Syntax error MySQL query to get result by month and year based on condition?

MySQL query to get result by month and year based on condition?

You need to use OR condition along with WHERE clause. Let us first create a table −

mysql> create table DemoTable
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   MonthNumber int,
   YearNumber int
   );
Query OK, 0 rows affected (0.22 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(MonthNumber,YearNumber) values(11,2018);
Query OK, 1 row affected (0.10 sec)

mysql> insert into DemoTable(MonthNumber,YearNumber) values(3,2019);
Query OK, 1 row affected (0.12 sec)

mysql> insert into DemoTable(MonthNumber,YearNumber) values(12,2018);
Query OK, 1 row affected (0.08 sec)

mysql> insert into DemoTable(MonthNumber,YearNumber) values(1,2019);
Query OK, 1 row affected (0.06 sec)

mysql> insert into DemoTable(MonthNumber,YearNumber) values(12,2019);
Query OK, 1 row affected (0.10 sec)

mysql> insert into DemoTable(MonthNumber,YearNumber) values(6,2018);
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 −

+----+-------------+------------+
| Id | MonthNumber | YearNumber |
+----+-------------+------------+
| 1  | 11          | 2018       |
| 2  | 3           | 2019       |
| 3  | 12          | 2018       |
| 4  | 1           | 2019       |
| 5  | 12          | 2019       |
| 6  | 6           | 2018       |
+----+-------------+------------+
6 rows in set (0.00 sec)

Following is the query to get result by month and year −

mysql> select Id,MonthNumber,YearNumber from DemoTable
where (MonthNumber >= 11 AND YearNumber = 2019)
OR
(MonthNumber <=11 AND YearNumber = 2018);

This will produce the following output −

+----+-------------+------------+
| Id | MonthNumber | YearNumber |
+----+-------------+------------+
| 1  | 11          | 2018       |
| 5  | 12          | 2019       |
| 6  | 6           | 2018       |
+----+-------------+------------+
3 rows in set (0.00 sec)
