MySQL query for alphabetical search (ABC) with REGEXP?

For alphabetic search, use the REGEX in MySQL. Here, let’s say we are searching for records beginning with A, B or C. The syntax to use REGEXP for the same purpose is as follows −

select *from yourTableName where yourColumnName REGEXP '^[ABC]';

Let us first create a table −

mysql> create table DemoTable
(
   Name varchar(100)
);
Query OK, 0 rows affected (0.69 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Bob');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('Adam');
Query OK, 1 row affected (0.14 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-------+
| Name  |
+-------+
| Chris |
| David |
| Mike  |
| Bob   |
| Mike  |
| Adam  |
+-------+
6 rows in set (0.00 sec)

Following is the query to perform an alphabetical search using REGEXP −

mysql> select *from DemoTable where Name REGEXP '^[ABC]';

This will produce the following output −

+-------+
| Name  |
+-------+
| Chris |
| Bob   |
| Adam  |
+-------+
3 rows in set (0.17 sec)
