You can use Like operator for working with % wildcard. The syntax is as follows
select *from yourTableName where yourColumName Like ‘condition%’;
To understand the above concept, let us first create a table. The query to create a table
mysql> create table SearchDemo -> ( -> Name varchar(100), -> LoginId varchar(100) -> ); Query OK, 0 rows affected (1.15 sec)
Insert some records in the table using insert command. The query is as follows
mysql> insert into SearchDemo values('John','1_1'); Query OK, 1 row affected (0.19 sec) mysql> insert into SearchDemo values('Johnson','1_2'); Query OK, 1 row affected (0.19 sec) mysql> insert into SearchDemo values('Carol','2_1'); Query OK, 1 row affected (0.12 sec) mysql> insert into SearchDemo values('Bob','11_1'); Query OK, 1 row affected (0.19 sec) mysql> insert into SearchDemo values('Sam','11_2'); Query OK, 1 row affected (0.25 sec) mysql> insert into SearchDemo values('Mike','21_1'); Query OK, 1 row affected (0.22 sec)
Display all records from the table using select statement. The query is as follows
mysql> select *from SearchDemo;
The following is the output
+---------+---------+ | Name | LoginId | +---------+---------+ | John | 1_1 | | Johnson | 1_2 | | Carol | 2_1 | | Bob | 11_1 | | Sam | 11_2 | | Mike | 21_1 | +---------+---------+ 6 rows in set (0.00 sec)
The % is a type of wildcard that represents zero, one, or multiple characters. The query is as follows using the % wildcard
mysql> select *from SearchDemo -> where LoginId Like '2%';
The following is the output
+-------+---------+ | Name | LoginId | +-------+---------+ | Carol | 2_1 | | Mike | 21_1 | +-------+---------+ 2 rows in set (0.00 sec)
