Match optional end of line after every record with REGEXP?
Let us first create a table −
mysql> create table DemoTable(EmployeeCode varchar(100)); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('EMPLOYEE:100 John Smith'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable values('EMPLOYEE:16537 Chris Brown'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('EMPLOYEE:100 David Miller'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('EMPLOYEE:100 23432 David Miller'); Query OK, 1 row affected (0.20 sec)
Display all records from the table using select statement −
mysql>; select *from DemoTable;
This will produce the following output −
+---------------------------------+ | EmployeeCode | +---------------------------------+ | EMPLOYEE:100 John Smith | | EMPLOYEE:16537 Chris Brown | | EMPLOYEE:100 David Miller | | EMPLOYEE:100 23432 David Miller | +---------------------------------+ 4 rows in set (0.00 sec)
Following is the query to match optional end of line, for example, 23434 after 100 in “EMPLOYEE:100 23432 David Miller” −
mysql> select *from DemoTable where EmployeeCode REGEXP "EMPLOYEE:100([^0-9]|$)";
This will produce the following output −
+---------------------------------+ | EmployeeCode | +---------------------------------+ | EMPLOYEE:100 John Smith | | EMPLOYEE:100 David Miller | | EMPLOYEE:100 23432 David Miller | +---------------------------------+ 3 rows in set (0.00 sec)
