    startsWith()

    Function startsWith() judges whether a string starts with a specified substring, and returns 1 for true, 0 for false.

    Arguments:

    • String <string>
    • Substring <string>

    Returns:

    • Result <number>

    If the string and the sub string are non-homologous, Cartesian Product will be applied when the function is called in a WITH clause, or column length will be trimmed when called in a RETURN clause.

    Constant

    Example: judge if 'daS351sXFE51scf' starts with 'daS351s'

    return startsWith("daS351sXFE51scf", "daS351s")
    

    Function

    Example: judge if 'daS351sXFE51scf' in lowercase starts with 'das351s'

    return startsWith(lower("daS351sXFE51scf"), "daS351s")
    

    Alias

    Example: find 10 numbers and judge if those numbers start with 170

    find().nodes({@phone}) as n 
    limit 10
    return n.number, startsWith(n.number, "170") 
    

    Property

    Example: find 10 numbers that start with 170

    find().nodes({startsWith(@phone.number, "170")}) as n 
    limit 10
    return n.number
