The value of VAL will be same for Same Units ?

[no name] 5-Sep-14 3:28am

no

Why don't you add an auto-increment field as ID?

[no name] 5-Sep-14 3:41am

I don't have that ID and don't have rights to edit a table

Solution 1

You can create a View

SQL

CREATE VIEW view1
AS
 SELECT Row_Number() AS ID, Units, Val
 FROM Table1

Hi,

As far as i know, SQL Server does not maintain ROWID concept as of Oracle.

You can try these steps...

1. Create a new table with one identity column.
2. Dump all the data from original table to new table.
3. Since you have unique id in new table, now you can update the details as required.
4. Drop the original table.
5. Rename the new table with original name.

All above steps can be shortened if you introduce identity column in your table.

Hope this will help you.

Cheers
