  • grails通过findBy或findBy查找的结果集进行排序

    原文:http://grails.org/doc/2.3.x/ref/Domain%20Classes/list.html

    list

    Purpose

    Lists instances of the domain class.

    Examples

    // list everything
    def results = Book.list()

    // list 10 results def results = Book.list(max: 10)

    // list 10 results, offset by 100 def results = Book.list(max: 10, offset: 100)

    // list 10 results, offset by 100, orderd by title in descending order def results = Book.list(max: 10, offset: 100, sort: "title", order: "desc")

    // list all books, eagerly fetching the authors association def results = Book.list(fetch: [authors: "eager"])

    When max is specified as a named argument this will return a PagedResultList which has a getTotalCount() method to return the total number of matching records for pagination. Two queries are still run, but they're run for you and the results and total count are combined in the PagedResultList.

    Description

    • max - The maximum number to list,要列出的最大数目
    • offset - The offset from the first result to list from
    • order - How to order the list, either "desc" or "asc",排序方式

    • fetchSize - number of rows fetched by the underlying JDBC driver per round trip
    • flushMode - Hibernate FlushMode override, defaults to FlushMode.AUTO
