Append wildcards in SELECT with MySQL?
For appending, use the concept of concat(). The syntax is as follows −
select *from yourTableName where yourColumnName like concat('%',yourValue,'%');Let us create a table −
mysql> create table demo48 -> ( −> id int not null auto_increment primary key, −> name varchar(20) −> ); Query OK, 0 rows affected (0.70 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo48(name) values('John Smith');
Query OK, 1 row affected (0.12 sec)
mysql> insert into demo48(name) values('John Doe');
Query OK, 1 row affected (0.12 sec)
mysql> insert into demo48(name) values('Adam Smith');
Query OK, 1 row affected (0.23 sec)
mysql> insert into demo48(name) values('David Miller');
Query OK, 1 row affected (0.14 sec)
mysql> insert into demo48(name) values('Chris Brown');
Query OK, 1 row affected (0.11 sec)Display records from the table using select statement −
mysql> select *from demo48;
This will produce the following output −
+----+--------------+ | id | name | +----+--------------+ | 1 | John Smith | | 2 | John Doe | | 3 | Adam Smith | | 4 | David Miller | | 5 | Chris Brown | +----+--------------+ 5 rows in set (0.00 sec)
Following is the query to append wildcards in select statement −
mysql> select *from demo48 where name like concat('%','Smith','%');This will produce the following output −
+----+------------+ | id | name | +----+------------+ | 1 | John Smith | | 3 | Adam Smith | +----+------------+ 2 rows in set (0.00 sec)
