Instance Environment friendly SQL Queries

Think about this state of affairs: discovering all orders positioned within the final month.

Poor Efficiency:“`sqlSELECT

FROM orders WHERE order_date >= DATE(‘now’, ‘-1 month’);

“`

Improved Efficiency:“`sqlSELECT

FROM orders WHERE order_date >= (SELECT DATE(‘now’, ‘-1 month’));

“`

The second instance pre-calculates the date, making it extra environment friendly than continuously recalculating it inside the `WHERE` clause.

Efficiency Optimization Methods Abstract
