BOOL_OR

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

The BOOL_OR() aggregate function calculates the boolean disjunction of all the boolean values in the aggregated group. In other words, this is:

  • FALSE if the argument is FALSE for every row in the group.
  • TRUE if at the argument is TRUE for at least one row in the group.

As with most aggregate functions, NULL values are not aggregated, so three valued logic does not apply here.

SELECT
  bool_or(ID >= 4),
  bool_or(ID >= 5)
FROM BOOK
create.select(
         boolOr(BOOK.ID.ge(4)),
         boolOr(BOOK.ID.ge(5)))
      .from(BOOK)

Producing:

+---------+---------+
| bool_or | bool_or |
+---------+---------+
| true    | false   |
+---------+---------+

Dialect support

This example using jOOQ:

boolOr(BOOK.ID.ge(4))

Translates to the following dialect specific expressions:

Access

(max(SWITCH(BOOK.ID >= 4, 1, TRUE, 0)) = 1)

ASE, DB2, Firebird, SQLDataWarehouse, SQLServer, Sybase, Teradata

CASE
  WHEN max(CASE
    WHEN BOOK.ID >= 4 THEN 1
    ELSE 0
  END) = 1 THEN 1
  WHEN NOT (max(CASE
    WHEN BOOK.ID >= 4 THEN 1
    ELSE 0
  END) = 1) THEN 0
END

Aurora MySQL, Derby, H2, HSQLDB, MariaDB, MemSQL, MySQL, Redshift, SQLite

(max(CASE
  WHEN BOOK.ID >= 4 THEN 1
  ELSE 0
END) = 1)

bool_or((BOOK.ID >= 4))

BigQuery

logical_or((BOOK.ID >= 4))

  END) = 1) THEN FALSE
END

Informix

CASE
  WHEN max(CASE
    WHEN BOOK.ID >= 4 THEN 1
    ELSE 0
  END) = 1 THEN CAST('t' AS boolean)
  WHEN NOT (max(CASE
    WHEN BOOK.ID >= 4 THEN 1
