  • RE: Can't drop index due to FK enforcement

    AZ Pete (4/2/2014)


    Thanks folks for the replies. However, my question is *why* did SQL Server elect to use the unique index defined on the TransmissionId column versus using the Primary...

    To allow the best possible use of any existing indexes, approach 1 is vastly superior to 2. Neither is best, however. Instead, assuming "endDate" is a date/datetime/etc., use...

  • RE: Unable to shrink large database (data file)

    I think this will depend most on your I/O subsystem's speed.

  • RE: SQL beginner - books and material

    For DBA, be aware that having no experience will make this a very difficult transition. Most employers don't hire completely inexperienced DBAs.

    For DBA, download SQL Express, 2008 or 2012.

    I've found the creation of a script and then restoring from a production backup to be very reliable.

    I think you can simplify the query something like below, although some tweaking might need done:

    derived.NumOfDupPermits, derived.AmendedDups, derived.DistinctPermits

    FROM (
