Is there an open source SQL Server DB compare tool? [closed]

Answer 1

Anyone try xSQL Bundle (xSQL Data Compare and xSQL Object Compare)? Our place only uses for DB diffs, no syncs, so can't say for syncing but the diff and reports are not bad.

Also, OpenDBDiff has a spin off, not sure which is better - http://code.google.com/p/sql-dbdiff/

Anyone know if any of the free/open source DB diff tools mentioned here offer scriptable / command line interface to automate the diffs and synching?

I looked into xSQL tools, they offer command line access but unfortunately, no scriptable command to export diff results to (report) file.

Answer 2

We have both SQL Delta and SQL Compare. Each has strengths, but each also have weaknesses that make them quite a pain.

SQL Delta will miss some triggers in its comparison, and it will take actions not found in the action list, and it will sometimes take actions you did not want it to take. That was discovered at quite a cost in time.

SQL Compare will catch the triggers, but they are embedded within the table listings. On a large database, that means going through each table and sifting them out. Something the tool should have isolated for us. Again, quite a cost in time.

Answer 3

I think that Open DBiff does a good job. It's simple and I works with SQL Server 2005/2008.

But only generate the change script. Nothing more and nothing less.

It's not open source, but is free (as in beer): Sql Effects Accord (aka Clarity) Community Edition

Answer 5

Hmm, none that I know of. You can always retrieve the definitions as SQL and then run a diff tool on them, but it's a bit of a pain in the rear.

Probably the best solution for this is using some kind of "Migrations" tool, so you can keep your database definitions together with your code, and version them, etc.

Update

On Sourceforge I found Whiz SQL Structure Compare with this description: Whiz is a database diff utility which will be useful to find difference between two MS-SQL Server databases. It also able to generate SQL script to update the changes from one database to another database.

However, I've been unsuccessful in getting it to work so far...
