Description This course provides students with the technical skills required to write basic Transact-SQL queries for Microsoft ® SQL Server ™ 2000. This is a new two-day course. The course content reflects the need to focus on querying with Transact-SQL. The material comes primarily from course 833, Implementing a Database Design Using Microsoft SQL Server 7.0. This new course is a prerequisite for course 2073A, Programming a Microsoft SQL Server 2000 Database and course 2072A, Administering a Microsoft SQL Server 2000 Database. Audience This course is designed for SQL Server database administrators, implementers, system engineers, and developers who are responsible for writing queries. Student Prerequisites This course requires that students meet the following prerequisites: Experience using the Microsoft Windows ® operating system. An understanding of basic relational database concepts, including: Logical and physical database design. Data integrity concepts. Relationships between tables and columns (primary key and foreign key, one-to-one, one-to-many, many-to-many). How data is stored in tables (rows and columns). For students who do not meet these prerequisites, the following course provides students with the necessary knowledge and skills: Course 1609, Designing Data Services and Data Models Familiarity with the role of the database administrator. viii Querying Microsoft SQL Server 2000 with Transact-SQL Course Objectives At the end of this course, the student will be able to: Describe the uses of and ways to execute the Transact-SQL language.
