Can anyone confirm for me that SelectionId is a unique field?

[JohnFromCairnsAustralia]

Hello there,

Just wondering if anyone could confirm for me that the selection Id is a unique field that can be used to identify a runner between markets, or its specific to a market?

For example. Lets say. Mr Brown horse is running on tuesday, wednesday, and thursday of this week in three different racing markets (he loves to race).

Will the RunnerDescription for Mr Brown horse have the same SelectionId for all three races or a different one?

Thank you kindly for any thoughts
John

"The selectionId is unique to each runner and not to each market." so Mr Brown horse will have the same Selection Id for each race.

Hope this thread ends up being useful to someone rather than being pollution.

Correct you need to use MarketID and SelectionID as the same runner has the same SelectionID in both win and place markets. BUT that whys you have a different MarketID

Thank you for the confirmation. Very helpful.

Note also that the SelectionId is same between all markets really...

I focus on horses. In my mind I have started thinking of RunnerDescription as a Horse entity. And the Runner as dynamic information about that horse for a particular market.

In a generic app one would probably have the RunnerDescription as a base class entity, the subclasses like Horse or FootballTeam as subclasses...
