How to get the count of a specific value in a column with MySQL?

Let us first create a table −

mysql> create table DemoTable
   (
      Id int,
      Name varchar(100)
   );
Query OK, 0 rows affected (1.40 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values(100,'John');
Query OK, 1 row affected (0.44 sec)
mysql> insert into DemoTable values(101,'Chris');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values(102,'Chris');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values(103,'Chris');
Query OK, 1 row affected (1.05 sec)
mysql> insert into DemoTable values(104,'David');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values(105,'Chris');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values(106,'Carol');
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable values(107,'Bob');
Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+------+-------+
| Id   | Name  |
+------+-------+
| 100  | John  |
| 101  | Chris |
| 102  | Chris |
| 103  | Chris |
| 104  | David |
| 105  | Chris |
| 106  | Carol |
| 107  | Bob   |
+------+-------+
8 rows in set (0.00 sec)

Following is the query to get the count of a specific value in a column i.e. ‘Chris’ here −

mysql> select count(*) from DemoTable where Name='Chris';

This will produce the following output −

+----------+
| count(*) |
+----------+
| 4        |
+----------+
1 row in set (0.00 sec)
