Get all results using WHERE clause in MySQL?

MySQLMySQLi Database

To get all results using WHERE clause, you can use LIKE operator. We can also get all the results using “Select * from table_name”.

Let us first create a table:

mysql> create table DemoTable
(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   Name varchar(20)
);
Query OK, 0 rows affected (0.56 sec)

Following is the query to insert records in the table using insert command:

mysql> insert into DemoTable(Name) values('Larry');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable(Name) values('John');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable(Name) values('Bob');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable(Name) values('Carol');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(Name) values('Chris');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(Name) values('David');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(Name) values('Mike');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable(Name) values('Sam');
Query OK, 1 row affected (0.11 sec)

Following is the query to display records from the table using select command:

mysql> select *from DemoTable;

This will produce the following output:

+----+-------+
| Id | Name  |
+----+-------+
| 1  | Larry |
| 2  | John  |
| 3  | Bob   |
| 4  | Carol |
| 5  | Chris |
| 6 | David  |
| 7 | Mike   |
| 8 | Sam    | 
+----+-------+
8 rows in set (0.00 sec)

Query to get all results using WHERE clause:

mysql> select *from DemoTable where Name like '%';

This will produce the following output:

+----+-------+
| Id | Name  |
+----+-------+
|  1 | Larry |
|  2 | John  |
|  3 | Bob   |
|  4 | Carol |
|  5 | Chris |
|  6 | David |
|  7 | Mike  |
|  8 | Sam   |
+----+-------+
8 rows in set (0.00 sec)
