Given a string or a number, contains function will check for a specified substring in it.

Syntax

output = contains(expression, searchText)

Inputs

expression : a reference to a variable or any [[expression|Expressions]].

searchText : A substring or a number to search from input expression value.

Output

output : A boolean depending on if substring is found or not in the input expression value.

Example flow

Schema splitWordSchema {
    boolean containsInString
    boolean containsInNumber
    boolean containsStringNum
    boolean containsNumString
}

Schema wordSchema {
    string recipes
    string strNum
    number num
}

value dummyWord -> wordSchema {
    "GTKM=B&RTP=B"
    "GTKM=B&RTP=B89"
    8766756
}

Mapping containsMapping input dummyWord as dummyWord output splitWordSchema {
    splitWordSchema.containsInString =    contains(dummyWord.recipes, "RTP=B")
    splitWordSchema.containsInNumber =    contains(dummyWord.num, 7)
    splitWordSchema.containsStringNum =    contains(dummyWord.num, "7")
    splitWordSchema.containsNumString =    contains(dummyWord.strNum, "8")
}

Output for Example Flow

{
    "containsInString": true,
    "containsInNumber": true,
    "containsStringNum": true,
    "containsNumString": true
}
