Resolved that, finally.
When MySQL performs UPDATE query, it returns numbers of affected rows 
only (and only) if record has been actually changed. I was sure, I run 
the query which updates record with different values.

When I ran it in MySQL prompt I noticed:

0 rows affected
Rows matched: 1

So libgda does correct thing returning 0 in my case.
But some hint is required IMO, anyway.
One doesn't know if 0 means "no matching row" or "row is the same".

I propose to add MATCHED_ROW if possible.
