Log Message:
propagated changes of Saturday Jan 30 2010 - Sunday Jan 31 2010
from the Feb2010 branch to the development trunk
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2010/01/30 - nielsnes: src/server/sql_statement.mx,1.197.2.1
the select statements didn't get pushed through the diffs and unions anymore.
Reason we added lots of 'st_alias'es around statements during the development
of the relational version. These st_aliases are now handled correctly fixing
the push down.
