How to restrict MySQL `LIKE` operator to begin with specific characters?
Let us first create a table −
mysql> create table DemoTable
(
FirstName varchar(40)
);
Query OK, 0 rows affected (0.52 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable values('Adam');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values('Sam');
Query OK, 1 row affected (0.09 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-----------+
|FirstName |
+-----------+
| John |
| Adam |
| David |
| Mike |
| Sam |
+-----------+
5 rows in set (0.00 sec)
Following is the query to restrict `LIKE` operator to begin with specific characters −
mysql> select *from DemoTable where FirstName LIKE 'D%' or FirstName LIKE 'S%';
This will produce the following output −
+-----------+
| FirstName |
+-----------+
| David |
| Sam |
+-----------+
2 rows in set (0.00 sec)
