It's good for debugging. Otherwise, I don't know which row has this problem. mysqlimport: Error: 1452, Cannot add or update a child row: a foreign key constraint fails (`bwordDS`.`Category_Term`, CONSTRAINT `FK_qn1crq26sr0hqm5q2p7nfvdu1` FOREIGN KEY (`categories_id`) REFERENCES `Category` (`id`)), when using table: Category_Term mysql mysqlimport share|improve this http://stackoverflow.com/questions/36276053/mysqlimport-error-message-1452 question asked Mar 29 at 5:22 user697911 1,21421525 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote First check if Category table exist where you are trying to import this data. if Category table exists then need to check that all category_id in this table should exist in Category table as id. Better option is to import first category table and then this table. In generic first all parent tables data should import then child tables. A dirty way is as per below which is not recommended- set foreign_key_checks=0; import data here; set foreign_key_checks=1; Just to know which row is creating problem- Below query will provide you problematic rows. SELECT a.category_id FROM Category_Term a LEFT JOIN Category b ON a.category_id=b.id WHERE b.id IS NULL; Note: Assuming category_id in category_term and id in category tables will be indexed. share|improve this answer edited Mar 29 at 5:35 answered Mar 29 at 5:29 Zafar Malik 5,1901624 "check that all category_id in this table should exist in Category table as id.". I want to do this too. It's a large table. I have to write separate code to do this? It would be nice if mysqlimp
