Hello,
in a table A there is a primary key, one column named ID. The second table B
uses a single Field named ID_TableA, it references to the Table A (foreign
key) and this field is the primary key too. (1 to 1 relation). Now I have
two indexes for one Table-Column. Is this an problem?
Thank you
Best regards.
