SQL parameters are placeholders defined by the end-user, which allow for controlled analysis and filtering of data. They can be used to set values such as date ranges, numeric fields, or strings, enabling users to create dynamic queries and visualizations tailored to their specific needs. This feature reduces adjustment time, making data-driven decision-making more efficient and accessible. By utilizing SQL parameters, organizations can optimize resource allocation, operational efficiency, customer experience, strategic decision-making, and marketing efforts, ultimately leading to improved performance and competitiveness.
