How to strip all spaces from a column in MySQL?
To strip all spaces from a column in MySQL, you can use REPLACE() function. Following is the syntax −
update yourTableName set yourColumnName=REPLACE(yourColumnName,' ', '' );
Let us first create a table −
mysql> create table stripAllSpacesDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.56 sec)
Following is the query to insert records in the table using insert command −
mysql> insert into stripAllSpacesDemo(Name) values('Jo h n');
Query OK, 1 row affected (0.19 sec)
mysql> insert into stripAllSpacesDemo(Name) values(' Joh n');
Query OK, 1 row affected (0.16 sec)
mysql> insert into stripAllSpacesDemo(Name) values('Jo hn');
Query OK, 1 row affected (0.14 sec)
mysql> insert into stripAllSpacesDemo(Name) values('J ohn');
Query OK, 1 row affected (0.17 sec)
mysql> insert into stripAllSpacesDemo(Name) values('John ');
Query OK, 1 row affected (0.14 sec)Following is the query to display all records from the table using select statement −
mysql> select * from stripAllSpacesDemo;
This will produce the following output −
+----+-----------+ | Id | Name | +----+-----------+ | 1 | Jo h n | | 2 | Joh n | | 3 | Jo hn | | 4 | J ohn | | 5 | John | +----+-----------+ 5 rows in set (0.00 sec)
Here is the query to strip all spaces from column in MySQL −
mysql> update stripAllSpacesDemo set Name=REPLACE(Name,' ',''); Query OK, 5 rows affected (0.12 sec) Rows matched: 5 Changed: 5 Warnings: 0
Let us display all records from the table once again to check all spaces have been stripped or not −
mysql> select * from stripAllSpacesDemo;
This will produce the following output −
+----+------+ | Id | Name | +----+------+ | 1 | John | | 2 | John | | 3 | John | | 4 | John | | 5 | John | +----+------+ 5 rows in set (0.00 sec)
