📝 Summary

The SQL query attempts to aggregate H1B approval and denial data for Amazon, but there are several issues with optimization and formatting. The subquery is unnecessary as it duplicates the main query logic, and there are inconsistencies in GROUP BY usage. Formatting can be improved for readability.

⚠️ Concerns

• Unnecessary LEFT JOIN with a subquery that duplicates the main query logic.
• GROUP BY clause only includes h1b.Fiscal_Year, but SELECT includes h1b.Employer, which may cause errors or unexpected results depending on SQL dialect.
• WHERE clause uses LIKE 'AMAZON', which is equivalent to = 'AMAZON' and may be misleading.
• Formatting is inconsistent (e.g., indentation, spacing around operators, and SQL keywords).
• Ambiguous use of table aliases and column references.
• No clear use of the joined subquery's results in the main SELECT.

💡 Recommendations

• Remove the unnecessary LEFT JOIN and subquery; aggregate directly from the h1b table.
• Update the GROUP BY clause to include both h1b.Employer and h1b.Fiscal_Year if both are selected.
• Use '=' instead of 'LIKE' for exact string matching.
• Improve formatting: align SQL keywords, use consistent indentation, and add spaces around operators.
• Remove unused subquery columns from the SELECT statement.
• Add comments to clarify the purpose of the query if needed.
