How do I exclude a specific record in MySQL?
You can exclude a specific record in SQL using not equal to operator(!=). Let us first create a table−
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, ClientName varchar(20), ClientCountryName varchar(10) ); Query OK, 0 rows affected (0.64 sec)
Insert records in the table using insert command −
mysql> insert into DemoTable(ClientName,ClientCountryName) values('John','US'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable(ClientName,ClientCountryName) values('David','AUS'); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable(ClientName,ClientCountryName) values('Mike','UK'); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+------------+-------------------+ | Id | ClientName | ClientCountryName | +----+------------+-------------------+ | 1 | John | US | | 2 | David | AUS | | 3 | Mike | UK | +----+------------+-------------------+ 3 rows in set (0.00 sec)
Following is the query to exclude a specific record in MySQL i.e. we are excluding records with ClientName David' or ClientCountryName ='AUS'−
mysql> select *from DemoTable where ClientName!='David' or ClientCountryName!='AUS';
This will produce the following output−
+----+------------+-------------------+ | Id | ClientName | ClientCountryName | +----+------------+-------------------+ | 1 | John | US | | 3 | Mike | UK | +----+------------+-------------------+ 2 rows in set (0.00 sec)
