According to this documentation  starting in MySQL 8 0 13  you will be able to specify   CREATE TABLE INVOICE      INVOICEDATE DATE DEFAULT  CURRENT DATE      Unfortunately  as of today  that version is not yet released   You can check here for the latest updates

declare your date column as NOT NULL  but without a default   Then add this trigger   USE  ddb   DELIMITER    CREATE TRIGGER  default date  BEFORE INSERT ON  dtable  FOR EACH ROW if   isnull new query date    then  set new query date curdate    end if     delimiter

As the other answer correctly notes  you cannot use dynamic functions as a default value  You could use TIMESTAMP with the CURRENT TIMESTAMP attribute  but this is not always possible  for example if you want to keep both a creation and updated timestamp  and you d need the only allowed TIMESTAMP column for the second   In this case  use a trigger instead

It doesn t work because it s not supported     The DEFAULT clause specifies a default value for a column  With one exception  the default value must be a constant  it cannot be a function or an expression  This means  for example  that you cannot set the default for a date column to be the value of a function such as NOW   or CURRENT DATE  The exception is that you can specify CURRENT TIMESTAMP as the default for a TIMESTAMP column   http   dev mysql com doc refman 5 5 en create-table html

User · Answer

Currently from MySQL 8 you can set the following to a DATE column   In MySQL Workbench  in the Default field next to the column  write   curdate     If you put just curdate   it will fail  You need the extra   and   at the beginning and end
