Trying to save the first table fails when i put in that foreign key constraint. can't figure out why. both of the columns referenced in the constraint have the same type, size, etc: they only have a difference default value. one has a default value of null, the other is auto increment.

When i attempt to load the parsed binlog file (generated using mysqlbinlog 000004.binlog) with this command: it prints the following message: why it doesn't ignore foreign key constraints? does a line in the file parsed.binlog turn foreign key checks back on?.

Last sql error: error 'cannot add or update a child row: a foreign key constraint fails (`test db`.`column2`, constraint `column2` foreign key (`part`) references `part` (`part`) on delete cascade on)' on query. My problem was that the foreign key column and the referencing column were not of the same type or length. the foreign key column was smallint(5) unsigned. the referenced column was int(10) unsigned. once i made them both the same exact type, the foreign key creation worked perfectly. Disabling foreign key checks for the session, loading the data, and re enabling foreign key checks. that should prevent fk errors as you load the data. if you're using terminal, login to mysql using your credentials with the following command: set your mysql foreign key constraint checks to 0 using the next command:. The above exception (foreign key constraint failed) was the direct cause of the following exception: file "c:\users\tymot\appdata\local\programs\python\python37 32\lib\site packages\django\core\handlers\exception.py" in inner. And when i add the following foreign key: alter table `notification` add constraint `fk notification async task` foreign key (`async task id`) references `async task`(`idasync task`); i get: error 1005 (hy000): can't create table `my database`.`#sql 182 2d` (errno: 150 "foreign key constraint is incorrectly formed").
