Red-Gate has very interesting in beta software (Sql Source Control) that is installing inside SSMS and can save schema iterations through commit button. I need the same feature for postgresql, the only way i found similar to this - is log_statement = ddl, but log need be transformed and saved properly to file and than commited. What is your opinion about postgresql iteration tools?
Not exactly like Red Gate's tool, but check out http://www.liquibase.org/. Might pique your interest considering your topic.
Maybe Post Facto is similar to what you want.
Another PostgreSQL Diff Tool (apgdiff) sounds like it works a lot like Red Gate's SQL Source Control and SQL Compare:
Another PostgreSQL Diff Tool (also known as apgdiff) is free
PostgreSQL diff tool that is useful for comparison/diffing of database
schemas. The tool compares two database dump files and creates output
with DDL statements that can be used to update old database schema to
new one or to see in what exactly both databases differ.

Is there a nice tool that allows for easy comparison between 2 Sql-Server databases ?
For example, I'd like to do dev DB vs. live DB comparison to see what objects
(view, stored procedures, tables ...) have been modified in dev.
I know I can just run a script that compares system files, but I am hoping there is something nicer out there.
There's lots of options:
Red Gate SQL Compare is my favorite, but ApexSQL has one (SQL Diff) as well. Also, Nob Hill Software has one.
If your DB has a way to dump its definitions without the data to a text file, the diff tool would be a low tech way to solve this.
Might not be ideal, but all the tools you need will very often already be installed on your server.
Short answer as I'm on the phone, sorry.
I have two databases that are similar, but not the same. DB 1 is the old one and DB2 is the updated one with lots of new tables, columns, procs, constraint etc.
I need to write an update script in order to update DB1 database. These databases have lots of tables and stored procedures. Is there any way to get the differences in two database other than manually.
Buy red-gate's SQL Compare. You wil never regret spending the money.
There are a number of software tools (e.g. Red Gate) that enable you to compare databases easily.
Also, try this script; it's free and it should also work.
Cheers
To pile on to everyone suggesting Red Gate's tool, it should be noted that this tool can generate scripts to update the second database.
The awesome thing about red gate (besides the fact that they're an SO sponsor...) is that if you have the SQL Toolbelt with an active subscription, you will automatically get any new tools added. They recently released SQL Source Control, and I got it included as part of my SQL Toolbelt subscription.
Working on a team where people are prone to amending dev SQL Server tables and forgetting about it, or preparing a change for deployment and having to wait for that deployment. This leaves our dev and live tables inconsistent, causing problems when SPROCs are pushed live.
Is there a tool whereby I can enter a SPROC name and have it check all tables referenced in it in the dev and live DBs, and notify of any differences?
I know two excellent tools for diffing SQL database structures - they don't specifically look inside stored procedures at their text, but they'll show you structural differences in your databases:
RedGate SQL Compare
ApexSQL's SQL Diff
Redgate also has a SQL Dependency Tracker which visualizes object dependencies and could be quite useful here.

For SQL Server 2005/2008, Open DBDiff works pretty well. The great part about this is that it's free. Also note that I am writing this answer for version 0.9 which currently works for SQL 2005/2008.
It'll show you the differences between the database schema between a source database you specify and the destination database you specify. There are also buttons you can click that can update or create the table that is in question.
I would recommend SQL compare and SQL Data Compare from Redgate Software. I worked with these tools for several projects and they did a great job. Documenting changes is also a good thing to do, but some changes are to complex to write your own SQL code for (including juggling data around between tables).
The redgate tools create scripts in a matter of seconds and those scripts are almost always correct (some older versions had a hard time with table dependencies in big databases, but when playing around with the statements (in a begin transaction / rollback) I was able to quickly fix those problems).
Another strong point in the redgate suites is that you can save your comparison project. This is especially useful when you don't want to convert a certain table (or data), you can exclude them. When loading the project the next time the software will automatically ignore those tables.
One disadvantage is the cost of the software (smaller companies I worked with did not want to buy the software). SQL compare and SQL data compare together will cost you about 800 dollars, but if you look at the time you will save when releasing you will save a lot of money. There is also a trial you can play around with (30 days I believe).
SQLDBDiff is a nice and user-friendly and lite tool.
SQLDBDiff supports SQL Server 2000 to 2016 and also SQL Azure.
SQLDBDiff available with both free with limited use and full with a trial.

