 To review two versions of
a schema object, use the side-by-side comparison panel to the right
of the schema view. It opens when you double-click or press Enter
on any single schema item. You can also click the "Compare" button
on the schema tree's toolbar.
Note that whether two
objects are the same or different (and thus need be synchronized)
is determined solely by the main schema comparison algorithm and
indicated by the color markup in the schema tree. The
side-by-side comparison uses a separate plain-text comparison
algorithm and its only purpose is to show you the changes in SQL
definitions. There could be situations when the side-by-side view
shows differences which are not important and are ignored by the
actual schema comparison. When in doubt, rely on the schema
tree.
Also note that the
side-by-side view uses its own set of colors, not necessarily
synchronized with those used in the schema tree.
Comparison
options. The "Tools/Compare
Options" button in the main menu invokes the Options dialog,
open on the page where you
can specify the appearance of the side-by-side panel.
Weighted
phrases. The list of
"line weights", which the side-by-side algorithm uses to make
certain lines (such as "create proc") to stick to each other, has
been moved from the "Compare Options" dialog to an initialization
file ASQLDIFF.LWS. There is normally no reason to change this
list, but if you do need to change it, edit it as a regular text
file (there are more details inside the file itself).
