Is there an operator in MySQL to implement multiple NOT conditions like WHERE id != 5 AND id != 10 AND id != 15?
Yes, for this MySQL comes with a NOT IN.
The syntax is as follows
SELECT *FROM yourTableName WHERE yourColumnName NOT IN(1,2,7);
To understand the above syntax, let us create a table. The query to create a table is as follows
mysql> create table User_informations - > ( - > UserId int, - > UserName varchar(20) - > ); Query OK, 0 rows affected (0.47 sec)
Insert some records in the table using insert command.
The query is as follows
mysql> insert into User_informations values(12,'Maxwell'); Query OK, 1 row affected (0.17 sec) mysql> insert into User_informations values(7,'David'); Query OK, 1 row affected (0.10 sec) mysql> insert into User_informations values(1,'Ramit'); Query OK, 1 row affected (0.36 sec) mysql> insert into User_informations values(10,'Bob'); Query OK, 1 row affected (0.19 sec) mysql> insert into User_informations values(2,'Carol'); Query OK, 1 row affected (0.14 sec) mysql> insert into User_informations values(14,'Sam'); Query OK, 1 row affected (0.23 sec) mysql> insert into User_informations values(6,'Mike'); Query OK, 1 row affected (0.12 sec) mysql> insert into User_informations values(4,'Robert'); Query OK, 1 row affected (0.13 sec)
Display all records from the table using select statement.
The query is as follows
mysql> select *from User_informations;
The following is the output
+--------+----------+ | UserId | UserName | +--------+----------+ | 12 | Maxwell | | 7 | David | | 1 | Ramit | | 10 | Bob | | 2 | Carol | | 14 | Sam | | 6 | Mike | | 4 | Robert | +--------+----------+ 8 rows in set (0.00 sec)
The following is the implementation of what you asked using NOT IN().
The query is as follows
mysql> select *from User_informations where UserId NOT IN(1,2,7);
The following is the output
+--------+----------+ | UserId | UserName | +--------+----------+ | 12 | Maxwell | | 10 | Bob | | 14 | Sam | | 6 | Mike | | 4 | Robert | +--------+----------+ 5 rows in set (0.00 sec)
