sp_Query_Pivot.sql

By DatabaseJournal.com Staff



This script generates simple pivot tables on data and outputs the final SQL statement via Print.

For example, given data as shown below:

ID          year        type        amt
----------- ----------- ----------- -----------
7           1999        1           23
8           1999        2           44
9           1999        3           55
10          2000        1           66
11          2000        2           77
12          2000        3           88
13          1999        1           11

... you can pivot the data to show the years down the side and the types across the top...

year        1           2           3           RowTotal
----------- ----------- ----------- ----------- -----------
1999        34          44          55          133
2000        66          77          88          231

... and get the SQL which would produce this table

     SELECT Pivot_Data.*,
      (Pivot_Data.[1] + Pivot_Data.[2] + Pivot_Data.[3]) AS RowTotal
     FROM (SELECT [year],
     SUM(CASE [type] WHEN '1' THEN [amt] ELSE 0 END) AS [1],
     SUM(CASE [type] WHEN '2' THEN [amt] ELSE 0 END) AS [2],
     SUM(CASE [type] WHEN '3' THEN [amt] ELSE 0 END) AS [3]
      FROM (select * from zzjunk) AS Base_Data
     GROUP BY [year]) AS Pivot_Data

.. by calling the procedure as shown below:

exec sp_Query_Pivot 'select * from zzjunk', '[year]', '[type]',
     'Select distinct [type] from zzjunk', 'SUM', '[amt]', 'Y'
