      Not Equal

      Expression, Operand

      != judges whether one given value is not equal to another value.

      Syntax:

      • Expression: <value1> != <value2>
      • Operator: ATTR (string, number, time)

      ATTR

      Example: judge whether "Ultipa" is not equal to "Ultipa"

      return "Ultipa" != "U1tipa"
      

      Function

      Example: judge whether PI does not equal 3

      return pi() != 3
      

      Alias

      Example: find nodes whose levels are not 1, return 10 nodes with all properties

      find().nodes() as n
      where n.level != 1
      limit 10
      return n{*}
      

      Analysis: both nodes that do not have @level property and nodes whose @level do not equal 1 will be filtered

      Property

      Example: Find information of 10 nodes that are not bank cards

      find().nodes({level != 1}) as n
      limit 10
      return n{*} 
      

      Analysis: another expression of this filter is {!@card}, see Logic Operator !.

      Example: Find 10 bank cards whose level is not 1

      find().nodes({level != 1}) as n
      limit 10
      return n{*} 
      

      Example: Find 10 customers whose level is not 1

      find().nodes({@customer.level != 1}) as n
      limit 10
      return n{*}
