LIMIT clause

      +
      The LIMIT clause specifies the maximum number of documents to be returned in a resultset by a SELECT statement.

      Purpose

      When you don’t need the entire resultset, use the LIMIT clause to specify the maximum number of documents to be returned in a resultset by a SELECT query.

      The LIMIT and OFFSET clauses are evaluated after the ORDER BY clause.

      A negative value is the same as LIMIT 0.

      Starting from version 4.5, the LIMIT clause in INSERT, UPDATE, and DELETE statements is no longer a hint. It indicates that the actual number of mutations will be less than or equal to the specified LIMIT.

      Syntax

      LIMIT expr
      limit clause

      Arguments

      expr

      Integer or an expression that evaluates to an integer representing the number of resulting documents.

      Examples

      Example 1: Get only 2 documents of hotels with an empty room.

      SELECT name, address, city, country, url
      FROM `travel-sample`
      WHERE type="hotel"
        AND vacancy = true
      LIMIT 2;

      Result:

      [
        {
          "address": "Capstone Road, ME7 3JE",
          "city": "Medway",
          "country": "United Kingdom",
          "name": "Medway Youth Hostel",
          "url": "http://www.yha.org.uk"
        },
        {
          "address": "6 rue aux Juifs",
          "city": "Giverny",
          "country": "France",
          "name": "The Robins",
          "url": "http://givernyguesthouse.com/robin.htm"
        }
      ]

      Example 2: Set the limit of Example 1 based on an equation.

      SELECT name, address, city, country, url
      FROM `travel-sample`
      WHERE type="hotel"
        AND vacancy = true
      LIMIT (20/10);

      Result:

      [
        {
          "address": "Capstone Road, ME7 3JE",
          "city": "Medway",
          "country": "United Kingdom",
          "name": "Medway Youth Hostel",
          "url": "http://www.yha.org.uk"
        },
        {
          "address": "6 rue aux Juifs",
          "city": "Giverny",
          "country": "France",
          "name": "The Robins",
          "url": "http://givernyguesthouse.com/robin.htm"
        }
