Question

I’m having trouble getting in touch with SQL Server Managemen Studio 2008! I want to create a link-table that will link an Event to many Audiences (EventAudience).

An example of the data that could be contained:

EventId | AudienceId

  4              1   5              1   4              2 

However, I don’t want this:

EventId | AudienceId

  4              1   4              1 

I’ve been looking at relationships and constraints.. but no joy so far!

As a sneaky second part to the question, I would like to set up the Audience table such that if a row is deleted from Audience, it will clear down the EventAudience link table in a cascading manner.

As always, ANY help/advice appreciated!

Thanks Pete

Answer 1

Just use:

CREATE UNIQUE INDEX UQ_EventAudience ON dbo.EventAudience(EventID, AudienceID);
