How to add current date to an existing MySQL table?
To update an existing table, use UPDATE. With that, to set the current date, use the CURDATE() method −
update yourTableName set yourCoumnName=CURDATE();
Let us first create a table −
mysql> create table DemoTable -> ( -> DueDate datetime -> ); Query OK, 0 rows affected (0.58 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-01-10') ;
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('2019-03-31');
Query OK, 1 row affected (0.18 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+---------------------+ | DueDate | +---------------------+ | 2019-01-10 00:00:00 | | 2019-03-31 00:00:00 | +---------------------+ 2 rows in set (0.00 sec)
Following is the query to add current date to existing table −
mysql> update DemoTable set DueDate=CURDATE(); Query OK, 2 rows affected (0.13 sec) Rows matched: 2 Changed: 2 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable;
Output
This will produce the following output −
+---------------------+ | DueDate | +---------------------+ | 2019-06-22 00:00:00 | | 2019-06-22 00:00:00 | +---------------------+ 2 rows in set (0.00 sec)
