Regex to find string and next character in a comma separated list - MySQL?
To search in a comma separated list, use MySQL find_in_set(). The usage of Regex for this purpose isn’t required here. The syntax is as follows −
select *from yourTableName where find_in_set(anyValue,yourColumnName);
Let us create a table −
mysql> create table demo17
−> (
−> id int not null auto_increment primary key,
−> first_name varchar(50),
−> value text
−> );
Query OK, 0 rows affected (1.81 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo17(first_name,value) values('John','50');
Query OK, 1 row affected (0.11 sec)
mysql> insert into demo17(first_name,value) values('David','');
Query OK, 1 row affected (0.13 sec)
mysql> insert into demo17(first_name,value) values('Adam','50,89');
Query OK, 1 row affected (0.14 sec)
mysql> insert into demo17(first_name,value) values('Adam','49,89,43');
Query OK, 1 row affected (0.20 sec)Display records from the table using select statement −
mysql> select *from demo17;
This will produce the following output −
+----+------------+----------+
| id | first_name | value |
+----+------------+----------+
| 1 | John | 50 |
| 2 | David | |
| 3 | Adam | 50,89 |
| 4 | Adam | 49,89,43 |
+----+------------+----------+
4 rows in set (0.00 sec)
Following is the query to find string and next character −
mysql> select *from demo17 where find_in_set(50,value);
This will produce the following output −
+----+------------+-------+
| id | first_name | value |
+----+------------+-------+
| 1 | John | 50 |
| 3 | Adam | 50,89 |
+----+------------+-------+
2 rows in set (0.00 sec)
