Any way to do a differential on two versions of a table?

Levi Sauerbrei
$organization

I'm trying to figure out why the numbers in one of our long standing reports shifted unexpectedly last Friday.  So far, nothing  we can find points us to the culprit.

Our test system is holding the copy of the database from the day before the problem popped up so in theory I should be able to compare some of the tables from the test system to their counterparts in the live system and come up with some likely suspects.

So the question is this.  Is there a straightforward way to do a differential on two tables that are structurally the same? (other than writing a bunch of SQL from scratch)  I'd like to see both changes in existing records and any rows that were added.  I can get the additional rows pretty easily through the primary keys, but seeing what changes may have happened to existing records might be trickier.

    To answer my own question a bit.  It looks like the EXCEPT and INTERSECT commands in SQL will do alot of this.  I'd still be interested in something that is a little more visual. Something like WinDiff, but for the database.

    There’s a commercial tool from RedGate that says it does this – I haven’t used it. Might be others.

    Redgate is awesome you can get the trial version for your purposes. Then purchase it later if allowable by your business. We used the trial version here, when we get money in the budget we will be getting it!
