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('[email protected]'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('[email protected]'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable values('[email protected]'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable values('[email protected]'); Query OK, 1 row affected (0.43 sec) mysql> insert into DemoTable values('[email protected]'); 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 | +----------------------------+ | [email protected] | | [email protected] | | [email protected] | | [email protected] | | [email protected] | +----------------------------+ 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 | +----------------------------+ | [email protected] | | [email protected] | +----------------------------+ 2 rows in set (0.00 sec)
