SQL Server DBA Roadmap: SQL Developer Path

Create a Stored Procedure

Write a stored procedure that returns all orders for a given customer ID.

Expected output: A stored procedure that accepts a customer ID and returns matching orders.

Hint: Use parameterized input and SELECT statement with WHERE clause.

Analyze Query Execution Plan

Run a complex query and analyze its execution plan to identify potential improvements.

Expected output: A report detailing query bottlenecks and suggested optimizations.

Hint: Look for scans, expensive operators, and missing indexes.

A clustered index determines the physical order of data in a table, while a non-clustered index is a separate structure that points to the data rows.

You analyze the query execution plan, check for missing indexes, rewrite inefficient joins or subqueries, and update statistics.

Stored procedures are precompiled T-SQL code blocks stored in the database. They improve performance, security, and code reuse.
