Let us first create a table −
mysql> create table DemoTable1822 ( Amount int, DueDate date ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1822 values(1000,'2019-10-11'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1822 values(500,'2019-11-30'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1822 values(700,'2018-11-30'); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1822;
This will produce the following output −
+--------+------------+ | Amount | DueDate | +--------+------------+ | 1000 | 2019-10-11 | | 500 | 2019-11-30 | | 700 | 2018-11-30 | +--------+------------+ 3 rows in set (0.00 sec)
Here is the query to update database record on a specific date −
mysql> update DemoTable1822 set Amount=5000 where DueDate=curdate(); Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1822;
This will produce the following output −
+--------+------------+ | Amount | DueDate | +--------+------------+ | 1000 | 2019-10-11 | | 5000 | 2019-11-30 | | 700 | 2018-11-30 | +--------+------------+ 3 rows in set (0.00 sec)
