I have a very easy table (id, name, parent) that represents a tree. I want to use dbunit while testing this table, so I created a simple dataset for 2 nodes (yaml instead of xml for readability):
node: - id: 1 name: default parent: null - id: 2 name: default-child parent: 1
This gets inserted all right, but when trying to clean the table (I m using DatabaseOperation.CLEAN_INSERT) it causes a constraint violation:
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (node, CONSTRAINT FK_NODE.PARENT_TO_NODE.ID FOREIGN KEY (parent) REFERENCES node (id))
