How to search for exact string in MySQL?
You can use binary to search for exact string in MySQL. The syntax is as follows:
SELECT * FROM yourTableName WHERE BINARY yourColumnName = yourStringValue;
To understand the above syntax, let us create a table. The query to create a table is as follows:
mysql> create table ExactSearch -> ( -> Id int NOT NULL AUTO_INCREMENT, -> UserId varchar(10), -> UserName varchar(20), -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.69 sec)
Insert some records in the table using insert command. The query is as follows:
mysql> insert into ExactSearch(UserId,UserName) values('USER12','John');
Query OK, 1 row affected (0.11 sec)
mysql> insert into ExactSearch(UserId,UserName) values('12USER','Carol');
Query OK, 1 row affected (0.20 sec)
mysql> insert into ExactSearch(UserId,UserName) values('USER123','Bob');
Query OK, 1 row affected (0.15 sec)
mysql> insert into ExactSearch(UserId,UserName) values('USER231','Sam');
Query OK, 1 row affected (0.18 sec)Display all records from the table using select statement:
mysql> select *from ExactSearch;
The following is the output:
+----+---------+----------+ | Id | UserId | UserName | +----+---------+----------+ | 1 | USER12 | John | | 2 | 12USER | Carol | | 3 | USER123 | Bob | | 4 | USER231 | Sam | +----+---------+----------+ 4 rows in set (0.00 sec)
Here is the query to search for exact string in MySQL. We are searching for string “USER123”:
mysql> select *from ExactSearch where binary UserId = 'USER123';
The following is the output:
+----+---------+----------+ | Id | UserId | UserName | +----+---------+----------+ | 3 | USER123 | Bob | +----+---------+----------+ 1 row in set (0.00 sec)
