T-SQL for data analysts (DP-080) (English)

Description

In the basic training "T-SQL for data analysts" 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.

With these two days, this training is particularly suitable to master T-SQL with a focus on data analysis.

Audience

This course is suitable for anyone who wants to learn how to write basic SQL or T-SQL queries. No special prior knowledge is required. Both people who have to process data from their primary role (Data Analysts, Data Engineers, Data Scientists, Database Administrators) and people who have to deal with SQL adjacent to their role (solution architects, technical management) can participate in this training.

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
