Exception Summary Exception Description CdsCommunicationException This exception is thrown when the client is unable to communicate with the remote system, such as data store or MTX "sidecar".CdsDataStoreException Exception thrown when an operation fails in the CdsDataStore.CdsException CdsLockTimeoutException Indicates that pessimistic locking conflict occurs when querying data from data source that does not result in transaction rollback.ConstraintViolationException Deprecated. EmptyResultException Thrown by the runtime whenResult.single()is executed and the result is empty.NonUniqueResultException Thrown by the runtime whenResult.single()is executed and the result contains more than one row.NotNullConstraintException Thrown to indicate that a NOT NULL constraint has been violated during an attempt to insert or update a CdsEntity.UniqueConstraintException Thrown by the data store, if a unique constraint is violated when executing an insert, upsert or update statement.
