Microsoft SQL Server PIVOT / UNPIVOT
Syntax
- SELECT
<non-pivoted column>,
[first pivoted column] AS<column name>,
[second pivoted column] AS<column name>,
...
[last pivoted column] AS<column name>
FROM
(<SELECT query that produces the data>)
AS<alias for the source query>
PIVOT
(
<aggregation function>(<column being aggregated>)
FOR
[<column that contains the values that will become column headers>]
IN ( [first pivoted column], [second pivoted column],
... [last pivoted column])
) AS<alias for the pivot table><optional ORDER BY clause>;
Remarks
Using PIVOT and UNPIVOT operators you transform a table by shifting the rows (column values) of a table to columns and vise-versa. As part of this transformation aggregation functions can be applied on the table values.
