOPE_IDENTITY() AS VARCHAR(10))
WHERE UID = SCOPE_IDENTITY()

If you are expecting bigint as the ID, cast as VARCHAR(19).
AngelIII's method is much more integrated. Unsure about speed for a computed field though.
