The OR of two lists of filters. For example:
selectList
([ PersonAge >. 25
, PersonAge <. 30 ] ||.
[ PersonIncome >. 15000
, PersonIncome <. 25000 ])
[]
will filter records where a person's age is between 25 and 30 or a person's income is between (15000 and 25000). If you are looking for an (&&.) operator to do (A AND B AND (C OR D)) you can use the (++) operator instead as there is no (&&.). For example:
selectList
([ PersonAge >. 25
, PersonAge <. 30 ] ++
([PersonCategory ==. 1] ||.
[PersonCategory ==. 5]))
[]
will filter records where a person's age is between 25 and 30 and (person's category is either 1 or 5).
