      LIMIT

      LIMIT keeps the first N rows of data in the data stream, and discard the rest rows.

      Syntax: LIMIT <number>
      Input:

      • <number>: The number of rows to be kept, or to keep all rows when set to -1
      find().nodes([1, 5]) as nodes
      n(nodes).e()[:2].n() as path
      limit 2
      return path
      

      In the UQL above, LIMIT keeps the first 2 rows of path resulted from the template query:

      See UQL and image below to compare Clause LIMIT and Chain Command Parameter .limit()

      find().nodes([1, 5]) as nodes
      n(nodes).e()[:2].n().limit(2) as path
      return path
      

      Parameter .limit() keeps the first 2 rows of path resulted from each subquery of the template query:

      Common Usage

      Example: find all cards that transferred money to Card CA029, return 10 cards in a descending order of their balances; that is, to find the 10 cards with the highest balances

      n({_id == "CA029"}).le({@transfer}).n({@card} as n)
      with distinct (n)
      order by n.balance DESC
      return n{*} limit 10
