Compare Schema shows differences between schemas that are supposed to be the same. (4291668)

Compare Schema shows differences between schemas that are supposed to be the same.

When running DBA | Compare Schema, Toad reports differences found between two identical scripts. The script that is used in the compare schema feature is identical to the script that is viewable in the Schema Browser under the schema�s Script tab. Check this for differences.

Example 1: Differs by ungrantable privileges

A script may have something like:

GRANT INSERT, UPDATE ON A_SYSTEM TO A_USER;

on one end

and

GRANT INSERT ON A_SYSTEM TO A_USER;
GRANT UPDATE ON A_SYSTEM TO A_USER;

on another. These are basically the same, but Toad will consider them as differences.

Example 2: Differ by package body

The scripts look exactly the same. Go to Schema Browser | Procs() tab | Packages and select the package bodies Script tab and save the package body scripts from both schemas to a text file. Then open both for File Compare under File menu | File Compare. Check for any character differences. Even whitespaces make a difference.
