More likely "Row was not found to be deleted".

You have missing or wrong KeyLinks in your dataset object (TIB_Query, etc.)

It's an EIB_DatasetError that the dataset component raises when it cannot
determine the database row which is to receive the DELETE statement. Your
KeyLinks must uniquely identify a row.

This isn't the kind of error that you could catch and throw back to the
user - it's a programmer error.
