True sets contain unique elements. Ben-Gan emphasizes using primary keys and unique constraints to ensure your physical tables reflect mathematical relations.
Itzik argues that most performance problems arise because developers write queries based on physical intuition (thinking about hard drives and loops) rather than logical processing (thinking about sets). itzik ben-gan t-sql fundamentals
The book dives deep into the building blocks of data. Ben-Gan provides comprehensive coverage of SQL Server data types, including character strings, collations, date and time functions, and numeric scales. He emphasizes the critical importance of avoiding implicit data type conversions, which can severely cripple query performance by invalidating database indexes. 3. Subqueries and Table Expressions

Understanding how to filter data accurately (using WHERE ), sort it (using ORDER BY ), and apply logical operators. Furthermore, mastering Data Manipulation Language (DML)—specifically INSERT , UPDATE , DELETE , and the powerful MERGE statement—is taught with an emphasis on data integrity and avoiding common pitfalls like logical bugs tied to null values. 2.
