[sql] What is best tool to compare two SQL Server databases (schema and data)?

I would like to compare two SQL Server databases including schema (table structure) and data in tables too. What is best tool to do this?

We are using an inhouse developed solution that is basicly a procedure with arguments of what you want included in the comparision (SP's, Full SP code, table structure, defaults, indices, triggers.. etc)

Depending on your needs and budget, it might be a good way to go for you as well.

It is quite easily developed as well, then we just redirect output of procedure to textfiles and do text comparisions between the files.

One good thing about it is that its possible to save the output in source control.

Try DBComparer, it's free and fast:

http://dbcomparer.com/

Database Workbench can made it too

http://www.upscene.com/products.dbw.index.php

Cross database development

Use the Schema Compare and Migration Tools to compare testing and deployed databases, migrate existing databases to different database systems.

you can also made it with database Comparer

I use it for Firebird and it works well.

I've used SQL Delta before (http://www.sqldelta.com/), it's really good. Not free however, not sure how prices compare to Red-Gates

I'm partial to AdeptSQL. It's clean and intuitive and it DOESN'T have the one feature that scares the hell out of me on a lot of similar programs. One giant button that it you push it will automatically synchronize EVERYTHING without so much as a by-your-leave. If you want to sync the changes you have to do it yourself and I like that.

I tried OpenDiff Tool . Great tool that is free and easy to use .

I would definitely go with AdeptSQL if you're using MSSQL. It's the least good looking but the most talented db compare tool amongst the ones I've tried. It can compare both the structure and the data. It tells you which tables exist on one db but does not exist on the other, compares the structure and data of the common ones and it can produce the script to synchronize the two. It's not free but has a 30 day trial (as far as I can remember)

dbghost is the best i have used to date. one of the best features i have seen is that it will generate SQL code to go between versions of a database based on the SQL you keep in source control, as well as a database. simple and easy to use.

Try dbForge Data Compare for SQL Server. It can compare and sync any databases, even very large ones. Quick, easy, always delivers a correct result. Try it on your database and comment upon the product.

We can recommend you a reliable SQL comparison tool that offer 3 time’s faster comparison and synchronization of table data in your SQL Server databases. It's dbForge Data Compare for SQL Server and dbForge Schema Compare for SQL Server

Main advantages:

SQL Admin Studio from http://www.simego.com/Products/SQL-Admin-Studio is now free, lets you manage your SQL Database, SQL Compare and Synchronise, Data Compare and Synchronise and much more. Also supports SQL Azure and some MySQL Support too.

[UPDATE: Yes I am the Author of the above program, as it's now Free I just wanted to Share it with the community]

I use schema and data comparison functionality built into the latest version Microsoft Visual Studio 2015 Community Edition (Free) or Professional / Premium / Ultimate edition. Works like a charm!

Red-Gate's SQL data comparison tool is my second alternative:

_{(source: spaanjaars.com)}

• http://www.red-gate.com/products/sql-development/sql-compare/
• http://www.red-gate.com/products/sql-development/sql-data-compare/

There is one tool with source code available at http://www.codeproject.com/Articles/205011/SQL-Server-Database-Comparison-Tool

That should give flexibility as code is available.

I've used Red Gate's tools and they are superb. However, if you can't spend any money you could try Open DBDiff to compare schemas.

I like Open DBDiff.

While not the most complete tool, it works great, it's free, and it's very easy to use.
