Microsoft has a number of SQL Server certifications available for you, and in this article I will help you to choose the best one for you.
SQL Server Certifications
The first one is 98-364 Database Fundamentals. As the name suggest is most suitable for people who are new to SQL Server or those who some experience with SQL Server and would like to learn more and get a certificate.
Next one is Microsoft 70-461 Certificate Querying SQL Server. This one is for people who have 2 or 3 years solid experience with T-SQL, and it's essentially for T-SQL Developers as it covers not just querying (T-SQL SELECT statement) but all aspects of T-SQL Development.
There are more certificates available and I will update this page soon.
