如何在MySQL查询中将MySQL长文本视为整数？
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)
