Working with dates before 1970 in MySQL?
You need to use date type to work with date before 1970 because date stores value from 1000 to 9999. A date type can be used when you need to work with date part only not for time purpose.
MySQL gives the data in the following format. The format is as follows −
‘YYYY-MM-DD’
The starting date range is as follows −
1000-01-01
The ending date range is as follows −
9999-12-31
To understand what we discussed above, let us create two tables. The query to create first table is as follows −
mysql> create table DateDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> DateBefore1970 date -> ); Query OK, 0 rows affected (0.71 sec)
Now you can insert some records in the table using insert command. Whenever you use beyond the ending date '9999-12-31', you will get a date ‘0000-00-00’.
Let us insert a record which is greater than '9999-12-31'. The query is as follows −
mysql> insert into DateDemo(DateBefore1970) values('1000-10-20');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DateDemo(DateBefore1970) values('1940-12-31');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DateDemo(DateBefore1970) values('1500-01-25');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DateDemo(DateBefore1970) values('1900-04-14');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DateDemo(DateBefore1970) values('1710-11-15');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DateDemo(DateBefore1970) values('9999-12-31');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DateDemo(DateBefore1970) values('10000-12-31');
Query OK, 1 row affected, 1 warning (0.11 sec)Now you can display all records from the table using select statement. The query is as follows −
mysql> select *from DateDemo;
The following is the output −
+----+----------------+ | Id | DateBefore1970 | +----+----------------+ | 1 | 1000-10-20 | | 2 | 1940-12-31 | | 3 | 1500-01-25 | | 4 | 1900-04-14 | | 5 | 1710-11-15 | | 6 | 9999-12-31 | | 7 | 0000-00-00 | +----+----------------+ 7 rows in set (0.00 sec)
