Il corso DP-080 Querying Data with Microsoft Transact-SQL potrebbe interessare a chiunque avesse bisogno di scrivere query SQL o Transact-SQL di base.

Questo include chiunque lavori con i dati come, ad esempio, data analyst, data engineer, data scientist, database administrator o sviluppatore di database.

Potrebbe anche essere utile per chi è coinvolto solo marginalmente con i dati, o che vuole imparare di più sul lavoro con i dati, come solution architect, studenti e manager tecnologici.

Per partecipare con profitto al corso DP-080 Querying Data with Microsoft Transact-SQL è necessario che gli allievi abbiano:

• esperienza di lavoro con i database relazionali;
• conoscenza di base dei sistemi operativi Windows e delle loro funzionalità principali.

Frequentando il corso DP-080 Querying Data with Microsoft Transact-SQL si otterranno le seguenti capacità:

• utilizzo degli strumenti di interrogazione di SQL Server;
• programmazione di istruzioni SELECT per recuperare colonne da una o più tabelle;
• ordine e filtrazione i dati selezionati;
• utilizzo di funzioni integrate per restituire i valori dei dati;
• creazione di gruppi di dati e aggregazione di risultati;
• modifica dei dati con Transact-SQL usando INSERT, UPDATE, DELETE e MERGE

Module 1: Getting Started with Transact-SQL

In this module you will learn about the basics of the Transact-SQL (T-SQL) language, as well as general properties and terminology of relational databases. This module will also introduce the basic SELECT statement for retrieving data from a table.

Lessons

• Introduction to Transact-SQL
• Using the SELECT statement
• Lab : Get started with SQL Server query tools and writing queries in T-SQL

Module 2: Sorting and Filtering Query Results

In the module you will learn how to control what data is returned, the order in which it is returned and how to use the ORDER BY clause, with and without paging. You will learn about various kinds of filters that can be used in the WHERE clause to control which data rows are returned and how to manage the results by removing duplicates with DISTINCT.

Lessons

• Sorting query results
• Filtering the data
• Lab : Sort and filter data returned by SELECT queries

Module 3: Using Joins and Subqueries

In this module, you will explore T-SQL queries which access data from multiple tables with various kinds of JOIN operations and simple subqueries.

Lessons

• Using JOIN operations
• Using subqueries
• Lab : Write queries with JOIN operationsLab : Write SELECT statements using subqueries

Module 4: Using Built-in Functions

In the module you will explore the use of built-in functions for returning computed or special values in the SELECT list or in the WHERE clause. Functions include math functions, string functions and system functions. There are other types of functions that will be mentioned, but not discussed in detail. You will also learn how to combine rows of data into a single group, providing summary information for the group such as SUM, MIN or MAX.

Lessons

• Getting started with scalar functions
• Grouping aggregated results
• Lab : Built-in functions

Module 5: Modifying Data

In this module, you will learn the T-SQL statements for modifying table data including UPDATE, DELETE and MERGE as well as various options for INSERT including creating a new table with data from an existing table. You will also look at how to have the system automatically supply values for columns as the data is inserted.

Lessons

• Inserting data into tables
• Modifying and deleting data
• Lab : Modify data
