Concatenating two strings in MySQL with space?
For this, you can use concat() function from MySQL. Let us first create a table −
mysql> create table DemoTable -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(20), -> Subject varchar(100) -> ); Query OK, 0 rows affected (17.73 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(Name,Subject) values('John','MySQL');
Query OK, 1 row affected (1.19 sec)
mysql> insert into DemoTable(Name,Subject) values('Chris','SQL Server');
Query OK, 1 row affected (0.88 sec)
mysql> insert into DemoTable(Name,Subject) values('Robert','MongoDB');
Query OK, 1 row affected (2.62 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+----+--------+------------+ | Id | Name | Subject | +----+--------+------------+ | 1 | John | MySQL | | 2 | Chris | SQL Server | | 3 | Robert | MongoDB | +----+--------+------------+ 3 rows in set (0.00 sec)
Here is the query to concatenate two strings with space −
mysql> update DemoTable -> set Subject=concat(Name,' ',Subject); Query OK, 3 rows affected (0.38 sec) Rows matched: 3 Changed: 3 Warnings: 0
Let us check all records from the table −
mysql> select *from DemoTable;
Output
+----+--------+------------------+ | Id | Name | Subject | +----+--------+------------------+ | 1 | John | John MySQL | | 2 | Chris | Chris SQL Server | | 3 | Robert | Robert MongoDB | +----+--------+------------------+ 3 rows in set (0.00 sec)
