Major Tips to Crack SQL Queries & Earn Your Microsoft Certification

Learning SQL queries is a fundamental step that will open many opportunities in data management, data analysis, and data processing fields with artificial intelligence. As data environments become more diverse and cloud-based SQL platforms such as Azure SQL Database are used more frequently, individuals must be more focused when working with SQL. Here are some useful tips that would assist you in cracking SQL queries more effectively.

Before constructing queries, make sure you understand the data structure: 

First of all, it is necessary to recognize the table structures, data types, and table dependencies. Understanding how data is stored and connected enables one to come up with proper and efficient queries.
Build things at a basic level at first, then more complex:
Start from simple SELECT statements and then add new joins, filter using WHERE clause, and aggregation. This approach makes it easier to detect problems and also keeps the queries in a reasonable size.

To improve readability, use aliases:

Table and column aliases also help in reducing the length of your query especially if the table names are long or if the query involves several tables.

Study JOINs with examples from the real world:

Learn how to use INNER, LEFT, RIGHT, and FULL OUTER JOINs in practice to know when and how each type is applied. This will help you gain confidence and acquire the relevant skills.

Practice composing CTEs and subqueries:

Subqueries and Common Table Expressions (CTE) are two tools that help to divide a complex query into easily understandable sub-problems. They will help you to avoid repetitiveness within your queries by making them modular.

Always use intelligent data filtering:

WHERE clauses and filters should be used as soon as possible to reduce the amount of data to be processed, especially in large databases. Filtering is also recommended before JOINs or GROUP BY operations to enhance performance.

Pay close attention to GROUP BY and aggregate functions:

Learn how to apply SUM, COUNT, AVG, MIN, and MAX with GROUP BY to produce useful summaries of data. These are practical skills often included in exams and in actual working environments.

Be cautious while using ORDER BY:

ORDER BY is resource intensive. It should only be used when required, and when sorting the fields, only the relevant ones should be sorted to avoid a lot of computation.

Know how to handle NULL:

Understand how SQL works with NULLs in comparison, consolidation, and filtering. Therefore, the NULL can be managed by using functions as like ISNULL or COALESCE.

Use query plans or EXPLAIN to test and optimize:

Some of the tools that you can use are the SQL Server’s Execution Plan. This is useful in helping you find out areas where your queries are taking much time and, therefore, redesign them to be more efficient.

Match the topics of your certification exam to what you are learning:

The Microsoft exam skills for DP-900, DP-300, and DP-700 exams must be reviewed to determine which types of SQL queries are included. This helps keep the preparation on track.

Practice with Azure SQL and other Microsoft platforms:

Many Microsoft certifications incorporate Azure environments, so it is advisable to practice the SQL queries on Azure SQL Database or Azure Data Studio.

Conclusion 

As technology advances, SQL remains a fundamental tool in 2025 that data professionals use to perform their basic functions in cloud computing, business analytics, and AI. Learning SQL queries not only helps you in handling and analyzing data but also opens the door to achieving international Microsoft certifications such as DP-900 (Azure Data Fundamentals), DP-300 (Azure Database Administrator Associate), and DP-700 (Microsoft Fabric Data Engineer Associate).
