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)
