I’m working in Visual Studio – VB.NET.

My problem is that I want to delete a specific row in SQL Server but the only unique column I have is an Identity that increments automatically.

My process of work:
1. I add a row in the column (the identity is being incremented, but I don’t know the number)
2. I want to delete the previous row

Is there a sort of unique ID that every new record has?
It’s possible that my table has 2 exactly the same records, just the sequence (identity) is different.

Any ideas how to handle this problem?

    SQL Server has a few functions that return the generated ID for the last rows, each with it’s own specific strengths and weaknesses.

    Basically:

    • @@IDENTITY works if you do not use triggers
    • SCOPE_IDENTITY() works for the code you explicitly called.
    • IDENT_CURRENT(‘tablename’) works for a specific table, across all scopes.

    In almost all scenarios SCOPE_IDENTITY() is what you need, and it’s a good habit to use it, opposed to the other options.
    A good discussion on the pros and cons of the approaches is also available here.
