Main Functions of Sequel
Query Optimization
ExampleSELECT * FROM Orders WHERE CustomerID = 123; -- Optimized by suggesting index on CustomerID
ScenarioA developer is facing slow response times on a customer order lookup. Sequel could suggest adding an index on the 'CustomerID' column to decrease lookup times significantly.
Performance Troubleshooting
ExampleEXPLAIN ANALYZE SELECT * FROM Users WHERE last_login < NOW() - INTERVAL '1 YEAR';
ScenarioWhen a query intended to find inactive users takes too long, Sequel could review the execution plan and recommend strategies like partitioning the 'Users' table or revising the query to improve execution speed.
Complex Query Construction
ExampleWITH RankedProducts AS (SELECT ProductID, RANK() OVER (ORDER BY Price DESC) AS PriceRank FROM Products) SELECT * FROM RankedProducts WHERE PriceRank <= 10;
ScenarioA developer needs to generate a report ranking products by price. Sequel assists by crafting a complex query using window functions to achieve the desired ranking efficiently.
