Question

I am attempting to create a view in SQL Server 2000 that splits data into individual records from a source table. Source table looks like this:

ShipID, AirlineID, Airport1, Airport2, AirlineID2, Airport3, Airport4, AirlineID3, Airport5, Airport6

My view needs to look like this:

ShipID, Airline, Origin, Destination

So my view needs to split each source record into up to three records in the view

Anyone know how best to do this?

Answer 1

This should set you to your way. Mind added column Transfer. It is here to allow you to sort your flights by timeline.

select ShipID, 1 Transfer, AirlineID, Airport1 Origin, Airport2 Destination
  from mySourceTable
 where Airport1 is not null
union all
select ShipID, 2, AirlineID2, Airport3, Airport4 
  from mySourceTable
 where Airport3 is not null
union all
select ShipID, 3, AirlineID3, Airport5, Airport6 
  from mySourceTable
 where Airport5 is not null
order by 1, 2
