Logical quantifier functions

Logical quantifiers can be used to assert conditions with arrays in Profile Query Language (PQL). More information about other PQL functions can be found in the Profile Query Language overview .

Exists

The exists function determines the existence of an item in an array, provided it satisfies the provided condition.
Format
exists {VARIABLE} from {EXPRESSION} where {CONDITION}
exists {VARIABLE} from {EXPRESSION} : {CONDITION}

Argument
Description
{VARIABLE}
A name of a variable.
{EXPRESSION}
The array which is being checked.
{CONDITION}
An optional expression which filters the values in the array returned.
Example
The following PQL query gets all events which has a price greater than $50 or has a SKU of "PS".
exists E from xEvent where (E.commerce.item.price > 50), I from E.productListItems where I.SKU = "PS"

For all

The forall function determines all items in an array that satisfy all the given conditions.
Format
forall {VARIABLE} from {EXPRESSION} where {CONDITION}
forall {VARIABLE} from {EXPRESSION} : {CONDITION}

Argument
Description
{VARIABLE}
A name of a variable.
{EXPRESSION}
The array which is being checked.
{CONDITION}
An optional expression which filters the values in the array returned.
Example
The following PQL query gets all events which has a price greater than $50 and has a SKU of "PS".
forall E from xEvent where (E.commerce.item.price > 50), I from E.productListItems where I.SKU = "PS"
