Transcript of "Brent Ozar Twitter Chat - What Developers Need to Know about SQL Server"

  1. 1. What Developers Need to Know About SQL Server Brent Ozar
  2. 2. What Features, Commands, Datatypes, Etc. Should Be Generally Avoided? If you say BETWEEN December 1st and December 31st, SQL Server sees that last parameter as the very beginning of December 31st. Any data from, say, 1AM on December 31st and afterwards is going to be excluded. Simplicity is a big theme here. Manhandling the engine around with hints usually results in worse performance overall. 2 Confidential Global Marketing
  3. 3. We’re not saying nested views are wrong – sometimes they can work really well – but KBK is pointing out that you may end up dragging a bunch more tables into your query inadvertently. Always good advice – but it’s advice for managers rather than developers, right? Sometimes, a scan is easier – especially for grouping. 3 Confidential Global Marketing
