Correctly implement the AND condition in MySQL
To implement AND condition, the syntax is as follows −
select *from yourTableName where yourColumnName1 = yourValue1 AND yourColumnName2 = yourValue2;
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table MySQLANDConditionDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(100), -> Age int -> ); Query OK, 0 rows affected (0.80 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into MySQLANDConditionDemo(Name,Age) values('Larry',23); Query OK, 1 row affected (0.11 sec) mysql> insert into MySQLANDConditionDemo(Name,Age) values('Mike',21); Query OK, 1 row affected (0.17 sec) mysql> insert into MySQLANDConditionDemo(Name,Age) values('Sam',24); Query OK, 1 row affected (0.17 sec) mysql> insert into MySQLANDConditionDemo(Name,Age) values('David',26); Query OK, 1 row affected (0.17 sec) mysql> insert into MySQLANDConditionDemo(Name,Age) values('Carol',27); Query OK, 1 row affected (0.11 sec) mysql> insert into MySQLANDConditionDemo(Name,Age) values('Bob',28); Query OK, 1 row affected (0.19 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from MySQLANDConditionDemo;
Here is the output −
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 1 | Larry | 23 | | 2 | Mike | 21 | | 3 | Sam | 24 | | 4 | David | 26 | | 5 | Carol | 27 | | 6 | Bob | 28 | +----+-------+------+ 6 rows in set (0.00 sec)
The following is the query for MySQL AND condition −
mysql> select *from MySQLANDConditionDemo where Name ='Mike' AND Age =21;
Here is the output −
+----+------+------+ | Id | Name | Age | +----+------+------+ | 2 | Mike | 21 | +----+------+------+ 1 row in set (0.00 sec)
