How to escape parentheses in MySQL REGEXP clause and display only specific values with parentheses?

Let us first create a table −

mysql> create table DemoTable1908    (    Code text    ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1908 values('MySQL(1)Database'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1908 values('MongoDB 2 Database'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1908 values('MySQL(3)Database'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1908 values('SQL Server(10)Database'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1908 values('MySQL 8 Database'); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1908;

This will produce the following output −

+------------------------+ | Code                   | +------------------------+ | MySQL(1)Database       | | MongoDB 2 Database     | | MySQL(3)Database       | | SQL Server(10)Database | | MySQL 8 Database       | +------------------------+ 5 rows in set (0.00 sec)

Here is the query to escape parentheses in a REGEXP clause and display only the paratheses value with () −

mysql> select * from DemoTable1908 where Code regexp '^MySQL[(][0-9][)]Database';

This will produce the following output −

+------------------+ | Code             | +------------------+ | MySQL(1)Database | | MySQL(3)Database | +------------------+ 2 rows in set (0.00 sec)
