 Here you can specify path
to the "column configuration file"
used by DataDiff to assign default roles to columns in a new
comparison. You can change the "Filter file" field with the
"Choose" ("Browse...") and "Clear" buttons. The rest of the
stuff on this panel is a kind of editor for changing the contents
of this file, so what you see there doesn't get saved
automatically.
The
built-in editor. The options dialog
provides a very simple way to edit the column configuration file
without using an external editor. Whenever you choose a filename,
the file is scanned and all [Ignore], [Compare] and [Keys] rules
are displayed in the 3 columns. You can then edit them and save
them back to file. Please note that the contents of these three
edit boxes are not automatically saved to the file nor cached in
memory. Once you close the Options dialog, the file name is
remembered, but any changes you might have done to the rules will
be lost, unless you have explicitly saved them.
Note that if your
configuration file has been created manually and contains repeated
sections, or the order of sections is important (like in the
example shown above), you must continue using an external editor
and should
not use the Save button, as it will overwrite
your design, writing all the rules into 3 sections in a predefined
order.
