Select all email addresses beginning with 5 numeric characters (regular expression) in MySQL
To get the email addresses beginning with 5 numeric characters, the optional solution is to use REGEXP −
select *from yourTableName where yourColumnName regexp "^[0-9]{5}";Let us first create a table −
mysql> create table DemoTable ( UserEmailAddress varchar(100) ); Query OK, 0 rows affected (0.76 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('6574John@gmail.com');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Carol23456@gmail.com');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('98989Chris_45678@gmail.com');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Mike12@gmail.com');
Query OK, 1 row affected (0.43 sec)
mysql> insert into DemoTable values('56453Adam@gmail.com');
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 −
+----------------------------+ | UserEmailAddress | +----------------------------+ | 6574John@gmail.com | | Carol23456@gmail.com | | 98989Chris_45678@gmail.com | | Mike12@gmail.com | | 56453Adam@gmail.com | +----------------------------+ 5 rows in set (0.00 sec)
Following is the query to select all email addresses beginning with 5 numeric characters −
mysql> select *from DemoTable where UserEmailAddress regexp "^[0-9]{5}";This will produce the following output −
+----------------------------+ | UserEmailAddress | +----------------------------+ | 98989Chris_45678@gmail.com | | 56453Adam@gmail.com | +----------------------------+ 2 rows in set (0.00 sec)
