  • RE: Duplicate Names, but Not Duplicate IDs

    I like the technique overall, but the concatenation will likely hurt performance: maybe only slightly, maybe a lot, depending on indexing. Thus, I suggest GROUPing and JOINing w/o any...

  • RE: Data file unused space issue

    For a 500GB db, those are modest amounts of space to be available/reserved.

  • RE: Trying to get table size without sysobjects and sysindexes

    FYI, in case you want it, here's the query I use to get an overview of tables, indexes and their sizes:

    Thanks, that's what I initially had on my system. It is apparent now, that there is no way
