让我们首先创建一个表-
mysql> create table DemoTable1546 -> ( -> Number varchar(20) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1546 values('145 78 90'); mysql> insert into DemoTable1546 values('89 789 564 903'); mysql> insert into DemoTable1546 values('1345 7894 866 653534');
使用select语句显示表中的所有记录-
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,' ',''); 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)
