Database Migration to MySQL Fails with 'com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException'
症状
Database migration from HSQLDB to MySQL fails with the following exception reported in the fisheye-debug-<date>.log:
2012-08-21 15:18:22,357 ERROR [ThreadPool1 ] fisheye.app DBEditHelper-doGet - Database migration failed: com.cenqua.crucible.hibernate.CruDBException: Problem with constraints script /Users/ganand/fecru_installs/fecru-2.8.0/sql/MYSQL/schema/constraints_78.sql

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails (`fisheye`.`#sql-b2_b`, CONSTRAINT `FK4498CEEEA697BC70` FOREIGN KEY (`cru_user_id`) REFERENCES `cru_user` (`cru_user_id`))
原因
The Fisheye/Crucible database has orphaned records, which is preventing the respective tables to be updated during database migration. This is normally experienced when migrated from the embedded HSQLDB.
ソリューション
Ensure a complete backup of Fisheye/Crucible database has been taken prior to proceeding further. This will help revert the changes if the following steps fail.
Shut down the application and run the following queries on Fisheye/Crucible database:
select * from cru_user_profile where CRU_user_id not in (select CRU_user_id from CRU_user);
delete from cru_user_profile where CRU_user_id not in (select CRU_user_id from CRU_user);
Then restart Fisheye and attempt the database migration again on a fresh MySQL database.
