The jOOQ User Manual : SQL building : Column expressions : Aggregate functions : EVERY | previous : next |

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 isTRUE
for every row in the group. -
FALSE
if at the argument isFALSE
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))
(These are currently generated with jOOQ 3.15, see #10141)
