Hello,
I'm extracting data from a Oracle table to create a new table with codes such as:
Table name: Routers
Desc
Router Hall
Router Room156
Router Shelter
...
I want to add a unique key to identify the separate routers.
(I have tried COUNTER, CRCCalculator, attributecreater etc). Is there a simple way to create unique number these routers?

You can use the SQLCreator instead of an Oracle reader and have the database create the unique number using a SQL statement like:
Select rownum, desc, router hall etc from Routers;
The rownum will give you a sequence number per records.

I am wondering. What part was not simple when using the Counter?

Hi all, thanks for your input.
I'm extracting data from sqlserver.
Sqlcreator ic ROWNUM will give an error
'Provider error `(-2147217900) Invalid column name 'ROWNUM'.
I'm trying to make a table as follows:
TYPE ID(number) DESC
RESULT 0 FORCED NOT READY
RESULT 1 ABANDONED
RESULT 2 ANSWERED
RESULT 9 ONBEKEND
EVENT 0 CallEnd
EVENT 1 FNR
EVENT 2 Incoming
.....
I use several SQLCREATORS to extract data from sqlserver.
Type: a new attribute I create
ID: a unique number per TYPE
DESC: the data I extract from several dbo,[] from the sqlserver.
CRCCalculator will not give me an ID as specified and I did not succeed with Counter.
Perhaps there is a better way to do this?

I do not know the SQL Server equivalent.

does row_number() over() work?
That should give you a unique value for every row.

YES !!!
I made the following query on SQL server and this works good:
SELECT 'EVENT' as TYPE,
ROW_NUMBER() OVER (ORDER BY [EventType] ASC) AS ID,
[EventType] AS DISCRIPTION
from
dbo.[RawHistData_RouterAgentDataView]
group by [EventType]
order by 1
Thank you all for the great help.
