candidate_keys lists nullable unique indexes #6

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
the current implementation of candidate_keys view lists nullable unique 
indexes. These are not true candidate keys, because the occurrence of null 
values could make it impossible to uniquely identify a row.

This is fixed in revision 71 (not yet released)
I have made some changes and additions to views, plus a new view. Please read 
revision comment.

In short: I do suggest unique keys which has nullable keys, but notifies the 
user about that.
