在MySQL中用数字混合排序的字符串？
在某些情况下，请使用ORDERBY。让我们创建一个表-
mysql> create table demo18 −> ( −> value text −> );
借助insert命令将一些记录插入表中-
mysql> insert into demo18 values('John Smith');
mysql> insert into demo18 values('2J John has 58');
mysql> insert into demo18 values('2J John has 9');使用select语句显示表中的记录-
mysql> select *from demo18;
这将产生以下输出-
+----------------+ | value | +----------------+ | John Smith | | 2J John has 58 | | 2J John has 9 | +----------------+ 3 rows in set (0.00 sec)
以下是要排序的查询-
mysql> select *from demo18 −> order by regexp_replace(value, '[0&minus9]*$', ''), −> length(value), −> value;
这将产生以下输出-
+----------------+ | value | +----------------+ | 2J John has 9 | | 2J John has 58 | | John Smith | +----------------+ 3 rows in set (0.14 sec)