Try Microsoft Visual Studio Database Edition aka Data Dude (formerly for Database Professionals). It'll do a complete schema comparison and generate the necessary scripts to upgrade the target schema.
Of course, this shouldn't replace a proper build process ;-)
If you need a quick schema comparison tool for SQL Server, you should take a look at dbForge Schema Compare for SQL Server.
I've made a MssqlMerge utility that allows to compare (and merge) MSSQL database data and programming objects. It also allows to search for particular word or phrase across table definitions and programming objects.
RedGate makes a tool for Microsoft SQL Server that allows you to snapshot the difference between two databases. It generates the scripts needed to update the database schema while preserving the data.
I need to find a tool like this for the Firebird database. We use Firebird in an embedded fashion, and would like to push out schema updates to remote machines with as little hassle as possible.
I don't know of a tool for Firebird that does exactly the same.
However, FlameRobin allows you to extract the metadata for single database objects or the complete database. It can also create scripts to recreate a certain database object including its dependencies. So you could either diff two database creation scripts and save the differences as the starting point (which may still need some changes), or you could use the recreation scripts for a single object and its dependencies.
This list contains a couple of comparison tools
As #devio suggsted, I took a look at the large list of administration tools listed on the IBPhoenix site. Of the tools on the list, the only two that generate scripts to migrate schema and data changes are XCase and Database Workbench.
Does anyone have experience with these tools? Are there others that I may have missed?
Embarcadero Change Manager will add support for InterBase and Firebird in the fall. Read all about it here. Change Manager includes schema archive compare and synchronizations, data compare, sync, and masking, and configuration management.
see IBExpert, it have a command line tool too where you can run scripts in a propietary language. You can compare two db and get the script to update the target db, it does a great job with dependecies, like views, it drops every dependency where the view is used, alter the view and then recreate the dropped objects. This can be done in GUI too, and a lot of other nice things
Migration tools for Firebird on IBPhoenix site are on a separate link Contributed Downloads - Migration Tools
Try SchemaCrawler link
SchemaCrawler is an open-source Java
API that makes working with database
metadata as easy as working with plain
old Java objects.
SchemaCrawler is also a command-line
tool to output your database schema
and data in a readable form. The
output is designed to be diff-ed with
previous versions of your database
schema.
As it requires a JDBC driver, you would also need the following: Firebird JDBC Driver
My company has a number of relatively small Access databases (2-5MB) that control our user assisted design tools. Naturally these databases evolve over time as data bugs are found and fixed and as the schema changes to support new features in the tools. Can anyone recommend a database diff tool to compare both the data and schema from one version of the database to the next? Any suggestions will be appreciated: free, open source, or commercial.
I use Red Gate Sql Compare for comparing schemas. It also has an interesting feature that allows you to save a snapshot of the schema which you can then use in later diffs. for example compare the schema of today with the schema of a month ago.
I use ApexSQL Diff. It is an excellent tool for doing just what you're describing...compare schema, compare data, generate change scripts. It not free, but it works well.
NOTE: ApexSQL Diff only works with SQL Server.
We never actually purchased it as we ended up using SQL Server 2005, but DBDiff seemed to do the trick: http://www.dkgas.com/downdbdiff.cgi
It works with any ODBC compatible DB.
I've used Total Access Detective in the past and it did the trick. It's a while ago though so you might want to investigate first...
If you're looking for a free alternative to Red Gate's most excellent SQL Compare, you might want to check SQLDBDigg made by SQLDBTools. It's what I used until I caved and bought SQL Compare.
It's not a perfect solution, but I often export both databases as txt/SQL files and then use a diff program, such as the one that comes with TortoiseSVN. You can then see all of the differences. It doesn't automatically create the SQL though to sync the dbs.
