Update MySQL table column by matching date using date() function?
Following is the syntax to match date with date() function and updating a column −
update yourTableName set yourColumnName=yourValue where date(yourColumnName)=curdate();
Let us first create a table −
mysql> create table DemoTable1816 ( Name varchar(20), JoiningDate datetime ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1816 values('Chris','2019-11-29 12:34:50');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1816 values('David','2019-11-30 11:00:00');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1816 values('Mike','2018-11-30 10:20:30');
Query OK, 1 row affected (0.00 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1816;
This will produce the following output −
+-------+---------------------+ | Name | JoiningDate | +-------+---------------------+ | Chris | 2019-11-29 12:34:50 | | David | 2019-11-30 11:00:00 | | Mike | 2018-11-30 10:20:30 | +-------+---------------------+ 3 rows in set (0.00 sec)
Here is the query to update a column by matching date −
mysql> update DemoTable1816 set Name='Robert' where date(JoiningDate)=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 DemoTable1816;
This will produce the following output −
+--------+---------------------+ | Name | JoiningDate | +--------+---------------------+ | Chris | 2019-11-29 12:34:50 | | Robert | 2019-11-30 11:00:00 | | Mike | 2018-11-30 10:20:30 | +--------+---------------------+ 3 rows in set (0.00 sec)
