MySQL Query to convert from datetime to date?

MySQLMySQLi Database

You can use CAST() function from MySQL to achieve this. The syntax is as follows −

SELECT CAST(yourColumnName as Date) as anyVariableName from yourTableName;

To understand the above syntax, let us first create a table. The query to create a table is as follows −

mysql> create table ConvertDateTimeToDate
-> (
-> ArrivalDatetime datetime
-> );
Query OK, 0 rows affected (0.37 sec)

Insert the datetime in the table using insert command. The query is as follows −

mysql> insert into ConvertDateTimeToDate values(date_add(now(),interval -1 year));
Query OK, 1 row affected (0.19 sec)

mysql> insert into ConvertDateTimeToDate values('2017-11-21 13:10:20');
Query OK, 1 row affected (0.14 sec)

mysql> insert into ConvertDateTimeToDate values('2016-05-24 21:11:24');
Query OK, 1 row affected (0.26 sec)

mysql> insert into ConvertDateTimeToDate values('2012-04-30 04:05:50');
Query OK, 1 row affected (0.13 sec)

Let us now display all records from the table using select command. The query is as follows.

mysql> select *from ConvertDateTimeToDate;

The following is the output.

+---------------------+
| ArrivalDatetime     |
+---------------------+
| 2017-12-27 10:05:21 |
| 2017-11-21 13:10:20 |
| 2016-05-24 21:11:24 |
| 2012-04-30 04:05:50 |
+---------------------+
4 rows in set (0.00 sec)
