  • RE: Record Selection

    Hard to determine exactly what you want, but my best guess is something like below; adjust the case conditions to be specifically what you need them to be:

  • RE: Log Table - Determining Old Value vs New Value

    As I have 2 log tables to pull data from, how would this work?

    do you mean by just having a clustered index by the modified date on both log...

  • RE: Log Table - Determining Old Value vs New Value

    Properly clustering should still allow a merge join, which should be much faster than anything you're having to do now.

  • RE: Log Table - Determining Old Value vs New Value

    Cluster the log table on the relevant arrival datetime that you are comparing by (rather than, presumably, a meaningless identity value). Then query directly from the table, joining to...

    This mistake is most commonly made by old COBOL programmers, because COBOL represents everything in character strings.

    No, actually COBOL had numeric values as well. For example, packed decimal...

  • RE: Code first vs rightsizing nvarchar(n)/nvarcar(max)

    You're right. Nvarchar shouldn't be used unless it's needed or realistically could be needed.
