Querying Microsoft SQL Server (20461)
About this Course
This 5-day instructor led course provides students with the technical skills required to write basic Transact-SQL queries for Microsoft SQL Server 2014. This course is the foundation for all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence. This course helps people prepare for exam 70-461.
This course is intended for Database Administrators, Database Developers, and Business Intelligence professionals.
