Pivoting Example 1: Pivot Keys - Teradata Vantage

This example specifies the PivotColumn argument and, with the PivotKeys argument, the values from the pivot column to use as pivot keys. Because PivotKeys does not include 'dewpoint', the function ignores rows that include 'dewpoint'.

Input

The input table, pivot_input, contains temperature, pressure, and dewpoint data for three cities, in sparse format.

SQL Call

SELECT * FROM Pivoting (
  ON pivot_input PARTITION BY sn, city, week ORDER BY week, attribute
  USING
  PartitionColumns ('sn', 'city', 'week')
  PivotKeys ('temp', 'pressure') 
  PivotColumn ('attribute') 
  TargetColumns ('value1')
) AS dt ORDER BY 1,2,3;

Output

The function outputs the input column contents in dense format in the output columns value_temp and value_pressure, which contain the temperature and pressure, respectively. Because these values are numeric, the function casts them to VARCHAR.
