  #268816

  Hello Everyone

  I have a rather odd query that I am trying to figure out the best way to code. I am going to try and explain the best way possible. I want to be able to do this without incorporating a loop.

  I have a table that stores patient information about Diagnosis. There are three distinct hospital locations. Lets Call them LA, NY and Indy. There are three CodeNumbers for each Location : 30.1, 40.1 and 50.1

  Now, what I am after is the count for each CodeNumber, per Each Location per each day.

  These are the counts of each code per each location per each day.

  Counts:

  LA = 402 = Total

  LA - 30.1 = 57

  LA - 40.1 = 278

  LA - 50.1 = 67

  NY = 82 = Total

  NY - 30.1 = 13

  NY - 40.1 = 55

  NY - 50.1 = 14

  Indy = 142 = Total

  Indy - 30,1 = 19

  Indy - 40.1 = 77

  Indy - 50.1 = 46

  The way the data is stored is like this:

  --===== If the test table already exists, drop it

  IF OBJECT_ID('TempDB..#Diagnosis','U') IS NOT NULL

  DROP TABLE #Diagnosis

  --===== Create the test table with

  CREATE TABLE #Diagnosis

  (

  RowID INT IDENTITY(1,1) PRIMARY KEY CLUSTERED

  , DateDataRepresents Date

  , CodeNumber DECIMAL(4,1)

  , Location varchar(5)

  )

  INSERT INTO #Diagnosis

  (DateDataRepresents, CodeNumber, Location)

  SELECT '2012-12-16', 30.1, 'NY' UNION ALL

  SELECT '2012-12-16', 40.1, 'LA' UNION ALL

  SELECT '2012-12-16', 40.1, 'LA' UNION ALL

  SELECT '2012-12-16', 40.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 50.1, 'NY' UNION ALL

  SELECT '2012-12-16', 40.1, 'NY' UNION ALL

  SELECT '2012-12-16', 30.1, 'NY' UNION ALL

  SELECT '2012-12-16', 50.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 50.1, 'NY' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 30.1, 'NY' UNION ALL

  SELECT '2012-12-16', 50.1, 'LA' UNION ALL

  SELECT '2012-12-16', 50.1, 'LA' UNION ALL

  SELECT '2012-12-16', 50.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 40.1, 'LA' UNION ALL

  SELECT '2012-12-16', 40.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'NY' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 50.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'LA' UNION ALL

  SELECT '2012-12-16', 50.1, 'NY' UNION ALL

  SELECT '2012-12-16', 30.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 50.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 40.1, 'NY' UNION ALL

  SELECT '2012-12-16', 40.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 50.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'NY' UNION ALL

  SELECT '2012-12-16', 50.1, 'LA' UNION ALL

  SELECT '2012-12-16', 30.1, 'Indy' UNION ALL

  SELECT '2012-12-16', 50.1, 'NY'

  SELECT

  DateDataRepresents

  , CodeNumber

  , Location

  FROM #Diagnosis;

  DROP TABLE #Diagnosis;

  etc.........

  The table has approx half a million rows

  What is the most efficient way to get the counts?

  Thank You in advance for your help, suggestions and advice

  Thanks is perfect.

  Thank You. I greatly appreciate that. I never thought to use cube.

  If also not familiar lookup WITH ROLLUP, its another one to look at along with WITH CUBE, both produce different outputs so need to ensure you choose the right one, ROLLUP wont work in this instance but CUBE does.

  Also, since this is SQL 2008, have a read up on Grouping Sets. They allow a lot more flexibility than cube and rollup do.

  Especially since WITH CUBE and WITH ROLLUP are being deprecated.

  Thank You Everyone

  Ok, I have been reading up on Grouping Sets, but I still am not getting it. How would one go about writing a query to work correctly with the same data that was given and not use Cube or Rollup?

  Thanks in advance

  You could always "roll your own" Totals. Performs fine with the small sample data set; if your production set is much larger, you'd want to compare metrics to see if this code scales.
