  2. Querying Data with Transact-SQL


    This course is designed to introduce students to Transact-SQL. You will learn about: T-SQL elements, writing SQL queries, querying JOINs, sorting and filtering data, SQL Server 2016 data types, T-SQL DML, built-in functions, grouping and aggregating data, subqueries, and set operators.


    Delegates will learn how to

    • Describe key capabilities and components of SQL Server 2016.
    • 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.
    • Add programming constructs such as variables, conditions, and loops to T-SQL code.
