Syntax error Is it possible to make an insert or an update in the same MySQL query?

Is it possible to make an insert or an update in the same MySQL query?

Yes, use ON DUPLICATE KEY UPDATE. Let us first create a table −

mysql> create table DemoTable(Id int NOT NULL PRIMARY KEY, Number int);
Query OK, 0 rows affected (0.83 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values(1,190) ON DUPLICATE KEY UPDATE Number=Number+10;
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values(2,130) ON DUPLICATE KEY UPDATE Number=Number+10;
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values(1,190) ON DUPLICATE KEY UPDATE Number=Number+10;
Query OK, 2 rows affected (0.14 sec)
mysql> insert into DemoTable values(2,130) ON DUPLICATE KEY UPDATE Number=Number+10;
Query OK, 2 rows affected (0.17 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output. We have inserted and updated records in the same query −

+----+--------+
| Id | Number |
+----+--------+
| 1  | 200    |
| 2  | 140    |
+----+--------+
2 rows in set (0.00 sec)
