具有空格数字的 MySQL 查询来格式化数字?
我们首先创建一个表 -
mysql> create table DemoTable1546 -> ( -> Number varchar(20) -> ); Query OK, 0 rows affected (0.99 sec)
使用插入命令在表中插入一些记录 -
mysql> insert into DemoTable1546 values('145 78 90'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1546 values('89 789 564 903'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1546 values('1345 7894 866 653534'); Query OK, 1 row affected (0.12 sec)
使用 select 语句从表中显示所有记录 -
mysql> select * from DemoTable1546;
这将产生以下输出 -
+----------------------+ | Number | +----------------------+ | 145 78 90 | | 89 789 564 903 | | 1345 7894 866 653534 | +----------------------+ 3 rows in set (0.00 sec)
以下是通过替换数字之间的空格来格式化数字的查询 -
mysql> update DemoTable1546 set Number=replace(Number,' ',''); Query OK, 3 rows affected (0.13 sec) Rows matched: 3 Changed: 3 Warnings: 0
让我们再次检查表记录 -
mysql> select * from DemoTable1546;
这将产生以下输出 -
+-------------------+ | Number | +-------------------+ | 1457890 | | 89789564903 | | 13457894866653534 | +-------------------+ 3 rows in set (0.00 sec)
