MySQL 如何使数字’易读’

要使数字’易读’，即包括分隔符，您需要使用format()。让我们首先创建一个表−

mysql> create table DemoTable859(Number bigint);
Query OK, 0 rows affected (1.54 sec)

使用insert命令将一些记录插入表中−

mysql> insert into DemoTable859 values(747464646473737);
Query OK, 1 row affected (0.45 sec)
mysql> insert into DemoTable859 values(3836365366464);
Query OK, 1 row affected (0.71 sec)
mysql> insert into DemoTable859 values(8376437647433);
Query OK, 1 row affected (0.46 sec)

使用select语句从表中显示所有记录−

mysql> select *from DemoTable859;

这将产生以下输出−

+-----------------+
| Number          |
+-----------------+
| 747464646473737 |
| 3836365366464   |
| 8376437647433   |
+-----------------+
3 rows in set (0.00 sec)

以下是在MySQL中使数字’易读’的查询−

mysql> select format(Number, 0) AS HumanReadableFormat from DemoTable859;

这将产生以下输出−

+---------------------+
| HumanReadableFormat |
+---------------------+
| 747,464,646,473,737 |
| 3,836,365,366,464   |
| 8,376,437,647,433   |
+---------------------+
3 rows in set (0.00 sec)
