Counting voucher value total since the beginning of the month and year in MySQL

For this, use MySQL MONTH() and YEAR() methods. Let us first create a table −

mysql> create table DemoTable1562
   -> (
   -> VoucherValue int,
   -> RechargeDate date
   -> );
Query OK, 0 rows affected (1.40 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1562 values(149,'2019-10-21');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable1562 values(199,'2019-10-13');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable1562 values(399,'2018-10-13');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable1562 values(450,'2019-10-13');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1562;

This will produce the following output −

+--------------+--------------+
| VoucherValue | RechargeDate |
+--------------+--------------+
|          149 | 2019-10-21   |
|          199 | 2019-10-13   |
|          399 | 2018-10-13   |
|          450 | 2019-10-13   |
+--------------+--------------+
4 rows in set (0.00 sec)

The current date is as follows −

mysql> select curdate();
+------------+
| curdate()  |
+------------+
| 2019-10-13 |
+------------+
1 row in set (0.00 sec)

Here is the query to count voucher value total since the beginning of month and year.

mysql> select sum(VoucherValue) from DemoTable1562
   -> where month(RechargeDate)=month(curdate())
   -> and year(RechargeDate)=year(curdate());

This will produce the following output −

+-------------------+
| sum(VoucherValue) |
+-------------------+
|               798 |
+-------------------+
1 row in set (0.00 sec)
