  • Auto generate varchar Ticket number via DB...

    - by Rusty
    Hello, I'm looking for suggestion on how to get the DB to auto generate Ticket numbers (preferably via the SQL DB) for a varchar column. I have the following tables in the DB: Activities & Cases and would prefer the format to be "Act000001" or "Cse000001". This would be something similar to the identity column property. Any suggestion would be highly appreciated. Thanks. Rusty

  • In a star schema, are foreign key constraints between facts and dimensions neccessary?

    - by Garett
    I'm getting my first exposure to data warehousing, and I’m wondering is it necessary to have foreign key constraints between facts and dimensions. Are there any major downsides for not having them? I’m currently working with a relational star schema. In traditional applications I’m used to having them, but I started to wonder if they were needed in this case. I’m currently working in a SQL Server 2005 environment.
