Description

Return true if a given value matches any value in a list of candidates, otherwise return false.

Syntax

Like many functions in DataPrime, in supports two notations, function and method. These interchangeable forms allow flexibility in how you structure expressions.

Function notation

in(comparand: any, value: any, ...values: any): bool

Method notation

(comparand: any).in(value: any, ...values: any): bool

Arguments

Name	Type	Required	Description
comparand	any	true	The value to check
value	any	true	The first candidate to compare against
...values	any	true	Additional candidates to compare against

Example

Use case: Flag membership in a predefined group

A team name can be compared against a list of department members to determine if it belongs to Engineering.

Example data

{
    "team": "Developers"
},
{
    "team": "Marketing"
},
{
    "team": "QA Testing"
}

Example query

Function notation

create is_in_engineering from in(team, 'Developers', 'QA Testing', 'Front End Engineers', 'DevOps Team')

Method notation

create is_in_engineering from team.in('Developers', 'QA Testing', 'Front End Engineers', 'DevOps Team')

Example output

{
    "team": "Developers",
    "is_in_engineering": true
},
{
    "team": "Marketing",
    "is_in_engineering": false
},
{
    "team": "QA Testing",
    "is_in_engineering": true
}
