Let us first create a table −
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY , Title text ); Query OK, 0 rows affected (0.88 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(Title) values('This is; a; MySQL;Tutorial'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable(Title) values('Java is; an;Object Oriented'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable(Title) values('MongoDB ; is;a; database'); Query OK, 1 row affected (0.12 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+-----------------------------+ | Id | Title | +----+-----------------------------+ | 1 | This is; a; MySQL;Tutorial | | 2 | Java is; an;Object Oriented | | 3 | MongoDB ; is;a; database | +----+-----------------------------+ 3 rows in set (0.00 sec)
Here is the regex to find lines containing 3 semi-colons −
mysql> select *from DemoTable where Title REGEXP '(.*;){3}';
This will produce the following output −
+----+----------------------------+ | Id | Title | +----+----------------------------+ | 1 | This is; a; MySQL;Tutorial | | 3 | MongoDB ; is;a; database | +----+----------------------------+ 2 rows in set (0.00 sec)
