How to cast DATETIME as a DATE in MySQL?
To cast DATETIME as a DATE in MySQL, use the CAST() function. 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 −
mysql> create table ConvertDatetimeToDate −> ( −> YourDatetime datetime −> ); Query OK, 0 rows affected (0.95 sec)
Inserting datetime into the table with the help of insert command. The query is as follows −
mysql> insert into ConvertDatetimeToDate values(date_add(now(),interval 1 day)); Query OK, 1 row affected (0.17 sec) mysql> insert into ConvertDatetimeToDate values(date_add(now(),interval -1 day)); Query OK, 1 row affected (0.15 sec) mysql> insert into ConvertDatetimeToDate values(date_add(now(),interval 1 year)); Query OK, 1 row affected (0.10 sec) mysql> insert into ConvertDatetimeToDate values(date_add(now(),interval -1 year)); Query OK, 1 row affected (0.16 sec)
Display all the records inserted above. The query is as follows −
mysql> select *from ConvertDatetimeToDate;
The following is the output −
+---------------------+ | YourDatetime | +---------------------+ | 2018-11-28 16:12:50 | | 2018-11-26 16:13:00 | | 2019-11-27 16:13:13 | | 2017-11-27 16:13:24 | +---------------------+ 4 rows in set (0.00 sec)
Now you can apply the above syntax to cast datetime to date. The query is as follows −
mysql> select cast(YourDatetime as Date) as OnlyDateDemo from ConvertDatetimeToDate;
The following is the output −
+--------------+ | OnlyDateDemo | +--------------+ | 2018-11-28 | | 2018-11-26 | | 2019-11-27 | | 2017-11-27 | +--------------+ 4 rows in set (0.00 sec)
