Group By Names and Display Count in MySQL

Use GROUP BY with the COUNT() method. Group the names with GROUP BY and count using the COUNT() method. Let us first create a table −

mysql> create table DemoTable
(
   Name varchar(30)
);
Query OK, 0 rows affected (0.63 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.12 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+--------+
| Name   |
+--------+
| Chris  |
| Robert |
| Mike   |
| Robert |
| Mike   |
| David  |
+--------+
6 rows in set (0.00 sec)

Following is the query to group by names and display the count −

mysql> select Name,count(Name) as NumberOfRowsPerName from DemoTable group by Name;

This will produce the following output −

+--------+---------------------+
| Name   | NumberOfRowsPerName |
+--------+---------------------+
| Chris  |                   1 |
| Robert |                   2 |
| Mike   |                   2 |
| David  |                   1 |
+--------+---------------------+
