Question

I am trying to find the best way to display some data.

My dataset looks like this:

Form  var1_Day  var1_WTD  var1_30Day  var2_Day  var2_WTD  var2_30Day ...
NA    null      null      null        77        448       2581
A1    166       791       4842        null      null      null
A2    304       1312      8365        null      null      null
A3    29        113       656         null      null      null

I am trying to figure out how I would go about displaying the data like this:

Var   Form  Day   WTD   30Day
var1  NA    null  null  null
var1  A1    166   791   4842
var1  A2    304   1312  8365
var1  A3    29    113   656
var2  NA    77    448   2581
var2  A1    null  null  null
var2  A2    null  null  null
var2  A3    null  null  null
...

I believe I will have to use a pivot table but am not sure where to start.

Thank You,

Actually, you want UNPIVOT

Like so…

select SUBSTRING(t,1,4) as Var, form, day, wtd, 30day 
from yourtable
unpivot ([day] for d in (var1_day,var2_day)) td
unpivot ([wtd] for w in (var1_wtd,var2_wtd)) tw
unpivot ([30day] for t in (var1_30day,var2_30day)) tt
where SUBSTRING(d,1,4) = SUBSTRING(w,1,4)
and  SUBSTRING(d,1,4) = SUBSTRING(t,1,4)
