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, ORACLE, SQLDATAWAREHOUSE, SQLSERVER, SYBASE
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, IGNITE, INFORMIX, MARIADB, MEMSQL, MYSQL, REDSHIFT, SQLITE
(max(CASE
  WHEN BOOK.ID >= 4 THEN 1
  ELSE 0
END) = 1)

-- AURORA_POSTGRES, COCKROACHDB, POSTGRES, VERTICA, YUGABYTE
bool_or((BOOK.ID >= 4))

-- BIGQUERY
logical_or((BOOK.ID >= 4))

-- EXASOL
any((BOOK.ID >= 4))

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

-- SNOWFLAKE
boolor_agg((BOOK.ID >= 4))

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