For this, you can use the DATE() function. Let us first create a table −
mysql> create table DemoTable ( Number int ); Query OK, 0 rows affected (0.48 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(20190108); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values(20161231); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(20170411); Query OK, 1 row affected (0.09 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----------+ | Number | +----------+ | 20190108 | | 20161231 | | 20170411 | +----------+ 3 rows in set (0.00 sec)
Following is the query to convert yyyymmdd in int type to date −
mysql> select date(Number) from DemoTable;
This will produce the following output −
+--------------+ | date(Number) | +--------------+ | 2019-01-08 | | 2016-12-31 | | 2017-04-11 | +--------------+ 3 rows in set (0.00 sec)
