MySQL query to format numbers which has space between digit?

Let us first create a table −

mysql> create table DemoTable1546    -> (    -> Number varchar(20)    -> ); Query OK, 0 rows affected (0.99 sec)

Insert some records in the table using insert command −

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)

Display all records from the table using select statement −

mysql> select * from DemoTable1546;

This will produce the following output −

+----------------------+ | Number               | +----------------------+ | 145 78 90            | | 89 789 564 903       | | 1345 7894 866 653534 | +----------------------+ 3 rows in set (0.00 sec)

Following is the query to format numbers by replacing space between numbers −

mysql> update DemoTable1546 set Number=replace(Number,' ',''); Query OK, 3 rows affected (0.13 sec) Rows matched: 3  Changed: 3 Warnings: 0

Let us check the table records once again −

mysql> select * from DemoTable1546;

This will produce the following output −

+-------------------+ | Number            | +-------------------+ | 1457890           | | 89789564903       | | 13457894866653534 | +-------------------+ 3 rows in set (0.00 sec)
