如何获取 MySQL 表的创建日期？

To get the creation date of a MySQL table, use information_schema. The syntax is as follows -

SELECT create_time FROM INFORMATION_SCHEMA.TABLES
   WHERE table_schema = &#39;yourDatabaseName&rsquo;
   AND table_name = &#39;yourTableName&#39;;

Copy after login

Apply the above syntax to your database and table names. Here I use the database "business" and the table name is "student". The query is as follows -

mysql> SELECT create_time FROM INFORMATION_SCHEMA.TABLES
   -> WHERE table_schema = &#39;business&#39;
   -> AND table_name = &#39;student&#39;;

Copy after login

The following is the output showing the table creation time -

+---------------------+
| CREATE_TIME         |
+---------------------+
| 2018-10-01 12:26:57 |
+---------------------+
1 row in set (0.12 sec)

Copy after login

Let us see another example and create a table from scratch.

mysql> create table DateAsStringDemo
   -> (
   -> YourDateTime datetime
   -> );
Query OK, 0 rows affected (0.57 sec)

Copy after login

I have just created a table and my current date time is as follows -

mysql> select now();

Copy after login

Below is the output -

+---------------------+
| now()               |
+---------------------+
| 2018-11-26 18:12:29 |
+---------------------+
1 row in set (0.00 sec)

Copy after login

Now you can check the creation time of the above table, it The date 2018-11-26 will be given.

The query is as follows -

mysql> SELECT create_time FROM INFORMATION_SCHEMA.TABLES
   -> WHERE table_schema = &#39;test&#39;
   -> AND table_name = &#39;DateAsStringDemo&#39;;

Copy after login

The following is the output -

+---------------------+
| CREATE_TIME         |
+---------------------+
| 2018-11-26 18:01:44 |
+---------------------+
1 row in set (0.00 sec)

Copy after login
