Most of the time, when I create a foreign key, the covering index is automatically named and generated, and the table that gets the foreign key also gets an index with a name beginning with "fki". But sometimes, when I try to save the FK, I get an error message asking me to supply a name for the covering index. Why do I sometimes have to supply a name and sometimes not? What can I do to ensure that the covering index is automatically named? Thank you. RobR
