Dag H. Wanvik commented on DERBY-6623:
--------------------------------------
One could argue that it fragile to use the toString method in this way. I did
it to avoid having to extend the IndexDescriptor interface with another method
with an ordering value. But we could consider
adding some such:
IndexDescriptor#getFirstBaseColumn
and order on that. Opinions?
