  How would you create a query to get the Metric as columns? Basically, to look like this.

  YearMonth BariatricSurgery BISurgeries EDTransfersToBI

  2014-10 100 10 50

  2014-11 50 30 20

  create table TEST

  (

  YearMonth varchar(7),

  Metric varchar(25),

  Data int

  )

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','BariatricSurgery',0)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','BISurgeries',113)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','EDTransfersToBI',40)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','GYNOncProcedures',0)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','GYNOncVisits',0)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','InpatientTransfersToBI',18)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','OPVisitsByBI',18)

  insert into TEST(YearMonth, Metric, Data) values( '2013-07','PercentAdmitsFromED',70)

  You need a dynamic PIVOT.

  Looks like this does the trick:

  DECLARE @sql nvarchar(max)

  SELECT @sql = STUFF((

  SELECT DISTINCT ',' + QUOTENAME(Metric)

  FROM TEST

  FOR XML PATH(''), TYPE).value('.','nvarchar(max)'),1,1,SPACE(0))

  SET @sql = '

  SELECT *

  FROM TEST

  PIVOT (SUM(Data) FOR Metric IN ('+ @sql +')) AS pvt'

  EXEC(@sql)

  A common or garden pivot will do the same too. As a genuine question on my part, why would a dynamic pivot be the first choice here?

  Not sure it's the first choice, but I assumed the list of columns to pivot was longer in the actual data.

  Yes, you're right: if the column list is known upfront, there's no need to use dynamic pivot.

  Fair enough, I was just wondering if'd missed something 🙂 I think that QUOTENAME is going to be something that will make my life easier though.
