i have a table A and i want to update the creation time of this table. I understand i cant simple update ( using update query) as it is not any table.

Is there any way i can update it.

for example creation time is '2015-07-03 12:03:33' to '2015-06-03 12:03:33'

  • What is the storage engine of table A ? MyISAM or InnoDB ? – RolandoMySQLDBA Jun 6 '16 at 20:43
  • Storage engine of table A is Innodb – simplifiedDB Jun 8 '16 at 12:31
  • I don't think it is possible to change the creation time of an InnoDB table. – Rick James Jun 23 '16 at 5:04

Information_Schema are views and read-only. Yo can not update meta data about tables, only by modifying actual table with ALTER TABLE. If you do an ALTER TABLE you will have current timestamp in meta data.

INFORMATION_SCHEMA is a database within each MySQL instance, the place that stores information about all the other databases that the MySQL server maintains. The INFORMATION_SCHEMA database contains several read-only tables. They are actually views, not base tables, so there are no files associated with them, and you cannot set triggers on them. Also, there is no database directory with that name.

Although you can select INFORMATION_SCHEMA as the default database with a USE statement, you can only read the contents of tables, not perform INSERT, UPDATE, or DELETE operations on them.

What's the exact reason you need to change meta data?

  • This wasn't enough for me. I also had to run OPTIMIZE TABLE – Urbycoz Nov 5 '20 at 13:57
