Sum Varchar Column and Display Count in MySQL

For this, use GROUP BY along with COUNT(*). Let us first create a table −

mysql> create table DemoTable
(
   EmployeeId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   EmployeeGender varchar(40)
);
Query OK, 0 rows affected (0.48 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(EmployeeGender) values('MALE');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(EmployeeGender) values('FEMALE');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable(EmployeeGender) values('FEMALE');
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable(EmployeeGender) values('FEMALE');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable(EmployeeGender) values('MALE');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable(EmployeeGender) values('MALE');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable(EmployeeGender) values('MALE');
Query OK, 1 row affected (0.07 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+------------+----------------+
| EmployeeId | EmployeeGender |
+------------+----------------+
|          1 | MALE           |
|          2 | FEMALE         |
|          3 | FEMALE         |
|          4 | FEMALE         |  
|          5 | MALE           |
|          6 | MALE           |
|          7 | MALE           |
+------------+----------------+
7 rows in set (0.00 sec)

Following is the query to sum the varchar column. This will sum the MALE and FEMALE column values and count would be displayed −

mysql> select EmployeeGender,count(*) from DemoTable
   group by EmployeeGender;

This will produce the following output −

+----------------+----------+
| EmployeeGender | count(*) |
+----------------+----------+
| MALE           |        4 |
| FEMALE         |        3 |
+----------------+----------+
2 rows in set (0.00 sec)
