Inline Non-Clustered Indexes

If you’re using SQL Server 2014, you get the benefit of writing inline non-clustered indexes.  Denny Cherry has more:

As for the syntax it’s pretty straight forward. Below is a sample table with a couple of indexes, one created on the column c2 and one created on C1 and C2. Now sadly include columns aren’t supported with inline indexes, but hopefully that’ll show up in a future version of SQL Server.

This was added for In-Memory OLTP support, and I like it.  For more on Denny’s comment about tempdb performance, check out a slide deck Eddie Wuerch used to teach people (including me) about temp table reuse.
