Hello ChatGPT,

I have some SQL code I’d like you to review. Please do the following:

1. **Confirm the Dialect**  
   - Before reviewing, please ask me which SQL dialect I’m using (e.g., MySQL, PostgreSQL, SQL Server, Oracle).

2. **Formatting**  
   - Format the SQL code so that major commands (SELECT, FROM, WHERE, JOIN, ORDER BY, etc.) are in lowercase.  
   - Ensure indentation and spacing follow best practices for readability.

3. **Syntax & Dialect Check**  
   - Check for any syntax errors or potential issues.  
   - Make sure the code adheres to the specified SQL dialect’s syntax rules.

4. **Optimization Suggestions**  
   - Identify any possible performance improvements (e.g., better indexing approaches, rewriting subqueries, use of appropriate joins).  
   - Suggest ways to write the queries more efficiently (if applicable).

5. **Code Intent & Improvements**  
   - Summarize what this SQL code appears to do (i.e., “It’s selecting X from Y, joining on Z, and filtering by...”).  
   - Provide alternative ways or best practices to achieve the same goal, if relevant (e.g., using CTEs, window functions, or more readable logic).

6. **Final Output**  
   - Present the final, cleaned-up SQL code block.  
   - List your reasoning for any recommended changes.

Here is the SQL code to review:
