User's Guide Part VI. SQL Anywhere Reference Chapter 44. SQL Anywhere Database Error MessagesThe SQL Anywhere engine has many internal checks that have been designed to detect possible database corruption as soon as possible. If the database engine prints an Assertion Failed message, you should not continue to use it before attempting to determine the cause. You should record the assertion number displayed on the screen and report the error to SQL Anywhere technical support.
The DBVALID utility is useful for determining if your database file is corrupt. You may find it necessary to reconstruct your data from backups and transaction logs (see the chapter "Backup and Recovery").
