EVERY

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

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

TRUE if the argument is TRUE for every row in the group.
FALSE if at the argument is FALSE 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 
  every(ID < 4),
  every(ID < 5)
FROM BOOK

create.select(
         every(BOOK.ID.lt(4)),
         every(BOOK.ID.lt(5)))
      .from(BOOK)

Producing:

+---------------+---------------+
| every(ID < 4) | every(ID < 5) |
+---------------+---------------+
| false         | true          |  
+---------------+---------------+

Dialect support

This example using jOOQ:

every(BOOK.ID.lt(4))

Translates to the following dialect specific expressions:

-- ACCESS
(min(SWITCH(BOOK.ID < 4, 1, TRUE, 0)) = 1)

-- ASE, DB2, FIREBIRD, ORACLE, SQLDATAWAREHOUSE, SQLSERVER, SYBASE
CASE WHEN min(CASE WHEN BOOK.ID < 4 THEN 1 ELSE 0 END) = 1 THEN 1 WHEN NOT (min(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, TERADATA, VERTICA
(min(CASE WHEN BOOK.ID < 4 THEN 1 ELSE 0 END) = 1)

-- AURORA_POSTGRES, COCKROACHDB, POSTGRES
bool_and((BOOK.ID < 4))

-- BIGQUERY
logical_and((BOOK.ID < 4))

-- CUBRID, HANA, INGRES
CASE WHEN min(CASE WHEN BOOK.ID < 4 THEN 1 ELSE 0 END) = 1 THEN TRUE WHEN NOT (min(CASE WHEN BOOK.ID < 4 THEN 1 ELSE 0 END) = 1) THEN FALSE END

-- SNOWFLAKE
booland_agg((BOOK.ID < 4))
