ERROR 1067 (42000): Invalid default value for 'created_at'

Question

When I tried to alter the table it showed the error:

ERROR 1067 (42000): Invalid default value for \'created_at\'

I googled for this error

Answer 1

I came across the same error while trying to install a third party database. I tried the solution proposed unsuccessfully i.e.
SET sql_mode = '';

Then I tried the command below which worked allowing the database to be installed
SET GLOBAL sql_mode = '';

Answer 2

Simply, before you run any statements put this in the first line:

SET sql_mode = '';

Answer 3

I had similar problem. Following solved it:

Change:

recollect_date TIMESTAMP DEFAULT 'CURRENT_TIMESTAMP',

to:

recollect_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

i.e. just remove the quotes around CURRENT_TIMESTAMP.

Hope this helps someone.

Answer 4

For Mysql5.7, login in mysql command line and run the command,

mysql> show variables like 'sql_mode' ;

It will show that NO_ZERO_IN_DATE,NO_ZERO_DATE in sql_mode.

Try to add a line below [mysqld] in your mysql conf file to remove the two option, mine(mysql 5.7 on Ubuntu 16) is /etc/mysql/mysql.conf.d/mysqld.cnf

Now restart mysql. It works!

Answer 5

In my case I have a file to import. So I simply added SET sql_mode = ''; at the beginning of the file and it works!

Answer 6

Just convert it by this line :

for the new table :

CREATE TABLE t1 (
  ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

---

for Existing Table:

Alter ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

---
