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)
