      Description

      Can't define CURRENT_TIMESTAMP as default value for added column

      Example:

       
      CREATE TABLE `table2` (
        `i1` INT(10) UNSIGNED NOT NULL
      ) ENGINE=INNODB DEFAULT CHARSET=latin1;
       
      INSERT INTO table2 (i1) VALUES (1), (2), (3), (4), (5);
       
      ALTER TABLE  `table2` ADD `d1` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP;
       
      SELECT * FROM table2;

          i1                   d1  
      ------  ---------------------
           1    0000-00-00 00:00:00
           2    0000-00-00 00:00:00
           3    0000-00-00 00:00:00
           4    0000-00-00 00:00:00
           5    0000-00-00 00:00:00

      Expected that d1 filled with CURRENT_TIMESTAMP values instead '0000-00-00 00:00:00' because '0000-00-00 00:00:00' is incorrect for this filed value.

      I can prove it:

      INSERT INTO table2 (i1, d1) VALUES (6, '0000-00-00 00:00:00')
      -- return
      Error Code: 1292
      Incorrect datetime value: '0000-00-00 00:00:00' for column 'd1' at row 1

      OR

      CREATE TABLE `table1` (
        `i1` INT(10) UNSIGNED NOT NULL,
        PRIMARY KEY (`i1`)
      ) ENGINE=INNODB DEFAULT CHARSET=latin1;
       
      INSERT INTO table1 (i1) VALUES (1), (2), (3), (4), (5);
       
      ALTER TABLE `test`.`table2`  
        ADD FOREIGN KEY (`i1`) REFERENCES `table1`(`i1`);
      -- return
      Error Code: 1292
      Incorrect datetime value: '0000-00-00' for column 'd1' at row 1
