PIVOT - Kinetica Docs

The PIVOT clause can be used to pivot columns, “rotating” column values into multiple columns (one for each value), creating wider and shorter denormalized tables from longer, more normalized tables.

PIVOT Syntax

<select statement>
PIVOT
(
    <aggregate expression [AS <alias>]>[,...]
    FOR <column> IN (<column list>)
)

For example, given a source table phone_number, which lists each phone number for a customer as a separate record in the table, a pivot operation can be performed, creating a single record per customer with the home, work, & cell phone numbers as separate columns. With this data:

Input

+--------+--------------+----------------+
| name   | phone_type   | phone_number   |
+--------+--------------+----------------+
| Jane   | Home         | 123-456-7890   |
| Jane   | Work         | 111-222-3333   |
| John   | Home         | 123-456-7890   |
| John   | Cell         | 333-222-1111   |
+--------+--------------+----------------+

The following pivot operation can be applied:

PIVOT Example

SELECT
    name,
    Home_Phone,
    Work_Phone,
    Cell_Phone
FROM
    example.phone_list
PIVOT
(
    MAX(phone_number) AS Phone
    FOR phone_type IN ('Home', 'Work', 'Cell')
)

The data will be pivoted into a table like this:

Output

+--------+----------------+----------------+----------------+
| name   | Home_Phone     | Work_Phone     | Cell_Phone     |
+--------+----------------+----------------+----------------+
| Jane   | 123-456-7890   | 111-222-3333   |                |
| John   | 123-456-7890   |                | 333-222-1111   |
+--------+----------------+----------------+----------------+
