Database Query Optimizer: AI-Powered SQL Performance Analysis
Paste a slow query — get an optimized version with index recommendations and execution plan analysis.
Slow Queries Kill User Experience
A single unoptimized query can bring your application to its knees. The SQL Optimizer analyzes your queries, identifies bottlenecks, suggests indexes, and rewrites queries for maximum performance.
How It Works
Paste your SQL query and optional schema. The AI analyzes the execution plan, identifies full table scans, missing indexes, and suboptimal joins, then produces an optimized version.
import vincony
client = vincony.Client(api_key="YOUR_API_KEY")
slow_query = """
SELECT u.name, COUNT(o.id) as order_count, SUM(o.total) as total_spent
FROM users u
LEFT JOIN orders o ON u.id = o.user_id
WHERE o.created_at > '2025-01-01'
AND u.status = 'active'
GROUP BY u.name
HAVING SUM(o.total) > 1000
ORDER BY total_spent DESC
"""
result = client.tools.sql_optimize(
query=slow_query,
dialect="postgresql",
schema={
"users": ["id (PK)", "name", "email", "status", "created_at"],
"orders": ["id (PK)", "user_id (FK)", "total", "status", "created_at"]
}
)
print(result.optimized_query)
print(f"Estimated speedup: {result.speedup}x")
for rec in result.recommendations:
print(f"• {rec.type}: {rec.description}")
# • INDEX: CREATE INDEX idx_orders_user_created ON orders(user_id, created_at)
# • REWRITE: Move WHERE clause before JOIN for early filtering
# • HINT: Consider materialized view for this reporting queryIndex Recommendations
The optimizer doesn't just suggest indexes — it provides the exact CREATE INDEX statements, estimates the storage impact, and warns about write performance trade-offs.
Multi-Dialect Support
Works with PostgreSQL, MySQL, SQLite, SQL Server, and Oracle. Dialect-specific optimizations like PostgreSQL's partial indexes or MySQL's covering indexes are handled automatically.
# Analyze query patterns across your codebase
analysis = client.tools.sql_optimize.analyze_patterns(
queries=extracted_queries,
dialect="postgresql"
)
print(f"Queries analyzed: {analysis.total}")
print(f"Optimization opportunities: {analysis.opportunities}")
print(f"Potential latency reduction: {analysis.latency_reduction_pct}%")Pricing
5 query optimizations/month on Free. Unlimited with schema analysis on Pro and Enterprise.
