診断

Check if the foreign key exist in the MySQL database:

USE INFORMATION_SCHEMA;
SELECT * FROM KEY_COLUMN_USAGE WHERE CONSTRAINT_NAME='FK1C588BB9C50DAE44';

The constraint might be different depending on the version. Check the error for the constraint name.

原因

Restoring/upgrading Fisheye for a multiple time in the same database might have deleted the foreign key previously.

回避策

  1. Restore the database to the state before the restore/upgrade.
  2. Check if the foreign key exist in the database according to the Diagnosis section.
  3. Check the database schema of the Fisheye/Crucible before restore/upgrade at FISHEYE_HOME/sql/MYSQL/schema/constraints_*.sql.

    Refer to the largest number of the file.

  4. Add back the specific constraint to the database according to the file.
  5. Restore/upgrade Fisheye/Crucible again

ソリューション

  1. Restore the database to the state before the restore/upgrade.
  2. Create a backup of the database
  3. Create a new database
  4. Restore the backup into the new database
