I am using Red-Gate's software: http://www.red-gate.com

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:

I like Open DBDiff.Updated Open DBDiff Link

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

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'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.

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.

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.

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

Try DBComparer, it's free and fast:

Database Workbench can made it too

Cross database development

Use the Schema Compare and Migration Tools to compare testing and deployed databases, migrate existing databases to different database systems. Windows 7 product key free.

you can also made it with database Comparer

I use it for Firebird and it works well.

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:

• Speedier comparison and synchronization of large databases
• Support of native SQL Server backups
• Custom mapping of tables, columns, and schemas
• Multiple options to tune your comparison and synchronization
• Generating comparison and synchronization reports

Plus free 30-day trial and risk-free purchase with 30-day money back guarantee.

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.

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 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)

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

APPLIES TO: SQL Server Azure SQL Database Azure SQL Data Warehouse Parallel Data Warehouse

This topic describes how to create a schema in SQL Server 2017 by using SQL Server Management Studio or Transact-SQL.

Before You Begin

Limitations and Restrictions

• The new schema is owned by one of the following database-level principals: database user, database role, or application role. Objects created within a schema are owned by the owner of the schema, and have a NULL principal_id in sys.objects. Ownership of schema-contained objects can be transferred to any database-level principal, but the schema owner always retains CONTROL permission on objects within the schema.

• When creating a database object, if you specify a valid domain principal (user or group) as the object owner, the domain principal is added to the database as a schema. The new schema is owned by that domain principal.

Security

Permissions

• Requires CREATE SCHEMA permission on the database.

• To specify another user as the owner of the schema being created, the caller must have IMPERSONATE permission on that user. If a database role is specified as the owner, the caller must meet one of the following criteria: membership in the role or ALTER permission on the role.

Using SQL Server Management Studio

To create a schema

1. In Object Explorer, expand the Databases folder.

2. Expand the database in which to create the new database schema.

3. Right-click the Security folder, point to New, and select Schema.

4. In the Schema - New dialog box, on the General page, enter a name for the new schema in the Schema name box.

5. In the Schema owner box, enter the name of a database user or role to own the schema. Alternately, click Search to open the Search Roles and Users dialog box.

6. Click OK.

Note

A dialog box will not appear if you are creating a Schema using SSMS against an Azure SQL Database or an Azure SQL Data Warehouse. You will need to run the Create Schema Template T-SQL Statement that is generated.

Additional Options

The Schema- New dialog box also offers options on two additional pages: Permissions and Extended Properties.

• The Permissions page lists all possible securables and the permissions on those securables that can be granted to the login.

• The Extended properties page allows you to add custom properties to database users.

Using Transact-SQL

To create a schema

1. In Object Explorer, connect to an instance of Database Engine.

2. On the Standard bar, click New Query.

3. The following example creates a schema named Chains, and then creates a table named Sizes.

4. Additional options can be performed in a single statement. The following example creates the schema Sprockets owned by Annik that contains table NineProngs. The statement grants SELECT to Mandar and denies SELECT to Prasanna.

5. Execute the following statement, to view the schemas in this database:
