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:
-
FALSEif the argument isFALSEfor every row in the group. -
TRUEif at the argument isTRUEfor 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, 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)
-- AURORA_POSTGRES, COCKROACHDB, POSTGRES, VERTICA, YUGABYTEDB
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
-- 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
ELSE 0
END) = 1) THEN CAST('f' AS boolean)
END
-- SNOWFLAKE
