If a cursor contains joins, he'd like to clarify which table (and 
columns) should be updatable in that cursor. The SQL specifications 
specifies the "updatable joins and unions" feature, but its description 
is far from being clear and I fail to see how it correlates with <column 
name> in the FOR UPDATE clause...
