      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 aliases 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
