I got a stupid problem with SQL that I can't fix.
ALTER TABLE `news`
ADD `dateAdded` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP AUTO_INCREMENT ,
ADD PRIMARY KEY ( `dateAdded` )
Error:
(#1067)Invalid default value for 'dateAdded'
Can somebody help me?
Answer
CURRENT_TIMESTAMP
is only acceptable on TIMESTAMP
fields. DATETIME
fields must be left either with a null default value, or no default value at all - default values must be a constant value, not the result of an expression.
relevant docs: http://dev.mysql.com/doc/refman/5.0/en/data-type-defaults.html
You can work around this by setting a post-insert trigger on the table to fill in a "now" value on any new records.
