Update a column of text with MySQL REPLACE()
Let us first create a table −
mysql> create table DemoTable ( Code varchar(100) ); Query OK, 0 rows affected (0.50 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('8565-9848-7474');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('9994-6464-8737');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('6574-9090-7643');
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----------------+ | Code | +----------------+ | 8565-9848-7474 | | 9994-6464-8737 | | 6574-9090-7643 | +----------------+ 3 rows in set (0.00 sec)
Following is the query to replace column value −
mysql> update DemoTable set Code=replace(Code,'9994-6464-8737','9994-9999-88888'); Query OK, 1 row affected (0.10 sec) Rows matched : 3 Changed : 1 Warnings : 0
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+-----------------+ | Code | +-----------------+ | 8565-9848-7474 | | 9994-9999-88888 | | 6574-9090-7643 | +-----------------+ 3 rows in set (0.00 sec)
