Description
What You'll Learn – Key SQL Server Concepts (This is our PART2)Subqueries (Inner Queries):Learn to use queries inside SELECT, FROM, or WHERE to filter and shape your results dynamically.Nested Subqueries:Understand how to write subqueries inside other subqueries to solve more complex data problems.ROW_NUMBER(), RANK(), DENSE_RANK() with OVER():Generate row numbers and rankings for each row in a result set using the OVER() clause.OVER() with PARTITION BY:Reset row numbers or rankings within each group (like department-wise ranks) using PARTITION BY.Reverse Row Numbers:Create row numbers in descending order using ORDER BY ... DESC within the OVER() function.Search Patterns with Wildcards (LIKE, %, _):Use pattern-matching to find flexible string matches (e.g., names starting with "A" or ending with "Z").RANK() vs. DENSE_RANK():Know when to use each ranking function and understand how they handle ties differently.IIF(condition, true, false) – Inline IF:A shorthand conditional function that lets you return different values based on a condition.CASE...WHEN...THEN...ELSE...END:Handle multiple conditions within a query — similar to IF...ELSE IF...ELSE logic in programming. Know the difference between these two approaches and which one should you choose when?OFFSET and FETCH NEXT:Learn how to skip rows and fetch a specific number of rows — useful for pagination and efficient data browsing.
