MySQL query to get a field value that does not contain empty spaces?
Use NOT LIKE for this. Let us first create a table −
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentFullName varchar(40) ); Query OK, 0 rows affected (0.66 sec)
Insert records in the table using insert command −
mysql> insert into DemoTable(StudentFullName) values('JohnSmith');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable(StudentFullName) values('John Doe');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable(StudentFullName) values('Adam Smith');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable(StudentFullName) values('CarolTaylor');
Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement −
mysql> select * from DemoTable;
This will produce the following output −
+----+-----------------+ | Id | StudentFullName | +----+-----------------+ | 1 | JohnSmith | | 2 | John Doe | | 3 | Adam Smith | | 4 | CarolTaylor | +----+-----------------+ 4 rows in set (0.00 sec)
Following is the query to get a field value that does not contain empty spaces −
mysql> select *from DemoTable where StudentFullName NOT LIKE '% %';
This will produce the following output −
+----+-----------------+ | Id | StudentFullName | +----+-----------------+ | 1 | JohnSmith | | 4 | CarolTaylor | +----+-----------------+ 2 rows in set (0.18 sec)
