This well-order, sometimes called shortlex or quasi-lexicographical order, consists in considering first the lengths of the words (if length(a) < length(b), then <), and, if the lengths are equal, using the lexicographical order. If the order on A is a well-order, the same is true for the shortlex order. [2] [3]
Clicking on the up/down arrows in a column header will sort the column; clicking again will reverse the sort. Text is sorted alphabetically. Numbers are sorted numerically. Mixed data is sorted alphabetically. For advanced sort options, see Help:Sorting
An ORDER BY clause in SQL specifies that a SQL SELECT statement returns a result set with the rows being sorted by the values of one or more columns. The sort criteria does not have to be included in the result set (restrictions apply for SELECT DISTINCT, GROUP BY, UNION [DISTINCT], EXCEPT [DISTINCT] and INTERSECT [DISTINCT].)
Merge sort. In computer science, a sorting algorithm is an algorithm that puts elements of a list into an order.The most frequently used orders are numerical order and lexicographical order, and either ascending or descending.
The sort-merge join (also known as merge join) is a join algorithm and is used in the implementation of a relational database management system.. The basic problem of a join algorithm is to find, for each distinct value of the join attribute, the set of tuples in each relation which display that value.
In mathematics, lexicographical order is a means of ordering sequences in a manner analogous to that used to produce alphabetical order. [16] Some computer applications use a version of alphabetical order that can be achieved using a very simple algorithm, based purely on the ASCII or Unicode codes for characters. This may have non-standard ...
Sorting your emails from your folders has never been easier in AOL Mail. Use the sorting feature regardless of the folder you are in to rearrange the emails and find the ones important, click on Sort on top right of your emails list and choose the option that best suits your need. • Date - Newest on top. • Date - Oldest on top.
data-sort-type=number is a good idea in that table because some people may forget to add the data-sort-value in some cases. This could mess up sorting in some very particular cases. Too long to explain. See the fine print here: Help:Sortable tables#Examples of datatype auto detection. First 5 cells in a column.
