Do your reports take forever to load? Do you feel held hostage by the IT department every time you need new data?
It's time to cut out the middleman. "SQL for Power BI Analysts" isn't an academic textbook on server administration; it is a survival manual for the modern Data Analyst.
Written specifically for professionals transitioning from Excel and Power BI, this book skips complex DBA theory and focuses 100% on Analytical SQL: the ability to read, filter, and transform data directly at the source.
What you will master:
End the Loading Spinner: Learn to filter data before it crashes your machine.
The VLOOKUP Killer: Master JOINs to merge massive tables in seconds.
Smart Aggregation: Use GROUP BY to summarize millions of rows before importing.
Source Cleaning: Use CASE WHEN to handle errors and create categories without touching Power Query.
Pro Integration: Finally understand DirectQuery vs. Import and the Query Folding myth.
Become the professional who solves performance issues in minutes, not days. Reclaim your autonomy today.
