T-SQL for Data Analysts (Basic + Advanced) (English)

Description

In the training "T-SQL for data analysts (basic + advanced)" we cover T-SQL, the query and design language for Microsoft SQL Server, Azure SQL Database and Azure Synapse Analytics. We focus on making analyzes in SQL, and preparing, linking and enriching datasets for use within other analysis tools. From the broad experience of data analysis, the trainer shares examples, and has numerous "puzzles" ready that help to really understand SQL better. We conclude with the very powerful concepts of windowing , ranking , subqueries and CTEs . As a data analyst you can efficiently perform and solve all kinds of analyzes with this.

This training consists of two separate parts, which can also be followed independently of each other:

• T-SQL for Data Analysts (DP-080)
• Advanced T-SQL for data analysts

• Audience

  This course is aimed at data analysts, data engineers and data scientists who want to support their work by leveraging the power of SQL for advanced data analytics.

  Skills gained

  After this two-day training you will be able to:

  • Use SQL Server query tools (Azure Data Studio, SQL Server Management Studio)
  • Write SELECT statements to retrieve columns from one or more tables
  • Join tables using JOIN statements (and really understand what's happening)
  • Sort and filter data
  • Use built-in SQL functions to analyze data
  • Grouping and aggregating (summarizing) datasets
  • Modify data with T-SQL, using INSERT, UPDATE, DELETE and MERGE
  • Structuring complex SQL queries with Common Table Expressions
  • Smart sorting and using Windowing and Ranking functions
  • Transform datasets using Pivot and Unpivot
