Question

How to correct added records to the table with correct order number on SQL Server 2000?

I have the following ordered table:

OrderNo Data
      0    A
      1    B
      2    C

I need to add the following records to the table (with order saving):

OrderNo Data
      2    E
      3    F
      1    D

And to get the following as the result on the table:

OrderNo Data
      0    A
      1    B
      2    C
      3    D
      4    E
      5    F

How to do this on SQL Server 2000?

P.S. OrderNo can’t be identity or unique.

        from Table1 as e2
        where e2.OrderNo <= e1.OrderNo) as OrderNo, e1.Data
from Table1 as e1
ORDER BY OrderNo
