Note A CASE expression with no ELSE clause has an implicit ELSE NULL. For each target column, the CASE expression will return the value (val column) only if the source row had the corresponding order year; otherwise, the CASE expression will return NULL. PIVOT s third phase (P3) applies the speci ed aggregate function on top of each CASE expression, generating the result columns. In our case, the expressions logically become the following:

UNPIVOT
UNPIVOT is the inverse of PIVOT, rotating data from columns to rows. Before I demonstrate UNPIVOT s logical phases, rst run the following code, which creates and populates the dbo.EmpYearValues table and queries it to present its content:
SELECT * INTO dbo.EmpYearValues FROM (SELECT empid, YEAR(orderdate) AS orderyear, val FROM Sales.OrderValues) AS OV PIVOT(SUM(val) FOR orderyear IN([2006],[2007],[2008])) AS P;
1
UPDATE dbo.EmpYearValues SET [2006] = NULL WHERE empid IN(1, 2); SELECT * FROM dbo.EmpYearValues;
Logical Query Processing
This code returns the following output:
empid ----------3 6 9 7 1 4 2 5 8 2006 ---------18223.96 16642.61 9894.52 15232.16 NULL 49945.12 NULL 18383.92 22240.12 2007 ---------108026.17 43126.38 26310.39 60471.19 93148.11 128809.81 70444.14 30716.48 56032.63 2008 ---------76562.75 14144.16 41103.17 48864.89 63195.02 54135.94 74336.56 19691.90 48589.54
I ll use the following query as an example to describe the logical processing phases involved with the UNPIVOT operator:
SELECT empid, orderyear, val FROM dbo.EmpYearValues UNPIVOT(val FOR orderyear IN([2006],[2007],[2008])) AS U;
This query unpivots (or splits) the employee yearly values from each source row to a separate row per order year, generating the following output:
empid ----------3 3 3 6 6 6 9 9 9 7 7 7 1 1 4 4 4 2 2 5 5 5 8 8 8 orderyear ---------2006 2007 2008 2006 2007 2008 2006 2007 2008 2006 2007 2008 2007 2008 2006 2007 2008 2007 2008 2006 2007 2008 2006 2007 2008 val ----------18223.96 108026.17 76562.75 16642.61 43126.38 14144.16 9894.52 26310.39 41103.17 15232.16 60471.19 48864.89 93148.11 63195.02 49945.12 128809.81 54135.94 70444.14 74336.56 18383.92 30716.48 19691.90 22240.12 56032.63 48589.54
Inside Microsoft SQL Server 2008: T-SQL Querying
The following three logical processing phases are involved in an UNPIVOT operation: 1. U1: Generating Copies 2. U2: Extracting Elements 3. U3: Removing Rows with NULLs The rst step (U1) generates copies of the rows from the left table expression provided to UNPIVOT as an input (EmpYearValues, in our case). This step generates a copy for each column that is unpivoted (appears in the IN clause of the UNPIVOT operator). Because there are three column names in the IN clause, three copies are produced from each source row. The resulting virtual table will contain a new column holding the source column names as character strings. The name of this column will be the one speci ed right before the IN clause (orderyear, in our case). The virtual table returned from the rst step in our example is shown in Table 1-10.
TABLE 1-10
