MOC 20761: Querying Data with Transact-SQL

Learn basic Transact-SQL queries for Microsoft SQL Server 2016.

This course is designed to introduce students to Transact-SQL. It is designed in such a way that the first part of the content can be taught as a course to students requiring the knowledge for other courses in the SQL Server curriculum.

Što ćete naučiti

  • Describe key capabilities and components of SQL Server.
  • Describe T-SQL, sets, and predicate logic.
  • Write a single table SELECT statement.
  • Write a multi-table SELECT statement.
  • Write SELECT statements with filtering and sorting.
  • Describe how SQL Server uses data types.
  • Write DML statements.
  • Write queries that use built-in functions.
  • Write queries that aggregate data.
  • Write subqueries.
  • Create and implement views and table-valued functions.
  • Use set operators to combine query results.
  • Write queries that use window ranking, offset, and aggregate functions.
  • Transform data by implementing pivot, unpivot, rollup and cube.
  • Create and implement stored procedures.

Kome je namijenjeno

  • The main purpose of the course is to give students a good understanding of the Transact-SQL language which is used by all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence.
