让我们首先创建一个表-

mysql> create table DemoTable
   -> (
   -> Value longtext
   -> );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable values('778437437447488487476464644433334');
mysql> insert into DemoTable values('9998888485775775757577578585');
mysql> insert into DemoTable values('8888874757757757757757575675656');
mysql> insert into DemoTable values('988757757574646');

使用select语句显示表中的所有记录-

mysql> select * from DemoTable;

这将产生以下输出-

+-----------------------------------+
| Value                             |
+-----------------------------------+
| 778437437447488487476464644433334 |
| 9998888485775775757577578585      |
| 8888874757757757757757575675656   |
| 988757757574646                   |
+-----------------------------------+
4 rows in set (0.00 sec)

这是将MySQL长文本视为查询中的整数的查询-

mysql> select * from DemoTable
   -> order by Value+0;

这将产生以下输出-

+-----------------------------------+
| Value                             |
+-----------------------------------+
| 988757757574646                   |
| 9998888485775775757577578585      |
| 8888874757757757757757575675656   |
| 778437437447488487476464644433334 |
+-----------------------------------+
4 rows in set (0.03 sec)
