In Mysql, when you execute a select SQL statement, there is a default ordering if you don't include a sorting clause, how to reverse the default ordering? Just add DESC?

推荐答案

如果要使数据一致地排序，则必须使用ORDER BY，后跟要作为查询排序依据的列. ASC是默认设置，因此您无需指定它. IE浏览器:

If you want the data to come out consistently ordered, you have to use ORDER BY followed by the column(s) you want to order the query by. ASC is the default, so you don't need to specify it. IE:

ORDER BY your_column

...等效于:

ORDER BY your_column ASC

ASC/DESC基于每一列.例如:

ASC/DESC is on a per column basis. For example:

ORDER BY first_column, second_column DESC

...表示查询将使用first_column升序，second_column降序将结果集作为组合排序.

...means that the query will sort the resultset as a combination using the first_column in ascending order, second_column in descending order.
