I'm running MySql Server 5.7.11 and this sentence:
updated datetime NOT NULL DEFAULT '0000-00-00 00:00:00'
ERROR 1067 (42000): Invalid default value for 'updated'
updated datetime NOT NULL DEFAULT '1000-01-01 00:00:00'
The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. The supported range is '1000-01-01' to '9999-12-31'.
Invalid DATE, DATETIME, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00' or '0000-00-00 00:00:00').
The error is because of the sql mode which can be strict mode as per latest MYSQL 5.7 documentation
Strict mode affects whether the server permits '0000-00-00' as a valid date: If strict mode is not enabled, '0000-00-00' is permitted and inserts produce no warning. If strict mode is enabled, '0000-00-00' is not permitted and inserts produce an error, unless IGNORE is given as well. For INSERT IGNORE and UPDATE IGNORE, '0000-00-00' is permitted and inserts produce a warning.
To Check MYSQL mode
SELECT @@GLOBAL.sql_mode global, @@SESSION.sql_mode session
Disabling STRICT_TRANS_TABLES mode
However to allow the format
0000-00-00 00:00:00you have to disable STRICT_TRANS_TABLES mode in mysql config file or by command
SET sql_mode = '';
if above is not working than go to
/etc/mysql/my.cnf (as per ubuntu) and comment out
However strict mode is not enabled by default in MYSQL 5.6. Hence it does not produce the error as per MYSQL 6 documentation which says
MySQL permits you to store a “zero” value of '0000-00-00' as a “dummy date.” This is in some cases more convenient than using NULL values, and uses less data and index space. To disallow '0000-00-00', enable the NO_ZERO_DATE SQL mode.
Regarding the bug matter as said by @Dylan-Su:
I don't think this is the bug it the way MYSQL is evolved over the time due to which some things are changed based on further improvement of the product.
However I have another related bug report regarding the
Another Useful note [see Automatic Initialization and Updating for TIMESTAMP and DATETIME]
As of MySQL 5.6.5, TIMESTAMP and DATETIME columns can be automatically initializated and updated to the current date and time (that is, the current timestamp). Before 5.6.5, this is true only for TIMESTAMP, and for at most one TIMESTAMP column per table. The following notes first describe automatic initialization and updating for MySQL 5.6.5 and up, then the differences for versions preceding 5.6.5.
