How to change a specific char in a MySQL string?
To change a specific char in a MySQL string, you can use CONCAT() along with SUBSTRING().
Let us first create a table −
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Value varchar(200) ); Query OK, 0 rows affected (0.60 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(Value) values('98764');
Query OK, 1 row affected (0.17 sec)Following is the query to display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+-------+ | Id | Value | +----+-------+ | 1 | 98764 | +----+-------+ 1 row in set (0.00 sec)
Here is the query to change a specific char in a MySQL string. We have set X here where 6 was placed −
mysql> select concat(substring(Value,1,3),'X',substring(Value,5)) from DemoTable;
This will produce the following output −
+-----------------------------------------------------+ | concat(substring(Value,1,3),'X',substring(Value,5)) | +-----------------------------------------------------+ | 987X4 | +-----------------------------------------------------+ 1 row in set (0.00 sec)
