MySQL REGEXP to fetch string + number records beginning with specific numbers?
For this, use REGEXP and fetch records beginning with specific numbers. Following is the syntax:
Select yourColumnName1,yourColumnName2 from yourTableName where yourColumnName2 REGEXP '^yourStringValue[yourNumericValue]';
Let us create a table −
mysql> create table demo45 -> ( −> id int not null auto_increment primary key, −> value varchar(50) −> ); Query OK, 0 rows affected (1.50 sec)
Insert some records into the table with the help of insert command. We are inserting records mixed with strings and numbers i.e. “John500, “John6500”, etc −
mysql> insert into demo45(value) values('John500');
Query OK, 1 row affected (0.12 sec)
mysql> insert into demo45(value) values('John1500');
Query OK, 1 row affected (0.11 sec)
mysql> insert into demo45(value) values('John5500');
Query OK, 1 row affected (0.42 sec)
mysql> insert into demo45(value) values('John6500');
Query OK, 1 row affected (0.10 sec)
mysql> insert into demo45(value) values('John8600');
Query OK, 1 row affected (0.19 sec)Display records from the table using select statement −
mysql> select *from demo45;
This will produce the following output −
+----+----------+ | id | value | +----+----------+ | 1 | John500 | | 2 | John1500 | | 3 | John5500 | | 4 | John6500 | | 5 | John8600 | +----+----------+ 5 rows in set (0.00 sec)
Following is the query to fetch records with specific numbers i.e. 5 and 6 here −
mysql> select id,value −> from demo45 −> where value REGEXP '^John[56]';
This will produce the following output −
+----+----------+ | id | value | +----+----------+ | 1 | John500 | | 3 | John5500 | | 4 | John6500 | +----+----------+ 3 rows in set (0.00 sec)
