Search for specific characters within a string with MySQL?
For this, use REGEXP. For example, characters J, A, V and A. Let us first create a table −
mysql> create table DemoTable ( Value varchar(50) ); Query OK, 0 rows affected (3.92 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('XYSJGHAKLMVDFFSA');
Query OK, 1 row affected (0.67 sec)
mysql> insert into DemoTable values('PQRSTJAVAL');
Query OK, 1 row affected (0.58 sec)
mysql> insert into DemoTable values('SJATUVAK');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('JSTUVA');
Query OK, 1 row affected (0.32 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------------------+ | Value | +------------------+ | XYSJGHAKLMVDFFSA | | PQRSTJAVAL | | SJATUVAK | | JSTUVA | +------------------+ 4 rows in set (0.00 sec)
Following is the query to search for characters within a string with MySQL −
mysql> select *from DemoTable where Value REGEXP '.*J.*A.*V.*A';
This will produce the following output −
+------------------+ | Value | +------------------+ | XYSJGHAKLMVDFFSA | | PQRSTJAVAL | | SJATUVAK | +------------------+ 3 rows in set (0.00 sec)
