BIT_XOR_AGG

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

An aggregate function to perform the equivalent of the BIT_XOR function on a data set. In other words, the resulting bits are:

  • 1 at position p if the argument is 1 at position p for an odd number of rows in the group.
  • 0 at position p if the argument is 0 at position p for an even number of rows in the group.

As with most aggregate functions, NULL values are not aggregated. 

SELECT
  bit_xor_agg(ID),
  bit_xor_agg(AUTHOR_ID)
FROM BOOK
create.select(
         bitXorAgg(BOOK.ID),
         bitXorAgg(BOOK.AUTHOR_ID))
      .from(BOOK)

Producing: 

+-------------+-------------+
| bit_xor_agg | bit_xor_agg |
+-------------+-------------+
|           4 |           0 |
+-------------+-------------+

Dialect support

This example using jOOQ:

bitXorAgg(BOOK.ID.coerce(TINYINT))

Translates to the following dialect specific expressions:
